Help I Need Advice
I blew my engine in my RX7 and its time for a rebuild. The comression ratings are 135/135/135 in the rear rotor and 135/80/90 in the front rotor. I blew my engine because i ran my car lean.
I have a limited budget of about $3,000 to fix my car and get it running right. So here is the question.
-Do I take the risk and rebuild my engine and hope that i dont need to replace the rotor housing or any other major engine parts?
-Do I buy another TII engine and rebuild that?
-Do i buy a Cosmo engine and install that into the car and part out and sell my current engine?
I want to buy bigger secondary fuel injectors and ive heard that if i go with 720cc fuel injectors and can keep my stock ecu and buy a S-AFC.
What would be the best solution for getting my car running?? If you have tried these different options please tell me how much it costed you for everything. The current mods on my car include the following below:

135 psi on a used TII engine... mmmmmmmm I'm having some difficulties to figure that out...
The brand new engine has around 125 psi, but don't quote me on that...
I would re-do the test if I was you, you can even bring your car to the mazda dealer and have them check your compression with their special tool....

In your sig you have a boost controller listed and no fuel managment listed, hmmmm , let me guess, you just turned up the boost and thought it would be ok??? LOL How much boost were you runnin? how many miles are on you rotor housings?
If you have never built a rotary engine (and i'm assuming you need your car runnin ASAP) I would say for you to send it off and have it rebuilt for you or just order one from somwhere.
If you think can build it yourself then just buy a kit and build it, and you might want new housings (if its your first build, buy the video that shows you how to do it)
a full kit should be about $1000, if you need housings that would be from $4-800 (depending on where you go and if they are brand new or low mileage and whatnot). If you are wanting 2 720cc injectors it depends on what brand you get, but it will probably be like $2-300 (www.rceng.com) <<<go there. You can get a S-AFC II for about $2-400 (depending on if its used, where you get it and shipping). I'm assuming you have the stock turbo, so while your at it you might as well send it off and have it rebuilt (hybrid) (call BNRsupercars and ask for Bryan (205)640-1193).
So by the time you build it yourself, get injectors, a S-AFC, and get a hybrid built for you it will be like $28-3200. Add alot if you have to HAVE it built for you lol.

Please fix your signature glick, it is well beyond the limits that the admins have set for signature length. Refer to the forum rules if you have any question on how to change it, otherwise if an admin sees it they could delete it completely without warning.

First off i do not need my car running ASAP. I am from indiana and there is still snow on the ground so i have a winter car. I am looking to get this going soon though.
How much is it to have my turbo rebuilt, does that include porting the wastegate?
If i get a SAFC-II would that support 720cc secondarys and a ported rebuilt turbo?? How much can you do to a car without replacing the ECU??

Seriously though, if you get a 720cc intectors you will need a S-AFC (they will support even more than that), and you might even wanna get a chip from a place like rtec (click here)(its not really be a "must" or anything). I'm not sure excatly what it cost to get your turbo upgraded, it will depend on what you go with, and yeah he can port the crap out of your wastegate LOL. Just call BNR and ask for Bryan (more than likely he will be the one to answer the phone) the number is (205)640-1193, and while your talkin to him you should go on ask him about building your engine (unless you planning on doin that yourself).
