i have an 86, wit a hooped motor and trans, its not mine so i dont know eactly whats wrong with it, but its sitting in my front yard, and its got my name on it if i can find an engine for it, which brings me here for help, basically im looking for the best bang for my buck(most amount of HP with a small amount of budget:P)

 

>>>>86 rx7, gxs?, needing an engine swap badly, and i want to turn it into a drifter basically, couple problems, im 17, i know nothing about rotaries

 

first, welcome to the club. second, give some people a little more time to reply.

third, what kind of budget do you have, and how much experience do you have w/cars in general?

before you go looking for an engine replacement, are you sure it's the motor that's bad? have you tested for compression, spark, fuel, etc?

if you're *sure* it's a bad motor, you should find out what's wrong with it, so you can determine if you just need it to be rebuilt (by yourself or someone else). you can probably find motors at junkyards, but you'll have no idea if they're any good.

give us more info!

 

hey thanks, i found the club after my recent interest in rx7s. As for cars in general, great, havent bothered testing anything because i was imformed a rebuild is pointless(by the owner he blew it, lol) but its the body im interested in i like the look and the drive of the car, even stock, but i dont know what will fit and will be easy or not

 

Well, your easiest bet will be to just put in another 13B, as any other motor will require a bit of modification (more than your budget would allow, I bet, heh).

You should just pull the motor and then pull it apart. There are enough resources linked to on this site to help you accomplish that much. The core itself weighs <200lbs, and comes in 5 main pieces w/2 rotors inside, so don't think of it as being as complex as a piston engine. Once you've got it apart you can find out if it's capable of being rebuilt (the cheapest option).

 

I wouldn't take what the previous owner said to heart. Unless he took the engine apart and saw something that would make a rebuild pointless, there is still a chance you can reuse parts.

j0rd4n is right, do some reading and take that engine apart and see if you can figure out what's wrong with it, and then move from there. The rotary is a different beast yes, but with time and doing your homework you can learn a lot.

 

my budget really has no long term restrictions, with time, and my patience i think i can complete the car i have in mind. As for the engine, i think id prefer a newer one, i plan on doing drivetrain and all, i want to do this properly without making it look too flashy.................but if theres a way to make 250+hp by rebuilding a beat up N/A thats been sitting for about a year and a half now im all for it.

 

Sounds like a standard TII swap is the best bet. It's easy to find the drivetrain from an S4 TII, complete with ECU and harness. Parts lists and instructions are in the FAQ. Bolts right in.

There is, but you probably won't be willing to do it or be happy with the results.

 

yea, i wouldnt think so, so far i think my best bet is an 88, with an import tII, excpet when the engine was put it in, the guy couldnt get it to start, and he ran out of time to work on it, does anyone know what it might be
