nissan t25 Vs. dsm t25
 

is the nissan t25 bigger than the dsm, also how is the nissan t25 compare to the 14b. Turbo mag says the specs are 56mm compressor wheel and 62-trim turbine wheel in a 64a/r housing and my compressor housing is .80a/r, i just want to know which is better thanks. ???

any one ???

Re: nissan t25 Vs. dsm t25
 

I'd go with the nissan t25 but lets hear it from other peoples whos them. I know the DSM 14b is larger than the DSM T25, but sure if the nissan t25 and the DSM t25 are equivalent.

Re: nissan t25 Vs. dsm t25
 

i think its bigger just not sure

Re: nissan t25 Vs. dsm t25
 

anyone else ???

Re: nissan t25 Vs. dsm t25
 

It's going to depend which Nissan T25 - there are many different variations.

If you could tell us what year/model of car the Nissan T25 came from, we might be able to help you further.

A CA18DET T25 is not the same as a S13 Silivia SR20DET T25, which is not the same as a 300ZX T25.... and so forth - you get the idea.

However, there is only one type of DSM T25, so you don't need to clarify that one.

Re: nissan t25 Vs. dsm t25
 

i'm not sure but i posted the specs above :-\

Re: nissan t25 Vs. dsm t25
 

I used to have a Nissan style Garrett T25 that was .49/.48, I never used it on my car though, sold it off for a T3 before I had a chance to put it on.

I wonder how that compares to the DSM T25?

Re: nissan t25 Vs. dsm t25
 

My mistake - I don't know how I missed those specs above. :-[ Yours (9ray turbo) is a decently large sized T25 - at 56mm major diameter on the compressor wheel, it's going to be bigger / better flowing than the DSM T25, which is ~52mm, IIRC.

The T25 that EJ1 Wilcox is describing is most likely a CA18DET T25, and is about as small as they get - smaller for sure than the DSM T25.

The CA18DET turbo supposedly maxes out at about 210 crank horsepower or so - which is about what the DSMs which came factory with the T25 were rated at on the showroom floor.

Re: nissan t25 Vs. dsm t25
 

but how does it compare with the 14b ???

Re: nissan t25 Vs. dsm t25
 

It's going to flow less than a 14b for sure - and being a T2 frame turbo, it's going to be more restrictive on the exhaust side and create more back pressure than a 14b or a t3-style would as well.

Re: nissan t25 Vs. dsm t25
 

Your turbo...is the t25 w/ the .80 ar. which is the t25 that came off from the s13.

Re: nissan t25 Vs. dsm t25
 

Id like to see the comperssor maps for both turbos along with the turbie maps, but i cant find any info on them anywhere on the internet.

T25 compressor maps are ridiculously hard to find on the internet. Good luck with finding them.

I happen to have a set, from 45 trim all the way to 70 trim. :) Anyone wanna bribe me with something to share them? *laugh*

The DSM TD05h-14b compressor map is easy to find though, google will find it for you easy.

Re: nissan t25 Vs. dsm t25
 

thingy, honestly with all the info on this website that is shared and helps so many people its a waist for you not to share your valued info.

Ive found many tdo5h 14b maps, along with quite a few other mitsu and t3 maps, yet im still searching and searching for t25 maps. I dont think they exist on the internet.

I will be your best friend?

Seriously, I've got a T25 from an 88 300ZX and I'd really like to see a compressor map for it, finding info on these things is damn hard.

Re: nissan t25 Vs. dsm t25
 

if i'm not mistaken, nissan made a t25 for an sr20 that's ball bearing...i'd opt for that.

Re: nissan t25 Vs. dsm t25
 

so its smaller than 14b

Re: nissan t25 Vs. dsm t25
 

most likely

Re: nissan t25 Vs. dsm t25
 

Alright, alright, you guys twisted my arm.

I have good news and bad news for you.

Good news - I found a couple of the maps I had lying around - bad news, I could only find them for 45 trim and 60 trim T25's, although I know I had 50, 55, and 70 trim maps at one point. They're kinda rough and hard to read, so I gotta do some photoshopping to get them more legible. I will have them ready in a few days, most likely.

Re: nissan t25 Vs. dsm t25
 

Alright, you vultures. Seeing as I got flooded with messages as soon as I mentioned I might possibly have T25 compressor maps, I figured I'd come through for you guys. :)

The maps I have are from garrett, hand drawn by their engineers on graph paper - which tells you how old the T25 design is. ;)

I had to completely redraw it by hand in photoshop since it was barely legible to begin with.

I amthe ONLY free source of these on the internet that I know of. :)

However, I don't have any webspace at the moment to be able to post them. Perhaps one of the mods/webguys from homemadeturbo could put it on their server for me?

Re: nissan t25 Vs. dsm t25
 

id be glad to host them for you.. ive got 2 different domains.
