Subject: RE: Team3S: Team3S Power Steering Leak
Best way I've found to get at ALL of the power steering stuff is to pull
the
motor.
But if that's not feasible, Try putting the car high enough up on
jack
stands that the underside of the car is at about chest level when
you're
sitting on the floor. Once you have that accomplished, remove the
driver's
side wheel and all of the plastic covers behind it. Now you should be
able
to reach up into that space behind the motor where all of the P.S.
stuff
lives. Don't plan on actually seeing what you're doing in there,
you're
pretty much going to be working by "feel".

Subject: Team3S: Do they make an aftermarket Headers
Hello all,
Well we need to get a new exhaust. We got the ATR downpipe already
but
we need to find out if there any company to make aftermarket headers
for
a 1991 3000GT VR4. Does anyone have any experience with this?

Nothing that really works. Only necessary if also another turbine housing
is
used and therefore the flange doesn't fit. Do something against the
restrictive pre-cats and the O2 sensor housings. Only seperated paths
for
the wastegate and turbine outlets work the best.

I have DN Performance on my car. They are made to go with the ATR down
pipe.
Dynamic Racing carries them. 505-439-1125 ask for Matt.

I first suspected that the Saner's link pin bolts were somehow
contacting
the axle flange bolt heads also. Would seem that could make that
clunk
sound and at that frequency. However, I have not found evidence of
that
happening. Several months ago I took digital pics with the purpose to
show
this team that the clearance is very very close (still have these but
never
posted em). I also had to use a narrow spacer and different length
link pin
bolt to gain clearance. One also must force the bar as far forward
(toward
the front of car) as possible before tightening down bolts - a two
person
job. The Saner rear sway bar is a contrary install but well worth the
effort.
I think I'll crawl back under there and look again for something more
subtle - such as the "tiny mark on the say bar" you mentioned. This
is a
puzzler. I never had this clunking noise before the Saner install but
that
could be attributable to my never pushing side load limits as much as I
am
able to do now.
I'll soon check out CV's and bearings as others suggested while I'm
back
there installing shocks (have Tein Flex coming my way)

Subject: Team3S: Exaust header heat shields
I'm getting ready to put my motor back into the car and I'm wondering if
I
really need the ugly heat shields. No matter what you do to them,
they look
like crap. Has anyone taken theirs off and lived to tell about
it?
Just curious,

Subject: Re: Team3S: Supercharger?
There is no bolt-on solution for a non-turbo DOHC engine. Before
adding any
forced intake (SC or TC), you'll need to drop the compression ratio to
below
9:1, and preferably to 8:1, like the turbo models have (your CR is
10:1).
Only the SOHC models (8.9:1 CR) can add a supercharger (or turbo)
without
changing the compression. The two most appropriate models of
supercharger are
made by Knight Industries out of Florida. One is a 5.6 psi (street
legal)
supercharger (~$4,500+), the other is a 9 psi (not street legal)
model
(~$6,000+). There are turbo kits being offered around on the net, but
the
cost of upgrading your car to get them to fit (and to work) will cost you
more
than trading in your car and buying a turbo model. People have tried,
and
failed. Even if you *did* get it to work, you still wouldn't have
AWD, AWS or
the other electro-mechanical goodies that make the turbo models so
spectacular. One guy spent close to $20k trying to 'upgrade' his DOHC
to a
twin turbo and he still couldn't get it below 13 seconds for the 1/4
mile. He
sold it for less than $10k. In other words, don't waste your
money. Buy a
turbo model and be done with it, or be happy with what you've got.

You do not necessarily have to drop CR to add forced induction to a
3000GT non-turbo at 10:1 CR... In fact, I have done some research
and
found there are many other cars with high CR motors that have
supercharger and turbo kits available... For instance, the new
Celica
GTS, 11:1 CR from the factory, and two companies sell turbo kits for
them, granted you are limited to about 7 psi of boost, but it is still
a
viable option... There is no reason you couldn't do the same with
a
10:1 6g74, so long as you monitored knock and such...

Right, you don't _need_ to lower your compression, but the amount of boost
you can safely run is
severly limited. But it's a trade off, lower compression you loose hp but
can increase boost adding hp. High compression gives more hp but less boost.
Personally I'd rather have 10:1 compression in my vr-4 and run lower boost. imho

Personally, if I had a lot of time on my hands, I would drop the
compression to 7:1, or something like that, and run 20 psi. I like more
horsepower.
The more boost - the more stuff goes into the cylinder and burns there,
hence more horsepower. The tradeoff when you lower you compression is a
rougher idle and bad fuel economy, but I have not seen rumpa-rumpa 3/S cars
yet with rough idle problems. Strange, everyone who thinks about fiddling
with their compression tries to go the VTech way and hike it through the
roof. Why, I don't know.

Even if you got through all the compression, boost, and knock questions,
you
would still need traction.
N/A DOHC cars have torque steer already. With more power to the wheels, you
would need big muscles to keep the wheel where u want it at WOT.
They sold AWD N/As in Japan, but not here. . .pity.

It's a great academic exercise to discuss other cars, and the logic that
such
high-CR mods are *possible*... But they are definitely not a safe
option for
us, according to Thomas "Geoff" Knight, who owns Knight Industries, and
makes
the superchargers I listed. He has tried them on both our SOHC and
DOHC (NT)
models. To paraphrase him, "you *must* work with an engine that has a
CR
*lower than* 9.1:1, and I'd rather see it in the low 8's, like the
turbo
models 8:1". "The SOHC models are actually better candidates for
a
supercharger than the DOHC models for that reason".
I'd trust his opinion over even the most logical supposition.
If you want to spend the rest of your car's life running it on
$5-per-gallon
110-octane unleaded, you *could* run at 10:1 without detonation, but I
can't
imagine that anyone would want that. If you've got a Jones to put
a
supercharger on a DOHC NT, do the engine work, IMO.

Subject: Team3S: New tires - Sumitomo HTR+ or Goodyear Eagle F1 GS-D3
I'm in the market for some new tires. I would like to go less
expensive,
but want something that will keep up with the Vr-4 (not sacrifice
safety,
handling, etc).
I've been reading mixed reviews (although mostly positive) on the
Sumitomo HTR+. Better reviews for the Goodyears, but they are also
$70/tire more expensive.
Any personal experiences?
