What's stage Comp Cams will suit a 2.2 and Harrop setup?

Website suggests Stage 3 for Harrop, but turned off a bit about it putting power at the top end.

 

 

Supercharged: 
-The Stage 1 cams are recommended for most supercharged builds, these cams will raise your powerband about 500rpm.
 

-The Stage 2 cams are the next step, they will raise your powerband about 700-1000rpm, they will make peak power around 7500-7800rpm!  They will require an ATI balancer to help reduce engine vibrations at the new high RPMs.
 

-The Stage 3 cams are recommended for all out race cars, not intended for street cars due to their high rpm powerband. 

They were designed for our all out drag car with the 2.4L stroker engine.  These are the cams that Turbo Tim runs in his 400whp, stock blower, 2.4L stroked Saturn Redline that makes peak power at 8500rpm.  So on a 2.0L they should make peak power at 9500+rpm which would require a highly modified valvetrain to support.

 

ZZP S1 is 210/206 @ 1mm and 10.78mm/10.69mm lift, 109 LSA
ZZP S2 is 216/218 @ 1mm and 10.78mm/10.69mm lift, 111 LSA
ZZP S3 is 216/224 @ 1mm and 10.78mm/11.10mm lift, 113 LSA

Stage 3 is better suited for TVS setups running more boost than M62 cars or S3 would also work well on M62/nitrous applications.

Those quotes are for the Saab/LSJ 2.0 displacement. A 2,2 can/needs a bit hotter cams, so that stage 2 cam on a 2,2 acts a bit like the stage 1. (Forget that Stage 3 as it's a race cam.)

Could you confirm what we would need to get for our stage4 harrop builds. Super tech vale spring set 78lbs http://shop.zzperfor...Spring-Kit.aspx Injectors do we need (EV6 or EV1)? http://shop.zzperfor...njectors-4.aspx Blower cams (Are these correct and what stage)? http://shop.zzperfor...mance-Cams.aspx Valves? I've found these but they look a little OTT. Is there other options? http://www.allecotec...products_id=120 What else do we want from the US or is that it? Thanks kind sir.

Ev1 injectors are what we need.

Harrop "Stage 4" ??

 

- Supertechs or other decent springs for higher revs

- a good flowing head (exh porting will do, preferably sandcast Saab version with the saab valves)

- Siemens 60lb inj, EV1 (= Bosch connector)

- ZZP or Comp "stage 2"  blower cams if you want max rpm power

 

Together with a decent bottom end (we use the std forged Saab 2.0 components) and did I mention VERY GOOD charge coolling??

 

Owww, a working ecu/mapping will be nice to keep it all in one piece.
