I know that I need a RB engine mount and oil pan and a 12a front cover but what ecu should I get if I want to put a 13b turbo in my 79'. And also what fuel pump should I get.

 

I would love to hear some info on this subject as well....I want MORE JUICE!!!

Thanks.

 

12a to 13b Racing Beat engine mount adapter
12a or 13b GSL-SE front engine cover, either will work
Turbo oil drain in the front cover (GSL-SE front covers make this easier since there is an easily-accessible spot for a drain)
FC fuel pump in-tank is easy if you have access to a good welder and a decent tank
~~~In-line pump I'd prefer a Bosch 044 since they're widely available and have an awesome following
~~~Maybe Aeromotive if you're feeling rich
Adaptronic ECU's are pretty decently priced and have a super following behind them

Give my YouTube channel a view, will give you an idea of what you're getting yourself into.

 

Alright thank you for the responses I was looking in to doing a gsl se back end disc brake swap and was wondering wether or not my stock rims would fit.

 

You could not have picked a harder chassis as a starting point.. That said, I am doing a very similar project myself. So the SE driveline... First the RX-7 SA v FB basics.

The every North American SA and FB had 4x110 mounting for wheels, except for the GSL-SE which has 4x114.3. You would need new wheels. Also the brake hardline pitch is different between the SA and FB.

NOW... if you can find a 1981-1985 GSL rear end (the one without vented rears) you can keep your wheels and perhaps adapt the thread pitch differences.

 

Even the thread pitch on the lug studs is different from an SA to an FB? That's crazy, I didn't know that..I guess I've never compared lug studs between the two.

 

If the 1st gen section had a mascot it would be this question.

I was going to link to myself asking the same thing in ‘03-‘04 to show I wasn’t picking on you, but I guess the post is too old to be saved. If I remember the consensus, it was that if you have to ask you can’t pull it off.

that being said there is a lot of fantastic tech on this forum that’ll help guide you, and everyone is nice enough to help you with the problems you’ll encounter on the way

 

Thank you as you can probably tell I'm new to RX7s well cars in general I got this car for free about a year ago I'm fourteen now and I can get my hands on a pretty cheap FC vert that has a 13bt and would like to put it in my car but my dad wants rear disc brakes if I'm going turbo, this build will probably take 2 years so it might be ready by the time I get my lisence my dad mainly has experience on older MGs and Triumphs so this is why I turn to the forums thank you for all the responses.

 

Awesome score at 14! I got my first one when I was 17, about to turn 18 in the fall of my Senior year in High School. Don't ruin it and keep it nice, that's all I have to say.
An entire FC Vert with the motor already in it? Why wouldn't you just fix this up and run that car? Better suspension, more aftermarket support, less work, chicks dig verts, probably a few other reasons I can't think of right now.
You'll need a GSL rear end from an 81-83 (small bearing), or a GSL rear end from an 84-85 (big bearing) in order to keep the 4x110 bolt pattern on your car. These are getting more and more rare and difficult to find.
It most likely will take two years, especially if you aren't working or don't have a few thousand dollars saved up already. These cars are a lot of fun, but the overall cost of building one adds up quickly - as with any project.
Your dad's experience will be extremely valuable in the build then, don't take it for granted.

 

Thank you I want to keep the car stock exterior wise (I'm only going to get enkei 92s and that's it) the FC I have access to was crashed into and is not worth fixing because it has also sat outside for ten or so years thank you for the information regarding lug patterns I'm going to try to hunt down a gsl se for the oil pan front cover, gearbox back and front end and some hardware I gave up on the stock rims. And yes my dad is very experienced but he is more of a finisher he has little experience with fuel injection or turbos but he will make everything a lot easier and it helps to have the support of a parent he's why this is possible thank you for the response!
