Hey all,

Was wondering if any GTR yodas could she'd some light on the subject. Bought a GTR recently and was told the car had upgraded garrets but not sure on size.

Pretty tightly packed on the exhaust side of the gtr as you guys know. I need someone to help me identify what it is I have on the car.

What I do know:

- They have a .64 rear

- has Garrett on the front covers

- noticed a tag that says ARMS on the front cover. Can't see much but on the tag it also says RB and an A engraved/stamped under it. Reallllly tricky to try and get a pic.

Anywhere else I should be looking?

Thanks in advance

again without seeing the tag we cant say that these are your turbos as alot of very different turbos look very similar

thanks man...

did some digging and found this...

Tomei B7655 (173011) 47.7 55T 0.42 T25 T25 47.0 76T 0.64 BB ~500PS

looks like i will have to remove some stuff to get to the tags to confirm..

Seems as though they are Tomei variants. not finding a lot of info on it. car makes 260kw atw at about 14-15psi. stock ecu.....

If they are Tomei.

Commiserations... Just search "ARMS" here on the forums and you'll see they are not the best performing twin configuration, they are almost the worst. They are better than factory though in that they wont break. So that's good news :)

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
