i think the truck weighs about 2600kgs. if i put a turbo on the stock engine i could make just as much power as the sr but my engine is shot and i want a six cylinder and the rb25 would be perfect im ordering the engine soon im waiting to hear from japan if i could get a something with about 600whp. i got a little 75shot zex im wondering what would be the best setup if i use the nos.
