i'd get 2.5" piping

 

clutch is rated by torque not hp and stage 2 is good for about 425+ torque so im good, next step will be twin disk.


^this

my tuner said that with my setup 2" is closer to optimal volumetric efficiency than 2.5 would be especially seeing as my intercooler is pretty big and might see a little drop.

 

yes

 

Yes that is correct most are measured by torque and when I was making 325 torque my stage 2 clutch didn't hold up for long. I think I got about 7 months out of it. But maybe I just drive my car to hard lol. A twin disk will be nice step up tho I wish I would have bought a twin from the start.

Mabey you did drive it a little too hard, red line shifts and fast engagement are killers.

 

so the dealership wanted to charge me 29.50$ for each bolt, crazy high.
so i called hardtopguy seeing as they have these at a decent price, got all 4 shipped 2day express for 72$ even.

 

Nice good deal. Its great piece of mind . Gotta do all you can to protect your engine !

 

Yea thats my main concern, im actually going a little on the conservative side with the build in hopes of not destroying my engine,
keeping boost at about 10psi, my tuner is also going to keep it a little on the rich side, might not quite put down what im hoping for but if i hit 350whp ill be happy with that, anything over that will just be a bonus.

 

It should be do-able. The 60-1 may not be a top choice of S2k owners and I think is a little older ? But its a very capable turbo and should allow you to hit your goals

Hows your manifold look ? That will help as well since its not a log style

 

individual runners, front mount stainless steel.
pretty well built, but kinda ugly lol.
but it looks promising as far as power,
i actually like the turbo i have for quick spool and decent power within my goal.
and its upgradable to BB and a bigger hot side when im ready.
