I was reading a thread in the evo forums by the AMS guys talking bout their new "GT37R" turbo kit. The GT37R is a term they made up and they will not release the specs on the turbo. Has anyone actually seen this turbo and spec'd it out? They say it looks physically the same as a GT35R. Could it be a GT35R with the larger 1.02AR for added exhaust flow? Or a version of the GT40R? this would be interesting to find out.

Garrett actually makes a gt37, but according to thier site it does not come in the bb variety only in the journal bearing. I'm not sure what the AMS gt37r is but if I were to guess it would be a gt35r hot side with a gt37 comp. side. That is just a guess however, so take it with a grain of salt.

It runs a larger compressor wheel (most likely a t67or 4088 compressor) and a different turbine wheel than the 35r. The one they tested was teh same .63 t3 housing.

67mm/ptrim/63-5bolt pte.

so this is a garrett turbo version from Precision. ya there is no gt37r from garrett. my other assumption was Precision. Are you 100% on those specs?

i was just looking on PTE's website and found a turbo with those spec. PT-67 its called. but the bearing system used is a 360deg race bearing not a dual ball bearing

I sriously doubt it is a P trim. The P trim is know to be laggy. I have a pt67/ P trim. The AMS is a custom turbo they have made, not something you can order straight from precision. They actually call it the AMS 37r. From what I have read, there is a chance it is a t350/gt37 turbine wheel but they don't want to divulge the info for obvious reasons.

Not a guess. The specs where leaked by PTE.

I seriously doubt that AMS builds their own CHRA's. Its outsourced for sure. But at any rate it would be interesting to know for sure whats the deal with it.

..and where is said information....
You can pick up a DBB pt67/ptrim for 8-900 bucks instead of the 1500 AMS is asking for the turbo intself. Seems kinda foolish on somehting that is as easy as turbo wheels to discover to try to make that big of a profit and piss people off.
glenneclipsegsx-I never said they made it. I said they had it made.

I need to compliment you on your complete lack of including that fact that AMS is the one making the investment into the dyno time to test this setup. As far as I'm concerned, the price of the turbo is nothing but justified. I wonder how long it will take for some clowns to copy AMS' work, rebadged it, and undercut the investment that AMS has made by selling the turbo at a lower price.

If it is indeed a BB pt67/p trim, they were available before AMS anounced any testing or a new turbo. I know Martin has been working on a different combo for a few years, and with Garrett now coming out with a wider variety of BB chra's, its most likely not a coinincidence for this unit to now become available to the public.

My previous post was not to take anything away from AMS, as I think we all have plenty of respect for them. I was just using the arguement to illustrate that it is most likely not your typical BBpt67 /p tirm. If that does turn out to be the case, there is no need to sell the unit for 1500, as the t67/p trim combo certainly didn't see any R+D time from AMS as it has been around for a very long time.

Like he said T-67/P-trim/BB/.63 a/r 5 bolt hotside.
Full-race offeres a T-67/35R combo.

Just point to where it was leaked then and I won't have a problem believing it.

The leak came from talking to PTE on the phone. The turbo is 1350 from PTE and 1400 from AMS. I think it is kinda silly for AMS to call this turbo the 37R. It is a very old very popular combo of wheels that just recently became available in a BB version.

Not realy a big surprice that AMS is just selling a re-labled PTE turbo for more money.(if that is the case)
Buschur has been doing it for several years now.

wooops!!! seems like I started a heated discussion here. But I should of expected it. It is my own damn fault. Hey im an engineer and I like to know the why and how about things. Sorry that I started all this trouble though. But listen gentleman and ladies if there are any in here, AMS is not trying to rip you off. The retail price on this PTE turbo you guys speak of is only 25$!!! less than what AMS markets the 37r as and this is assuming that the the so called 37r is the same turbo. I really didnt mean for this to be a post against AMS as I respect what they do.

.63AR? i doubt it. the GT35R is a .82AR. the .63AR is way restrictive and wont allow the 35R to reach its full potential

750whp has been made on gt35r with .63 hotside. How restrictive is that?

the 35r as been maxed out on a .63ar and .82ar turbine and even a bolton .48 turbine

Im pretty sure ams uses .63ar housing on most of their gt35r set ups. They say that it spools a few hundred rpms quicker and said going to a .82ar they only gained 15 more hp

Where? I dont beleive it. Maybe a car with gt35r/nitrous. A gt35r wont make 750whp no matter what.

the gt35r is out of air by 650whp

Two EVOs on evom made 670whp on the 35r without nitrous. The 750whp was on a 80shot.

You can max out a lot of compressor with a small hotside. You just have to keep turning the boost up. It is definately more restructive than a .82 t3 or a .68 and .81 t4.
