I had a potential buyer of my car ask what turbos they were, trim A/R etc..
My only answer was gt28r's. with a .86 A/R
Are they off the shelf turbos or does JWT modify them? They werent much help when I asked them.

ok, I know the R is for ball bearings but what does the S indicate? So does that mean the 700BB is a off the shelf gt28RS with a .86 AR?? If so that is great because JWT wants $1500 for one where as I can get one from anyone else for around $1100

There are some pics posted on this site - look for a thread with 700bb in the subject line. There is nothing that says "JWT" on it as far as I can tell (but it is hard to see once installed). Of course it could have been modified by Garrett for JWT... Unless you put a 700bb right next to a GT28RS, it may be hard to know for sure.

Regardless, here is the OTS GT28RS turbo:

And you can clearly see that at least the compressor flange is different from that turbo and the one JWT sells (pg. 7): http://www.jimwolftechnology.com/wol...08-17-2005.pdf
I do know guys who have bought OTS GT28RS turbos for their 300ZX TTs instead of buying from JWT, but they had custom intercooler piping (plus these cars came TT from the factory).

I have been searching all morning, The best I can come up with is that it is a gt2860R with an .86 housing. I know the housing is right because I can see that number on my turbos. It would be nice if they would just tell people what it is.......The car has over $14k in their products on it!

I would have thought a dealer would have chimed in by now with some inside info. I did find this though The 700bb are 76trim, .86 A/R gt28RS So I wonder how its been modded or if it has been modded?????

So what is the 850bb then...a GT2871RS?
Look here:

you can buy the GT28RS (GT2860RS) from these guys with lots of different housing options.

The 850bb is called a GT-30 I am not sure the ins & outs but I think its a GT-28 frame stuffed with larger wheels????
If you really want to know the exact details email JWT tech support or call them they are very helpful. I have even got emails from and spoke on the phone with Jim himself. Make sure you have some free time on your hands if you get Jim on the phone....he is very helpful but he likes to talk

At the bottom it says JWT kit uses GT-25, GT 28 and GT-30 turbos but it dosent have any specs. On the turbos page they have more specs but not for the G/Z kit turbos?
