Subaru EJ22 powered first gen Rx-7
11 Attachment(s)
As probably not tons of people troll the first gen build threads, I thought I would throw out my motor swap that I come up with and decided to move forward with.
So I'm sure most the people always ask why, well I like to say, why not. But the real story of it all was this car showed up to me with no drive train what so ever. And what it was going to cost to piece together a full drive train was going to cost way more then really it was going to be worth. So with some innovation and imagination this is what I came up with. The basics of it all: 83 chassis 94 Subaru Legacy EJ22 with full chassis and engine harness W58 transmission from a Toyota Celica Front subframe from a FC Rear axle from a toyota 4 runner If you want to scroll through my full build thread, the link in is in my signature. Now on to the pictures. First hanging of the motor. Attachment 683142 Putting the whole thing in for the first time Attachment 683143 Setting it in to start mock up of mounts Attachment 683144 Attachment 683145 Drivers side clearance Attachment 683146 Passenger side clearance Attachment 683147 Front engine clearance.

So I almost call that a mid engine. :) Attachment 683134 Header Attachment 683135 Drivers side header, steering shaft, head area. Attachment 683136 Attachment 683137 Finished Header Attachment 683138 Lets start the wiring, that is an entire car in a rubber maid tote. Attachment 683139 Sprawled out on the shop floor. Attachment 683140 Removed all the unnecessary circuits and unneeded extra crap. Attachment 683141 |

The final lay out of the wiring. Oh shoot, it's got a check engine light. :D
Attachment 683121 Factory Subaru fan mounted on the stock Rx-7 radiator. Attachment 683122 Lower rad hoses Attachment 683123 Rad and fan mounted Attachment 683124 Intake Attachment 683125 More mounting of crap, including most beefy strut bar ever. Attachment 683126 Putting the front of the car back together. Attachment 683127 First time pulling it out of the garage. Attachment 683128 Hood on and everything back together. Attachment 683129 Finished, painted and out driving. Attachment 683130 Here's a couple of videos of it, one of the first start up, and one of it out running and starting. |
Cool man!... Good job, are you planning on slapping a turbo in there?..
|
Not at this point, as I'm going to school and money is tight. But maybe something down the line, there isn't tons of room around it, so it would have to be some creative plumbing to get it to fit all right. And I'm not going to do that until I could afford to do it right, rather then slap a hacked up system in there.
|
That is pretty great. I've measured the fc for this swap but the motor is too wide by 2 or 3 inches. Glad you could shoe horn it in there.
Might as well stick with the motor and do some rallyX! |
Actually I'm planning for it to be a full stage rally car.
|
I bet that thing is fuuuunnn! Awesome swap!
|
Thats one way to make a subaru handle better, put it in a mazda!
|
Very cool

I'm glad you like it man, is that the 135hp motor? And did you make your own custom bellhousing for the w58? Thanks
|
yeah it's not tons of power, but it moves the car along just fine. with a full cage it comes in at just 2400 pounds.
As for the bell housing, no i didn't make it, but I am the one that got it made. I ran across a guy out east that was making bell housings to mate 4G63s to rwd transmissions, so i pretty much bugged him non stop for about a year seeing if he would even contemplate doing it. He finally said ok, so a packed up a chopped up tranny, a bunch of clutch parts and shipped it out to him. about a year and a half later he sent me his first one. and it works flawlessly. hes now making full castings of them and selling them. I wish i could do half of what that man could. but here's his site if you want to check it out. http://www.billsautofab.com/recent_mit.asp |
I wish I had the skills to accomplish something like that, everybody tells me my 12a sounds like a leaf blower. But I love the sound of a subaru and I love your car man!
|
hey I'm just a guy with a welder and some imagination. I really don't have any awesome fab skills, I just can picture how I want it to be and roll with it. I guess its probably not a bad thing the fact that I am going to school to be an engineer, so maybe those kind of skills will come in handy. Ok and the fact I have been welding for 15 years might have something to do with it.
BUt I think most anyone could do this, the bell housing, the rear axle machine work to match lug pattern, and the rear brake calipers were the only things I had out source, the rest was an angle grinder with a cut off wheel and a welder. No fancy tools used. |
Hey, awesome job. But one question: Why do you not used the original gearbox and adapt the engine with a adapter plate?

Ok this is awesome. Bookmarking so i can look at the pics on my laptop later
|
If anyone is interested I got a FB going of the things I’m doing with the car, because you know the internet needed another thing about cars.
I kind of gave up on forums years back and really haven’t been back much. Except to find parts. https://facebook.com/mazdaruMS |
Wow. Somehow I missed this project. This is awesome. I like Subarus.
