Pick 'N' Pull, the KA24de is a very stout engine, it was first designed for the Nissan Pick-up and was used, here in North America, in the S chassis, cause the American public prefers low end torque over high end power.
You can get the engine from earlier model nissan Pick-ups and Pathfinders and first gen. Altimas. except the Altima is FWD obviously. The good thing is, they are next to free, since everybody drops them for the SR or RB or VQ or even VH now...
The frame rails, right where they curve up along the base of the fire wall, especially on the exhaust side. Due to a poor design, the cat. being too close to the chassis, the heat cycles that the sheet metal endures, speed up corrosion 10 folds.
Also the shock towers are prone to heavy corrosion and the rear dog legs.
Avoid HICAS, too complicated device to survive trough 20+ years of day to day abuse.
Also, the 89 model came with a LONG nose R200,
89-90 had a 12Valve engine, later ones had a 16Valve.
If you're tall, avoide car with sun roof.
I sure hope so LOL. It's the stock engine for the car everywhere else in the world. I think they in fact designed the car and the engine together.
