200 at the tyres would be a full house mean mother of an A14, perhaps in the upper limits of the power capabillties.

I just remapped the ecu on mine the other day with a bit more of a road tune, more aggressive timing map. althoug kept at about 10-11 psi. As a result of the power increase I have today just destroyed a gearbox( 3rd gear has no teeth left) It was in gear accelleration, with very gentle changes. 56A box. I fortunately had a spare, although that little experience tells me I need something alot tougher.

got to love a gearbox you can hold in one hand though.
