Looking for a good website to buy a cheap motor for a 91 RX-7 ROTTARY engine?

Question

Im willing to buy brand new as well, I wanna keep the car.

Answer 1

You can have a Mazda dealership rebuild or order you a new engine, or you can buy a rebuild kit for a rotary engine for about $1,300 at http://www.racingbeat.com/FRmazda2.htm

RacingBeat makes high quality RX-7 parts and is a trusted source. The kit isn't that bad, but you'll need to get estimates on labor, and that could cost you $3-5k.

Find a local garage with RX-7 and rotary experience and you'll save a good 25% from what a dealer would charge you.

Fwiw, I had a new turbo and rotary engine installed and it cost me about $6k at the dealership. You have to really love the car to put that kind of money into it.

Also, more and more people are putting small block Chevy V8 crate motors into old RX-7s now - the balance and weight is about the same, but the engine is more reliable and a bit more powerful.

and search for 'v8rx7'

Answer 2

I would recommend having a rebuild done and not trying to source a used motor. If you get a used motor, you are likely to need a rebuild on it anyway. Sourcing a brand new engine is very difficult and very costly. One of the best rebuiders around is Rob Golden at Pineapple Racing. He is well-known throughout the rotary community and people from all over the country are running his engines. I am lucky enough to live close by, as he is in Portland, OR. Check out there website at www.pineappleracing.com and give them a call. It would be worth spending the shipping money to have the motor rebuilt by him. He stands by his warranties as well.

hi to UpState long island From way Down South... those autos are super and exciting tocontinual, yet once you will desire to ask at here in case you will desire to purchase one, i might say do no longer... With the emissions the federal govt. made Mazda positioned on the Rotary Engine it particularly is fairly perplexing for a DIY to maintain in the event that they don't have an intensive historical past in mechanics. That mentioned maximum suitable notch Mechanics/Techicians available who're Piston engine experienced can't replace there attitude while engaged on a Rotary engines. Piston & Rotary Engines only share being inner combustion engines mutually, different than that they have no longer something in uncomplicated, so which you may't restoration the comparable situation the comparable way. areas for those are particularly no vast deal however. maximum after marketplace areas domicile can furnish maximum folk of them and for those that they are in a position to't google RX 7 and notice what you arise with.... I actual have owned many 1st (seventy 9-80 5) & 2d (86-ninety two) era RX 7's and enjoyed each physique...at present have a 1985 Base Mdl interior thecontinual, a 1984 GSL-SE, 2 1st gen areas autos and the 1st Gen My Brother grow to be driving the evening he died...I even have various fix manuals & MicroFiche on those autos... finding forward to procuring a third Gen sometime and function plans to construct a three-rotor B2200 Sleeper...

Answer 4

finding a motor for your rx-7 will be extremely hard, finding it cheap will be even harder. E-bay is cheap but risky, try to find someone on ebay that is relatively close to you so u can see the engine. Usually the cheaper the engine, the crappier the engine will be. You can also search through rx-7 clubs that are near you.. they may have some information that might be useful in finding your engine.

Answer 5

I worked at a Mazda shop for 4 years and we mainly worked on RX-7's. The later 13B Mazda Rotary from second generation RX-7's don't last very long because they had small apex seals. (to save friction (gas) and make a bit more horsepower.) They usually last about 85k to 120K miles. Finding a used American market motor with low miles is very hard these days. Most of them will likely be on their last leg.

I would suggest one of three things: 1) Buying a Japanese market motor (because complicated Japanese laws make it very hard, and expensive, to drive cars for very many years) These motors ussually have about 50K miles on them, though it is hard to know exactly what the have. Search for "13B JDM".
2) Buying a factory rebuilt motor from Mazda. I installed a couple of these motors a few years ago. They cost about $2000 in 1997 and may be a lot more today. I'm not sure.
3) Have your motor rebuilt by a shop specializing in Mazda Rotary engines. The Mazda Rotary engine is moderately cheap to rebuild but requires an experienced builder as it is VERY differant from a piston engine. My race car has a Mazda Rotary built by http://www.iscracing.net. Mike builds great engines and mine cost about $1,700. For a bit more he can convert a second generation engine (like yours) to the earlier, and more durable, thicker apex seals. You could get almost 200K miles from one of them as per the 84-85 GSL-SE motors. I'm not trying to do any advertising here. It's just I have experiance with ISC motors. There are lots of other good Mazda Rotary engine builders. Just make sure they specialize in Mazda Rotary engines. "And that's all I have to say about that."


Great Luck

Answer 6

Cheap + rotary = not in the auto dictionary... so sorry. I know.. I'm panicking about the day mine dies too... and I'm hoping that magic little word 'warranty' will still exist in my vocabulary..

Renesis rotary is up to $14000 CDN, new.
Get a rebuild kit, get someone to rebuild it for you. You dont want a used one... unless you want to rebuild that too. I am told the rebuild kit starts at $1500 (dont know for sure) and countless hrs of labor... but its damn better than getting a loan for an engine thats worth the price of a new base little car of some other nature.

Good luck!

Answer 7

Answer 8

Trying to find a good used motor is tough. If you blew up your old rottary engine, cuz knowing the old owners, thye rodded the sh!t out if just like you did. you might want to get somethine else thats cheaper to fix.

Answer 9

RotaryResurrection.com is the best "cheap" rebuilder in the counrty. You'll have to ship your engine to Tennesse though.

Answer 10

cheap and rottary don't mix! sorry to say that, but that engine isn't cheap and for good reasons! it's good you want to keep the car, but you are proably going to have to get a new engine.
