Turbo T2 model
Turbo Mini Forums

Hey,

I am new to the trubo side of things, i have had various problems over the winter but now finialy getting my engine sorted for my mini.

I have bought a metro turbo engine from good old flee-bay.

The 1 problem is i dont have the bulk head cut out. I am going for the mirage manifold and a T2 turbo.

Turbo technics said they would swap a T3 for a T2 i asked for the R5 turbo but said they had a shortage on somthing but said they could make up another T2 for me. I need to know a bit of information on they like a model number or part number. I like the T25 and read alot about them on diffrent sites, alot of people said they give better boost.

So my question is does any one have an information on a T2/T25 turbo that i can use with the mirage manifold?

thanks very much inadvance

Tell them to put together a 0.47 or 0.49 turbine AR T2, but with a 55 trim T25 compressor. That will be good.


But not as good as just going straight to a saab GT1752.

ok .. thanks..

i will see what they saw, but you recommend a saab T2?!

i might ask about that aswell.

thanks for the help :)

No, I reccomend a GT17. If you're spending 300 quid or whatever on a Turbo Technics unit, I'd just as sooner buy a GT1752 from a saab. There used to be someone selling brand new ones on fleabay UK for 350quid I believe - might be worth a look!

oh right .. sorry miss read that.

and they will fit the manifold with out the bulk head cut out?

I don't think the GT17 will, the downpipe won't anyway.

The old T-series are crap really.

"Turbo technics said they would swap a T3 for a T2 i asked for the R5 turbo but said they had a shortage on "
I have recenty purchased a stage 2 hybrid for the R5 from them, no supply issues? Did you ask for a std unit or hybrid?

hi shane

i asked for a hybrid ... should i be asking for standard?!

Well if the bulk head cut out is not to bad to do i might try it! just dont fancy lossing the heater!

You don't have to lose the heater, there are many cars on here with the bulkhead box in and a heater fitted.

Ts are plop, go gt

haha .. i like that mike!..

ok so bulk head conversion is not so bad!

i will have alook on the site of an "help files" as such!.. thanks for the help guys!

The difference in drivability compared to the t3 was huge with mine! Theres barely any lag at all.

I have herd there was alot of lag with the T3 thats why i wanted one smaller.

well i will keep looking around till i find what i am looking for still got a few weeks before the engine goes in.

Just buy the reccomended, tried and tested GT17 style unit.

Heed that advice, youll not regret fitting a gt17, i promise. If you have a T3 then by all means fit it. Then go to a Gt17 and youll see the lovely difference lol.

haha ... ok .. i know i dont want to use the T3 .. its between the GT17 and T2... i read in another post that mirage was looking at doing a manifold for the GT17 or GT15 bit of a smaller unit, so i might call and find out if they have compleated it yet.

I have to admit, I was anti T3 untill driving t3 tones car a few weeks back, that totally changed my thoughts on big turbos, would like to experience the gt17 for myself tho.

ideally you need the renault 5 turbo, if you speak to www.crturbos.co.uk they'll be able to help you out.

the t25 and and saab turbo's and other variants are a bit to large for the mini and you'll be getting full boost when it's time to change gear which is far from ideal.

now,

the t2 r5 turbo is tricky to map, because it kicks in so low down the revs (my mates is pretty much at full boost by 2k) it gets tricky to tune the part throttle, think he's got it sussed now by running the part throttle rich.

the tuners reckon that if he had the t3 it wouldnt be an issue.

maybe this is why rover used the t3 in the first place???

any way the t3 is to large and requires you to cut bulk head, so maybe try turbodave's suggestion?

or get a renault 5 t2 hybrid, with a bit of luck the spool should be slightly later but not much later though.

i personally believe the t2 gives the mini more street driveability, although it's not all that for all out pure power (although the stock gearbox can only take so much) and the renault 5 maximum efficiency is 1bar (15 psi), the almost instant boost is great for terrorising streets though

4 or 5 years ago I'd have agreed with you, but these days the GT range have superceeded and improved upon the T range.

i may be wrong, but isnt the gt range quite large?

I'm sorry to be blunt but a couple of these points are crap.

T25 based turbo's do not behave as you describe below, I'll get stupid amounts of boost out of mine way before 3k revs. You will find some of the fastest cars on here are running t25's or hybrid t2's that are pretty much t25 spec.

*Before I blow the t25's trumpet too much it is definetly inferior to the gt17*

And secondly I think you may want to change tuners if he cant set up/map your mates mini on the T2, just because it has very low lag doesnt make it tricky to tune at part throttle so running rich to cover this is most definetly a bodge and advice i wouldnt give to anyone.

When I had a t2, and t25 on my mini I never had a problem with getting it mapped, don't know what tuner was mapping your friends car but he doesn't sound the best.

I agree with tom, the GT range of turbo's is way better than the T range of the 90's. GT17 range is in no way to large for the A series, infact the GT28 range works very well.
