after a lot of searching thru the site i think everyone is going to say T2 but here goes (please dont just reply with "T2" cos thats not going to help :p)

I want as many narners as possible, im getting a morspeed 1380 engine and super squish 4 head rated at 15psi+ and i will have an fmic.

I do not want to modify the bulkhead so will have to use a mirage kit.

I have looked at a number of turbos now, lots of T2's, T2/3 hybrids, all sorts and when I think I might have found one A/R comes into the equation and I get lost.

SO what should I be looking for, and I guess I could add to this, does anyone currently have something suitable for sale?

Ah yes this was mentioned before. Is this a bit of a holy grail of turbos as they seem rare to get hold of.

How does it compare to the T2's and I'm guessing it fits straight onto the mirage?

There is one on ebay in the US at the mo.

Hi,
Nope it don't fit straight on, infact I'm not sure it will fit at all. It bolts straight on to the manifold, but the compressor housing is alot bigger than the T2. This causes clearance problems with the back of the block.
I solved this by putting the manifold on up side down!
Cheers,

I am in the same boat as yourself, wanting a little more than a stock R5 T2 can give. I haven't had time to research it fully but you can get a .47AR T2 that sounds ideal. If not a Rover tomcat T25 will fit the mirage if you relieve the block a bit.

It will fit, but needs a special manifold:

.64 is way too big for a Mini engine.
You need something in the high 20s low 30s.

Get a Rover turbo (Tomcat) T25, it is what some on here are using on Mirage manifolds for more than say 15psi.

Well that depends. A GT17 has a turbine AR of .47 and works fine on a 998. However, an earlier T-series turbo wouldn't work with such a large AR. The GT turbo T2 has a turbine A of .35.

In all cases for a practical turbo motor on a 1275 then .64 is too big, especially on a T-series turbo.

Right im dragging this one out of the cupboard! After driving the Mini around a few miles, i fancy something with a little more low down grunt.

Im probably going to go down the T25 Route, due to the fact that they are relatively cheap, and i can use the same manifold.

However i have a few questions i wanna clear up.

What Ars should i be looking for?

Can i run a Dump Pipe with one?

What car should i be looking to get one off?

Is it hard to connect the existing Drain Pipe to the T25?

I'm running a 1380 and will be running a turbo in the distant future. Turbo I've set on is the T3 and the displacement from the 1380 is a bit better than obv the 1275 and so on. The t3 i got has the 360 bearing and with the exhaust housing off the t3 turbo from the ford escort series 1 which is bigger as the t3 dies at around 5k rpm and this free's up the rev's but almost makes it laggier. but them im not to bottered by that cause im talking 20+psi in boost. just depends what you want, there's always a disadvantage with you want more nana's cause you gotta sacrafise something.
