My new buggy, and NV4500 - LT230 mating tech

Hi All,

It has been 10 months since I last logged into D-90. Seing the site mostly unchanged was great. I met some really great people here. Some really close friends. I think I ticked a few people off too.

The reason I am back is I wanted to post up a little tech, and if anyone is interested, post up a few pics of my new car. The rover is gone. I sold it to a guy named Mike in Utah. Awesome guy, and absolutely beats the thing to death. Seriously!

I ended up getting into racing fairly heavy. Still just a part timer, and still for fun, but I caught the bug. And I built a new car, but there was one thing I just couldnt let go of, and that was the LT230. I loved the TDi very much, but I just couldn't get the power out of it. Still a perfect weekend warrior motor. But the LT, man, that is a great case. Bigger gears than an Atlas, dual offsets, AL case, all wheel drive for the desert. Man!

So I tried to keep it. Well, if you are putting close to 500HP in front of it, the R380 aint going to cut it. So the logical choice was an NV4500. Well, not logical. The logical choice was a 6L80E or TH400. But SCREW autos. Yes, I destroy them just by looking at them. It's a gift. No, a curse.

Anyway. Anthony Lawson did all the heavy lifting on this. The design, the idea, everything. I was just lucky enough to find him, and have a buddy that owed me a big time favor who happens to have a milling shop. The result is a match made in heaven. Here you guys go. Hope all is well. Cheers



















Almost forgot. Keith at Rovertracks (er Rovingtracks) made this all possible. From the custom shafts, to the custom NV4500 output shaft. All of it. He is brilliant.

I wanted this two years ago in a swap thread, did you replace the transmission out put shaft? What does the coupler look like?

Would like to know how it works out for you.
Would the guys who built it for you consider making more? I'm not interested in going auto and getting a monster 80e when an nv4500 seems perfect.

We did this a little wierd. Anthony and I wanted a beefy output shaft. So we used a 2wd dodge output that was long enough to get into the deep LT gears. We had to use dodge as it was the only one long enough. We then had the output shaft milled to a 32 spline chevy pattern, and had the input gear on the LT EDM'd to match the pattern. So all said and done we have the big dodge diesel with chevy output. The LT had a ton of meat left around the gears to support this.

Now, all the shenanigans are not actually necessary. I think that you could mill the rover spline pattern in without a real worry of breaking it in most applications. I don't think breaking that is a common occurance. But because of the HP and use of my car, bigger was better.

I still have two of the adapters. I made them, and once you have the fixture, program, and cutters, it didn't make sense to make just 2. Let me know if you want one. I had no idea the need but a few people have grabbed one.

That is straight evil looking. Is the hood off a polaris ranger?

So you use a 2wd dodge nv4500 and have the shaft cut down to mate? I would have figured the 2wd version. Ahh the engine possibilities....

Thanks. That is a custom hood I got from SXOR.

You have to use a 2wd shaft, but a 4x4 back end. It sounds complicated, but it's all pretty simple when you do it.

Great to see you checking in on the D90 Source Buck!

Real cool that you decided to use an LT230 on your race buggy. Hope it works out well on the track/courses. Always liked reading your posts. Yeah, I'm sure you ticked some people off but you always had a good reason for your thinking and you could back your posts up.

Thanks to you and Lane/mightymg I went with Keith and his Toyota stuff. I figured if you 2 were happy with his work at the punishment you were putting it up to, then I would be plenty fine. I have almost a year on the rear axle and working on putting the front together now. Keith has always been great to deal with. Wish I had time to get the rig off-road more and really put it to it's paces but I'll save that for when the kids get older and I can wheel more often. Best of luck with the racing :

Buck that looks awesome! and glad to see you're sticking to some Rover roots with the xfer case. Is it running permanently locked?

Your buggy is awesome, but whats with the Razor hood??? Get a rover rad support fabbed up and a real galvy grille on that beast


Any vids of the buggy in action?

Glad to see you back Dave. What engine are you running ? What wheelbase ?
That is a one mighty clean looking adapter- but that's what one would expect from you.

I already am trying out a new prototype. It's selectable with three settings! Locked, unlocked, and time travel! Lol.

Thanks!! It runs open and locked. Open is killer for go fast.

It's not a razor hood, it's a custom SXOR made from lexan. I honestly thought about putting a d90 hood on it, but there is just no way. The cab is so far forword, that the room is very tight under there. My pedals almost touch the winch. There are vids but I haven't loaded them yet. Cheers!

Thanks. It's an LQ9 with a mild cam. Wheelbase is 114.
