Im currently running a b20vtec N/A w/ around 11:2 - 11:3:1 compression. I recently just got it tuned on the set up below, but maxed out my prelude 290cc injectors at 6k. I just bought some RC 550cc injectors and need help on deciding if skunk2 stage2 would suite me better or Will Skunk2 pro1's be over kill for my compression. i also purchased skunk2 proseries dual valve springs and ti retainers!

I would consider the Pro2+'s, actually.

They work great on my 11.7:1 LSVTEC, and I expect they would work just as well in your two-liter engine.

yea i've read the how 5pgs on it but doesnt really help on what kinda compression is ideal for pro1's...i know i can run s2s2 no prob but if i can run pro1's w/ my compression imma go for it. thats the answer im looking for?

 

same cam really can't go wrong either way.

 

i dont think there is enuff compression for pro2s stick with the stage 2

 

enough compression for pro1's tho?

 

pro 1 or 2 should be fine imo

im leaning more to pro'1 but no one has deals on them....i found some skunk2 stage2's for $350shipped

 

...

 

any one of those will do but id run pro 2s if i were you. check your retainer to valve seal clearance and check your V2V. you should need to run your exaust cam 4 degrees advanced to get minimum V2V clearance.

yea i plan on claying the motor for clearance if i go w/ pro1's

 

pro2's just seem like it'll over cam my motor since the motor is only around 11:3:1

From the link above, the stage 2's made around the same amount of torque as the pro1's and pro2's the whp wise wasn't that big of a difference..take into consideration what's done, what head, and whats the setup as awhole.. i think your best bet is which ever u can afford they are both a great cam..

I thought skunk 2 recommened 11+ compression for pro series cams. I'm have stage twos in my 85x89 build and there awesome but I sure would like to see how pro2s do. Good luck

 

***** it! im goin pro1's! ordering them tomorrow

 

i think that is a good choice

 

dude nice choice. Where are you ordering it from if you dont mind me asking?

 

pm'd!

 

good choice, especially if you like power below 5500. the larger primaries of the pro series dominate down low....

 

im pretty sure 440cc would be good.... good luck on the build dude

 

I only experienced pro 1's and pro 2's. I can't say much about stage 2's so I'm sticking with pro 1's/pro 2's.

 

yea im goin to keep you guys posted on the build and dyno numbers!
