thanks for the info and comments guys, right now I'm pricing out an exhaust since the stock one has a leak right before the muffler so I'm just going to do the whole turbo back. Probually 2.5'' all the way or 2.5'' downpipe to a 3'' catback with no cat preferrably

there would be no point in a 3" exhaust, or even a 2.5"dp into 3"....

the exhaust is only as strong as the smallest point, so you probably won't see any gain over full 2.5" over 2.5"dp into a 3" exhaust...

the only thing the 3" exhaust is going to give you is, the right to say "ohh i have 3" exhaust"

LHS?

I love them. I read somewhere the the srt4 motor and that one had parts that work well togethers. Crank, pistons, etc etc. Not sure if the head can be swapped.

Get a full 3" downpipe and system from FWDPerformance.com or ---------------.com.

They are the leading FWD Mopar venders for such items.

I highly recommend that you get rid of that 2.25" swingvalve housing as well.

Or you can get up with Racing Solutions and get all the mandrels and straight pipe to custom make your own setup.

Just remember one thing. When you put a free flowing exhaust on that motor/turbo combo, you'll have a problem with boost creep. I'll garanty it. The smart way to go is just repair the pipes that are leaking right now with a Dynomax over axle kit until you can replace the mitsubishi turbo with a garrett unit.

It's part #17488. You can get them from Jegs for under $90 before shipping. The kit comes with the over axle pipe, muffler, and tip. You will more than likely have to get a bushing reducer to make it fit on your stock intermediate pipe.

Dont bother with exaust untill you upgrade the turbo or you will get MASSIVE creep. Trust me... been there and done that. lol.

how does an upgraded exhaust create boost creep? it does'nt create boost creep on a honda, I mean all it would be doing is going from the stock 2.25 downpipe to a 2.5inch downpipe which came stock on later cars with no cat and just 2.5'' all the way. is there something weird with the wasgate on the stock turbo or the swing valve as the dodge guys like to call it. I figured since its bad why not upgrade with something better. I'm not doughting you guys by any means, I'm just curious as to how it creates boost creep, and how high does it go, cause if its not eratic or too hight I may be able to try and use it to my advantage

For some reason, when you open up the exaust on a car with a mistu turbo it wants to creep. Ive heard the WG hole can be ported, but the turbo isnt worth the trouble. Just watch the forums and pick up a good garret t3, and swap that on.

I've been browsing those forums like crazy lately and have learned a few tricks, and quite a bit about the cars themselfs. My problem is I don't want to replace the exhaust twice I'd rather just do it all at once. Did'nt the garrets come off of the earlier cars I beleive I think I sold one like a little over a year ago for like $20

The pre 88 turbo cars all came with garrett turbochargers. The non-intercooled turbos will have to be slightly modified in order to work on a push through setup. This just requires clocking the compressor housing, modifying the wastegate bracket for proper adjustment, grinding the turbine housing so it clears the intake manifold #3 runner, and getting an adapter flange for the inlet. All of the intercooled dodge turbos are garretts. Those are pretty much a direct swap in. The only Mitsubishi equipped turbo cars are the 88+ non-intercooled motors.

Reguardless of which garret you get, you will have to get the correct oil pressure and coolant hoses. They do not have the same fittings as the mitsubishi turbo you currently have.

I can't stress this enough...... DO YOUR RESEARCH!!!!!!!

For modification of the early garrett TI (non-intercooled) turbos, go to www.thedodgegarage.com. This site is basically the BIBLE for any modifications for your turbo dodge vehicles.

Porting the WG hole is a decent idea. However, the turbine housing itself is just too small. Any efforts to alleviate boost creep with a mitsubishi turbo and a free flowing exhaust is a futile effort. Unless you cork up the exhaust with a less than ideal muffler. But then why put on a large exhaust system in the first place?
