that's exactly what I was thinkin. Also what u think the max psi on that turbo on ur setup would be.Quote:

Your absolutely right its not necessary to touch the heads. However, it would help a lot. For example in your case with a mild porting the heads would likely net you an extra 50-60hp. At your power levels that could mean .2 in the 1/4. Also it would increase the efficiency of the turbo dramatically meaning less heat. A simple swap to an NNBS intake with 90mm tb could add 40hp while again adding efficiency. As I am sure you have realized with boost most mods will have much more dramatic results than they would NA. Yes these things aren't necessarily needed, BC boost is going to help you make huge power without modding other parts. However, you may be sacrificing efficiency and leaving more power on the table. As for strength of stock rods. When everything else is setup right it would appear these rods are good to just about any boost level. Good AF minimizing knock and keeping things cool these stock rods seem to hold up under 25+ in many builds. Stock pistons are a much greater risk. Ring lands bearings or valve spring always seem to go first.Quote:

All great answers guys. Thank u all very much just need to get all my parts and start building lol.
I would personally listen to the guys the have been to 25psi on a stock block vs. the guys that think or read about.
I've heard of a lot of people saying that the stock rod bolts will hold as much as the rods will before letting go. Is this true?Quote:
