Thanks Wayne;

When I posted my summary on Getrag, I could not find another past posting that I
remembered wherein it was indicated a US firm was making these, and if I remember
correctly, transfer case replacements as well. True? or No? ......For the Getrag record

Subject: RE: Team3S: Advice needed on boost gauge installation

The hose at the plenum (intake manifold) which senses manifold pressure for
the fuel pressure regulator sees boost and vaccuum.  That is the correct
place to tap in for a boost gauge since that is what the engine is actually
seeing and is typically what the user would expect to see also.

Monitoring before the TB will show boost but not anything below atmosphere
and also will show boost when the engine is not actually under boost.

He (Jim) is having the output shafts and x-fer case mating female part
(whatever it's called) made in both spline sizes. He is not sure what
material is being used. I've seen the finished part and it looks pretty
good as far as manufact. quality goes. I just recently posted this info,
thats probably why you didnt find it when you were looking. Hope this helps

The company that makes the transaxle's VCU (Viscous Coupling Unit) for
Getrag (it IS subcontracted out) is in Italy and is called "GKN".  The
output shaft connects directly to the VCU, and may be made by GKN
also...

Water injection done properly could help somewhat I think.  Would be a
hassle to actually do it but could help.  Unsure how MUCH, how much more
boost could run with same octane.  The company making the quality unit
isn't at all specific about that either, I corresponded with them months
back.

GT Alley is out of business? I've been off the lists for several months so I
am a bit behind the times here.

What happened? Why did he go out of business?

What is he doing now? Does he still have the 3000GT?

Just to clarify, my position on aftermarket exhaust is:

a) an aftermarket exhaust won't make a heck of a lot of difference when
running 1.1 bar or less of boost

b) significant performance improvements from an aftermarket exhaust
system can really only be realized when the ENTIRE system is replaced
from the turbos back

It should be very revealing and I plan to post the results early next
week.  But considering recent threads on this list and Mike's recent EGT
readings, it would seem that money would be better spent on fuel
delivery upgrades rather than a cat-back exhaust system.

My '94 TT developed an annoying stumbing problem immediately after
installation of the Blitz BOV that may be related to the above.  At the
moment I prefer the stumble to the hoot, but I'd rather have a car that
doesn't hoot OR stumble, as this distracts me from my heat shield
resonating and my lifters ticking!  :-|

Description of the behavior: If I accelerate and then lift off of the
throttle completely, about one second later, the car will stumble
momentarily (ie- it bucks slightly, more noticable in lower gears of
course).  If I accelerate and then push in the clutch as I lift the
throttle, about one second later the RPMs will drop WAY down (250 rpm?)
momentarily and then come back up to normal idle.  If I downshift to
bring the RPMs up, there is no stumble.  If I give it just a tad of gas,
staying out of the boost, then it usually does not stumble when I lift
off.

So, I figure the problem must be either the vacuum lines or the intake
hoses.

The Blitz BOV hose is now hooked into the front fitting on the intake
plenum along with the stock BOV hose and the SAVC-R solonoid hose.  I
assume that the fuel pressure regulator's manifold pressure hose is
attached to the rear plenum fitting, but is all of the hose now hanging
off the front fitting somehow causing a fuel delivery problem under the
conditions described above?  Too much air, not enough fuel...

Or, is it more likely that the Blitz BOV is venting too much of the
intake under the conditions descrived above?  Too much fuel, not enough
air...

Or, is it more likely something else?

TIA for any suggestions you might have!

Subject: Team3S: Plug Gap Theories

There has been some reference to potential HP gains by reducing plug gap.
The only reason to reduce plug gap is if your engine is missing out at high
boost/rpm.  Best performance will occur with the largest gap you can run and
still maintain a spark.  The tricky part is when you start to push boost, it
makes it harder for your stock ignition to cross the plug gap.  If this is
happening, you will notice it as an engine miss.  If your engine is not
missing out at high rpm, than changing the gap won't make any difference.

