k i want to go turbo but would like to do a buidl up on my motor. i dont want to bore it out, i want to leave stock size on everything. i have a chance to get some b18b valve springs and retainers for free by trading something that i dont really need. keep in mind that my cars going to be a daily driver and occasional 2-3hr trip driver. as far as the turbo build up im looking to do a t3 fast spool boosting about 10.

 

You need to give more info for your post. What motor are you running? What exactly are you asking?

Yes a stock motor will take 10 psi assuming it is safely tuned.

What does b18b valve springs gotta do with anything, am I missing something here?

If your cylinder are scored badly or out of round then most likely you will need to overbore.

 

just cancel this post, no more turbo. o and i have a ls motor
