Not to mention you could have tap up and tap down shifting.

Ok so picture pulling up to a new GWagon and giving it a run for its money... while you leave the jeep crowd behind.

2nd gear: 2.363:1 1.48:1
3rd gear : 1.532:1 1.00:1
4th gear: 1.152:1 .73:1
5th gear: .852:1
6th gear: .667:1

As you can see, gears 2-5 are similar to the ZF but you get the offroad low range 4:1 1st gear and the highway friendly 6th. Plus the low first gear allows you to cheat the rover axles and run a higher differential gear ratio and pick up the added strength of a decreased tooth count on the ring gear. As for durability, a few are running these transmissions in King of the Hammers and they hold up pretty well.

One tip when looking for an engine: Make your life easier and buy an engine, transmission and ecu all from the same vehicle. The 6l80 has a reputation for being difficult to re-flash if you mix and match (i.e. corvette engine and truck trans.)

Gen IV running

Gen IV running. Nice - no exhaust other than the headers hooked up. If you listen toward the end of the video you can hear the engine to into 4 cylinder mode i.e. listen for the change in the exhaust tone. No accessories belt on the front.

Wow! Sounds brutal (which is a good thing :D ) Very nice job. I am sure you guys are pretty psyched to get to this point. Can't wait to hear what you think after the first test drive.

Gen IV running

Sorry guys I should have signed in under my account when I posted the video of Nick's 90 running. Hopefully this didn't come across as gratuituos self promotion. I happened to be over a Nick's yesterday working on a project. That is my voice (which sounds like a 12 year old's) on the video.

O.. and the project I was working on at Nicks

Just a little engine swap. I can do more of a write up with pictures on it. This is Nick's previous LS Gen 3 mated to a 4 speed and BW T case that will be going into the Banana mobile. We took the 3.9/R380/LT230 out in one shot.

I still have a long way to go but I had a very satisfying day today!

I guess some poor planning on my part means I will be in Vietnam the week of the rally. But I'm looking forward to some CO wheeling this summer.

Please tell me this thing isn't going to have huge wheels on it and an absurd two tone paint job. There still needs to be some purists out there.

It will be in a NAS 110.
Well... it will not be white (it will be Willow Green), but it will have 16" rims and be all one color if that helps.

To help Nick we are going to post detail images, part numbers of what we use and show it in all phases. The hope is that it will help Nick sell set ups so people can do it themselves.

It does. I can't get behind these conversions but at least you aren't bastardizing the looks.

I tend to agree, but as much as I love Rover stuff it is hard to argue with the package. For this project we just bought a brand new (complete) LS3 and a brand new 6L80E with all the wiring, the ECUs, a custom set up in the gearbox ECU so that it works the way we want it, etc. etc. and all in we are under $13K shipped to our loading dock.
That may sound like a lot (considering you could junk yard a lot of that for cheap), but try putting together a brand new performance 4.6 Rover V8, adding in the cost of a new ZF auto and all new ancillaries and it is way more than that and you are going to be at about 275hp vs. over 400hp. It isn't for everyone, but IMO it has a place in the market.

Barry. You need to drive one. You'll get behind it once you drive one.

They are factory original garage art to him. If he drives them, they go down in value.

So with that setup and an LT230 (as I want to keep my 1.667:1 ratio) instead of the BW.... and the transfer case on it's standard mounts, how much further forward is the engine... ie, is there room for the rad with electric fans up front ?

Easier for me to find the older gen 3 & 4 speed here than the newer gen 4 setup.... and for a 90% trail truck I'm not too bothered about economy on the highway...
