These are some of the engines up for grabs on the VR6 forum......
1. Obd2 2.8 vr6 engine, cammed, Vortech V2 charger and united motorsports ecu running 280-300 bHP 155k @ £2,200
2. Obd1 2.8 vr6 engine c/w T3/4 turbo, short runner, intercooler, pipework and storm developments ecu running 350-400 BHP 135k @£2500
3. Obd1 2.9 corrado vr6 engine 145k £200
I think the Raddo engine would be a good choice as they are 190bhp standard and almost all of them when RR'd produce 195-200bhp. Only thing is though all Raddo VR6 engines were OBD1's so dont know how the wiring/engine management would be on your 8v GTI?
