Bunch of newb questions.

New to the forums, just have a lot of random questions. If there is a FAQ page specifically for them feel free to post the link. What are common things to watch out for if buying an rx7? Are the stock motors setup on 2 rotor? I am familiar with the motor but do not know what is common to go out on them aside from the Apex seals. What are some performance parts sites for these cars? Do the Rx7's come with any unique features like many of the other japanese vehicles of these years did? Example (3000gt) active suspension and exhaust, also active aerodynamics. Any general information about these cars I welcome also. What horsepower are the turbo models rated at stock? How much boost stock? How much boost are they capable of producing max on stock turbos and how much to redline with a EBC? What size turbo's are they? Etc etc.. Im sure you guys get the idea. Thanks for the information/help.

Thanks Mahjik I read through them now from what I understand the stock turbo's go around 10-12psi stock? What are they capable of with a boost controller? These cars seemingly have a lot of issues that you really have to look out for and have a lot of preventive maintence! It's mostly small stuff thank god.. What do these vehicles top out at? Do they experience a "fuel cut" at a certain RPM? Thanks for all the info

Well, stock boost max is 10 PSI. I'm sure if you are in a cooler climate, you could see 11 PSI on cooler days.

What the stock twin turbos can reliably support is debateable. You'll see plenty of threads on it here. The most you would want to run on stock twins is at most 14.7 PSI. Even then, you will be reducing the life span of them since they weren't designed for it. However, simply plugging in a boost controller isn't going to allow you to hit 14.7 PSI. You'll need to open up the air flow of the system and some other mods.


I can't remember if fuel cut is by boost level or RPM... I'm sure someone will chime in and post the correct info.

Anyway, if you are thinking about fuel defensers for defeating fuel cut, that's not necessarily a good idea. The fuel is cut for a reason, so ensure that the engine either has enough fuel to operate or to stop it before it can run into a lean situation. Unlike most other cars, detonation is EXTREMELY harmful to rotary engines. It's better to just upgrade the ECU so you can adjust the Air/Fuel ratio and not worry about it.

Thanks for the great reply : ) Can you supply me with any performance parts websites and perhaps exterior addons also? I found a 93 Black RX7 by the local walmart. It goes as follows. Black exterior, black leather interior, 5 speed, sunroof, 97,000 miles, EXCELLENT condition, but it has been wrecked b4 on the passenger side. The man mentioned the passenger front and rear were hit and completely fixed. This vehicle also has 18 inch rims, a cd/tape player and I don't recall to much else.... I was VERY surprised at how the interior looked brand new for almost 100k miles... They are asking $13,500 isnt that a lil hefty for a wrecked vehicle but they claim it also has a clear title etc... BTW I noticed a switch on the console something like Exhaust gas or something like that? What is that switch for? Thanks again for all of the help!

You can check the banners at the top for most of the RX-7 stores, but here are a few that I have delt with:

http://www.rx7store.net/

http://www.rx7.com/

http://www.pettitracing.com/

As for the switch you saw, that's probably not a switch but the exhaust overheat warning light. I've never seen mine go on, which I suppose is a good thing. I think you might be able to trigger it with a clogged cat or something....

Make sure to do the usual checks on the car if you are seriously looking at it.

* Compression check
* Boost level check
* Drive it and let go of the steering wheel (make sure it doesn't pull to one side or the other)
* Find out as much information about the car as you can. What's been replaced, and what hasn't.

Good luck!

The FUEL cut is by BOOST (about 14psi) there is no REV limiter though there is a WARNING BUZZER thatsounds a 7500rpm (6500rpm for auto trans) the stock motors are rated 255 hp at 10 psi boost and published testing put the top speed at 178+- mph

Yes 13.5k is high for a collision repaired fd especially if it has 90K+ miles on the original engine - have the boost & compression checked as mahjik said - also check for Oil and/or Carbon in the coolant, either can be warning signs of an engine going bad

How well does the stock tranny and rear end hold up to stock and/or increased power levels? The stock motor is a 2 rotor correct? That is crazy these motors can go to 7500 rpm and still be good to go... They obviously must like high revvin and produce great numbers up top when modified...

well, i dont post much, this might even be my first post. but that is because i am just in the "gonna buy a fd but better read up and do my work before i pour ALL my cash into it" category.

anyway, i have read up on spds. and some of the top 7's run times from 8's up....stock is 12.8 or 13.8, i dont remember...

The stock tranny is good up to around 425 rwhp or so (a normal stock FD makes about 220 rwhp), so you'll have quite a bit of room before you'll need to think about upgrading to KAAZ or something else..

Of course, that doesn't include wheel hop from launching the car.... Too much wheel hop and you'll be tearing things up in no time.
