my old A15 i had in my coupe (Muke now owns it) it could beat VP commys, the work I had sone was overbore to 79mm (making it a little over 1600cc), I used TX3 pistons (flat top's),
shaved and match ported head, twin 40mm webbers, huge cam (never quite knew the specs of it)
4-1 extractors and a 2" mandrel bent exhaust.

Tranny was a Celica 5 speed.


So yeah you could beat him with a done up engine, but in the long run force feeding it may prove cheeper.
