So about a year ago I pulled a 1978 Brat out of a barn that was sitting since 1992, so about 20 years. I never owned a brat before but I knew I always wanted one. Got the thing running by rebuilding the carb and doing a complete tune up. Needless to say the H.P. of the tiny 1.6 was not my style and read that it was next to impossible to do a EJ swap. Wont fit, will not work, and the biggest excuse why cut up a mint condition BRAT.. HA HA.. Heres how I found her....

This is the brat cleaned up right before the project started. This brat is a one owner brat with really low documented miles. The guts for this thing is next to show run no cracks, no wear and tear, pretty much driven 2,000 miles a year...
I drove it 50 miles then straight to friends Hot Rod shop in Spokane WA. for a a little fab work.. whoops lots and lots of fab work.

Looks like an awesome project.

I have to say i'm in the "why mess up a clean, low miles, 2 owner brat?"

You are kinda ruining the long term collector value.

Don't get me wrong, your making it a cooler car to drive and own and enjoy for a while so I get it.

It's just personally I would keep this one original.

That's all I've got to say about that

Thanks for your input but this brat is never going to be for sale and is going to be passed down to my son. The collector value is not a worry for me. I have 2 restored Chevrolet Impalas for collector value. I started the swap to have a 1 off Subaru not to mention all the people saying It can't be done.

I have the original window sticker, sale sticker, canopy instructions/warranty, dealer notes/checklists, business cards from the dealer, 1985 nationwide dealer list of phone numbers, owners manual, and baggy that the keys came in for my 1985 Brat. She came from Subaru of Tacoma. :D

Cool build, interested in where this goes. :popcorn:

You need an UEL header for the Suby rumble. And then chances are some sort of custom cat back for best fitment on the Brat, and a decent muffler.

THE BRAT IS ALIVE!! AND SEXY AS HELL. Little problem with air in the fuel system because no surge tank{got to get one}but she runs out great. I think it is faster than a stock WRX for sure... The suspension feels great and travels done the road awesome. The P/S is crazy!!! Works almost to good, tap the wheel and the wheels turn pretty much all the way as if were on a lift. Pic's and video's to come.........

OCD.... This project was not easy and took alot of man hours. Start to finish it was about 7 months. There was nothing to go off and every part had to be thought out and then fabed. It was not for the faint of heart. Since this one is done the next one should only take about 2 months give or take... The trip has been fun but with everything 1 step forward and 2 steps back.. LOL

I second this.

I was also gonna say Zefy is someone you should talk to because he swapped a EJ series motor into a Gen 1 Brat. Also think he did the suspension and other such things like you did.

I would love to see some detailed pictures of what you did because I wouldn't mind doing this to my Brat. I'm more or less interested in what you did for the mounting the front/rear legacy suspension.

If you decide to make some custom brackets/kit I would be interested in purchasing these from you. I understand there would be some cutting/welding on my part, but I am truly interested in seeing how you got this all to fit properly.

This is a picture of the shorted Legacy crossmember and custom trans mount. Crossmember had to be shorted about 2 inches to fit the brat along with a custom trans mount made from round tubing. Also you can see the mounting brackets for the Legacy's A-Arms. See the kick rump roast power steering in the 1978 Brat, has this been done before? I haven't found a Gen 1 with P/S yet.. LOL
