Okay I know I brought this up a while back
1986-88 do indeed have lower compression rotors.

Displacement: 1308cc/80ci
Compression Ratio: 9.4:1
Output(hp): 146bhp @ 6500 rpm
Torque: 138lb-ft @ 3500 rpm
Fuel Supply: Electronic Fuel Injection
Engine Specifications (TurboII Model) Engine Type: Twin Rotor 13B Turbocharged
Displacement: 1308cc/80ci
Compression Ratio: 8.5:1
Output(hp): 182bhp @ 6500 rpm
Torque: 183lb-ft @ 3500 rpm
Fuel Supply: Electronic Fuel Injection

1989-91
Engine Specifications (Normally Aspirated) Engine Type: Twin Rotor 13B
Displacement: 1308cc/80ci
Compression Ratio: 9.7:1
Output(hp): 160bhp @ 7000 rpm

My point being.... Would it be ideal to keep the 86-91 intake and swap out for a Turbo Exhaust and turbo, run about 5 PSI for a solid 200 HP engine with plenty of low end torque. The 9.4:1 is a little high for a Turbo motor, but with just a little boost it would seem to be a great performance swap for very little money.
(Also swap out for the 550cc turbo injectors).

It takes a lot of custom work, but it would have alot of power w/ those high compression 89+ rotors. But ofcourse more prone to detention. I was going to do this too, but said screw it i'll just get the whole package.

No I'll do it right. I'm already thinking of a 13B J-Spec Turbo swap next year. I still have things such as paint, seats, airbags (suspension) to work on.
I was only curious about this because everyone seems to think the 86-91 motors are the same internally. I had read of the lower compression and slightly heaver rotors of the 86-88 and thought it would be a great hop up to put a Turbo on it.
I plan to take my Zuki over to a Haltech Tunner to put it on the Dyno and get the HP out of it that it should have. It's too hard to tune and make a run with the g-tech to really be effective.
It's running really good, Starts everytime, pulls hard, but I've gone less than 50 miles and went through a tank of gas.
So I know I am running rich.
