Ok so series 3, 12a (6port 12a? I read bout them but i cant find which cars they were on, makes sense the latest 12a car would have em...)

Front disc, back disc or optional?

Powersteering optional or yeah?

kinda looking at a 85 GSL ;3 if I do I'd wanna do a low boost turbo setup to make driving more spirited and get the engine rebuilt / ported so if you got any info on how to go bout the turboing (I'll search if I get the car, tied between a T2 and the GSL...) ya think the 12a could be boosted for less then a grand (Not including rebuild)

thanks man I was looking @ this one https://www.rx7club.com/1st-generation-rx-7-1979-1985-vehicles-109/fs-1985-mazda-rx-7-gsl-%243300-799332/ could hardly tell if the back was disc

can you post a pic of a FB w/power steering (I <3 it) but I guess I can make change? iono my S5 fc's power steering was neat when I floored/went faster it'd get stiff

that guy has a engine bay pic but if 12a setup is like 13b-S5/S4, the PS should be right there

remote hatch open? Whats that? My bros 79SA has a button you push and the hatch goes GAAAAAZZT and you can open it, that? lolol

My GSL has everything Dave posted except for the auto trans, power steering and sunroof. I either have a rare GSL due to the lack of a sunroof or some one went through a lot of time and effort to make it a GSL and look 100% factory.

here are pics of a GSL grade interior, one maroon and one gray:

You do not have a GSL. Someone added the items.

the 6 port 12a was a japan only engine, the rest of the world kept the 4 port 12a.

cmanns

Yeah plus they're rare as hell, I just thought mazda woulda been cool and done it to the series3 FB, then gain they had the 13b-EGI later on...

I can't wait to see the car I'm looking at, if I do get a 1st gen my plans are to do the sus (drop it a inch), brakes, old school rims I want to get wider tires for sure, I want to keep larger sidewall I'll prolly get bigger rims so the sidwall wont be as large as stock. Then I'll get the engine streetported, should be a fun daily driver

i hate my 6 port 13b.... i wish i could get it to a 4 port by some miracle, or find a 12a, i wanna turbo it, found out from someone i cant cuz of the 6 port.
trust me you dont want 6 port, atleast no one iv talked to does and all convinced me i dont, makes a straight pipe harder, turbo harder, have to maintain them so they dont stick.... not good imho

cmanns

Anton, I enjoyed my 13b 6port. I could "feel" them open literally, and the FC VDI worked too at higher rpms I felt it kick in.

My plan on my old fc was a 6port turbo before she died... I was just curious what cars the 6pi 12a was in, then wikipedia had my answer even though wikipedia is where i read about the 6Port 12a



& thx guys, hopefully I'll be picking up that 85 GSL soon, gonna have a lot of things to do =D

the 13B EGI 6 port in the GSL-SE as one of the most, if not the most reliable and longest lasting rotary engines built by mazda. you'll see no complaints from my corner.

cmanns

^wish I coulda found one of them, did you swap yours in?

peejay

Japanese cars only. US RX-7 had the same engine '83-85. Lightweight rotating assembly (good) and coolant-based oil cooler (bad).

Rear disc standard, but IMO it's mainly a cosmetic thing. The rear drum setup works about as well, and the handbrake is actually useful.

Optional, not standard. It seems like most Series 3 GSLs that I have seen had no options *but* power steering, like people were buying it that way because it was the cheapest way to get P/S. In actuality, the power assist was mainly necessary to deal with the added weight of having power assist... but some people are afraid of the idea of manual steering, I guess.

Depends on how resourceful you are, but you're probably not going to be able to rebuild it, given that rotor housings are NLA and the rotor housings are the *first* things to wear out in a 12A. Blame the 3mm seals.

The cheapest and easiest way (in the long run) to have a turbo 1st-gen is to drop in a Turbo II drivetrain. Aside from the actual drivetrain, the most expensive bit will be the custom driveshaft required. The N/A transmission is barely strong enough to deal with the torque a strong nonturbo engine can produce...

yes, because of the durability and smoothness of the engine, i found the exterior and interior colors of my liking and performed the SE drivetrain swap on an 85 GS. its been a very worth while project and i'm extremely pleased with the car. here is a link to my two threads regarding the entire swap with pics: https://www.rx7club.com/build-threads-293/85-l6-gs-se-project-restoration-822222/

dont get me wrong, the EGI is great just not that many options for customizing it. I still need to make a few more mods to my exhaust to get my Aux ports working better. And it has some power, around 4k that think hauls hard. i will peal hard through first and second and some of third no problem

i'll agree with you as far as the modifications go and the limited scope of them. and as far as the power is concerned and the ability to rack up some serious speed, my SE powered GS:

Sounds nice man, I don't have the resources for such a swap.

A rebuilder i contacted suggested a T2 swap (which would be smog legal/carb) in cali you cant do much, but I think I'll pick up a 13b S5 have him rebuild it and put it in, maybe get two cats or so smog passes easy with a small turbo build...
