The Turbo rat wagon ... scoobaru performance on a budget

Well a lot of people have been asking to see pics of my scrap metal built scoob. Figured I'd post up some pics of the whole thing. I gotta take some more, a lot of these are old already. I've cleaned things up and added more and better stuff... If I get some time, I plan on working on the car a bit tonight and this weekend, I'll update more then.

Anyway, the car was built out of spare parts and acrap metal. I got the car for free, a customer at my shop didn't want to fix it. All it needed was a crank sensor. New they are about $300 so he didn't want to spend the green. I took the car to scrap it and decided to use it as a winter rat since it was in pretty good shape, only had about 130k on it and was a 5spd AWD car. Car had no options at all, no A/C, no ABS, no cruise... a bare bones car. Plus it's a wagon, and I always liked wagons :)

Anyway, there was another wagon on my lot to be scrapped, it had a blown motor, so I stole parts off that to fix this one and drove it for a while ..... I always wanted to turbo a Subaru... then one weekend while staring at a pile of parts from my Supra project, I decided to drag out the welder.

This is what I did.

Cut up the stock exhaust and welded on a manderl bend for the up pipe.
Image

I needed some metal to form the rest of it with, so I went to the scrap metal pile and pulled out this Honda muffler. It had a stainless wraper around the muffler of a decent gauge, so I used it
Image

Getting it together
Image

almost done
Image

Here's teh Toyota CT-26 turbo I used. This is next to a turbo off an old 1.8 GL10 Subaru for comparo
Image

Here's the turbo all mounted up
Image

A shot of the downpipe with the divorced wastegate dump tube... when I hit full boost, this thing makes women and children jup from the sidewalks ... it also belches flames sometimes on a really hard shift
Image

another shot of the turbo on the car
Image

This is the first version of the setup. pipes are really sloppy and there is no scoop for the IC
Image

that setup proved bad, since on a hot day I was in a rush, passing some cars and in the boost. detonation got pretty bad, but I was commited and couldn't let off... I ate a piston... so I had to swap the motor

here's the new motor going in... a 200k + engine out of aotehr junk wagon.
Image

here's a shot of the Audi S4 Biturbo Bosch BOV I'm running... same one is used on Porsche and some Saabs
Image

With the new engine, I needed to not be lazy and actualy make a scoop for that IC... this was the plan all along, but I just never got to it the first time. Another trip to the scrap metal pile and :)
Image

The scoop works awesome... right now I'm running 87 octane on 5-6psi of boost.... I almost never get detonation. So far only once was it audible and that was comming out of a turn in high gear/low rpm on a high 70 degree day. In the winter time, I'll have nothing to worry about. :)

Here it is pretty much the way it is now. I don;t have any pics of the engine/turbo setup, But it's been cleaned up a bit and I made a cold air intake in the fender. I've got an oil leak to take care of and I need to put my MBC back in there so I can turn up the boost. I'm gonna run it inside though and mount it on the dash so I can twist it whenever I want ... also have some WRK suspension goodies and a DIS-2 (the new version with retard control) ... all that need to go on... probably pretty soon, hopefully this weekend.

That setup is like something out of The Road Warrior.
Looks pretty sketchy, but that divorced wastegate dump pipe is badass because you made it from scrap.

Correct me if I am wrong but isn't NY an inspection state?

How on earth do you get away with that?

I used to pay my local inspector $20.00 and he would give me the sticker no questions asked. If you do it yourself or you iknow someone then your secret is safe with me.

I miss Syracuse (as a tear riolls down my face)

It still has the 2nd cat and all other emissions equipment is on it. The dump tube technically fails it, but it’s only open during WOT, so personally it’s not a concern to me. Based on the fuel economy it gets it's less of a pollutant than most vehicles. I might even add an EGR system to help fuel economy a little more despite the fact that NOx emissions aren’t a problem in this car, though with the boost on, it might be in moderate load cruise situations. I'm not about to run a 5 gas analyzer on it during a load test though. As for how it passes….. no comment.

I'm a tree hugger at heart, so I'm not a fan of removing emissions equipment. If I could have done it without loosing the one cat, I would have. I might get a better high flow cat and mount it a little closer so it's more effective.

I would love to race/dyno test you.

Two modded NA motor wagons.

Wow.

We would kick some 2.2t ass!

so, I'm thinking of entering the rat into the Grassroots Motorsports $2006 challange ... what do you think, I know I can make it perform, but do you think I can make it look good enough to be competitive?

do it, Ive been waiting to see a ej powered car in the challenge. this looks like the only way to get in it and be semi competitive other than a really cheap SS. better yet, this motor in something like a gutted EA82 3 door. some stiff ass ebay coilovers so no need for nice shocks, used slicks, a few nicer power mods, some cleaner fab, and NITROUS could do ok. could maybe even be a top 10 finisher if it rains like in 2003! IIRC a subaru had FTD at the autocross. drag is out of reach for a subaru. that dude with the nova in 2004 and fiat in 2005 has a pretty mean chevy motor. low 10's. :shock: I bet its got really good ported heads, ~14:1 compression and a 250 shot or so.
you can do it, just clean up the hood scoop(fiberglass?), run some new beads over that downpipe with a TIG,and do a LOT of cleaning.

That. Is. Awesome.... A low-dollar setup that provides many smiles, I'm sure.

*Cough* Keep dreamin :razz: Though you probably would put the hurt on a stock SS.

I could make a Stock SS faster than that... with some... well a free mod, as DSMers would say. ;-)

You think you know, but you have no idea.

Are you going to be able to dyno it and/or drag strip it?

what injectors did you use? stock? turbo legacy? how does the maf deal with boost where its located?
