Great looking kit Sean. I'm almost sorry I wasn't more patient.
That said, I'm thrilled with my A-Spec GT40R kit.

So it had to wait till this turbine setup was finally in my hands. When your ready we will take care of you if you wanna upgrade.
Are you guys taking about it being inverted or that the WG exhaust flows in a relatively strait line to the DP? What is the benefit of this?

I was wanting to get the wastegate away from the DP and tranny for awhile. There is just a lot of heat right in that area. Gene called here awhile back and was working on the same plan. I just couldn't work it into the shorter manifold so it had to wait. Just less stress on the wastegate thats all and yeah it allows for a better aproach angle into the DP as well.

Nice work though, it's good to see a company that actually does solid engineering and makes a quality product.....seems like those companies are getting rare these days. Please keep up the good work, I won't be stuck in this state forever and I'll need a single kit at some point....

can someone help a newb out and explain the benefit of this design over what is currently used?
its much easier then me making some misinformed guesses.
cheers

Turbo comes V-banded. The benefits of the kit were explained above. It has optimum runner length and is equal in length. It runs fully divided, the thought behind it is no cross talk between runners, as well as allowing you to run a larger turbine housing and still get the same response as a smaller one which equates to a broader powerband. ie. more flow up top but still quick spool of smaller turbine housing. Hope that helps.

So is the v-band 3" or 3.5" ? What size is your downpipe ?
I know you make quality manifold, just wondering what size v-band the turbo has. I've already gotten my T4 manifold and am looking to buy the turbo only. But now after seeing the pics, I may just as well buy the whole kit. Still considering...

GT35 and GT35R have different compressors.
For comparison:
GT35:
wheel dia=76
trim=52
A/R=.50
GT35R:
wheel dia=82
trim=56
A/R=.70
You can also buy a GT35R compressor without a ball bearing center section-I have been running this setup for about a year now and am very happy with it. Therefore, 'R' does not refer simply to the center section type.

You can buy just about any combo of wheels, however Garrett uses the "R" to refer to BB. I can get you a wheel diameter of 88 on a GT35R if you were interested but it wouldn't be ideal.
The first two positions are always GT.
Position “X” is used to indicate a revision to an original “GT” series turbocharger. The original GT turbocharger will never use position “X”, only in revisions thereafter.
Position “aa” designate the turbine size and bearing system. “GTaa” is referred to as the “Base Model Number”.
Position “bb” designate the compressor wheel diameter in millimeters. Compressor wheels with diameters larger than 100 millimeters only the last two digits will be used.
Positions “cccc” may be used to designate special features of a particular turbocharger.
Not all four positions are required to be used.
Some of these designators are as follows:
“B” Boreless
“D” Dual Passage Bypass (Wastegate)
“F” Carbon Seal (Compressor Side)
“G” Compressor Recirculation Valve
“L” Water Cooled Center Housing
“N” Ported Shroud Compressor
“R” Ball Bearing
“S” Single Passage Bypass (Wastegate)
“V” Muti Vane Variable Geometry Turbine
“W” Water Cooled Turbine Housing
There are some exeptions but very few. Usually when the sizes or designators don't match up it means something has been either made purposely(ie optioned) that way or rebuilt with what was available. Hope that was informative to someone.
