Im building a z6 and i was wondering how much power i can get out of my stock sleeves and crank before they are worthless...its going to be boosted.
Thanks

 

It depends on how well the engine was built and tuned. The crank is super strong from the factory, the sleeves are a diffrerent story, but may be more than enough, depending on your goals.

Stock sleeves, stock crank, forged pistons/rods, with a nonvtec head and stock cam.

Well im wantin to atleast be right around 300-350 hp.

 

are you using forged internals on stock sleeves or stock pistons rods and sleeves? completly stock block ide say maybe 225 250. forged slugs and rods ide say would be more reasonable for 300whp.

 

Ya im going to be running tuner toy rods and vitara pistons.....with stock sleeve and crank?

 

Also whats a good valve train? I'm kinda new when it comes to all this stuff.....I have a turbonetics t3/t4 ball bearing turbo....i just need alot more stuff but im going to broke because of college...
