Buying 1994 white rx7 [serious help!!]
trans is automatic (broken)
engine is most likely also broken
Before i buy it, i want to find out HOW HARD is it convert Automatic trans to manual? did anyone do this before? (if you did how much did it cost you? was it very difficult?)
i have always wanted an rx7, (todays my bday so my parents bought me a 2001 audi 1.8T stick (daily driver) and they want to buy me this rx7 for street and autox use.) i thought this was a good deal, because i found both engine (13b-tt) and trans (manual) for 1800 bucks.
I would really appreciate it if someone could find out which parts i need to make this conversion work.
Im no new guy off the street... i have been taking courses for automiotive i can handle a job like this. The thing that scares me is that its rotary, i get the basic of rotary, i have rebuild piston engines before... by buddys 2003 evo8 stun a a cylinder bearing so he decided to stroke it to a 2.3L i was thr 98% of the time helping him out. But rotary is a def different, easier to rebuild, but break more often.
I was also wondering if i could add a 3rd "cylinder" to my 2cyl rotary engine, i have heard this being done before, idk if its po$$ible for me to try it. are the power gains worht the money? can it be done in a garage?

heres some quotes from teh FAQ they should help some.

It is not a bolt-in swap. 3 rotor engines were produced by Mazda for the Mazda Cosmo luxury car. It’s called the 20b because it has 2.0L total displacement and it was never sold in the US. The engines are imported and installed in an FD with significant work, including modification to the firewall or a custom engine subframe. Many systems require modification, and much of the installation and tuning is manual labor. The simple fact is a 3-rotor motor is not expensive by itself, but the installation and tuning is. 3-rotor FDs require a budget exceeding $35k, not including the car. The good news is that a 3-rotor creates significantly more torque and horsepower than a 2 rotor. If you’re serious, and have the funding and time, start here.

if you want more power you would proberbly be better off modding the 13b engine. they can make really good power -- another cylinder is not really needed.
If you really need another rota you will need to put a 20b engine in it, which is no easy or cheap task..
you should deffinitly get the car up and running and see how you like the 13b before you even consider anything like a 20b swap..my 2 cents

Converting Auto 2 Manual is not worth it IMO, i think it will be easier for you to shop around a bit more and find a rx7 closer to your desire. (unless of course the one your thinkin about buyin is dirt cheap)

DDDDDDDi know the owner (if i buy it ill be 2nd owner) so i new how he took care of the car, before the winter starter... around nov... i drove the car and it was perfectly fine

yeah man... I thought about it... even if i need to get a new engine... ITS STILL WORTH IT!
the guys says its an easy fix (+/- 500 bucks)
i know him for 11 years now. he wouldnt lie to me... lol i know where he lives
but im just prepared for the worst of the worst... new engine/tranny/erethangg.
but imagine this 1000 for the manual tranny swap den 500 fix of the engine. 5,000 dollar car that is impossible to find now. They made 89 of these in 94.
but ill mod it... full exhaust, intakes, clutch flywheel to start off
then intercooler, injectors, spark plugs, intake elbow & other stuff i cant remember now.

You should get a mechanic or a friend with rotary knowledge to scan the car. But you better learn more about rotary before you throw all the money in and screw the car up.

the PO probably beat the hell out of it.
That said, 94GTrx7, I assume yo're about 16 or 17 years old. I'd suggest you avoid getting a 7 until you can affortd to buy your own cars, not take your parents hand me downs.
The car will be expencive to rebuild, expencive to maintain, and trust me when I say, the less you buy the FD for, the more money you'll waste on getting it up to par.

the key word is LEARN. read the faqs until you wake up at night repeating parts of them, THEN worry about modding the **** out of the car.
check the regional forums on here for your area; chi-town has a fairly healthy rotorhead population, and most guys are really decent about helping a fellow rex addict out.
as far as the 20b engine, wait until you max the 13b. you'll be very pleasantly surprised.
it sounds like you're mature enough to respect the car and not **** it and yourself over. just out of curiosity, what bday is this?
AND....you have some damn nice parents.
