I'm preparing for a turbo application in the future and want to know if it is worth my time and money to upgrade my valvetrain to handle higher revs?

It's going to be a GSR turbo.

If you do recommend upgrading, what valve springs and retainers?

Thanks for any help...

 

I WOULD SAY JUST DEPENDS ON HOW HIGH U WANT TO REV UP.....I HAVE LS TURBO AND KEPT EVERYTHING STOCK AND REVED UP TO 7200......NOW....MY FRIENDS WITH STOCK GSR TURBO REV A LITTLE HIGHER...UP TO AROUND 8 GRAND OR SO WITH NO PROBLEM...I THINK ULL BE OK WITH STOCK VALVLETRAIN

 

i think that would be dependent on your turbo - when it tops off, and somewhat your cam's powerband.

 

Hmm...I see...so most people stop making power with GSR turboes around 8K?

depends on where your turbo stops making power

there are plenty of gsr's making power way over 8k.

 

that's what I thought........so should I go ahead and upgradethe valvetrain??? I will either be going with a Drag or custom turbo w/hondata.....

Thanks!

 

im not sure what turbo comes with the drag. but i got a t3/to4e and power will start to fall before 8k. so if you getting a turbo like that, i woulnt upgrade valvetrian.

 

I would like to upgrade the valvetrain in my head cause I only rev to 6250 max, but the longer f series rod/ stroke ratio is gonna keep me below 7200 I think anyways.
