Sti swap into 87 gl 10

[Glfanboy9967]

Has anyone ever tried to do this and if so what exactly did you have to do Specifically to get the engine mounts to line up. Also where would I get a transmission adapter for the engine to transmission?

Been done many times. 

Engine mount holes need to be extended outwards. I can’t remember how far - it’s the same for any EJ conversion.

Thank you so would there be a kit for that or is fabrication required

You just need a hand file or a dremel. 

As for the adaptor plate various ppl sell them around the traps. The bolt holes of the EA82 flywheel needs to be elongated to fit to the EJ crank...

ADF and SJR both sell adapter plates. However the clutch may be difficult to get right. Probably best to read a few older threads to get a good idea of what's involved. Most people who swap turbo engines use the ej gearbox.

Have a read of this thread. You should get some ideas in here

I hate to do this, but time to fire up the old search engines. Been documented many many many many many many many many many times. There are probably thousands of different methods and combinations.

 

Hints:

Your '87 GL-10 is an EA82 chassis.

Motor mounts are the same for all EJ engines (as far as how they bolt to the engine crossmember). "Somebody" spent an enormous amount of their life compiling an EJ swap manual over 10 years ago, while it focuses on the simpler SOHC EJ22, a DOHC turbo version will be very similar.

There have been STi versions of the WRX model for 26 years globally, and 16 years in the US. While the mechanical challenges of fitting it in your car are basically all the same (To date, they all use EJ series engines), there's a huge variation in these engines. If you want more specific answers, ask more specific questions.

Presumeably your GL10 is already turbo, if not, you'll need a turbo engine crossmember or custom exhaust.

 

Spend a couple dozen hours studying all the EJ-swapped EA82 cars, even the simple EJ18 and EJ22 ones (and of course, the turbo ones). Then spend another couple dozen hours studying turbo swaps into base model Imprezas and Legacies.
