just ran my GT2860's at 1.75 bar, seat of the pants feeling is they run out of puff about 1.4-1.5 bar were as my HKS gt2530's were still happy. I did also change my manifold but I don't think it is related. At this stage my hks 2530's had a more on/off power with more efficiency up top and the garretts are more of a street turbo with good response but not the same top end that I like to run. I'll get a dyno graph done as I'm only guessing atm. I'm aiming for 500rwhp if the fall behind by over 70hp I'll upgrade.

The latest:

I datalogged 1.4bar and 1.7bar and found my AFR dropping into 10.8:1, I leaned it off a little to 11.3 and did some more driving.....well alittle more. It felt pretty sweet until I got into third and broke my 6th gearbox, lol. These turbo's my have promise yet.......

:) Now you should go in a car with 2860R's and tell us what you think...

Yes I changed from T517Z's to 2860R's..

Yes I have MUCH more response..

The T517Z's were good for top end, more suited to drag racing, will make good peak power...

No I wouldn't change them for anything.....

No I wouldn't buy HKS items, the price of the Garretts are too good refuse...

:)

Nengun are selling bolt on GT-SS s with bolts gaskets basically the lot for $400 more than 2860R's but you will have to find all the bits yourself if you buy the garrett turbos. You say the T517Z's were good for top end well they must be the 10.0 cm2 ones and not the 8.0 cm2 ones which are very responsive.

Ummm no dude, they were definetly the 8cm version and they were definetly not as responsive... :)

And I would put that extra 400 bucks towards some decent dump pipes....
