Planning on slapping an itr cluster in my rex and getting it boosted in a couple months.. but if I got let's say the skunk2 springs/ret/valves would I be able to redline at 8400 on like oh.. ~16 psi?

 

I would think so, what engine?

 

b16a1...

 

don't b16a have a 8500 redline already?

 

Just go with ITR V.Springs, and you'll be perfectly fine.

Even when I'm boosted with over 10psi?

 

boost has nothing to do with rotation, just do as he said get typer valvetrain and youll be all set, well after you remove the revlimiter

 

Coool well that saves me some cashola.. rev limiter psh I'll take care of that in no time.. thanks!

 

IMO you got nothin' to be worried about revving a B16 to 8500.

 

skip shifted a stock b16 with a bad tranny to 9,800 w/o problems. Wouldn't recommend doing that, but revs will not be your prob. Just make sure everything is to spec. and you have a good timing belt. Before deciding on turbo, I was building a poormans itr for a 12k redline. Just build up the bottom end and replace your springs.

 

i dont see the need to rev to 8500 if your boosting 10 psi..but thats just me

 

It wasn't a NEED really I just wanted to see if it was any different than n/a

 

rev as high as you can as long as your still "making" power and within a safe range. The idea with a turbo is to be able to stay in a gear, hence why I'm holding on to my old LS tranny.

 

Hehe when lookin at cams for turbo.. what is recomended? I mean Aem adjustables aren't gonna have the same effect for n/a as to turbo..?

 

just decide how much power you want and how much money you want to spend. Of course Turbo cams are going to beat out adjustable gears.

 

Yeah.. I want some go000d power but nothing like hp coming out of my ears kinda stuff.. My buddy told me crower cams were one of the best.. I think I fall under between mild/lots of horsepower.

 

ya.....i did springs retainers and ran mine to 8700 or so....now the bottom end is rebuilt i go to 9000...not with stock cams of course...

 

Would itr valves be good too or should I get some 'better' ones?

ITR valve springs and retainers and you should be fine for 8500rpm. A stock ITR redlines at 8400rpm!

If he's still making power up ther why wouldnt he rev that high??? By the way check out ef-1 springs and retainers.........very cheap and the highest quality you will find

 

Don't get type-r retainers, they are the same as B16 retainers. R springs and some Ti retainers and u can do 8.5k rpm passes no problem. I have Portflow inner and ITR outer springs with S2 retainers and I have run at the track shifting at 8.5k rpm and all is fine, my compression actually went up since I put it all together.

Portflow is cool and all but you can get EF-1 springs and retainers for the same price that you could get portflow springs.........They are proven just go with them and you will have no worries down the line to even higher RPMS. Contact Rocket about them (EF-1 I mean)

 

Well okay I just got itr springs.. I'll get the ef1 retainers but what about the valves?

 

Your valves can take 8.5k rpm no problem. Valves are not a drop in kind of installation, if u drop brand new valves in a used head they will not seal as well as the original valves and u will lose static compression and lose power. Also just dropping new valves inside used valve guide’s is not a good idea either, there is a certain amount of clearance there should be between the guide and the valve. Too much or not enough clearance may bring very nasty consequences.

 

Well I was told my valves need some work anyway so I was thinkin to do this all at once..
