so i own a 92 nissan 240sx fastback. my stock 4banger's piston rings are shot, and im burning a quart of oil a week. looking through my options i have they all seem very weak for the amount of money they require to get. used 4 cylinders from overseas aren't worth the bucks. so talking with my brother-in-law(who's pretty heavy into domestics) he started me on the idea of an aluminum 302. i just have a few questions...
1. how much would this engine weigh? my stock engine+tranny weigh around 500lbs, its pretty important that i keep the weight down so i can keep my near 50/50 weight balance, and thus keep the great handling of my RWD sport compact
2. Transmission... it seems like a pretty normal thing for your power houses to have an automatic transmission, nothing bad about it but i want a manual, i like having more control over the car considering i autox and drift more than drag. what should i use? i dont need a super-racing transmission a stock one would be fine, especially if its 6-speed
3. If i do this im going to go with a setup similar to this
http://www.mustangandfords.com/tech...8898/index.html, i currently dont have an engine to rebuild. what would i tear a donor engine out of in the junkyard?
4. Also, what kind of gas mileage would I be getting with this engine? Right now i'm getting about 17mpg.
thanks for your time and help!
