M12 - New Turbos

[Emubiker]

So, the Noble I bought back in February has decided to let go of one of its turbos. So I was left with a few choices.

1. replace with a re-furbished one
2. replace with new.

I figured if I'm going to spend £400 on a re-furb plus a couple of hours labour fitting then thats basically £600 (in my head). Therfore I might as well just replace it for about £1200. If I'm replacing one I should probably do the other and just get it out of the way as it will probably go soon too. But, if I'm replacing them both, surely I should use this as an upgrade point...... you can see it escalated quickly.

So the real question is:

What should the new Turbos be? The car does see a fair amout of track action so I don't want big power at the top of the rev range but want quick spool, plus more power. So what is the best option available to me?

Thanks in advance.

Is it a 2.5 or 3.0?

[Emubiker]

Sorry forgot to say. It's a 2.5

I would have a chat with Graham at universal turbos.

I was planning on GT2859s but maybe GT2560s is the way to go.

I have a set off my 3.0l. T25's. Car has 5000 miles on it. $850 for the pair plus shipping from US. In case you are interested?

Yeah gt 25' are probably the best ones for a 2.5

[Emubiker]

Are they not already t25s? Or am I missing something? Been trying to research today and gt2560 seems to come up a lot too. The 60 denoting something I can't quite remember now though.

[2.5bluenob]

I think it's gt25 rs 60 turbos that you want

[2.5bluenob]

Your turbos if standard will be half t25 and half t2.
The 3L cars had t25 turbos.
The gt25rs60 turbos are roller bearing and far superior in every way. But the price tag reflects it.

[2.5bluenob]

As bondy says. Speak to Graham at universal. They spec'd the turbos for noble from the beginning.

[mgbond]

GT is RS if you know what I mean.

When I look at the the turbo maps and from calculations I still believe that GT2859's are the way to go but before I go that route I was going to confirm with graham.

I did speak to him in the past and he did say the GT2859 would be a good choice. However even though my calcs don't sit right on the GT2560 map it still might be a better option.

[Emubiker]

So, now a month since my Turbo blew and Jetstream have been less than helpfull. Have spoken with them on 3 occasions now and been told I would get a call back with regards to when I could get the car in to them, how much it would be as well as being told conflicting info on which turbo to actually fit so I am now just going back to square one.

Surely there is another company, possibly even one a bit closer to home who could fir the turbos and know what they are doing with a Noble. The further North the better as I am in Central Scotland.

Thanks everyone.

I have just put mine I no GSR services in Beith based on a recommendation, I will report back when they are done. I would have thought they would more than able swap a turbo.

[Emubiker]

Please do let me know. I'd like to get it sorted asap

I will ask when I pick up my car at the week end, so far a very positive experience. Give them a call and ask for Colin if you can't wait

Don't forget that you will probably need a remap on changing turbos and the places that this can be done are restricted unless you have an unlocked ECU.
