Anyone running a GT2876R (aka GT25/40R)

[griffin dai]

I've got what I believe to be a Garrett 0.64ar GT2876R (GT25/40R) turbo coming this week, but it could just as easily be a 0.64 GT3076R as it was listed wrongly as a t28 and from the outside they look pretty much identical! I cant check the part no's until next week.

Is/has anyone ran with one of these? I had a 0.86 GT3076R on my old car and before that a GT28RS so was wondering what to expect with this one. I know it will have more lag then the gt28rs but how will it compare to the 3076? What kind of power could I expect from this as it seems an odd combination? This other one on ebay recons up to 480bhp!!

Any thoughts

I doubt the difference in lag - unless you have some mismatched components elsewhere - will be perceivable...
