I am going to run a GSL-SE engine with a IDA in my GS, and i have a GSL-SE parts car, what should I swap over? Should I swap the fuel hard line and gas tank? I am taking the brakes, rear end from the car already.

 

I'd swap the gas tank for sure. I'm not sure you absolutely need them, but the hard lines would be nice too if you don't mind the work. Just getting new hard line might be easier.

 

when doing the motor swap your going to need the mazdatrix front motor mount...This alows the fittment of a 13b engine into a 12a chassis...the hard lines are not really important as you can upgrade to braided lines if you have the money and stuff...If you don't plan on up-grading or changing the fuel pump...run the gsl-se pump...run all the suspension...You don't need the hard lines for that, becuase from 82 and on the pitch thread are/is all the same...Take the rear end too, tranny, and drive shaft...

Click me for the Mazdatrix Picture of Motor Mount

Scroll all the way to the bottom of the page and there is a picture of the motor mount you need to put the the 13b gsl-se motor into a 12a chassis...

Click me for Motor Mount from MazdaTrix

thats the link and the price for the motor mount...

 

I am taking the crossmember of the gsl-se, from my research, they bolt right up. I already got a Carter fuel pump and Holley FPR for the carb.

 

yeah it will work but won't work...your going to have to do some bangining here and there to get it to fit properly...but it will work...the alignment of the motor and tranny might be off some

 

How do you plug up the fuel injector plug and oil injector plug? I am going to premix

 

Okay i miss read your little post there your taking the whole entire cross member and swaping it into your 12a chassis good stuff okay...

For me i used 12mm short bolts and some silicone worked just fine...You don't have to use anything fancy...I will post pics of what I did and how i plugged it here in a short bit...

 

How about the oil metering plug that pineapple racing sells?

And the Racing beat fuel injection plug

your call you can go with those, but that is all stuff you can pick up at your local hardware store...I couldn't bring myself to spend 42.00 bucks for simple nuts and bolts i can get right of the block...

 

So wait, i'm planning on doing a similar project using an 84 GSL and putting everything from my wrecked 85 SE into the 84 chassis.

Do I still need that engine mount? Because from what I heard, since they were both series 3 1st gens, everything would just bolt right in no problemo.

 

You need the GSL-SE crossmember to make it fit perfectly. Another other option is to get the RB mount bar to use on the 12A crossmember.

 

Do you know the exact size of the nuts and bolts that i need? The OMP plug is not that bad, but the RB one is way too pricey.

Also, should I run freeze plugs for the engine?

 

The oil injection plugs just need a little M6 set screw and some loctite. You can machine little inserts to cover up the injector bungs. You're right that you can swap the engine, mount, and crossmember between the cars, and there's no "banging" involved. If it's a full -SE parts car, I'd go for the suspension and brakes while I'm at it. You also might want to take the interior out of the SE if you prefer it over your 82. No freeze plugs necessary, as your coolant ports were never machined (water line to the throttle body) so they're closed off.

 

and there you have it....so just to clear things up if you have an 85 cinco letra the "gsl-se" and want to do the swap take the whole cross member and swap it into your 12a chassis...if you don't have the swap buy the RB motor mount to do the swap...

Like crit said take all the suspension from the se and place it in the 12a chassis while your there...

The only reason why i said there would be banging involved is if he/she didn't have the correct motor mount from RB or didn't have the se cross member to do the swap...and he/she was stuck with a 12a motor mount and needed some banging...

 

you can always just slot the holes on the 12a motor mount bar instead of buying racing beats bar.

 

I am taking out the brakes, the car that I am swapping the stuff to is a 84, not the one in the sig. I am going to use the backing plate, calipers, and rotors from the SE and swap it over, since that strut spindle already has the coilover perch welded on it. I will also take the rear end to match the bolt pattern.

 

Oh, okay, thanks. I was thinkin' i was gonna have to drop the 90+ bucks for one of those mazdatrix cross members... phew...

 

If the gs is 84-85 then the gas tank is the same.

 

Ok, cool. Just checked Mazdatrix.

 

The SE gas tanks are slightly different. They have a surge cup that the 12A models don't have. The pick-up and return lines are larger than in the 12A cars. The 84-85 have a pickup/ return plate that can be swapped to get the larger lines.

83 GSL and 84 GSLE Gas Tanks

Here is an 83 12A pickup compared to a GSLSE.

 

How about the 84-85 12A? since your was the 83. Mazdatrix say that they are the same.

 

Mazdatrix just lists the SE tank since it will work for the 12A cars and the SE. There are slight differences as mentioned such as the cup
