Piston slap
Hi Justen, I've followed your progress from time to time and love your car.
Don't get to disappointed with that engine yet!
I have just finished building a forged tt 1uz and put it back into my Soarer.
When I ordered the pistons, CP/ Carrillo sent me their recommended size for a...
Xr8tt do you have a build thread?
Thankyou for the ring gap measurements, I have used the same top of .025 but the second comp ring is already .029-.030 without any filing. I hope I don't get blowby.
More updates please. Have you run it on another dyno or just the one? These horsepower numbers are CRAZY high for 12 psi. I'm not doubting just shocked & looking at your setup to see why your getting such good numbers. Maybe you've just achieved the perfect combo of turbo and manifold back...

Also did you have your engine balanced? Is it worth it?
I'm also using std...
A bit off topic but how much piston to bore clearance would you guys run for forged CP pistons at std bore size in a twin turbo application??
The standard bores before honing are already .004" clearance with no real sign of bore wear,(no lips).
