I've been in the dsm game for quite a while. Back in the early 2000s I had a bolt on PTE 57 trim turbo, a maf trans and an safc2 which was a blast to drive (I think it made 383whp 333ftlbs). Now I've been working on my buddy's 16g car and he's ready for something bigger. Only he is cheap, and does not want to ditch his fp manifold. Question is... where did all the bolt on mitsu housing turbos go? Only options I am able to find now are FP turbos (which I love, but cost too much for him). Is there anything of quality out there still? Not looking for some Chinese cx racing turbo. He currently has a e316g. Thanks

Buy a used FP turbo then. I’ve seen greens and reds go for $400-$650 fairly often. And if he can’t afford that then he can’t afford the clutch and fuel upgrades that go along with it either.

Seems like everything's becoming scarce these days. Holsets are the most common out there with the Mitsu style housing from the looks of it. Found these in the classifieds:

68HTA is a fantastic turbo for anything up to 450whp

If you go the Holset route just remember they’re physically large and they like high boost pressures to get into their efficiency range and make any power.

I picked up my used internally gated FP Green with the better HTA73 compressor wheel for $500 about a year ago. They are out there, just have to look for them

Thanks guys, I cannot imagine that there is little to no demand for a mitsu style bolt on these days... I currently have a 71 hta on my wrx and it's pretty fun, too bad they stopped making it for dsms. Thankfully my buddy is not in a rush, so I will have to keep looking on the classified ads. Chris, very nice find - but he runs his ewg on the o2, so it won't work for him.

I believe you can still get precision turbos as bolt-on; at least the website still says so.

Be sure the click the Watch button in the Parts Classifieds to get email alerts for everything that gets posted in there - here's the link for it:

Vegas, where did you see that? All pte turbos appear to be t3 or t4 hot sides

For example:

Loss of interest in the platform (overall) and $150 16G's on eBay killed the market. I can still build whatever you want assuming the parts are still available, but FP currently has bolt-on turbos available with compressors ranging from 51.2mm to 62mm so they're your only option. Don't forget a 1G is 30 years old now.

I'm pretty sure the Precision DSM housings are donezo, and Bullseye may no longer be in production as well as a few years ago I bought all their remaining DSM-flanged manifolds which, at the time, was 22.

I guess everybody is making WRX parts now

That’s where the money is at. The Subaru tax is f***ing ridiculous and these kids today are willing to pay it

It is 2021. Put a T3 manifold on the car and quite limiting yourself. Why after 30 years is this the only community that chooses to handicap itself with a shitty turbine footprint?

Because DSM owners still don’t want to pay the money for an aftermarket manifold. That’s why interest in making parts for this platform has dwindled down to almost nothing

They should see the cost of other popular current platforms, and be thankful we don't pay those prices That alone...should make them spend a little more $$$. I know some like me out there know and still do the "keep it simple" route on DSMs. Bolt on for good decent power...but like BigLady said...those days are getting old.

False. We still have very talented people out there making parts for our platform. One being a vendor on this platform @MorrisonFab, ArcherFab, and Raven Fab...im sure im missing others.

We are lucky to have some great fabricators in this group, but I too would go T3/T4 and have options. I have already went T3 and only my 90 GSX is still on a DSM flange.

FP makes something for every power level you’d want in a bolt on housing.

Gotta love all these people that come on here calling everyone cheap then you look at their car profile and it's worth like $1200 on a partout. Then they talk about how nobody uses t3-framed turbos because they're all using mitsu-framed but the entire premise of the thread is that mitsu-framed turbos aren't really available either. One should just conclude that this platform just isn't that popular and that's why there isn't a ton of money behind DSM parts. It has never been popular and therefore much less likely to attract people with money to spend. In the 15 years between me getting out of DSMs in 2006 and now I've seen ONE 1g dsm and maybe less than five 2G dsms driving around Texas. That's less than 6 DSMs out in the wild between 4 cities in one of the most populated states in the country OVER 15 YEARS.

Morrison could be working on Subarus, R32/R33/R34/R35 Skylines, VWs, V8s and be making double what they are from a DSM manifold. In reality, $1,649 for a manifold, o2 housing, downpipe, wastegate plumbing solution that is specifically tailored to your setup, is not a lot of money. Combine it with a junkyard HY35 for a $2,000 setup, you aren't much behind what you would be paying for a bolt-on type turbo in a Bullseye housing, except it would be much better.

Heck, even for the FP Red, it's a $1,400 turbo plus wastegate, o2 housing, and optionally the manifold. That's a wash.

The people that can afford to pay the prices for those parts, buy other platforms. Those that can’t, usually buy a DSM. There are a handful of people that know the value is a DSM and how cheaply we can make these cars go fast. But most people nowadays want to buy a 13 second car off the lot, throw $4-5k at it and be happy with a 12 second car.

With the cost of an entire hot kit starting at $1500, most people shy away because they prolly paid that much for their entire DSM!! 90% of DSM owners out there have never felt 400whp, so a simple 20g on a stock manifold is perfectly fine for them. Those needing more are more the exception than the rule. There just isn’t a big market for tubular manifold for our cars

Wow, I started this thread and stopped getting notifications on it, so I have been asleep at the wheel a little bit. I honestly think you all raise valid points... On my personal GSX I switched to a T3 setup 10+ years ago, even while using a FP turbo (FP3586HTA). The reason I asked was because a friend of mine loves the FP cast manifold which only comes in the stock flange.

I'm also not too brand loyal, currently I own my 99 GSX, a 2011 wrx, and a 2006 S2000. I see how these vehicles have much more bolt-on options available, options that used to be offered to our platform.

That being said, our DSM's are getting old, but I feel the love for them is not gone. I either need to convince my buddy to go FP Red and keep the FP cast manifold, or swap to a t3 for more available options.

Find the FP DSM HTA(76/82/86) series turbo for your friend! I ran the 76 for years and loved it but recently upgraded to the DSM82 which I love even more haha Usually one pops up in the classifieds.

A cast T3 manifold is like 100 bucks shipped. Assuming you can handle the o2/dp situation, there's really no reason to stick with the Mitsu footprint unless you have a cheap e16g or live in a state that requires a visual inspection.

From the FP home page, they are for some reason listed under "Classic 4G Style" then "Turbos". Anyway, there are 6 pretty nice ones listed there.
