Im in the process of getting an exhaust together to put on my 1990 spg. I know i have to move the battery to put a sweeping downpipe in but all places around the area are charging MUCHO money to get one "fabricated". Im a welder machinest by trade in the marine corp and there stupid.

I could do it but i was looking and trying to figure out what i was going to do. Real question is how would i mount it to the turbo? And would it cause engine problems if i just attached a piece of exhaust pipe about 3 feet long and run it right out of the engine bay, like for say where the passenger head light would be :cheesy:

Also if i do the legal way what muffler would be suggested and if i didn't have a cat on it owuld it cause problems???

Semper Fi.... was a MOS 1833 myself, down at Lejeune.

What turbo is it? Garrett or Mitsu? Either way you'd need to weld a flange onto the DP where it'd bolt onto the turbo. You can find a Garrett T3 flange here.

I wont say anything about the exhaust going out the headlight. ;)

As for a muffler... I use a Magnaflow, as do others, and it's a really good choice. But muffler choice is like oil preference.... :roll: to each his own.

Thanks for the link now that i know what it looks like i can just go measure what i need and make my own. We have this outstanding lil machine called a Calypso Waterjet which you draw what you want on autocad send it to the machine and it will cut it out of any material you want. Has saved me lots of money, helps to put it on the gov'ts bill :cheesy: .

Lejeune huh? 1833 whats that? I don't know of that MOS. Im a 2161 machinest. I love my job because i can pretty much make whatever it is i need as long as i order and pay for the stock myself. But usually i find scrap metal laying around all over the place and i just slice and dice, do some work on a lathe or mill and i have exactly what i want :)

Yes i am, infact i just got back from Iraq 3 weeks ago. As far as getting called back i wouldn't be to extremely worried. There are alot of amtrackers around these parts so you should be pretty safe. Im with 2nd Maintenance battalion. Pretty much i fix all the stuff you guys break in ridiculous ways that i can't even imagine how it was broken. I did all sorts of upper track support arms, toe pedals, and something to do with a transmission. It seems like on the support arms they just fall off and rip every single bolt out with it requiring a bunch of helicoils. WOOOOO fun times :evil:

here's mine... moved the battery to the driver's side where the stock IC was. A few here on the board have followed suit. Not nearly as bad as moving to the trunk, & you can use stock wiring.

As for the pipe it's a full 3" divided downpipe with external wastegate. WG is a 38mm TiAL with a 8.7psi spring (base boost).

EDIT:
Going to make some mods to it while the turbo is getting upgraded. Adding the wideband bung and getting it jet-hot coated :cheesy:

Your face.






j/k we made something up custom, painted it black and bolted it down, but an easier solution would be to buy a universal battery tray from summitracing. I believe you can also use the stock one with a little work, but mine was in poor condition so I junked it.

If you do relocate your battery, you can re-use that factory cables.

I did this on my 86 when I put a DP on.


Also, a cheap option is this list:

Anyway, from what I remember...


All from: Http://www.summitracing.com.


Reducer kit with flange that fits T3:
http://store.summitracing.com/partd...15&autoview=sku

Fits the T3 with a little elongation of the 3 holes, and has a nice gasket to seal on the turbo.

This works great, and is very cheap.

Bend:
http://store.summitracing.com/partd...15&autoview=sku
3" with a 4.5" radius. We used a 6" radius, but the 4" would fit better, and be easier to work with.

Straight tubing:
http://store.summitracing.com/partd...15&autoview=sku
You don't really need this, but might as well make a nice long section 3" just for fun :)

02 bungs (I bought 2. I'm bumming a wide band from a friend for a while):
http://store.summitracing.com/partd...15&autoview=sku

We also used a 2" section of 2.5" curved tubing right off the turbo. Basically enough to clear the bolts...

Here is a 2.5" bend.

Cut some lengthwise slits, then tack, then hammer, then weld.



The price was right, what can I say?

I wish you were living round my part of the world, I'd give you my 3"dp from turbo to cat that I removed from my car. You could have the front mount intercooler too... it's just sitting in my garage in a pile (it's even exhaust wrapped!).

Took all of it off my 3-door classic to make it stock again. Jerkoff before me had a Unichip in there too and that was a PITA to get out. You could have that free too, it's just sitting somewhere in my trunk!
