dont fit NOS in a corona.The corona is a heavy car. Since diesels have low-end torque, its best u use a light car if u want a diesel engine. Fit the 2200 3C-TE in an 83, put in NOS in that, and u can beat a modified civic! a 3C-TE in an 86 without NOS can beat a 96 corolla with a 4A-GE Four-Throttle engine, this happened to someone i know in karachi! i have a corona too, in which i have installed a 3C-E, but the car is heavy so the initial pick-up is slow.
3C-TE=2200 cc Turbo EFI
3C-E=2200 cc EFI
both these are extremely efficient engines.
