Mitsu to T2 Garrett

[91shelby]

What are the pros and cons between them? i know that the Garrett will definitly flow better.

[90vntShadow]

More power, way better turbo, maybe a little more lag but more power on top.
Good luck finding any cons other than a little more lag.

[BluBaron]

how much work/cost would go into a mitsu-garret conversion?

[tryingbe]

If you buy my turbo, it'd be $280 + $22 (head gasket) + $25 (mopar head bolts) + $10 valve cover gasket and cost of coolant and oil.


89 TII complete garrett turbo, ready to be bolt on.

The only twos con are definitly the little lag and putting it together. The pros are... where do I start...

Lag is the big issue.

Really depends on how you drive your car and what shift points you like.

Personally i like the mitsu turbo for city driving. It makes power alot faster than a garrett does.. Especially when you want to get moving without revving to 4 grand and getting everyones attention.

"little more lag" is all in the person using it. I liked the 3" exhaust on a mitsu more than the garrett with a 3" exhaust. Mitsu was hitting 18 psi before 2grand like it was nothing.. car moved real good at low RPM.. I didnt dyno it at all with the mitsu.. i shouldve.

Swapped to a garret later on and low rpm accelleration was not as snappy. Did pull better once in upper 3rd and 4th gear though.

My dyno chart shows with the garret i barely made 50hp at 2,500 RPM, then 100 at 3500 then 150 at 4000 to a top of 190ish around 5-5500.

I can guarantee you the car was making more than 50hp at 2500 rpm with the mitsu.. it was already at full boost then.. but surely wasnt doing 190hp to the wheels at 5000 rpm though.

Once again.. all in personal taste.. city driving, low rpm, high rpm, etc etc. How do you drive and what do you want.

Something else you'll need is the Garrett oil and coolant lines. They're slightly different.

[TurboBuggy]

I did this a while back on my car. You dont need to remove the head like everybody says, you can use the oil line from the mitsu but it needs to be slightly adjusted, I got rid of the coolant feed line and drain line. The mitsu definitely makes more low end but I enjoyed the garrett a lot more

[EvilcowRoland]

Even if you can get to the nuts the hold the turbo to the housing, if they're original then you will play hell trying to break them loose. Either way, soak them in penetrating oil a good long while before trying to remove them.

Turbobuggy, you're running your Garrett without coolant lines? I realize some of them came with oil feed only, but I thought ours were designed to have the extra cooling for a reason.

By having coolant run to the turbo, a convection is created after the engine is shut off, this insures that the turbo cools down after spirited driving and doesnt roast the oil left in the bearings which could lead to turbo failure. Basically it serves the same purpose as a turbo timer, I just make sure I let the turbo cool down before I shut my car off

This is what ive been told anyway

my 88 lebaron convertible 2.2 turbo only has a 3 speed AT (i think) no OD. would mitsu be better with that transmission? also i prefer faster acceleration to top end power would that be better for that?

[Spee-D-Shadow]

I went from the Mitsu to the Garrett and yes its a little lag-ish but once its spooled it runs great. As prev. mentioned you will have to get the coolant and oil lines with the Garrett, I got mine all off a 87 Shelby Lancer T-II turbo, intercooler and lines and swapped it all onto my Shadow. I had no real issues, now being that your car is a 2.2 Auto and mine is a 2.5 5spd could affect your results. For over all power the Garrett is a better unit and it able to be up-graded should you want more power later on.

Can't wait to go T2 on the mini when the weather gets nicer!!!

All TD auto transmissions are 3 speeds. OD was V6 only. At least in America. Mexico got a turbo with OD.

Anyways, with an intercooler and some more boost, the Mitsu does alright. It definately spools fast, even though it isn't capable of the higher hp numbers. If you don't want to go through the trouble of pulling the head and swapping, just drop a factory or front mount intercooler in there and use a manual boost controller. The Mitsu is fine up to the 14-15 PSI range. If you do the mods and take it to 18, it'll really be running out of breath.

Agree with other posts,"depends on yout driving style" I am a "light to light" kind of driver.I like to be shot in the pants a little and then I drive normal.Or,When I get on the interstate.......Bat out of Hell!!! The Mitsu is great for that.Had a big HP Talon with a GT30 and it just didn't do what I was looking for.Boost on demand for me......
