T25
Turbo Mini Forums

Hi all,
Just picked up a T25 from an Uno Turbo, it looks like its oil and awter cooled, does that sound right for the T25 ?

Will be water cooled and has an oil feed at a guess.

Ive got a T25 of a silvia thats the same.

Iain,

Would you know which way the flow goes?

T25 on a 1400 engine? I wouldn't have thought so...

fiat uno have never been turbocharged by a T25 , they were by ihi rhb5 or small t2's with the same specs of the gtturbo, the only difference is that they have round turb hsg inlet , this make them more difficults to adapt.

I 'm troubled by the fact (not concerning you directly Paul , but it's more a general consideration), that turbo nutters , even if they want to crap their too big T3 , prefer a t25 (created later to fill the range let between the t2 and the T3) instead of a T2 , the t2 are the smallers and so the best mached, we are turbocharging a 1275 not a 1800 ; t3 are ok from 1800 to 2500cc's , the t25 are from 1600 to 2000's; if we were using an engine with the revs capacity of 8000's it could be ok, but the mini engine, by it conception limit the rev factor so even if the boost can be highly upgraded, the T2 will match better as it corespond to the airflow demand

"The second generation of the Escort RS Cosworth was a bit more "civilized" than the first. The only exterior difference, compared to the "big turbo" version, was an HTT (High Torque Turbo) logo on both front doors. These cars, starting from late 1994, were fitted with a Garrett T25 turbo (much smaller than the huge T35, the T25 is using a T2 turbine and a T03 compressor wheel), the same turbo that was mounted on Fiat Uno Turbos!"

This was from a cossie site, seems the MK1 was an IHI and the Mk2 was a T2 or a T25, according to the enthusiats.

Hum hum, it's very difficult to match T03 and t2, t25 parts the hsg are differently mounted , the t03's are bolted ; the t02 are clamped, the wheels diameters differs a lot.....
difficult to mount T03 wheels on a T2/T25, about the cossies, I haven't any knowledge, but as you said, these 2 liters can use a t25 , a mini not , the unos no more .

I'll post a pic as the compressor side, has round inlet and outlets and the exhust has square inlet's and outlets. Its not a major problem in getting them adapted as I have access to a full cnc machine shop, all I do is draw it up, as dxf, email it done and a couple of days later, it arrives on my desk.!

Or I could do it at home on the father inlaws, colchesters and bridports

In relation to whats best matched to a mini and oversizing on turbo's, most men I'm sure when given the option of a small thing or a big thing, will go for the big thing then agian most women will too !

I went small, and ended up with big torque
