ive got a 2.0 8v (seh) engine. at the moment it has k&n filter with cold air feed from front bumper, superchipped ecu, kent fast road cam.

what sort of power do u reckon this should be putting out?

im looking at probably a 4-2-1 manifold then eventually stainless system (power gains??)

also what other cost efficient mods would you suggest?

thnks in advance

The superchip won't be doing you any favours if you've got other mods as well as it won't be designed to work with them properly.

yeh i wos thinkin of just geting a standard ecu, run it on both and see which feels better to be honest, can pick up an ecu for this engine for very cheap u think it would be worthwhile?

I had an SRI 130 that I blew the engine on so i rebuilt it, new rings honed bores, crank grind etc and while it was in there I had the head ported and flowed with 3 angle valve seats etc. 4-2-1 manifold on when I rebuilt it and a Cone filter with a cold air feed, also put a FSE boost valve on, these dont give any more power but they do help throttle response quite a bit.
I had that dyno'd at 142 bhp with torque peak slightly up on an XE ( but obviously for a shorter period of the rev range) What an excellent motor that was. Upto about 100mph I could stick with 16v astra's, after that they pulled away, the 8v dosnt like being revved. Excellent back road tool tho.