Subject: Team3S: Questions:  4WS, custom exhaust, motor flush

(my apologies if this is a double post.  I didn't see it come up on
the list, and assumed the first try got black-holed because my
address wasn't set correctly.)

Greetings,

First off, let me say....  THANK YOU!  I signed up for the "other"
lists several months ago, and have had to wade through 99%
crap to find the occasional nugget of useful knowledge.  This
list is all I ever wanted in trying to obtain info on my VR4!

I have been lurking on this list for a little over a month now,
and decided it is finally time to speak up.  I have a stock 91 VR4
with 107K on it (although only 45K on the engine).  I have three
questions that hopefully aren't too lame for this list.

Q1: As far as I can tell, the previous owner probably smacked the
right rear lightly, probably hiting a curb.  I have replaced the
stub axle and the rotor on that corner.  The problem now is that
it won't align properly.  Apparently, the right rear is at it's
max adjustment and is still out of spec.  The measurements are:

    FL  -.7   Camber   FR  -.3
        3.7   Caster       3.9
        -.1     Toe       -.02

    RL -1.2   Camber   RR  -.9
        .09     Toe        -.50

The alignment guy told me to go to a body shop and have it lightly
pulled (where the control arm mounts?), and then he'd try again.
So here's the question:  Is he missing anything on the 4WS that
needs to be disconnected to take accurate measurements?  I do trust
the shop (and him), so I'm inclined to believe his recommendation.

btw, the reason for all of this is that the steering on the car is
extremely jumpy on uneven and rough road.  It does have Michelin
MS300 all seasons that are pretty worn (and a little uneven) but I
can't attribute all of the steering problems to them.  The really
strange thing is that it's not as bad when the back end is loaded
with weight.  ie. full gas tank and stuff in the cargo area.  The
really really strange thing is that the behaviour isn't consistant.
It never actually goes away, but it manifests itself in a varying
amount of "jumpiness".  This last bit makes me wonder if whatever
controls the rear steering is not operating properly.

I haven't been able to get the car on a rack to check if anything
is out of whack, but the guy from from the body shop said he could
visually see that the wheel wasn't tracking straight (4WS aside).  I
have been under it, and nothing appears to be bent or damaged, but
I doubt I have the critical eye for this type of diagnosis.

any specific suggestions on what to ask or request?


Q2: I had a main cat gasket blow out, and took it to a local exhaust
place to replace it.  (The bolts were frozen and I wasn't about to
break one trying to do it myself.)  While I was there I asked about
a custom replacement, and the guy said I could do it really cheaply
if I only replaced the pipes from the Y to the tips.  The question:
does replacing the section between the cat and the Y matter that
much?  In other words, what does a cat back system like the Borla
gain you over a minimal custom replacement as I suggested?


Q3:  I noticed a few people recommending using a motor flush as part
of a process to eliminated lifter ticking.  I have used Gunk motor
flush many times in the past (on other cars), but stopped after I
heard that it would do bad things to internal seals.  Any truth
or rebuttle to this?


Thanks for allowing me to ramble..  Sorry for the long post..

I'm sure you'll get ample feedback on the other queries, so I'll limit my response to
this: Gunk worked well for me...took out the tick...and I'll likely use it if required
again. I expect this will not have to occur for some time. Using it on regular basis
(like at every oil change) may in fact cause seal problems. The problem with the
necessity for such a repeated flush scenario is that the interval between changes is
probably way too long, or the oil is not synthetic and is baking under high temps (be
sure and allow idle for a couple of minutes before shutdown). Use synthetic, change it
often, and do not shut down immediately upon reaching your parking spot..

FWIW , it would better serve the list and the archives if you post questions separate,
under separate subject headers.

It sounds like BRE is doing something to the AWD tranny on the Eclipse/Talon
to improve shifting.  I'm thinking they MIGHT be doing something to the
synchros - modifying them, substituting from another car, making new ones,
etc.

...which brings up a question: does Getrag make tranny components for the
Eclipse/Talon as well as our cars? Just wondering.

