Recommendations without knowing your goals is worthless.

HP Goal? Streetability? Drag, autocross, road racing? Daily driving? Budget?

Id go with other cams than Type R. My friend put down 75 more horse with Skunk 2 cams at 7 psi less! granted it was at 34 and 41 psi. Most people I know run Arias pistons. I run them at 9:1
What skunk2 cams was he running? What was he running before? Ide like to see that dyno sheet. Why would you go with something other than ITR cams? You can use stock valve train with them and not need to spend 450 more dollars for springs and retainers.

You can run a stock valvetrain with any cams. I don't see the point to this thread.

Youre kidding, right?

I can tell you right now, that I will not run my pro1s with stock valve springs and retainers. If you want to then go for it.

I guess me going to 9500 is a good reason for the upgrade

No I'm not kidding, you may not be able to rev to "9500" safely but you can run them.

LOL! Im well aware of that. I know that my post count, lack of avatar and sig may make me seem like a noob, but that I am not. Ive got numerous dial calipers, dial bore gauges, outside mics, and many other engine building tooks.

Ide assembly his motor for less than 1000 bucks. I can probably supply most of the parts listed about for about a grand.
idk if id trust someone who cant spell to rebuild my engine


haha just fuckin with u man

Have you ever tried them with a turbo application? They work quite well. They are also very easy on valvesprings. They will also still provide a nice power gain without revving to 9500.

I have not personally run them in any of my turbo cars. I know of a handfull of people that Im pretty close with that run Skunk2's Tuner stage 1's in a turbo car.

With such a difference in lift and duration on the pro1s Ide still want the springs in there.

Stock GSR .423"/.380" 230°/216°

Pro1's .500"/469" 255°/255°

Again, like in most of my other cases on here. Ide much rather be safe than sorry.

You can't just look at the duration and lift, you have to look at the ramp rates and closing speeds that the cams will produce. Skunks new amax and fast(whatever) technology is surprisingly easier on springs then most other high lift longer duration cams.

Understandable. Skunk2 says that aftermarket valvesprings are required. Pro springs are recommended. While I dont run Pro springs, I have the tuner springs.

Should we just agree to disagree?

thanks for the input fellas,some good ideas out there...the only bad thing would be to try to get it to pass smog(legit) with all that power..oh well.

pro1s are weaksauce and can run great with STOCK itr springs. i have never seen the point of pro1s

I would run GSR cams if you're sticking with OE.
GSR cams are the best bang for your buck wih turbo and i have seen them make 800+whp ;)
