would you happen to have a pic of your set up. thanks

Ninjabread · 09-27-2008, 07:09 PM

This was a long time ago, just so i could move the car, dont mind all the mess, its cleaned up now

it's REALLY tight back there, i have to install the turbo/mani and WG as one piece, then go under the car and bolt on the turbo outlet, the dump pipe, and then i can put the rest back on. The hose for the crank case breather litteraly touches the dump tube so its wrapped in anti-heat stuff.

ninjabread - is it just me or does your WG vacuum run to your brake booster????

nevermind....it just looked like it was.

efrain240sx · 09-27-2008, 08:21 PM

ninjabread- that is a very nice set up you got there, I'm going to have to copy you.

oops i forgot to mention my freddy intake manifold. is it possible with the manifold and 272's?

BiG MiKE86 · 09-28-2008, 11:35 AM

SO my numbers are in:
319RWHP 256RWTQ @ 16 PSI
330RWHP 298RWTQ @ 18PSI

Had soo many problems on the dyno *5.5 Hours*

Greddy RS BOV was opening at high boost... AVC-R was malfuctioning... Couldnt read/turn up boost

I was really hoping for more power. We feel that something is really holding this car back - my tuner feels that either the FMIC + Piping are tapped (at their limit) or the exhaust is (highly doubtful)

Exhaust:
Tomei Expreme Manifold
Circuit Sports Downpipe
Test Pipe
Buddy Club Spec II Catback

Cold Side:
Greddy VSPL (about 2 yrs old)
Apexi Filter and 3" aluminum Pipe

Ill scan My dyno Sheet @ work tomorrow morning

Z33dori · 09-28-2008, 11:40 AM

i think you answer is in some cams

Those torque numbers seem kind of low.

I thikn it's a great combination. IN reality, the 264 HKS would be every bit as fun too. That limit was set by JWT, who through testing determined it was a safe limit. Springs will enable slightly more RPM, but now you fight limits of the factory HLAs.

Im internally gated on 264's at 16psi. I have a vac and exhaust leak so it fluctuates but still reliable. External is a waste. There is a reason Garrett made these internal.

I had everything, and tried everything with my internal gate. New Garrett Actuator, new HKS actuator, new Forge Actuator, preloaded, not preloaded, boost controller gain stitting all over, MBC...nothing would give me consistant low boost (12-16 psi). Some would hold 20psi, but only when new....

Would have a different manifold maybe helped? Who knows...would have different cams helped? Who knows. I have a greddy elbow, and a 3" RSR exhaust....there is just a certain point where that little quarter sized hole just can't vent enough.

Garrett also initialyl rated them as a 350 whp turbo. Guys with .86 housings are hitting 450 at big boost.

I don't think Garrett ever thought about how well the turbo would actually work on some applications.

tomei 256 11.5 cams

tomei 740 cc
tomei reytec ecu
tomei fpr
with FMic ,boost cotroller, fuel pump.

Hard to say with that ECU...but for the most part, over 350 whp @ 18 psi.

A turbo can make whatever PSI it mechanically can. If you were to take the vacuum line off your wastegate, I bet these things could flow 30psi with no wastegate vent at all. Obviously at that point it's hurting the turbo, and probably just breathing hot air...but its' possible.

No offense, but I think you're fighting a tuner issue. With the slightly higher compression, and overbore, that thing should easily be making over 360 whp at 18 psi. Were your valves installed correctly, and lapped/machined in?

Creizai · 10-02-2008, 12:55 AM

So whats the wastegate deal to run between 14-20psi solid? I currently have a manual XS that doesn't spike at ALL during any drifting on my t25. I can however go EBC if I need to.

None taken - I had the head done by a machine shop so im not sure if he installed the valves correctly.. Could it be that my timing is off a tooth? I was really expecting more like the 360 range myself.. Here is my dyno sheet sorry for the crappy quality

BiG MiKE86 · 10-02-2008, 02:53 PM

I just purchased a new Solenoid and Boost sensor for my AVC-R and a new spring for my BOV.. See if that changes anything - Hey where are you guys reading you boost from? Hotside or Cold Side? What hose? Ive got a Defi Boost guage t'd off the BOV near the turbo - is that correct?

I think you need to have a tee in the fpr line for your boost gauge.

I have a stock SR20 with 2871r, and running and AVC-R.....I am at 285-290 ft-lbs tq by 4000 RPM.....it looks like your power is coming on a little late?

s15specR · 10-02-2008, 03:27 PM

Just dyno'd at 17.5 I got 332hp on a dyno dynamics, spiked a little when we played with the settings/gain on the EBC a bit on and got 349hp, then after about 3 hours trying to figure the timing out we relaised the plug gap was throwing it off, few more pulls it stayed at 332-337hp. The shop said the didnt feel comfy going over 18psi in and SR without running race gas.

How much HP/TQ @ what psi are you putting down? Yeah the dyno chart does look like its hittin a bit late... idk

OBEEWON · 10-02-2008, 05:18 PM

Cody, I hope you submitted those photo's. I would say we should get together for a shoot but the track has not been kind to my car.

Camo · 10-03-2008, 02:33 AM

can someone explain to me why some of you guys run 256/264 cams vs. 264/264s and which combo has the best results? Im pulling my head off to build it and Im trying to make sense of this all before I order anything. Also, at what point would I need solid lifters? the tomei 270s?

Man, I wish those guys would post up! Thats the whole reason I made this thread.

Do you have anymore info? What boost levels are they hitting at?

was that shop scared that they were going to blow your motor ???
you have enough fuel for it ??

I think they didn't want to push it to much, new shop, great guys etc etc...but yeah I think they didn't want to push it. One of the owners said he doesn't tune anything over 18psi on pump.

What's up with yours you were gonna put it on the dyno a while back....

I haven't had time I been busy with work and weekend drift events.
lately my car has been running on the hot side !! (around 190-210)
I think my thermostat is going bad !! I'm gonna swap it out and switich to water wetter and distilled water and see how it goes. I also need to put a O2 bung in the downpipe so i can take it to WOLF and get tuned. I promise you that as soon as it get tuned and dynoed I will post up !!

WoolyS14DET · 10-03-2008, 10:50 AM

s15specR ====

whats temp is your car running at and are you using a stk fan clutch setup or are you using electric fans ??

s15specR · 10-03-2008, 02:17 PM

I'm running FAL thermo set at 75 celc (176), it got up to 90 celc (194 faren.)and stayed there most of the 4hrs on the dyno. For a period of time towards the end one of there fasn pointing towards the car got unplugged. Another thing I noticed was the heat soaking, the cold pipe was almost as hot as the hot side. So we called it a day right then.
