Just put in garret 2860-5 turbos . have a problem.

The dam factory dump pipes flanges are diffrent from the garrett's. The bolt holes don't even line up. WTF?

[Super_Dude]

Are they .63 a/r?

You may have wrong turbine housing on your turbo. A picture of the turbine housing on your new turbo would help to ID what's wrong.

Mine fit perfectly with both the tomei dumps and stock dumps.

The oil return holes have to be reamed inward to work same as mine

It's possible you bought the wrong turbos. the GTS using a different exhaust housing than the compact 5 bolt used on a GTR. It's been known that people buy the cheaper turbos but get stuck with the wrong housings... the only mod I needed to do was the oil return and oil feed reducer.

Are they .63 a/r?

I have the .82ar.

[NismoS-tune]

turbine A/R should be .64 however there is an option for larger A/R.

[speedracer1610]

problem is i had the wrong ar hot housing. fixed.

.82 AR will make your car very laggy. I would do max .64 on stock displacement. And you probably got the ones that are meant for SR20.
