I agree. I'm still running the stock cast pistons, block...etc. This is my 3rd motor. The first 2 I got crazy with timing and such. If you tune it right you can run this dog piss out of it. I made 342 at 25 lbs. but went rich at 4500 rpm so the car would not pull good past 5K rpm. I made 390 TQ. I believe I would have broken, or have gotton very close to 400 whp if it would have pulled past 6k rpm. But there again, my tune is VERY conservative. Not to mention the Holset hy35 is not the turbo to do it. This is my 2nd one, And I rebuilt this one already because the rear seal got cooked. I now run 16ish lbs, the "OL hy35 can't handle 25lbs for long I guess?
