Re:T28 a/r .80
No, it is not a T28. What you have is a straight T25. The specific unit you have is from the S13 red top SR20DET. It has a .64 a/r exhaut housing(way too small) and a .80 a/r compressor(not big enough)A T28 is a hybrid turbo. It is a T25 exhaust housing, turbine, and CHRA, mated to a T3+ compressor, compressor wheel, backplate. S15 Silvia T28s use a T04B compressor housing. It would be spooled before 3K, I'm not positive where though, I think the TD05 might be bigger. It is more the exhaust housing that you should be concerned with. The B16 is capable of alot of flow and high RPM. A .64 a/r exhaust housing will be way to small and will choke off your top end alot. I'm not to knowledgeable about DSM exhaust housing sizes, but they use the wacky cm2 measures... Also, if you use a nissan T25(a real Garrett T25 flange, it will have a completely different flange than a DSM T25(Garrett built specifically for Mitsubishi). I.e. a manifold that fits one, will not fit the other. Alot of people are very misinformed concerning this, too.

Re:T28 a/r .80
Thanks for bringing some light to this subject jalopy..
I personally like Hybrid T3/T4's for B16a's.. check out cheapturbo.com Lots of different sizes/trims availble. Jeff |
Re:T28 a/r .80
I just recently bought a T25 with .48a/r on the compressor side and .67a/r on the exhaoust side. Will this work good with my D16Z6 SOHC VTEC??

Re:T28 a/r .80
yup a t3/t4 hybrid would be nice. but im really after the street setup.

Re:T28 a/r .80
If you are hell bent on using a T-25 flanged turbo( non-DSM) the only unit I would go for would be the Nissan Pulsar GTi-R turbo. It has the largest exhaust A/R available. It also has a.60 60 trim T3 compressor. Very nice and streetable. I think this would work nicely. Would you be using an HKS manifold? They are getting harder to find. I got mine from NOPI.COM. Also, FYI, having gone this route, may I suggest going the T3 flanged turbo route. Trust me, it will be just as streetable and possibly cheaper. Just do alot of homework. Good luck.

Re:T28 a/r .80
I think I'll be getting the hks manifold for the t25. But the t28 and the t3 turbo will fit without a problem right?

Re:T28 a/r .80
No! There is no flange overlap. A T3 Falnge is different than a T25, which is different than a DSM, which is different than a T4, which is different than a, well you get the idea.. I hope. Please do more homework.

Re:T28 a/r .80
Lots of differnt flange styles guys, it can get very confusing..
T3 T4 Greddy JDM Garrett T25 All look incredibly close.. They each have rectangular flanges. But do not bolt up. Mitsu turbos mainly have circular inlet flanges. Jeff |
Re:T28 a/r .80
The Greddy, APEXi(SOHC), and HKS all use standard Garrett T25 flanges. They all make custom exhaust housings for thier applications. The T25 flange is more common than T3 in Japan.
