What's The Difference B/n Gt2560 Vs 2860?

[Phatboy]

Hey guys, I have searched around, but not sure about the answer.

I am looking for the one with the better response. I don't really mind about top-end speed.

I thought the GT2560 would be better for this, but then I read somewhere that it's the other way round??

It's for an R34 GTR with adj cam gears, AFMs, boost controller+PFC, 600cc injectors, pods, dump/split pipes.

Thanks for all the help.

If you want response its the -7/-9's

Not the -5 which are the bigger brother... this has been covered a fair bit, almost too much

Easy to be confused here because they were both once called GT25xx .

Basically there are two turbines in that group , I'll call them the OEM spool friendly one and the high performance one .

The first in my lists is ~ 53mm OD in 62 trim and the other is nearly 54mm OD in 76 trim .

Nowdays Garrett call the first one GT25xx and the second one GT28xx .

HKS's numbering system is an old one and doesn't differentiate ie call both GT25xx . With theirs you just have to know by searching ie a 2510 has the first type turbine where a 2530/2535/2540/GTRS has the second type .

In RB26 specific their GTSS has the first type , the SR GTSS version has the second type .

Have a look at the turbobygarrett site and note the GT25xx range and the GT28xx range .

If all else fails note the turbine trim size 62 and 76 , a dead give away .

Hope this helps , cheers A .
