do i need valve train upgrade when going turbo?
 

i have a 95 gsr that i am building up for boost around 15 psi with je pistons bore 81.5mm, crower/eagle rods, port and poslish head. I am basically keeping my head stock except for the port and poslish part and 3 angle valve job and was wondering if i need to get some upgrades on the valves, valves spring, retainers, valve guides, and rockers? If i do need to upgrade my valvetrain, should i get oversize valves(and what size is good for turbo)? This is going to be my daily driver for now.

Thanks

stock head is good for boost, I wouldn't rev past 8 grand though

I just got springs and titanium retainers and rev mine to 9000.

i bought the whole rev valvetrain, worth it imo

personally, if i were to do a vtec head for boost, i would just use all oem integra type r parts. those cams seem to do very good under boost.


but honestly, your stock setup will be fine if you keep the revs at stock. there isnt much need to rev it out past 8 or 8200 anyway with a turbo

that is good to know. i didn't plan to rev it past 8k rpm either.

stocks are good but if you want i have a set of ctr valve springs you can have for 50.00