Q2: I had a main cat gasket blow out, and took it to a local exhaust
place to replace it.  (The bolts were frozen and I wasn't about to
break one trying to do it myself.)  While I was there I asked about
a custom replacement, and the guy said I could do it really cheaply
if I only replaced the pipes from the Y to the tips.  The question:
does replacing the section between the cat and the Y matter that
much?  In other words, what does a cat back system like the Borla
gain you over a minimal custom replacement as I suggested?

<end of snip>
===============================
Dave...

re: Q2: I believe the catback exhaust netted me very little hp gain. Borla
and GReddy make claims of 10%, which is unlikely. There was a noticeable
improvement in several areas when I replaced the downpipe and removed the
cat (for off road use). However, this was "seat of the pants" measurement.
We have three owners in Europe who are going to an all wheel dyno soon. One
does not have exhaust mods, two have complete exhaust mods. It will be VERY
interesting to see the results. Think of it in terms of the hose analogy. If
you increase the pressure on the front end, you're limited to the flow of
the smallest diameter piece of hose, whether it's at the beginning, in the
middle, or at the end. Personally, my advice is to do the whole system,
particularly if you're planning on turbo mods at some point.

BTW...I'm with Darcy on his response to the motor flush question (and his
suggestion to break your questions into discrete posts).

Hi Jim,

as does my AVC-R.  Actually, so does my MASC =)  I need to perform the Bob

Anyway, stuff interjected below.

I would suspect pressure bearing inlet hoses first.  Vaccuum lines can cause
problems too but in my experience the problems are a little less noticeable
unless severe, like one completely falling off or cracked all the way
through.  Small pinholes cause more subtle problems IME.

Double and triple check those pesky hoses between the Blitz pipe, rubber
connectors and the stock bypass valve.  They can be deceptively snug and
still leak.  Sometimes it is difficult to see that they are crooked.  Make
sure the hoses are installed "straight on" as in not cocked at an angle and
that all clamps are quite snug.

The FPR hose is on the rear of the plenum (on the engine side of the TB) and
is easily distuinguishable since it runs back to the fire wall to the FPR
(beside the stock boost solenoid).  The hose at the front of the plenum
should have a T in it now after the blitz installation.  The Blitz goes to
the front line which attaches to the plenum and then off to its original
location.  If this is not so then perhaps that is the source of your
troubles.

Possible I suppose but it would have to be backed way off were that to be
the case.  How is it adjusted now?  You can try to tighten it up by
loosening the lock nut and turning the adjustment screw clockwise (down)
which will make it take more pressure before it blows off.  Don't turn it
too far though.  The maximum adjustment is somewhere where the screw sits
just ever so slightly above the lock nut.  Mine leaks a little above 18-20
PSI or so.  There is a stiffer spring available to remmedy this.

> Or, is it more likely something else?

I would suggest that it has something to do with the Blitz installation.
Recheck everything and see what shakes out.

In a message dated 99-01-27 18:20:13 EST, you write:

<<
 btw, the reason for all of this is that the steering on the car is
 extremely jumpy on uneven and rough road.  It does have Michelin
 MS300 all seasons that are pretty worn (and a little uneven) but I
 can't attribute all of the steering problems to them.  The really
 strange thing is that it's not as bad when the back end is loaded
 with weight.  ie. full gas tank and stuff in the cargo area.

Dave, my '91 VR4 has very new Michelin tires and was recently aligned. The car
tracks perfectly straight, but I do notice some steering "jumpiness" as you
describe on worn pavement. There is some construction in my area where new,
perfectly smooth and flat pavement leads to older worn pavement. On the new
pavement, the car tracks perfectly. As soon as I hit the old pavement, the car
wants to veer of to one side or the other - I have to literaly hold the car on
centerline.

The worn pavement is so old you can actually see where years of traffic has
created two grooves or low spots where the tires contact the road. The
"jumpiness" gets worse with braking and less under acceleration. This is
consistent with your observation of improved steering when the rear of the car
is loaded.

I think it might have something to do with wide tires wanting to crawl up the
side of the low spots in the pavement. It is something I first noticed while
driving a Toyota Supra I used to own that also had wide tires and gave the
same braking/acceleration responses as the VR4.

