A body of mine has a DSM turbo, you know the ones from the talon and eclpises, well he upgraded his turbo and just has the old stock one layin around doin no good and hes willing to get rid of it cheap. Think i should pick this thing up and install in on my 2200? i mean i know it aint goin to do very much becuase its small and stock but then atleast i can say i have a turbo and will have everything that i would need to upgrade later on in life.

it'd take a lot of work (if its possible), you don't just pop your hood and slap a turbo on...





GO PATS!!!

The stock turbo's are way too small on thier sub 2.0L engines, they are WAY too small on our 2.2/2.4L engines.

its just a size and flange difference. not to crazy


"boobs now with Riboflabin"

you would probably have to make a turbo manifold for it since most ones for a J that I have seen fit garrett t3/t4 turbo's. Depending on how much boost it will hit smaller could be better, less time it takes to spool up.

Actually thats not true, sooner spool is not the key to a small turbo, its way out of its efficiency range, and all it'll do is inject super hot air into your cylinders, causing detonation and other issues. Having a correctly sized turbo has many more benefits over using one thats way too small. Don't buy turbo's because they are cheap, you can end up damaging your motor.

well thats why i asked before i went ahead and did this lol. So u guys basicly think its not worth it in the long run?


1998 Sunfire, 2.2L auto

there was one company that used dsm flanged turbos. hmmm what company was that. hmmmmm. oh thats right hahn racecraft

A turbo from a US-spec 4G63 would likely be too small, I had a 95 Eclipse GSX for a while and the turbo was the little turbo that could. But the 4G63s in Japan, on the other hand, had some big azz turbos for the early Evo and Galant models. I'm betting if you wanted to take that route you could go with a 16G and it'd work nicely. 20G would be overkill for the most part but if you built the sh*t out of the motor it'd make some serious boost.

So if you went with a smaller one, that is still good for our cars it should still spool faster though right? Versus say an enormous one? As long as its a decent size.

i'd yank a turbocharger off a 2nd gen sunbird gt. seems like it would be a practical size for a 2.2l. i'm sure you could make it work


People say that what doesn't kill you in this life
will make you stronger. I'm not sure if that is true
or not, but i do know one thing-You have to learn from
it and it has to make you better.......it has to.......

Still too small in my opinion...

Anybody that said size doesn't matter obviously never played with turbos before.

so is it possible for him to use that setup but just get a bigger turbo for it? i'm totally out in the dark with this subject but i'm very curious to learn

I'm sorry but which setup do you speak of?

I've looked at this sort of thing when I was working on my old Cavy. Using a DSM turbo is possible, and as long as you get a properly sized turbo you'll be fine. The flanges are typically not going to fit any manifolds for our cars since almost every kit available uses a Garett turbo, but buying a manifold and simply having the flange cut off and replaced with a flange that will work with the Mitsu turbo will do the trick. Everything else should work, downpipe I'm not sure but everything else I think would be okay.

if he had all the parts for a turbo setup from that talon or eclipse, he wouldnt be able to use them on his car right? i thought he had the entire setup but then reread and saw he only wanted to use the turbo, my bad.


----------------------------------------------------------------

so basicly the stock DSM turbo would only do bad things?


1998 Sunfire, 2.2L auto

It depends on what turbo he uses. The JDM 4G63s had anything from the 4G turbo (very small) to the 16G (good size), and some factory race engines had 20G turbos (too big). The turbo is about the only thing you can use, the manifold won't bolt up and the intercooler is a side mount that is pointless to use, a front mount will be more efficient.

well if you get a hold of a turbo like for the evo or something larger then stock dsm turbos. go here for a turbo manifold with a dsm flange on it....

Well...he wouldn't really be able to use anything except for the turbo & blow off valve.

Tubing wouldn't work, manifold wouldn't work etc etc.

The blow off valve won't work either I don't think. I guess it will, but not the way it's set up for the DSM. They have a recirculated BOV because they're a mass-air car and without it they run kind of funky. Our cars aren't true mass-air (I'm not sure if they're speed density, either, but beats me), so the recirc ins't needed. A standard BOV like one from Tial will work fine.

I'm not too keen on the DSMs but I do know that the 1st gens have a BOV and you can use it as long as you have the flange to go along with it....which is what I did on my setup.

Correct, they do. If it works, that's great. But I wasn't sure if the stock one would work by using the recirc, or if that part can be removed to vent the excess pressure into the atmosphere.
