Sorry about the delay... but no the car doesnt have A/C at the moment. I just picked up SOHC AC bracket/compressor and need to swap pullies.

Exhaust manifold is fine, the turbo flange gasket seems the cause.

Mileage is around 75k. Chassis about 100k +

Car has never been dynoed, so no numbers.
I could care less about if its "just a CA" car was originally being made for sliding but with my schedule i dont have down time. Also could never find a 4.36 vlsd that came in these cars.

I like the fact that i can walk into any Auto parts store and can get crossover parts in stock, 88-89 Pulsar NX SE (ca18de) or 85 200sx (ca18et)
