Whats the next step for more BHp!
Hi people, just asking around for advice on the next step to wring some more power out of my S2 ERST. I have had the engine fully rebuilt and a fully recone stage one turbo unit fitted. When i had it set up it made just under 150bhp on the rollers, although it gos like a scolded cat i now need more. What would be the next mod? cam, chip ect??? any advice would be appreciated.

First thing to do mate is get some better brakes ! No point in giving the car more power if it can't stop ! As far as tuning goes, a chip and actuator is the first thing. That'll see 180 and will transform the car. Depending on your budget then a K&N, better flowing exhaust and either a larger intercooler or a chargecooler (all in that order). If you did fit that little lot and had the car set up properly you're then over 200 horses - easily.
But, alas, then you need to bear in mind that an uprated clutch will be on the shopping list
along with tyres, possible gearbox rebuild............... 
Bit of advice - don't be so concerned with 'what bhp will I get'. That's pub talk bullshit and in 99% of cases only any good for saying to your mates 'my cars got more bhp than you - 'innit.........' torque is what makes the car more driveable and quicker in the real world

Rick, thats 20bhp up a standard engine? I was under the impression a good std engine will give you. . . 132bhp? maybe 5bhp more give or take. . but 20hp more?
I'd go for:
mongoose/magnex exhaust (scorpions have been proven to be restrictive although some cant/wont believe it) chip (MSD/NMS etc) -31 actuator, modified standard airbox with K&N panel filter (cut the front off where the small circular hole is) cone filters suck in too much hot air believe it or not. cam. . newmans. . and a FMIC (GRS/PRO Alloy) coupled with your stg1 turbo and a good setup you should be producing some good power their

Not going to attempt to give any advice because i have no idea, just curious about clutches? 180 - 210 bhp. what sort of clutches are avalible. as i dont want a track style on/off clutch but obviously standard clutch couldn't handle the torque going through it. so what options are there?

Maybe you'd make more power with a less-restrictive exhaust? (assuming you have the old one)
older scorpions DO have a restrictive backbox, Ive heard the new ones dont, but then ive heard people saying the old ones aint restrictive!!
The proof is in the pudding

Not a very scientific picture you'll agree, but it does give you an idea.
std system 2.5" from turbo - tailpipe
scorpion system - 2.5" from turbo - backbox where it goes into 2" inside the box then to whatever size of tailpipe you have.
mongoose - 2.5" from turbo -backbox-to whatever size your tailpipe is.
go check, like I say I cant speak for "new" scorpions as ive never saw one!!
