Default EJ20 Engine Swap into GC8

When people say, you need a turbo cross member bar. Do they mean that It is going to be welded in/ or is it bolted in?

Any other parts I need to get it installed, if I have a long block engine?

Particulary I am going to swap in a JDM EJ20 with the 6 speed and JDM ECU.

Anyone done this? If so any heads up on what parts/wiring I should look for would be tremendously helpful.

Thanks
-Eric

Are you planning on doing this entire swap yourself?

Eric - Check the MWIC for yamarocket630's swap thread.

The crossmember bolts into the unibody of the car. You need to swap your current one to accomidate the EJ20.

The motor is the easy part of the swap. The PITA is the wiring. Supposedly, you can get a LHD GC8 harness and be done with it but I've never seen then advertised anywhere for sale. Dylan (downshift1) told me he could get these looms.

If you don't go with a LHD GC8 loom, you'll have to cut and splice like yama did.

Albert - Yes I do. I don't like paying people for what I can learn how to do (my philosophy) and I love to learn

mykr - I am confused about what you are saying, the GC8 loom is from what country? LHD, RHD? was the loom specifically made for the EJ20?

Thanks
-Eric

Yes it's been done...

my other 1/2 did a jdm conversion on his 95 nearly 1.5 years ago now... car is powered tho by an Autronic, rather than messing with wiring looms...

there have been some issues.. few bugs...
but when it's running right... nobody can touch it.

Yew I know I probably don't, but I have a lot of time on my hands. Also I am a freak when it comes to cars, This is the field I want to go in to fora career, so why wouldn't I want to do this by myself. Or with a couple friends for help, or maybe a couple techs to answer some questions I can't find answers for.

It's not that hard, just time consuming. The only wiring experience I had before my swap was a stereo. The only major install I'd done was a tranny on a 240sx. If you're intelligent enough to follow a wiring diagram and have some time on your hands you can do it. The only thing I'd recomend is getting a wreck. That way you have pretty much everything you need. They can be had for pretty cheap at salvage auctions. A major plus is you can sell off parts you don't need to get back quite a bit of cash. I'm confident that is the cheapest way to do a swap when it's all said and done.

As for the 6 speed, I've heard it is to large to fit in the GC8's tranny tunnel. I guess you could get out a hammer and maybe make it fit, but who knows. Plus why go for an expensive JDM EJ20 swap when later this year you'll be able to find some wrecked cars with EJ25T's right here in the USA.

i was liking the price because the tranny was included..

Now if the 04 sti trans will fit in my car that would be great, but man those parts are gunna be high in demand and that menas big money will be laid down on them.

fast n furious pt III

Thumbs up GDB 6spd tranny

6spd tranny will fit but it will cost ya. majority of the rear suspension/diff components will need to be replaced w/ this 6spd conversion. I am planning on doing the 6spd tranny swap once I get the $...

right now, just EJ20 w/ stock tranny for street driving.

well didn't they make a 6 speed for the classic body style?

I mean they had WRX's in Japan, WRX STi... Didn't any of the older models come with a 6speed?

Eric - LHD GC8 looms were made for European countries like France, Germany, etc. Unfortunately, you can't just flip a RHD loom around to make it work.

Most rally teams run LHD cars so looms are available for them. Not sure if they're custom looms or factory Subaru items though. I'd thing the former.

You could probably use that hammer that Ben is talking about for the 6 spd conversion on a GC but you might need a sawzall to cut the driveshaft down since the tranny is longer than a 5 spd.
