Hop on eBay. I think I saw .96/.81/.68. I didn't see the 1.25 like the real VSR stuff.

I did. And you knew what I was looking for lol.

what unit is the one on the bottom?

Top is GT67 fr the STS kit, then the billet 7665 from VSR, then the eBay billet 7875. Kind of cool to see them side by side and get to test how each of them act on the same setup.

I would actually measure them.

The GT67 and the 7665 had essentially the same turbine wheel just a different AR and obviously a bigger compressor side on the 7665. The 7875 I believe someone on here already posted measurements on. The 7665 was good for about another 100 hp over the GT67 for me.

The 7875 is awesome!!! Car feels like it picked WAY, saw 13 psi in 3rd. Doesn't feel laggy at all once it's lit. Need to fix an oil leak on the feed side. Wondering if I have the wrong fitting size.

Good to hear. I've always like the way turbos sound in rear mount cars too. Get some videos.

Most people come to find that a properly sized turbine isn't much if any laggier then an undersized one. I have a 102/112 wheel on a 5.3 and can roll into the throttle at 2K RPM and have boost, much the same way I did with the 75/83 turbine. Difference is the larger turbine breathes even better up top, which you should realize as well moving up 10mm.

Ive been paranoid about it since the turbo's 18ft away from the source lol. It definitely felt like it was still pulling at 7k whereas even the 7665 was out of breath. Back pressure FTL.

is this the 7875 I'm seeing on ebay now for 260ish? how does it fit by the rear end?

ddnspider

Yes, same one on ebay. It was a direct swap for my 7665 without a problem. Only change was the compressor outlet coupler size for me. Otherwise dropped right in.

In other news I discovered last night that I have 4.10 gears. I'm sure that's doing a great job loading it down to light off the turbo

This 7875 is just excellent. The rearmount is giving me just enough boost limit in 1st that I hook up no problem and in higher gears it just wants to keep pulling even at 7k. I'm maxxing the frequency on a 50% scaled LS7 MAF. It would be even crazier if I didn't have 4.10s I imagine. So glad I chanced the $260 on this turbo. And the meth kit is working great too. I managed to get the LED in the center console vent next to the wideband and boost gauges so I can see when it turns on and I have guaranteed flow. Nice that all the bugs are sorted and everything is working right and I get to enjoy the car.

Let me know if you plan on hitting osw any time soon. I still haven’t made it but hoping that changes pretty soon.

I definitely plan to go to horse power wars, but probably in the daily. I do want to see what the "wrong combo" will trap though. I'll holler.

That's good to know. I've been looking at the same turbo on ebay myself.

Updated title of the thread after finding out I have 4.10's and the load discussion vs. gear thread......rear mount turbo, 6 speed manual, 4.10 gears, yeah Project Wrong-Way
