You've been told wrong dude. You guys got the 12A turbo. Hunt one down. Just treat it nice.. no cranking up the dial-a-boost till you've upgraded fuel systems.

Pele is right. Aus got the 12AT model RX-7. That's a 12A Turbo, STOCK!

no i have a 12 a which im looking at turboing

REVHED

The factory 12A turbo model was only available in Japan so any that we have here are private imports. As for the motor itself, they're starting to get a bit rare and therefore pricey which means they're not really worth considering because you can get a 13BT for the same price.

If you want to turbo the existing 12A there's no reason it won't last as long as you rebuild it and set it up correctly. And if you want to run substantial boost you'll need the low compression 12AT rotors. IMHO, for the money you'll spend doing this you might as well get a 13BT.

I suggest rather than starting a new thread you should have simply gone to search 12at and there is all the information from numerous isimilar questions.

turbocharging a N/A 12a is possible. i have seen 28 psi on factory components and regular 11,000 rpm burnouts everyday with only a port job on the engine. but,as for reliability this was a race car so the engine only had track time on it.

I first fitted a turbo to a car 30 years ago, a Lotus Elan. In those days no one know much about turbos and how it set them up. It was real experimentation time

Since then we have learnt a lot. There are a great number of Japenese high performance cars with turbos which really work. You do not get them in the US but Australia is being flooded with them. In Japan they quickly get rid of their car to buy the latest fad. The car are exported secondhand to Australia for a fraction of the cost, the advantage of also being righthand drive.

The answer to your questions

1. yes it is easy to turbo charge o 12a

2. yes the engine can easily take it if the seals are in good condition.

3. Jspec rotors are the technical way to go due to the lower compression, but are expensive and difficult to obtain with the appropriate counterweights.

4. There is little difference in the engine life given the same driving pattern, BUT because you have a turbo you love the high end power, use the top end more and this is what causes engine wear. I would suggest you would need an engine rebuild every 100,000 miles if you are going to use the car in a way that justified getting a turbo in the first place.
