View Full Version : what is this turbo? t2/ t25??
Stamped on the compressor housing: Garrett A/R .48 M24 L
On the turbine housing is: Garrett .64
The compressor inlet ID is 54mm
The compressor outlet ID is 40mm
The turbine fan DIA is approx 45mm.
Would this unit be a t25.? if so, is it a large or small variant?
how would this act with a std cam? spool up time etc
and also how would this act with a piper 285 cam.?
Sounds like a T28 of a 200sx S14 turbo, on a 5 gtt will be quiet laggy, .64 rear is large for a 5 even with a cam.
Get a small shot of NOS in there to make up for the lag and turbo will be fine:agree:

id second what james says there, if you find it too laggy then i could either supply you with a .49 t25 housing for you to fit or could supply and get it fitted for you
what size housings does a std T2 turbo unit have.?
im trying to understand the sizes as it confuses the hell outa me:scratch:.....
when does a turbo become a full t25? ie what are the minimum housing sizes for it to be classed as a full t25 unit?
what size was the 220/tomcat turbo unit.?

Tomcat is. 48 comp housing and. 49 ex housing. Full t25 will obviously have the t25 size housings,core wheels etc

The 200sx turbo has a bolt on inlet and outlet. Il have a look at mine when I get in and see if its m24. Whatever it is like james said the rear housing is very big and will be laggy.

Raj thats a T25. As the guys say 0.64ar will make it very laggy, 5000+rpm so it won't be much use with a standard cam. Switch that housing for an 0.49, if you can find one and it'll be much better.
thanks for the info fellas:agree:
has anyone every had a roller bearing conversion done on there turbo? as i see certain companys offer this service!

roller bearings cost big money but do reduce spool up times especially on t28 powered r5gtts

any idea on the price of a roller conversion fella.?
Ball bearings are about durability. They try and sell you them with the less-lag line, but really it makes sod all difference. They'll maybe respond a bit quicker after a gearchange. It won't come on any earlier than a journal. You can, if the oil is good, get away with murder if you have a ball bearing core.

:agree: I learnt my lesson on the weekend, don't fit a .64 rear housing Raj. Its far too laggy and spool is very slow.
Yeah bit big for a little 1.4, I think it's off an S13 200sx as I think thye had the smaller front T25.