Actually, the VR4 is a bit more jumpy than the Supra was during steady state
driving (no accel/braking). I have a theory for this. Consider that the AWD
transmission is supposed to deliver more power to the rear wheels than the
front. During heavy acceleration there is no doubt that all 4 wheels are
pulling forward - 55% power to the rear wheels and 45% power to the front (I
think those are the correct numbers). Under this condition the steering is
stable. But let off the gas and the car wants to dart left or right.

If the rear wheels are getting more power than the front, the rear ones must
be continually trying to "outrun" the front wheels somehow (at least that is
how my brain is trying to interpret this idea). I'm wondering if the AWD drive
system might be causing the front wheels to RESIST forward motion during low
power cruising - giving a similar steering response to slight braking as far
as the front wheels are concerned. My gut tells me this is nonsense, but...
hmmmm...

Of course the other thing is the fact that the VR4 is much wider than the
Supra, placing the tires further towards the outer edges of the grooves in the
worn pavement. THAT is probably the real source of the handling difference
between the two cars.

Anyway, once you do get your car straightened out, you may still have
difficulty steering on worn pavement as I do - unless of course there is
something wrong with my car as well. (Hope not!)

Those headlight conversions are available. I inquired about the pricing on
them and I was informed that they would cost $730 for the Set of lights.
This is kinda reasonable. Considering headlight conversion kits cost $100,
plus if you bought two sets of catz lights at $250 each, it would come out
to around this pricing. Plus this comes with all the necessary hardware.
I did find a product which allows you to control how high your popup
lights come up from in the car. Sorta like an electronic boost controller.
That price is roughly $150.

Subject: RE: Team3S: Questions:  4WS, custom exhaust, motor flush

Actually, the front diff is slightly higher geared (lower numerically) than
the rear so that the front end pulls the car along a wee bit.  This is
common practice in 4WD pickups also.  It is done so that the rear end
doesn't want to swap ends so easily.

AWD/4WD vehicles tend to want to wander a bit anyway.  Since the front
wheels are driving wheels they tend to pull up on irregularities in the
road.  This phenomenon is exacerbated by wide tires.

Remember that the VR4 (and 3K/S in general) has a very pronounced forward
weight bias which can make the car feel a little more excitable under
certain situations.  This is not a big deal though.  I have literally had my
car airborne at over 135 MPH (on a rather rough road with many dips and
curves - my favorite local test road) without any nasty behavior from the
car and that was with the stock suspension.  I would not do this on purpose
again nor suggest that anyone try it but the car handles amazingly well for
what it is.

If the car is truly being extremely jumpy then there may well be something
wrong with the suspension.

Barry

They "don't all do that".  That's a dealer cop out for either not knowing
what the problem is or not wanting to fix it.

It could be a number of things.  Debris left over in the bell housing from a
previous clutch, a failing clutch, a bad machining job on the flywheel,
marginal throwout bearing and possibly even maladjustment.  I have assumed
that it is not the transmission itself since sometimes it is not easy to
tell.  If it IS the transmission then something just isn't right and that
would likely mean replacing it.

So who knows for sure without having someone competent check it out.  Sadly
it sounds like your dealer isn't interested.  I've heard that story several
times on different items.  In only one case was the problem found and that
was after I pressed hard.  Even then they missed fully resolving the problem
(cracked engine mounts) because they missed one and the problem wasn't
totally resolved until I discovered it myself.  Any turbo related problems
you may as well do it yourself as in my experience (4 for 4 dealers so far)
they are clueless as to their workings.

I'd be inclined to drive it for a while and bug them again if it doesn't go
away as the (presumably) remanufactured unit wears in.

Maybe I am in the wrong city for Mitsu deals ;)  Hopefully you will have
better luck.

Subject: Team3S: Clutch/tranny problems...

** High Priority **

Hi there...

