Whats your budget?

I think a Renesis engine out of an RX8 would be the best engine but that will get you 230+HP N/A

Getting 200HP N/A out of a 13B block can be done with some porting work but be prepared for a pretty loud car.

I know of a guy in California that is doing a Rotary swap into a 914 I want to say he was using a 3 rotor n/a rotary.

Don't eliminate using a stock turbo 13BT engine. They come from the factory with 200HP and can bee tweeked just a tiny bit and you'll have an easy 200 to the wheels and way more torque. Food for thought.

I should be doing some little road trips next week breaking in my engine I'll see about a across the state one and we can discuss this over lunch one day.
