engine of choice
The engine of my 85 rx7 is busted.....that means time for a new engine yippeeeee!!!
I wanted to know which engine is able to FIT and best performance for my car. I'd like to have my car running for a much longer time so I've decided I would install my car with a new engine, but not fixed up. I wanted to know what engine would be best for the rx7, an engine from a 94 rx7 or maybe 92? I don't know much about cars, so I NEED HELP!!!!! any information would be most helpful

hmmm... man I wish I can give you some advice but I heard the TII Engines are nice. Beside that not sure what would be best engine for you. I guess it all come down to a personal pref. However there are good experts in here that would help you better. I am still trying to figure out what would be a very good engine for me too and upgrade. Looking for 200HP or 300HP most I guess I will have to search around for info.
Good luck on your decition.

I would suggest a 4-port 13B. Parts are plentiful, usually less $$$ too. Easy to work on/rebuild. Street port the 4-port and a decent carb/exhaust setup you would be at 200-225 HP at the flywheel. The thing would last forever, as long as you maintain it, the same goes for anything though!

Since you don't know much about cars and want something that will last, it's hard to beat a 12a for simplicity and longevity. They are a little short on power when compared to the REW's, but you pay for that extra power with higher purchase price, higher parts price, and higher maintinence. It is also not an easy swap.
You didn't say what engine you have in the car now, but both the 12a and 13b can be built for more performance and hp.

I really like my "street-ported" 12A.
225 rwhp,
idles at 400 RPM with a Weber 48 IDA... Pulls with power beyond 9K.
would make an awesome daily driver if it could get better fuel economy.
If you want to go the 4-port 13B route...
I have an old 4-port crate engine. it has been used maybe 8K with a proper break-in. this is the engine that would have came in the 74-75 Repu and RX-4. (big exhaust port).
I have it available for $1000 plus shipping. I have a Weber 45DCOE set-up jetted and ready to go.... and an RB Header to help complete the swap... if interested, send me a PM.

stop trying to be an E-thug. Instead of accusing him of lying, why don't you ask how he got those results?
And while you're at it, why don't you ask him about the TII engine he built for a guy named Mike in Indy that idles at 150 RPM...

No, it is not stock!

Transportation or Hobby?
If are not an experienced gearhead, you should be looking for reliability. the advice of staying with a 4 port is good advice, either 12a or 13b. You would have to modify the front motor mount for a 13b because it is a bit longer. I took a 12a, street ported the secondary intake ports(using the RB template), cleaned up the primaries and the exhaust. I made an adapter for the manifold and installed a stock RX-4 carb, RB exhaust header. It makes 130Hp to the rear wheels, which is all you need for a fun daily driver. A completely stock 4 port 13b with the same exhaust will give similar performance.
Don't let people talk you into an aftermarket intake system and carb, Webers, Holley or whatever unless you are looking for a new hobby. The stock carbs run well hot or cold and will avoid a lot of hassles for you. And you definitely don't need a turbo.

All "clean85owner" is asking is for a dyno! Fair enough. Too many unsubstantiated claims on these forums.
I too would like to see a dyno as if this is so it must be the highest HP NA streetport there is bar none.
Oh, and "Another Driver" I would build a nice 12a Streetport.

Just because I find something hard to believe does not mean that I am trying to be an "e-thug" and "accuse him of lying."
God damn. You would have an aneurism if you went into the Kills section, man. People call BS there all the time; are you going to go in there and call all of them e-thugs, too?

Is this true? and if it is, what kind of engine am I supposed to put in it now? I looked up some sites for rotary engines and didn't find any engines that were 11b. I think I'm in desperate need of help!!!!!! otherwise i guess i'll just get another engine like the one i have in now and try to get other ways to make my car run faster. what a drag. any advice is greatly appreciated!!!!!

Since you don't know what engine you have, and apparently neither does you dad, pop the hood and start looking. Get a Haynes, or the FSM online, and start learning about your car. If you don't, it can get expensive quick. Especially if you go to a shop and tell them you want your 11b rebuilt. P. T. Barnum would love to see you walk into his shop.

Coz your new to the motor industry stick to a mild port 13B for now.
Once you got the hang of things you go fuely/turbo or whatever turns you on honey
There's also a good chance some fukin monkey is gonna rip you off once he puts 2 and 2 together. Either whip that bitches *** into place or get someone from this msg board to get some decent quotes for you.
Word!