New to the board, but I read some messages about clutch problems that
caught my eye, and I figured I'd throw in my $.02....
I had a Centerforce dual friction clutch installed 4 months ago, on
my 92 Stealth TT. A few weeks ago, I noticed a squeaking noise under
the hood. It didn't sound like it was a belt, so I took it to the
dealership and had them inspect it. They determined that it was the
throwout bearing, although I can hear the squeaking noise even when
in nuetral. Funny thing is, sometimes it is louder than usual, and it
doesn't seem partial to a hot OR a cold engine.
Apart from all that, I hear a chattering when the car is in nuetral,
but when I disengage the clutch, it goes away. I took the car in to
the clutch shop I had the Centerforce installed, and they pretty much
told me they don't hear any problems at all. The chattering only
occurs when the car is cold.
About the only thing I can think of that fits all these symptoms is
that they milled the flywheel a little too much, or it has some
runout. Unfortunately, I'm having a problem in getting someone to
diagnose and repair the problem.

Any thoughts?

I'm assuming "pull" implies acceleration.  my problems occur more while
coasting or braking.  I agree that the tires are an issue, but I have driven
plenty of HUGE tired vehicles including numerous 930's and a 94 VR4 that were
nowhere near this bad.

exactly what I'm trying to determine! :)  I guess I'm trying to find out what
might be damaged or malfunctioning to cause such abnormal behaviour.  I was
hoping someone would say "hey, I had the same problem and it was the xxx part."
I also realize that there are a number of variables to isolate. 

I guess I'll give the body shop a try and see what they can determine.

Subject: Team3S: Bought a T connector

Thanks to everyone that replied to my need for help with connecting my boost
gauge.  I bought a brass T connector from Wal-Mart last night.  It fits on
the rubber hoses in my car perfectly.  I'll probably do the complete install
of the gauge tonight or this weekend.  Then its time to think about that
boost controller.

Thanks again

Subject: Team3S: Fuel pressure

Hi

Are our fuel pressure the same all the time or does the pressure increase if boost and RPM change?

If pressure changes, what is it that controlls it's function?

What's the stock fuel pressure on  a VR-4?

How high pressure shall be used with 15G turbos? (560 injectors)

Hi Dave;

Barry seems to have covered the gambit with his response/s, however, excessive or
erratic wander, particularly with uneven pavement (where similar vehicles do not) may
mean it's time to check your suspension components ...bent tie rods, worn ball joints,
etc. Either of these could cause something of the problem you note.

Best

Subject: RE: Team3S: Fuel pressure

The VR4 FPR is boost dependant.  Actual fuel pressure measured in the fuel
line before the injector changes with boost.

The injectors require a differential pressure between the inlet and the
outlet side of 36-45 PSI in order to operate correctly.  That means the fuel
pressure must be increased to compensate for each 1 PSI increase in boost.
The stock FPR does this more or less but based on observation may top out
too soon.  Could be other factors though too like fuel line and even the
fuel pump that ultimately limit what pressure can be maintained.

The required fuel pressure is 36-45 psi plus 1 psi for every psi of boost.
At 15 PSI manifold pressure you need 51-60 psi fuel pressure *at the
injector*.  You really don't need more pressure (than that described by this
1 PSI for each PSI of boost) unless you are attmpting to use fuel pressure
to adjust mixture.  This can be done but it is imprecise and not the desired
approach.

Note that this is regardless of turbo or injector size.  Pressure is one
thing, flow (capacity) is something completely different and equally as
important as the pressure.

Stock FP is around 43 psi at idle and 0 vac., 36 psi with a bit of vacuum as
I recall.

15Gs and 560 injectors require a good sized pump (280-320 lph).  Furthermore
and at least as importantly that fuel pump must be able to deliver the
required FLOW of fuel at the required LINE pressure, not injector
differential pressure.  Example, 90 gph @ 43 psi is great for idling...hehe.
You need to know what that 90 gph pump can put out at the required fuel
pressure for your desired boost level, which is more like 56-60 PSI line
pressure.   Most fuel pumps have a pressure point at which they become less
efficient.  Either pressure or flow will need to drop at that point.

Barry
