Upgraded Mitsu turbo from FWD performance

[CowtownBooster]

Has anyone here used one or heard anything about it? Aside from it having a 15g compressor wheel, I am kind of in the dark about this creature, what kind of power could be expected from this combination?

For the money to upgrade a piece of junk, into a slightly better flowing piece of junk, is a wasste of money... put whatever wheel you want in it, the covers are still puny and you still won't make big power, boost creep would still probably be a factor, and for the money, you can buy a garret, and you'll be much happier. The only reason I can see for anyone doing this is if they were in a racing series that mandates the stock turbo, and you're trying to fool them into thinking its still the stock mitsu... but then, that makes you a cheater....

Cant polish a turd when refering to those turbos on our cars. Smaller liter cars could have some good benifits, but that is not a turbododge.

LMAO well that settles that! thanks guys, appreciate the input, garret it is then. time to go to the TU website...

[CowtownBooster]

turd polishing! yay!

I don't want you to think that I was bashing FWD performance, just the turbo... you could buy a garrett from FWD performance... not saying not to buy from TU... just saying not to buy upgraded mitsu turbo from FWD performance, not that they are a bad company. I would say the same thing if TU offered a mitsu upgrade.

Has anyone actually bought/tried one of these 15G Modified Mitsus? I race in NHRA/IHRA stock class and the turbo P/N's are checked (ie, I can't run a Garret in 2.5 T1). The turbo internals are a little "gray" though (no specific restrictions or modifications mentioned). Might be a good option for me, if I know what the real benefits are.

They are not as "gray" as I had hoped and they did check it during tear down

They have the compressor inlet inside diameter,the wheel dimensions and the number of blades on both wheels.They also have the casting numbers as well.The national record has been set twice in my minivan with a bone stock Mitsu turbo with 90k miles on it.......so it can be done for sure

When I started my NHRA stocker project a friend of mine told me "you gotta know what they know".A terrific peice of advise! So I contacted NHRA Tech and had them send me the turbo specs that they had.They were a little reluctant to cooperate at first.I told them that any stock specs that could DQ me from a race should be public information.They gave in and sent me the info

What class are you currently running in with the latest class changes? What is your minimum weight with driver? What is your factored HP?

What are your goals for your NHRA stocker?

I would be happy to help you if I can

I'm think the car will end up a B/FS car. It's not done yet, so I don't know the actual weight. But, for B/FS, the minimum is 2810 W/Driver. Factored power is 165 (last time I checked). The last time this particular car raced, it was in A/FS, but it was also a T2 ('89 Daytona C/S AGS). And all of the classes changed anyway. It could run 1.5 under then (and it was actually at B class weight). I'm not too worried about being able to run the index .

I've got a brand new Mitsu from Mopar. But, I thought, what the hell, if there's something better that I can get away with...

I didn't realize they'd check that much detail. Did they actually make you tear down the turbo?

[Shel-Game]

I should've added - I only plan to run a few regional events. I think you have to get so many grading points to be eligible for a national event, right? I probably won't be eligible this year. I don't really plan to try to set any records either. If the car can run 1 under, I'll be happy.

Is there a different level of teardown at a national vs. regional event? There are so few TD's running NHRA/IHRA around here, I figured they would only be able to check the casting #'s anyway (ie, they wouldn't know what they were looking at).

Would you mind e-mailing me the specs you got from NHRA?

I have a Sundance that I've been working on for that class.It has the same minimum weight and NHRA factored HP

During tear down they measured the inside diameter of the turbo inlet,counted the blades on both wheels and checked the numbers on the compressor housing and the turbine housing.None of the required the turbo to be disassembled

If you attend 2 or 3 of your local Divisional races you should be able to attend any National event that only requires 2 or 3 grade points.Of course they must also be running the stock class at the particular National event that you choose

As far as I know the tear down proccedures are the same.I had to remove the cylinder head.They can also make you take your oil pan down but I hear it's not too common.I've also heard of them asking for particular components off of your car like carburetors,turbos,ect. so they can inspect them.

I'll send the turbo specs if I can find them again..........I haven't needed them for awhile
