2.2L Stroker : Camshaft to revving 9000RPM
Hello,
What kind of camshaft for revving 9000 with a 2.2L 4g63 stroker (94mm K1 billet crank, 150mm Oliver billet rods, JE asym pistons, +1mm exhaust/inkate valves, ATP GTX3582R ) ?
GSC R2 can works to this rev?
Any suggestion?
Thanks

The R2 is just as extreme as the S3. R2 has about .3mm more lift, and duration at 1mm is only 2* shorter. I would put S3's in if you to rev it to 9k. R2 is prescribed for 4000-8500 on strokers...

If you are looking for suggestions other than gsc r2/s3 (which are great choices) then your other choices would be tomei procam 270 or 280, and buschur bf272s. All of the above did really well on the dsport cam comparison test. And they all have a VE profile that matches well with a 2.2 and its expected power range.

7000 series are the new camshafts. I don't think there are any differences but now being billet. I'm sure someone will add info if there are other differences.

0 to 8500rpm - R2 will have the broader more torquer powerband good for light to light and scaring passengers
8,500 rpm to 9500rpm and up - S3 will have a slight advantage over the R2 giving you a little more top end, but it's a seesaw effect, what's given up top is taken from down low and vise versa.
R2 = Street fun and gets through traffic quick - stroker
S3 = Race fun, highway pulls and track runs - does work in Either, but best in high rev engines like the 2.0
6008R2 - cast camshaft and discontinued
7008R2 - Billet camshaft and current superstar!

I have two choices :
1- 2.2L stroker like above
2- 2.1L long rod stroker kit Magnus (92mm crank and 156mm rod)
The rest of setup (turbo and head) is the same.
Any suggestions? I cannot decide about these setups.
I like to run revving high but without sacrifice low/mid as possible obviously.
So...2.2L with R2 or 2.1LR with S3 ?

Keep what you have, and put S3's in it.
