well i have a 83 with a blown 12a and i just bought a 13b with the ecu and all the wires for a $100 and was wondering what all i need to drop it in my 83???

djessence

A couple things off the top of my head. You either need the front engone mount 13B into 12A thing from RB or the 13B cross member.

Probably need different fuel tank/upgrade it to the GSL-SE or set up a surge tank.

Bigger fuel pump and FPR

Maybe even fuel Lines

Can probably find a few more things with a search.

djessence

Well actually. 13B is pretty vague now that i think of it. What year, series etc of 13B. That will likely determine alot of what you need. Most of the above applies either way

PercentSevenC

To be specific, you need a high-pressure, EFI fuel pump.

If it's an FC 13B, you'll also need a 12A front cover and distributor.

It has been covered a number of times before, I'm sure you can find all the info you need.

damn your the one that got that off craigslist. good score.

You'll need a fb front cover and oil pan (gsl-se) to do it right. Also, because it's an 83, you have a beehive oil cooler if it's stock. You'll need to change that out to a front mount. you'll also need a gsl-se front mounting bar. The one you have now sits back too far. the swap is well worth the couple hundred dollars it'll cost you, but to make it cheaper and easier, I'd suggest you start out with a carb rather than efi.
Good luck

Dont mean to hijack but I'am doing the same thing (se donor car) so is pretty much drop in? My car is a 79 model , the se trany is no good so What clucht combo can I use with the sa trany? Thanks

josh20

the motor is out of a 85 se it came with the front mount oil cooler

In that case you should be pretty much plug and play. The things to be prepared for are; On the 83 the engine wiring harness comes in through the drivers side firewall. on the 84-85 it routes through the passenger side firewall. To keep the stock fuel injection system you may need to change the dash assembly out also. You will need a higher pressure fuel pump to feed the fuel injection (an oem replacement gsl-se pump should plug right in).
I don't think fuel tank replacement will be needed until you hit HIGH horsepower (250+), in which case you'll want the se fuel tank for the internal baffle that's not found in a 12a fb tank.

what all you guys are fogetting is that if you plan to run your 13b fuel injected youll need all the sensors off of an f.i. equipped rx. i am talking about mass air flow sensor, throttle position sensor, and others i cant think of now. you could also go the other way and go carbed which i hear is a hell of alot easier you wil still need an intake for a carb . the only one i found is from racing beat and i think it costs about 250. then you still need a carb.

either way you go you guys are gonna have a fun learning experience with your cars. if your not absolutely sure what your doing it is harder than you think.

bstrange99

Don't get scared. Just pay attention to what you're doing. I totally agree that you'd be better to go carb. The efi setup is a big project. You almost need the whole donor car to rob parts from.

Its not a big deal if you research it correctly and ask the right questions.

Dropping an SE engine into a 1st gen is basically the same work as dropping a 2nd gen EFI engine into a 1st gen.So,you can use any info pertaining to TII or FC N/A engine swaps to help gain knowledge.
Yes,the SE swap will be easier than the FC swap since the SE engine is made for a 1st gen.But any 12A equipped car will need quite a few mods done to it to accept an EFI engine.
You will NOT need to rip out the dash.Nearly all the EFI control wiring and boxes are located on a single,large harness that runs out the right side of the firewall.There is also no need to splice into the existing harness that is under your dash.The gauges and idiot lights have absolutely nothing to do with EFI operation,so dont worry about that.The main task is to simplify and adapt the EFI harness' that come with engine,to physically fit in the receiving car,then run power to the appropriate places.

EFI is better than carbs in nearly all aspects.Those that just give up and run a carb will never know what they are missing.It just takes time,patience and the ability to research and read flow charts.Once you are familiar with the systems and functions,EFI is very simple,especially the archaic injection systems the 1st and 2nd gens used.

Josh,

To answer your transmission question. The transmissions for FB's are all interchangeable and have nothing to do with engine or what clutch you use.

josh20

well i got my motor in yesterday and I'll i need to do now is wire it up but i haven't the first clue where to start any help would be much appreciated and do i need the throttle cable off a se cause mine on my 83 comes up to short
