I was told by a local garrett dealer that 22-23psi is pushing it on the gt2871r, also the GT30 carries the same shaft as these and should be ran no more than 22-23 as well.

smelly240 · 12-02-2008, 07:55 AM

25 is easily doable on a 3071r... its well within the compressor efficiency.

Pushing the relm of making power <> pushing the safe limits.

It should continue to maker power to the 22/23 psi level, but I don't forsee it being bad on the turbo to goto 25psi....it'll still flow hot air, so I could see torque figures being higher, not so much HP once you go beyond 22/23 psi

Anyone running the t3 yet?

Sileighty_85 · 01-01-2009, 10:16 AM

but Made 363whp and 332ft-lbs Torque on Stock Cams @ 1.5bar

My tuner says it feels faster than 360, so im excited i cant wait to feel the power >_<

Holy Shit, 363whp on stock cams...

How high is your compression?

i also have a 2871r sr20 red top, i'm still on stock cams.
you jus made me wanna see what mine will put out on stock cams.lol
only difference is i have apex 1.1mm, stock internals, Greddy Intake manifold, E-manage blue, i have no a/c or p/s. im jus waiting to get 740cc injectors.

you shoukd make a little more with that intake manifold throw in some 264 Cams and you should be pretty close if not hit 400

djcobra · 01-01-2009, 05:24 PM

I have to say those are nice Numbers, especially with stock cams. However, i still can't believe it... Were these numbers from the 'Dynojet' ?

My car put down ~330whp with 302 wtq at 15-16 psi.

Supporting mods include:

S14 Kouki SR20DET Motor (stock bottom)
GT28RS
HKS Step 2 Cams 256in/264ex
HKS Step 2 Valve Springs
HKS 555cc injectors
Peakformance Retainers
Apexi 1.1mm Headgasket
Splitfire Ignition System
Z32 MAF
Power FC
SARD FPR
RPS Max Street Clutch

and all that other crap... Mind you my turbo is just a lil smaller than yours... Anyways, nice numbers.

Crank that shit up to 20 pounds, you will see the difference, prolly 360+ whp

djcobra · 01-01-2009, 07:44 PM

I'm going to pretend that I didn't read your post 'S13 curtis' boosting over 18 psi on this turbo is just plain stupid and not to mention out of efficiency range.

Steve.

BiG MiKE86 · 01-02-2009, 06:48 AM

Well boyz I just changed out my Fuel pump because it started screaming like crazy - Im hoping this fixes my previous problem of not being able to go past 15psi - because I noticed as the pump got worse the level of boost I could hit got lower and lower - Back to the dyno! O and nice numbers Sileighty 85 - thats sweetness man goodluck

S13 curtis · 01-06-2009, 08:18 AM

Looks like this guy got Cody Ace beat,Zilvia member.
.86 users please drool

http://zilvia.net/f/cars-sale/123696...pics-pics.html

Traped 124mph in a S14 chassis.

drftmark · 01-28-2009, 05:31 PM

I made 260whp and I *think* 248tq (don't have the graph next to me) at 16 psi. Does this seem low to anybody? It was on a Dyno Dynamics - I know its the heatbreaker dyno but I was just wondering.

s15 sr
JE forged pistons
HKS step 1 256/256 cams *Eliminated VTC* (was this a mistake? should I buy a 256 intake cam that I can put the VTC back on?)
Stock exhaust mani
3in turbo elbow + dowpipe + exhaust *no cat*
apexi FMIC
sard 850cc's
gt2781r .86

Questions:
1)Does this seem low?
2)would VTC make me see a bigger gain?

slider2828 · 01-28-2009, 05:34 PM

Yes that seems very low on a .86 GT2871R... What ECU you using? WHo is tuning for you

Opps forgot to include that

Its a Haltech E8

A reputable shop with a good tuner tuned it.

JeremyR · 01-28-2009, 05:37 PM

jesus thats like 100hp too low for the setup you have...

stock s15 sr makes like what 250ish??

somethings wrong...

drftmark · 01-28-2009, 05:43 PM

I am thinking my piston rings could be blown. OR when I had the engine rebuilt the shop could have ordered different size CR on the JE pistons. BUT I don't think they messed up.

ALSO note this was on a dyno dynamics

fromxtor · 01-28-2009, 05:46 PM

My motor is almost done(just need to install cams etc), and I cant wait to drop this bitch in the car. I also have a spare block I am going to get hot tanked, honed, re-surfaced, for a more agressive setup later after my driving skill improves.

Check your compressions.... wow at 16psi... still low...

I think that does seem a bit low... I made 330/298 @ 15psi on a similar setup (S13 + 256/256) GT2871r .64

Start Troubleshooting.. goodluck

See whats weird and I see all these numbers and my car doesn't make nearly what i think it should then...

@ 22psi I only made 335 HP // 305 TQ

drftmark · 01-29-2009, 11:52 AM

^ I am in the same boat. Just a wtf moment.

drftmark · 02-01-2009, 01:09 AM

Here are my dyno sheets. My compression is 140/130/140/140, so my second cylinder is a little iffy. I put some oil in it and it went up to like 180+.

Here is the HP/TQ
