posting for a friend who was after building his engine upto 450 bhp, which is starting to cost a lot of cash

so he is now thinking of just buying a bigger engine already done and save all the messing about

so what would a stage 3 2wd cossie engine be worth ?

The engine ran bayoo stage 3 chip, greens, 3bar and hybrid turbo at 20psi and it really well before it was striped it do the work, it has approx 90 k miles on it, it was rolling roaded in august at well lane which he has a graph for, its been seviced well all its life and had a full engine rebuiled about 20k ago by its former owner who can be contacted on here if needed.

we are just thinking it may be cheaper to get a new head gasket set build it back up and sell that to fund a bigger engine

he has also got a p8 ecu mapped by paul hills for an 8 greens low comp wrc inlet and t34, als etc,etc and a full motorsports braided pectel loom

so what they worth and is anybody interested ?
