A truly exception looking car. Very nicely put together. I hope it is as much fun on the track as it looks like it will be. Great Job. Erik Johnson Carquip Sales (303) 443-1343 ext 2 work (720) 980-9407 cell

Dear Mike, You basically draw a line across the center of the Pinion shaft, which is essentially the centerline of the axle flanges and place the fill in a location along that line. We typically place it in the center section of the gearbox. I would also recommend installing a transaxle oil...

There were a couple of options for your 924, so it is really going to depend on what year and type of gearbox you have. I would be happy to discuss this with you in more detail. Warmest Regards, Erik Johnson Carquip Sales (303) 443-1343 ext 2 work

Hey there everyone, I just wanted to put a quick post here, to remind everyone, that we specialize in Porsche transaxles, and kits for your builds. We have a very good selection of gearboxes, specialized gear ratio's, as well as other bits and pieces to make your builds go much smoother...

Hey there everyone, I thought that I would chime in here. We specialize in G50 gearboxes for V8 applications. And yes we have a G50/52 currently in stock along with a couple of G50/50 gearboxes. The inversion process is not difficult for those who would like to do it on their own, but...

Hey there Fred, I just replied to you other post with regard to your G50 options. There is one thing that I wanted to make sure you understood with regard to changing out the differential. It is NOT a plug and play option. You will need to ensure that the ring and pinion has been reset...

Well I thought that I would put my .02 cents in here. The ATB or torque biased differential is a great street diff, however, does not lend itself well to the track as there is not lockup on the decel side of the differential. As to changing out the 1st gearset, this can not be easily done...

I am going to highly recommend that you make sure that the inversion process on this gearbox is down completely correct. Meaning that you have new oiling passages drilled into the case to ensure that you get proper oiling. I would highly recommend a cooler and pump, as well. But most...

We recommend the Swepco 210 for the 930, and I would not worry about any kind of LSD additive. I would highly recommend a transaxle cooler and pump though, as heat is going to be the biggest killer, especially with a LSD installed. I would happy to help you with this, should you have any...

If you are in need of a G50, we can certainly help you with your build. We build a great many of the G50 gearboxes and usually offer a taller 4th gearset of 0.96 and 5th gearset of 0.667 to make these a bit better suited for the V8 applications. We have had very good success with this setup...

The G50 is a great gearbox for your application, with the correct modifications, in my opinion. A spray bar is not needed, if you install a good transaxle cooler and pump, which I very much recommend. Heat is the biggest killer of gearboxes running in the inverted position. There are several...

Thanks for the pics, I am going to have to pass on this one. Good luck with the sale though. Erik

Well I thought I chime in here regarding the transaxle options. There are many, and as you have been on the GTM site from time to time you will already know that. Be selective when it comes to who you go with for your transaxle. I say this only due to the fact that the company that you...

Could you post a pic of this gearbox, as well as who did the build on it please. Does this have the OEM LSD in it, or was it upgraded? Thanks for the information. Erik Johnson (303) 443-1343 ext 2 work

That is very often another direction that be explored. While one needs to be somewhat careful as to the quality of a used gear, it is a very viable option. I would recommend that new dogrings be installed prior to purchase though. I can help with that too if anyone is in need. Hope that...

Thanks Jack, Really appreciate that. It was good speaking with you again. Let me know if you need anything, always here to help. Warmest Regards, Erik Johnson Carquip Sales (303) 443-1343 ext 2 work (720) 980-9407 cell

Yes the 4wd LSD is controlled by a push rod mechanism that controls the lockup of the differential. It will not work correctly in a 2wd application. Hope that this helps. Erik Johnson Carquip Sales (303) 443-1343 ext 2 work

Dear Randy, No offense taken, not at all. The reality is that there is what works on paper, and what works in real life. Most of my track time is in a rear engined 911, and prohaps that makes things work somewhat differently, but the concepts are still the same. A Torque Biased...
