So I'm going round and round trying to find a low bucks close ratio gearbox solution (there isn't one) I started to think back to the reason Harry stated as part of why he went to the L series motor. One of was availability of decent gearboxes. The other obviously is mid range.

The current A15 motor is putting out around 105whp and I could tune it harder without going to crazy (keeping mind full race A15 is 150) but as with each notch up the motor becomes pesky. When my A12 went from 73whp to 80whp it no longer did anything below 4500 RPMs.

So the thought is a 120whp L18 is not tuned that heavily versus 175 for full race engine. This could be tied to a 280ZX gearbox and would only add about 60-80lbs to the car.

The other bonus is the vintage racing class I run allows me up to 2.0. Because the LB110 ran L series I can get away with it in the 1200.

So thoughts?
