I have recently finished purchasing all my parts for my turbo build finally, but nothing for the head. would it be necessary for a set of springs, retainers, valves, and valve guides, or should i stick with stock ITR. my hp goal is anywhere between 350 and 400 whp. any advice would be great on this or anything else. thanks

 

how high do you plan on revving it? stock retainers tend to crack on higher revving motors from what i hear, i would upgrade its called insurance lol i just put supertech spring and ti retainers in mine and have revved to 9500 with no issues yet

i just looked at it this way, you investing all this money in the motor right? dont go cheap, upgrade everything that usually goes wrong...

 

yes i agree but, oem is good quallity and i have read that itr valves are good to use and didn't know if i should use aftermarket springs and retainers.

 

ohh and i didn't paln on reving past 8500 but i guess i could with aftermarket springs and retainers.

 

yeah, use the stock itr valves and just upgrade the springs and retainers

i took my stock gsr valve train to 9200 lol for almost a year with no issues, some people get lucky and never float or drop a valve and some dont

 

do you think stock itr valves can handle double hp and high revs reliably?

 

oh yea, i still have stock gsr valves in my motor and its pushing over 400whp

 

great thanks that is all i needed to hear.

 

no prob man

just get some springs and retainers and you will be ready to rock and roll
