Exclamation WRX running gear and motor in my 85 GL coupe.

We have started the full process of converting a 85 Subaru Gl 3-DR Hatch to street/track spec converting the powertrain and suspension to 2004 subaru WRX specs. The WRX doner car has been fully striped of all components we are using.
As you read this the GL has the engine and transmission removed and is sitting on a custom table we welded up on casters so the car can be moved around the shop with out the suspension in it. We are in the first parts of this project and have no real timeline in mind as we are taking it a day at a time.
This is a F'n huge project and not for the weak at heart. This is no joke either. Pictures will be posted soon!

The car will be utilizing:

SDS management.

Fuel Cell (for multiple reasons) as the suspension goes through where the stock tank is.

Stock WRX engine

Stock WRX transmission

Large Front Mount Intercooler

750cc Injectors

Turbonetics T3-T4 Hybrid turbo

40mm Deltagate Wastegate

Undecided on BOV

Stage 3 street clutch with light flywheel

Stock WRX suspension

Stock WRX brakes

Stock 04 WRX wheels

Full 7 point roll cage

Aftermarket gauges

I will update this in about a week with some pictures and more details of the process as it goes.

You are my hero. I've been waiting to do a project like this myself but I don't have the time. Make sure you do all the fuel lines... the new pump will run way too much pressure for the old carbureted lines.

EVERYTHING is getting replaced, no worries. The GL body is just being used as a shell basicaly. Even the steering components are being converted. CB!

Similar, but the 85 GL needs much more structural modifications etc. to fit the motor, trans and suspension. Also shortened drive lines are needed. Front suspension is not too bad, just top plates and some slight magic but the rear suspension is slightly nightmare-ish. Also frame rails are too narrow on the 85 GL and while the cross member is a help it needs major mods to fit into the whole working eqation.
I like what you did there it is a noteable transplant. People should be envious of what you got there. We are doing more the pro race mock-up approach. Will probobly be doing a 2.2 stroker set up if we can get COBB as a sponsor. We will see how that all goes. Local sponsorship has been a breeze but the national companies are tricky, even though Christian hacked on our 04 wagon last year on the COBB dyno for almost 10 hours...CB!

um, so here goes.

pre '85 is considered gen I with only minor changes between the older EA71 and EA81 models between '78 thru '84. (headlights, grills, ect.) old school '85+ is considered Gen II, with the exception of the hatch (seen here) also sometimes called the threedoor, which would get parts suppliers confused with the three door RX. but, case in point, this is an EA81 pushrod OHV powered Gen I built after '84. (the only subaru past model year '84 to keep the EA81 in the USA.)

let's not forget that there are variations of turbo heads for the EA82 motor, so when someone says Gen II or Gen II turbo head and are talking about the EA82, that's a different story.

FWIW, my '88 I had to order parts from an '84 because parts stores would get me EA82 parts. if you were to see an '81 and an '89 they would be identical, minus the carb in the '89 would have an ECU, solenoids, an O2 sensor and TONS of vacuum lines.

Umm acutally Jon, a gen 1 car is pre '80 unless its a Brat then it was pre '82 for them. Gen 2 are the EA81 bodystyled cars like the hatchback you had. Then gen 3, is the EA82 bodystyle, like my RX.

The 4x4 was around 2200 IIRC. The modern components will probably bring the weight up a little but even a stock EJ20 in this thing will be a ROCKET!!

Yup, that was the thought. Unfortunatley the engine will not be stock and the car may be slightly faster than its original powerplant. He he...all kidding aside there are two main reasons were doing this and many smaller reasons really.

Reason # 1. To make a street legal rocket ship that will be utilized at the track.

Reason # 2. A big F.U. to all those who said it couldn't be done...Hey we really do love our Subies and thats whats its all about.

oh hell yeah.
I have been looking to do this same conversion for a while now, but using the entire powertrain out of my legacy.
what struts?
what knuckles?
what control arms?
what axles?

I was thinking that it would work to ream the ea81 control arms for legacy ball joints and try to keep the suspension geometry similar to a 5 lug car. axles would probably have to be custom. I will build some coilovers with parts from stockcar products to be easy to use ea81 strut towers. hoping that the inserts are the same.

what are you doing for the rear suspension? I am planning to get rid of the torsion bars and run circle track coilover parts in the stock shock position.

please get back to me on this if you dont mind, I am really looking forward to building a 2100lb awd subaru.

I dont realy have the ea81 car yet so sorry if my questions are kinda stupid.

right now I am searching for a hatchback to do this on, any one know of one near me holla. the only prospect I have right now is a EA71 brat which will be a lot harder to fit an EJ so I am pretty sure that I am going to have to keep looking for a hatch.
