Just finished with the 02 housing and wastegate dump last night. The welds look ugly, and they are for the most part, but it should work nicely and ugly welds won't really matter when it's all stainless and will be ground down and then wrapped in header wrap.


There are more pictures of the 02 housing in the gallery.

The intercooler pipes are absolutely beautiful, I'll get more pics of those and the other new stuff (BOV, turbo, wastegate, etc...) as I put it all on the car on Saturday. I'm looking forward to having a running DSM again and not having to drive the beater Evo everywhere.

Oh God, it must be so rough!

Nice parts BTW!

Sweet custom job! It does the trick for waht you need!

Nice! Good job!

Thanks guys, I'm actually quite proud of this piece obviously. FP wanted 425 for their unit and an extra 200 to get it to dump back into the 02 housing for the wastegate....so I spent about 300 in supplies to make my own. Not too much savings but it's nice to make something for the car rather than just buy it.

I've never fabricated anything this complex before and to see the thing in person, it's quite nice and very functional.

It would have looked 100% better, but I've never welded stainless before and it took a while to figure out the optimum settings in order to get the cleanest, strongest welds. The intercooler pipes were tig welded and man, they are marvelous. If I ever outgrow this mig welder, I'll be able to do truly professional quality stuff with a tig.

BTW, here is a pic of the FP 02 housing that mine replaces. Yeah, theirs is definately prettier.

Yours has... what do they call it? ohhh yeah a Personal touch to it! the important thing is you have a self accomplishment touch for you in the project that not many, hell maybe only a coupe people ever to have done this!

Harder to appreciate when just seeing the pic, but this O2 housing is HUGE. A full 3" housing dwarfs the stock pieces and even most of the 2.5" tubular aftermarket ones.

And hey, as long as it flows, if you're wrapping it in header wrap then the prettier pieces are even less important.

The FP piece may be prettier, but it still ain't pretty. You did a helluva job saving money and gaining welding experience in the process.

That piece looks awesome Kris, bet it flows plenty. The only ugly part is the welding, and maybe the use of straight pipes instead of curves, but the welding is all the MIG's fault. TIG is where its at.

Its a hell of a lot prettier than the only fabricated part on my car, my little tranny stiffening bracket.

I'll trade you beaters for a day... Hell, I 'll make it easy and trade you for a year.

That Looks Brutal My welds are alot worse and I always give respect to a do it yourselfer....Uhhh Like ....um Yourself...Anywho good job and lets see these IC pipes

thanks for the complments guys. Unfortuntely my home internet connection is down so I can't upload those pics of the IC and intake pipes.

Over the weekend I installed the 02 housing, turbo, IC pipes, and BOV and then fabricated a downpipe (with flex section) and got the car running. Can't really say much at this point because 15 psi is rather low and the car is hog rich, but at this point I'm just glad to have the GSX up and runnign with time to spare for Cordova. I'll probably be taking it to Battle of the Imports this sunday too if anyone is interested in driving up as well, I've got a small group going at this point including a certain GT4 3SGTE turbo MR2 that I spent quite a bit of time on earlier this summer.
