Those are some of the major stuff, do i need to upgrade the valves/springs and retainers?? Im not planning to over rev it, but i want at least 350-400hp, i know that you dont need them unless you planning to rev over redline and some say you'll need it no matter what...so im confuse now....Big Turbos Guys i need some help. thanks

Upgraded valvetrain is always good for high hp setups whether its turbo or all motor.

Having a strong valvetrain will prevent valve float at high RPM. and especially when boosting, you want a bit more RPM over stock to take advantage of more boost.

 

Sounds like im upgrading the springs/retainers, will stock valves hold fine?

 

stock valves will work fine. of course upgrade to better flowing valves will be better, but as far as NEED. its not needed at this time.

how high do you plan on reving?

 

Alright, thanks exospeedAMcrx.

Like i said say up there im not planning to over rev it, just stock redline.

 

id upgrade just for peace off mind knowing the motor will continue to run strong, just my opinon tho

Exactly. You put in so much money into your setup. a good valvetrain is a preventative measure since stock valvetrains have already gone through their wear and tear through the years.

 

not to mention, but extra insurance against broken retainers

 

u need some titanium retainers bud
