Yeah, the Z20LET 2litre 16v is the engine used in the coupe turbo and the gsi, regal or courtenay will charge you £400-£500 for a phase 1 upgrade giving around 240bhp. it is more expensive to mod than the LCR, u'd be looking at the best part of 2k to get around 270bhp, the vxr turbo also seems to be a popular mod now
That sounds cheap to me - AFAIK a £500 remap will give you 220bhp (Stage 1), you need a new exhaust for 240bhp (Stage 2) - Milltek seem to be the preferred option, and a Milltek plus remap is around £2k (That's what I'm thinking about for the VX)
You need charge coolers etc. I think to get to 270...... (Stage 3) then you can just go silly with Stages 4 and 5 for 300hp+
This is all according to Thorney Motorsport anyway, which, IMO, are the guys in the know when it comes to Vauxhall tuning....
