Alright. I have seen people with turbo charged 12a engines and I don't quite understand what I need. I would really like to know what a list of parts and their importance would be. A shopping list of all the parts would be really nice.

 

welcome to the board.

unfortunately, it's not that simple. any one of us could reel off a list of parts for you to get and it could either help you or bury you. no offense, but who would be doing the work because you don't sound ready.

you're going to have to do some more leg-work and see exactly what you want to build. carb? blow-through? draw-through? EFI? power? powerband? you need to make a plan before asking people to recommend parts. search the Gen I section and see if something jumps out at you.

 

I agree with the above post. You are going to need to discuss this with a professional because there are too many variables and it depends on what you want and how much money you are willing to spend. I recommend contacting forum vendor Turblown as a starting point.

Also, here is a build thread if you want to get some ideas:
https://www.rx7club.com/build-thread...-build-950467/

 

I want to keep my 83 gsl as stock as possible with the carb and all. I don't really care about exact parts but like what are all the parts that you need to have to add a turbo? Like I know I need a turbo, new manifold, and an inter cooler but what other parts do I need?

 

Everything will need to be custom fabricated. There are no commonly available 12A turbo manifolds. Carb hat with a boost prepped carb underneath, turbo, intercooler, all the plumbing (custom fab), oil and water lines (custom), exhaust (custom). Oil pan need a turbo oil drain (custom). Some method to measure AFRs (wideband). Upgraded fuel pump with FPR.

And then unless you know someone familiar with carb tuning on a turbo rotary, you'll need to rebuild the engine.

Of course that ignores ignition. Typical way to handle boost with a dizzy is to lock the dizzy to some safe angle. Unfortunately while this runs well in boost (0.1% of your driving) it limits ignition advance under 99.9% of your driving resulting in poor fuel economy, lackluster feel, stinky exhaust and other issues.

Converting to a proper EMS solves the tuning issues but requires a lot more work (there are no off the shelf 12A EFI setups) and expense.

 

In other words, you are broke, you have no idea what you are doing, and nobody is going to convince you that you are making a huge mistake by trying to tackle this project by reading misinformation on the internet. You could have saved us some trouble by just stating this to begin with.

Anyway, here is a website for you:
Turbo FB Web Site - Boost for your 1st Generation Rx-7

Rotary Shack Mazda 12A Turbo Exhaust Manifold | Rotary Shack Store

Also, he could try to source J-spec 12A turbo parts, or maybe even find an old Cartech kit.

 

Corphish don't despair buddy. I started out just like you and met the same comments. The forum members who commented before have all seen new members waltz in and drop the "what do I need to turbo my FB?" question numerous times before.
First thing you should do is go to the build threads and read up on previous projects to get a feel for how much work goes into something like this. Secondly, find a reliable rotary engine specialist and sit down and discuss the options (blowthrough, draw through, EFI) and determine which best suits your goals in terms of power,reliability and driveability. Thirdly, don't jump in half assed. After sifting through the information and deciding on a way forward, spend some time saving up your cash and sourcing quality parts before starting your project.
Meanwhile, have fun with your car in its NA form, perfect your driving skills and make sure your suspension and braking system are up to par.

 

Yes, that and similar questions. In almost every case they end up screwing up their car and selling what's left of it for a huge loss on Ebay. In worse cases, they spam the technical forums with absurd questions like how to fit a rusty old F150 brake disk to their car, and then they get all upset when everybody tells them to just buy the correct brake disk. Some people are wired to have a difficult time in life.

 

I am broke but this doesn't mean I can't make money and save money. I just got 2 extra jobs so i can play with my car! I'm not trying to find a cheap way of rigging a turbo to my car, I have never even driven a turbo'd car! I don't even know anyone who could tune the computer! I was just curious if it could be done since I kinda like having a car that is different not only because it has a rotary engine but also carbureted!

 

I really hope as a child your father beat you or you still don't own a rx7. Those are some good reasons to go around posting on new members threads just to **** on their dreams. -.-

 

Never seen that manifold before. Good to know something exists but I wouldn't recommend it be used as is due to the very unique wastegate runner placement. For the price though it would be hard to beat and the buyer could have it modified with better wastegate plumbing.

The chances of finding a used Cartech kit are probably going to be close to zero. As for turbo 12A factory stuff, I remember seeing one, once.

There is no upside to having a carbureted car. Well, other than the fact that it already has a carburetor and presumably is running fine with it. Beyond that, carburetors are scrap metal and belong on lawnmowers, not cars. Is it really worth making an unreliable and poorly drivable abomination for the purpose of being unique? How many engines do you want to go through to accomplish this?

