BOB is a slightly more powerful unit but to run it on the cheap will mean a BOA ecu and harness which again will only achieve at best, 220bhp There are some that have had slightly more from these basic mods but in reality this is all you can hope for.

Ecu upgrade will definitely see more gains and with some decent manifolds will see around 240ish......... After that there is the option of throttle bodies but now we are well into the thousands ££££££ There are a few 24v's with throttles and I suppose with the right management they could probably get to around 300bhp at a push??? but don't quote me on that.

Finally there is boost Now this will cost at least 2k if doing yourself and that includes making ya own manifolds and sourcing s/h parts to keep costs down or if you pay someone to do it, easily 5-6k I would say. Now this will get you well over 300bhp and the grin factor is what the doctor ordered. Not cheap but very individual and the noise of a boosted V6 is fantastic. I opted for turbo on mine as it was never fast enough as a N/A and tbh, apart from breaking gearboxes and driveshaft's its the best thing I ever did I'd say I ploughed 3k into mine with the right bits and doing all the work myself to get it where it is now but its a choice I took to do it correct. Its not everyone's cup of tea as the engine does have its restrictions with a poor top end rev range and its an old design and a tad heavy but again this can be overcome with some more mods deeper pockets......

If you have the basics already, engine, harness and gearbox...... Stick it in then see what you think. You will get a grin factor straight away coming from a 2.0 twinky to this.
