i want to get get new valve train for my gsr so i can take it higher and was wondering if i would be fine with buying itr valve train or some after market brand?? i heard with itr vavke train i can pretty much go as high as i want?? thanks for the help.... i have itr cams and am going to be boosting around ten maybe more in the future

 

I went with the supertech valvetrain and rev mines up to 9500rpm.

 

I dont think you want to go with ITR valve train.
The ITR valve stems are thinner and lighter than B16 or B18c1.
Becouse of that Im pretty shure the valvesprings are a bit softer,reduced valve weight will give the springs more control to reduce chances of valvefloat, softer springs will also reduce wear to the rockerarms.
(sorry about the word spelling, Im from Norway)

With boost you usally want to go with stronger valves, and stiffer springs.

-Supertech or ferrea package would be my choice.
at laskey racing I believe S-T go for 525USD

 

huh i didnt kno that about itr valve train. ya i was jus trying to think of a cheaper way i could build my head.

 

need a bump

 

i would definately opt for the supertechs over the ITR valves, and really they arent all that expensive too. 525 packaged with springs/retainers.

 

 

do you have to do a valve job when you install new valves? what is a good ballpark estimate for that?

 

yes a valve job would be required on new valves, ITR or supertech just the same. give a call to some local machine shops for pricing.

ya but to get a set of itrs wud be cheaper than an after market brand. and ive heard that itr valve train will do the job?

 

i would just keep the gsr valves in there VS the ITR valves if you are looking to save a buck. the ITR valves are made to be lighter not necessarily stronger.

 

i have a b16 head with my ls-vtec. the head is all itr and i can only take it to 8300.

 

ya and gsr's r good to that about to

 

ferrerea 9200rpm great choice and strong

 

how far can u go with the supertech?

 

hit 9k with mine...... might wanna try crower valvetrain but thats pretty pricey.....