There are significant hurdles to building a successful carbureted turbo rotary which I have already laid out. I'm fairly certain Mazda never sold a carbureted turbo rotary. The factory turbo 12A was fuel injected with a primitive system (similar to the GSL-SE) and equipped with a knock box to retard ignition. It is my understanding that the knock sensor retarded leading timing only, though I must stress that is just a guess as the factory 12A turbo is super rare in North America and I've only seen bits and pieces of it.

If you are going to start this route, I'd suggest begin first by converting the engine to EFI and tuning it as an NA engine. Through that you will gain valuable experience and set the base up for forced induction. Once you're confident in tuning and the fabrication necessary, it's not a huge leap to go turbo (truthfully the turbocharger, intercooler and related are not the biggest part of it...it's everything needed to support it).

 

You may be "broke" but the INFO is Free on here and sometimes it is not exactly handed out to you.
Especially when it is has been talked about in great lengths over and over again.It begins to be like a broken record.
So for that reason the Info is posted you can often find it and read it when you start your search.You can sift out what you want and dump the rest.

I started out the same way so don't get upset if someone tells you "Search..!"..
Actually it is the BEST way to find the info and get the Info you want as other times someone may post Crap that you just do not need and may send you in a direction that is not even worth it.It can be the difference between getting the job done or saying "fugg it" and dropping the whole idea of even trying to do it.

remember you have only started on this Forum and inquired in THIS section so just think of what the Other sections have in terms of Info.
It is totally unexplored....big Game out there..go hunting!

 

i would recommend not only searching here but google as well. i completely resto-modded a 79 monte carlo at 21yrs old w/out posting a single question and with no prior mechanical experience. have the mentality that everything you could dream of has at least been done once, allyou have to do is ask google how to do it.

 

as misterstyx69 said, the advice here is FREE. so let me offer a tidbit more before you go derailing your own thread. around here, as on other car forums, you shouldn't expect to be coddled. you need thick skin. period.

Evil Aviator may not have stroked your sense of ego or need to be different (sigh! ... what does that even mean these days?), however i honestly did not get a sense of a personal attack ... AND MOST IMPORTANTLY, he took the time to provide you with relevant links. in your own words, you have little money, you don't know about turbo rotaries and i don't see evidence of your taking the advice given for you to formulate a plan and THEN ask better questions. that said, to your credit, i don't see evidence of the contrary yet either.

Aaron Cake gave you the closest thing to the parts list you seek. again, you have to do the leg-work to know why you need those parts. he also gave you some sound advice in maybe considering doing an EFI project first.

 

Most of the people on this forum are broke. It's no big deal. However, hotrodding your car requires a lot of skill and/or money. The less skill you have, the more money you will need to hire somebody who has the skill that you lack. You are going to need to spend a lot of money.

A cheap way of rigging a turbo to your car is to use the original carb and other old original parts that are not optimal for performance and/or reliability.

You could transplant a 13BT engine and EMS from an FC RX-7. It would require no tuning.

It is a God-awful difficult task to properly tune a carb on a turbocharged rotary engine on anything other than a drag race car. As the years go on, there are fewer and fewer people in the country who can competently perform this task. Unless you take a trip to Puerto Rico, it would be easier for you to find a tuner for an aftermarket EMS than it would be to find a tuner for a carbed turbo rotary engine.

... or you are not yet to the point that you can comprehend the good answers that you have received.

 

I agree that Puerto Rico comes out with some wild stuff, used to see a formula Atlantic 4age corolla racing at insane speeds down a mountain over there.
Corphish this reminds me of a story I read. A kid on this forum built a 4rotor all on his own, went to post on here and said what do I need to build a 4 rotor then posted his theories. The powers that be laughed at the noob, said it cost to much money, and he didn't have the skill and his theories were flawed. His next post... Pictures of the 4 rotor the NOOB to the forum built on a budget. Point 1 for noobies. Lol, my cell auto corrected to boobies. All the guys who doubted him had to pick their faces off the ground. If you truly want your baby to be a carbed turbo invest in knowledge and teach your self the skills to do it and it will be done the way you want it and at the most affordable cost. Now I won't lie to you. I received my turbo converted AUTOMATIC gtu(bought a 5 speed before I bought the car, I did drive it auto for 2 months, i'll post it in my build thread) not running. The previous owner did not research, had the wrong ecu, wire harness, fuel pump AFM, and the car sat for 8 years not running. It took me two weeks to go through it and I got her up and running, but I learned and self taught myself knowledge from this forum. I read so many builds and picked out the setup I liked from various threads. My car ran with my plan on paper before I ever touched it and she cranked on key turn number 3. Now that is a point for the old heads on the forum.
