I said on a stock motor, not a stock setup. You can reach 400whp on a stock block, internals, head, cams 4g63t motor easily. Anotherwords there is no need to do a "nasty mutant hybrid" when you can do your goals on a STOCK MOTOR.
You will want a rebuild trans with atleast a double sinc. 2nd if you want to put down real horsepower.
Will the tranny be match up to a 4g63 or a different type of 4cylinder.
