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.



On 12th Jun, 2009 sx_turbo1 said:

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....


tell that to 3 tuners *wink* and 2 of them are very reputable.

i never pretended to know everything and i believe this is a forum is it not and public debate is what it's all about, so maybe we can talk civilised.

i havnt really looked into the garret gt series as mini's arent really my bag, hence why i said "i may be wrong".

i'm not looking for arguments here,

my other points still clearly stand though.

i'm pretty certain it would be easier to tune on part throttle if you used injection.

it also depends on what afr's the tuner is trying to aim for,

and yes tom if i didnt have experience i wouldnt have posted, and thankyou for answering my question.

thats fair enough buddy, but I still can't see where the problem is with mapping on part throttle. When I had my T2 I was still using a SU carb. Dave Walker mapped my engine on part throttle with no problem at all

Can you get a T25 with a 0.83 or similar sized turbine? If so, I'd agree that these would not be best suited.

However, I've never personally seen one; the largest being the 0.63 from the nissans.

And I know they spooled up as we put one on Jimbo's, altough changing to a 0.48 was a lot better.

We do know (FACT) that the 0.63 GT turbines spin up very, very effectively.

Also, the T2 R5 spec is far from the 'be-all' of magic spooling. You want a super-charger-like spool, try the GT15 which is basically a GT version of the R5GT T2 with a small 0.35 turbine, but the far superior GT-series wheels.
I guess your 'reputable tuners' would say that this is a simply impossible combination?

Fact is, I could set up a business, install a Rolling road, call myself an automotive tuner (actually, no - I'd call myself an automotive engineer because my previuous job was as a 'washing machine repair engineer'). I'd then find one person with little to no knowledge, who I impressed with my barely adequate knowledge, and then went and passed this on to others, who despite doing what the tuner said was impossible' must know less beacuse they don't have a dyno.

I'm not trying to be a smart-ass here, but why don't you open your eyes, and look around at what folks do before telling them it can't be done.

thank you all very much for your help.. i have spoken to seveal companys now.

i am still unsure at what i want at this stage, both have good qualitys. i am more shunted to the GT side if i can be sure it will fit with the mirage manifold. i still need to sell my T3. i will be posting that up soon.

i did not mean for people to get in to any heated arguments, i am sure we have all had our fair share of problems and solutions to all things mini related.

i never said it cant be done.

just said that there may be a slight issue with part throttle that can be easily sorted by running it slightly richer.

1 tuner was alan thorndyke, i cant remember the name of the other tuner but my friend was recomended to to them by members on here, and he spoke about the issue with him and he said he agreed and said that just run it slightly richer on part throttle and all will be well, and so he did and guess what??

his car is now perfect, just needs to go back for 1 final session and have the boost upped a bit.

I hate to move the talk away from boobs!

But dose any one know if it is possabal to fit the GT17 or GT25 on the mirage? if not can it be bodged?

If not it seams the T25 is next best? am i right in thinking this is just a better version of the T2 so it should fit?

I am new to the turbo sean so may sound a bit dum! and may need things spelt out, sorry

T25 is not 'better' it is from the same 'era' using the same technology. It is merely a higher flowing unit. Which might not be what you want...

As regards the GT17 fitting - I'm sure someone can confirm this one way or another.

I can confirm that a GT 17 will not fit on a mirage manifold. Well it will bolt up, but it'll hit the block when you put it on the car.

Paul S has designed a manifold that will allow fitment of the GT17 without bulkhead mods iirc. although I don't want to speak for Paul, I think it unlikey he'll be making any for others. Paul may be willing to share the design (maybe for money?) but you'l have to ask him.

Wouldnt be too hard to make the gt17 fit mirage manifolds would it?
