Default GT3076r on a sti stock block and stock clutch, Will I be okay?

I just last night purchased off of Bluefish his turbo kit, Its the perrin GT3076r kit with stealth FMIC and PE 850cc injectors, I am wondering if anybody can tell me if I will be okay for 20-30,000 miles after putting this on, The stock clutch and stock block on my car has 25,100 miles, Am I okay with a conservative tune to keep me safe or will these mods just toast my stock stuff? I dont have it in my budget to replace the clutch or have a built engine right now or anytime soon, I will rarily get on this until then but still want to install it.

And I know that the 25K that are on it now are real easy miles and mainly freeway never on it, I get on it once in a while because I hate seeing it say 2-4 miles a gallon on my AP when I get on it. I have been real nice to my car so far waiting for these mods, I wasn't too impressed with my previous mods of:
-cat-less downpipe
-cold air intake
-cat-back
-perrin equal length manifold
Ap v2.0

because I have been in faster WRX's then my car is now.

my car was ok at 20k miles with that setup. However, on a dynapak at 25psi on meth...the clutch slipped.

it was fine on the street but not on the dyno.

You'll probably be ok....but you'll never know until you get it on the dyno. If you're just running pump....that's even better for you.

My car has been running a GT3076R with the .63A/R for 20,000mi. 30k on the odo.

-Stock block
-Stock manifold
-Stock TGV's
-Blow Through set-up
-Perrin GT3076R
-750CC injectors
-Walbro 255 FP
-Perrin Stealth FMIC
-Turbo XS CBE (since perrins comes with the DP)
-ACT 6 Puck Clutch

380AWHP and 375WTQ on 16 PSI. Tuned by Tim Bailey.

It's reliable, although coating it and the rest of the piping would be very beneficial to keep hood temps down. Mine is coated and blanketed. Haven't had a problem yet

u bought Zachs car??

Shweet if so.


Stock clutch will not hold a gt30r. too much torque. u will be ok for a while, but will notice eventually. my stock sti clutch lasted about 10k after i upgraded to a green turbo.

Ouch! If I wasn't so turned away by the whole clutch being a lot of labor I would just go ahead and be ready to do that, But Im trying to keep both put off for a long time and do them together, Built engine and better clutch since the clutch will then be no problem once the engine is pulled

Does anyone know what the price of a clutch would cost to be installed on my STI, just the price of the Install Only, not the clutch itself?

From the dealer it's around $450.

problem is....dealerships across the country have different labor rates. Gives you a rough estimate though.

I've read that the stock clutch is good for 400 ft-lbs, give or take. I think you'll be okay as long as you drive relatively conservative.

FYI: no matter how fast you make your car, there will always be a wrx that is faster...

And what is the point of a big turbo if you "rarely get on it"? I would put on the turbo, etc. and start eating off the dollar menu so you can drive the **** out of your car and have some money to replace the clutch soon. but hey, that's just me.... there's no point in having a fast car if you don't drive it fast

My clutch lasted till I got home after the dyno tune. 378/378 pump and 421/475 e85.

Stock block... and yes, I expect the motor to expire before it's time. When...don't know, but I do know it's on borrowed time.

ACT's heavy duty does well for me. Skip 6-pucks, ect - too aggressive for street use.

6 pucks are actually way easy to drive. At least easier than people make it out to be. Same engagement point, a little stiffer pedal. Just don't bog it and you're fine.

conservative tune? its a gt30, it can be tuned with c16 and made a daily driver. its a big turbo compared to a stocker,but it the world of large turbos this is a small compressor.

so tune it and have fun, just dont worry about what could happen because no matter what mods you have, there are no guaranties

oh i for got to mention the stock clutch will hold 400-450 wtq, i've seen hp numbers all over the place. and as far as time lasting this is what people always for get, it doesnt matter how much torque a clutch an hold that determens the duration its the material its made of that makes a difference. i recoment a carbon ceramic (or full carbon -carbonetics- $$$ ).

but if you arent into spending $2500 for a clutch plus install then i recomend the clutch masters stage 4, but get the lightend fly wheel combo. st will make a huge difference in the throttle responce

its alot easyer to screw a clutch job then a rotated kit install. that tranny is heavy and if you dont center that clutch just right. also so i have over torqued the blots on a block on more than one occasion (torquing them to spec!) so watch the mechanic ever time you get a clutch job done. i can count how many times i have been there to see the oops of over techs.

Get the right tune and drive it right. You will be fine. You will need to replace the clutch though. It may last 20k miles depending on how you drive.

Just my .02, I'm not a fan of the clutch masters stg4. Have ~1500 miles on one. Been working on a write up, just never finished it.

I ran that seetup for 2 weeks and piston #4 let go. I thought it was okay on stock block.

Some are fine, some aren't. i can tell you it isnt cheap building an engine though, so you gotta face the fact that it is a possibilty.

I didnt think it was too aggressive at all, BUT I wouldnt recommend it since stop and go traffic REALLY made it wear out prematurely.

(9 months and 20 k miles, i drive a lot)
