Well it is a A12A. I'm figuring 150 or so horsepower based on what some other SCCA guys have out of them. It will be a few months before I get it together but I want to be sure I have the right one so I can mark it off of the list for now!
This power figure, is that at the flywheel or the road wheel.
Serious racers over here are managing to get about 120hp at the road wheel from dedicated race engines & the trans of choice seems to be a Toyota unit, because they are bulletproof, available & cheap.
The downside is the price of the adapter kit.
The 63 series trans is the one they used behind the L series engines, but with an A series bellhousing so it's plenty tough & if you are going all out racing, it would be the better choice as far as absolute strength goes.
The 63 series trans was never sold in an A series powered car over here, which propells the choice of the Toyota alternative.
If you're running the A12A I presume that you're keeping it under 1300cc for class racing purposes & this is a good choice as the rods in these use the larger 19mm wrist oin which allows you to use the A14 pistons, giving you a wide choice of bore sizes & capacities.
It's unlikely that you will kill the 63 trans with a 1300 engine, but just remember that with strength, & the resulting reliability, comes weight.
