Project: XP Stealth

I wanna see this thing in action again next year.

One bad ass car!

:). I can't wait!

So, I got un-lazy today and pulled the trans out. I have acquired the slightly hard to find JDM 6 speed front ring and pinion, and a 6 speed transfer case. Now I need to make them fit my 5 speed trans. I still need to get the front piece of a 6 speed drive shaft, but that's for later.

Sweet!

OK, I've made a bit of progress on this.

The spacer for the front ring gear has been made and is in place. The bell-housing and T-case have been clearanced to get them to fit up. And the extra material has been welded in for moving the two bolt holes. I need to flatten those two areas out and then drill and tap. After that the gearing project is done. Most of the credit goes to John on this.

I have also picked up a new Kirkey race seat and an FPR. I'm not sure when the FPR will get installed, but now I have it.

No shout out/pics... More cone dodging grip before more OMG hp/Tq is made.

Kirkey's ftw!

Too bad this car isn't a foot or two narrower as to help reduce the cone carnage. Sure makes me want to get some R-compounds to further dominate Street Modified, though.

OK, a little more progress. I drilled and taped the new holes to bolt the t-case to today. So now it's basically just re-assembly and a few other "simple" mods. Simple is easy to say when you have help from John though.

Ok, the gearing modification is almost done! All I need to do is put the trans back in the car. As far as I know this will be the second 3S to have this modification done to it. So here are some pics of the work:

A bit of grinding on the 6 speed t-case, makes for less grinding on the transmission.

A nice close fit

Not particularly useful with out before and after pics, but shows the contour that is need to fit the 6 speed t-case on the 5speed trans. Stock the webs are close to flat between the top and bottom.

A sharp eye will notice the top left and bottom center bolt holes have weld around them. Material has been added and the holes moved about 1/4 to 3/8" to properly line up with the 6 speed transfer case.

That stuff, along with a new front ring and pinion, a spacer and a slightly longer drive shaft and the you have the shortest possible gearing for a 3S. If you are wondering why all this is necessary, it's because the 5 speed and 6 speed t-case's have significantly different ratios. The rear diff ratio and t-case ratio need to work out to be the same as the front ratio. And as mentioned earlier, there is no alternate gearing available for the 5 speed. I could have swapped in a 6 speed, but they come with their own set of problems, like $$$ and they are a little weaker.

Other mods started over the winter and to be finished are a nice new Kirkey seat, 5 point harness and a couple of mufflers to be installed.

A big thanks to John for all the help!
