The mitsu ran more boost than that
I think it peaked at 12psi but I am no DSM expert
I know for sure it was more than 7-9psi
how small our turbo's are(pics)

By the way the evo utilizes a 16g on its 2.0 liter motor and the srt-4 uses one as well

Stock 1Gs (90-94) Ran 10psi.....
Stock 2Gs (95-99s) Ran 10-12psi......now that 12psi is a Spike at WOT but settles to 10.......the t-25 on a 2G Usually can only hold 14psi at a Constant it can spike 20psi and hold Mid way thru the RPM Band but always drops to about 14.......

Those pictures say nothing its not the saize of the compressor housing that makes the turbo its the size of the compressor wheel....look at the wheel in the 16G and the one in teh T25 the 16G wheel engulfs that T25's wheel. Also a Mitsu turbo will not bolt to the MS manifold they are not a T25 with a mitsu turbine housing like the DSM's they are a straight T25 with a T25 standard flange the only upgrade they would be able to go to is either a T28 from a Silvia or similar size or a T25/T3 hybrid. Oh yeah Red99 is right about the DSM boost pressures and the EVO hits 19.5 psi at 4500rpm's and settles down to 16 psi at higher rpms...as for lag on a larger turbo that is ridiculous...my blitz turbo hits full spool at 2800 RPM and will flow as much as a super 60 trim T3. I start building boost as low as 1800 rpm well within my driving range.

i don't know guys. i'm thinking about sticking a nice little Super20G on and swapping out the T25, whaddya think
i figure i should be able to get away with this since a bunch of people seem to think that the mitsu turbo's are interchangable
i figure i should be able to get away with this since a bunch of people seem to think that the mitsu turbo's are interchangablewhat did I just say.....Mitsu turbos are not interchangeable......it is a STANDARD Garrett T-25 flange on the turbine its not a MITSU housing.....Mazda doesn't deal with Mitsu turbo's they use garret IHI or Hitachi. I will say it one last time....a MITSU TURBO WILL NOT WORK ON THE MSP!!!!!!!

dude spit the viagra out and relax, no need to be a hardon. i was kidding. i know the Mitsu turbo's are interchangeable and that this is not a mitsu turbo and will not go onto my car. its all coo essay
like i said earlier, i will post pictures of something next to the turbo as a size comparison

The 2G used a T25, it was the Garret compressor housing and the center section with wick-type bearings, but the exhaust housing was a 6cm2 mitsubishi housing. The 16g ususally comes w/ a 7cm2 housing which will increase the lag a little bit, but not as much as you guys think. the T28 is a common upgrade on the 2G Talon/Eclipse. the 16g can be used but requires an installation kit.
The 2G DSM couldnt hold more than 13 psi consistantly cuz the piece of crap plastic BOV leaked. thats why the big ticket upgrade was to switch to a 1G BOV or get an HKS SSQV.
Btw, the compressor housing does have an effect on the compressor output/efficiency. the 16g compressor wheel, even the big16g wheel is oversized for the TD05H compressor housing, the smaller compressor housing ruins the compressor efficiency. the 14b is one of the most efficient turbos around. a Super20g would be killer on the MSP, except youd need a custom adaptor to mount the 100% mitsu turbo on the mazda manifold. the mazda manifold uses the standard T3 flange, not a round Mitsu flange. a serious upgrade would be the GT30, that would make SERIOUS power...like 500 WHP...except the tranny wont hold it.
The T25 on the MSP is a GT25...i dont know the second set of numbers, but that would dicate the AR ratio of the turbine housing, like maybe a GT2520 or something like that. it IS a GT series which means its true ball bearing CHRA. However, in the supra community there have been problems w/ Garret-type center sections w/ true ball bearings and wet-cartridge due to the style of the thrust bearing. The wet-cartridge has to use a 360* thrust bearing that is held in place by a spring, but if you opt for the dry-center section, you could get the 360* thrust bearing, and it would be screwed down, not sprung. im not 100% sure that this is the scenario of the MSP though.
This is essentially a Protege ES w/a turbo kit, a poorly designed turbo kit i might add.

Garrett T25
Look at it smart ass...that is the same Garrett T25 that is SUPPOSEDLY equipped on the MSP...and that exhaust housing sure as hell looks like a T3 style. I have the same exhaust housing on my Supra CT26, and its the same looking exhaust housing as the Ford Thunderbird Turbocoupe, and the Merkur XR4Ti, and any other T3/T4 hybrid used in turbo kits.
but, you know, ive been known to be wrong...but it sure looks a hell of a lot like what i know as a T3...besides, im just a girl

Hmm yep sure does,
But I have seen t25's with different foot prints so who knows exactly what foot print the msp spec t25 is using.....anybody can take pics?
Damn calloway

Perhaps he can take some of that sodium stuff you know they call it "Soft Peter" it's used in RTF and asylums.

T25 from RPS13
look at the turbine inlet. now look at this picture from Road Race Engineering's website.
T3 turbine inlet gasket
are you gonna sit there and tell me they dont look anything alike?

The higher the compression the longer it takes to spool. There is not enough exhaust gas to spin the turbine faster when you add more material to the piston and make the combustion chamber smaller.
Lower compression allows better spoolup, more timing advance, and boost.
Actually yes, they are not similar. If I look at a square and another square they may look the same. but the center section measurements are completely different and the location of each bolt hole is off as well.
