My new RX-7
Hi, I'm new here, I've just bought a Series 4 RX-7 Turbo, the only problem is the engine is blowen. Now, I don't much care for the turbo, and I'd rather put a non turbo motor in it, What would I need to change to do so? Could I run it off the loom ECU and injectors that are in there? Or would I need to change it all to non turbo stuff?
I got the car for about $400 and it has a $1500 white paint job with red pearl in it, so I'm not too fussed how much the car cost to get going again, it's just a project for me.
I'll try and get some pictures up when I get the car this weekend.
Oh, BTW I'm in New Zealand, so finding engines is easy as, still exspensive though
Cheers for any help or advice

Well...if you dont want the turbo engine you are better off selling the whole car and buying an NA with the greater amount of money. Though this is my two cents talking so eh. It would probably be easier for you to get a non turbo car than it would be to buy an NA engine, ecu, and exhaust.

I don't know where to start? Is this your fisrt RX-7? Nice pick up if it is. I say stick with the turbo because NA guys are always looking to have faster car which to some leads to converting it to turbo. my 2 cents.

I just don't have the need for a turbo where I live, I have owned very quick rally cars before and I'm not afraid of them, it's more the reliability problems I don't want, or the fuel economy.
Doing exhasts and rebuilding is no problem, I can do all that, I've rebuilt many cars before, but I've never done a rotary before, so it would be a new experence. If it is cheaper, I should be able to rebuild the turbo one, but I's rather not.

Honestly.. if you don't want the Turbo model, sell it to someone who does. You shouldn't have any trouble finding someone to buy it... then get yourself an NA.
Wait a second - New Zealand. Doesn't that mean all of your RX-7s are imported from JPN? That means no-non-Turbo for you!

It's not good gas milage I'm after, it just a bonus to not having a turbo, if it's easier to put the turbo one back in, I'll do that, I just have a thing for non turbo rotarys for some reason.
I'd have the bonus of having the LSD + bigger brakes with this body too, not to mention the price they go for here, any money spent on the car, I could easily get back selling it if I had to.

To save yourself of buying new plates and all.... how about you just bypass the turbo - aka take it out and loop up the exhaust pipe?
Then you could put the turbo on if you ever wanted to and not have to make extensive changes. Your compression ratio would still be relatively lower, and you'd have some vacuum, coolant, and oil stuff you wouldn't need but overall it would be easier. This would result in low torque though and probably very lacking of power to rev high.
On the gas milegae, you can drive both a Turbo and NA just as conservatively and get pretty much the exact same fuel mileage. All s4s run on 87 pump gas.
You could also just reduce the boost (boost controller restriction) so that there is less stress on the motor.
On the fuel injectors, the turboIIs are slightly larger; other systems that you would have to mess with on the computer side would be the 5/6th ports.

Ok, I think I'll just put the turbo engine back in the car with a fresh rebuild, and drive like a nanna. Till I can afford to do more to the car.
Thanks for all your help guys

Hey! You have a TURBO NOW!! YOUR STUCK WITH IT NOW GO AND MAKE LOTS OF POWER AND DRIVE FAST!!! Rebuild it yourself, i did mine, and I didn't know I could do it! Its way easier than a Pisston motor, I've never rebuilt one of those, but I would try to! Its probably is just the O-rings, just pull it apart and replace the big rubberbands between the housings and bam! It'll probably hold out for another 70K!Just keep every seal in place and put it back together in reverse order! And the O-rings are like 100 bux for 4 teflon coated silicone ones, and you could use those when you blow it up agian as it is a turbo!!!
Unless it lost an apex.
Good LUCK!!!

yeah, I'm not too sure whats happened yet, I'll have to see, when we strip it down. I've built a 400hp Mazda GTX so I shouldn't have any trouble doing it if it's as easy as you say it is.
Cheers
