Can I ask what you paid for the lot?

Nick,

It looks like you reversed the intake manifold on the one in the 90 is this required or just something you did to get the throttle body out of the way?

From what I have read it is really really easy to do and the only issue some people run into is with the oil pressure sender. Did you have to modify / change the oil pressure sender?

I hope I can pull it off, I spent and hour on the phone with Nick before I was 100% sure I was going to give it a go and he seems like a nice guy that is willing to make it happen. Not something I could do on my own at this point but with Nicks help it sounds like it will happen. We will see if I stepped up or stepped in it

For people asking about the cost of the lift out motor package it was right about 4K shipped. there were others for less that had higher miles and I am sure if I waited around I could have found one for less but I really want to have my 90 on the road for the Rally in Sept so I have to get the process started.

.
you can shave it off, and get someone to tig weld it closed as long as you don't want the sender.

$4k shipped doesn't seem bad. It would probably cost you that much to gain the HP (not to mention fuel efficiency) from a Rover V8. Looking forward to hearing/seeing more of your project!

The intake was reversed for a couple reasons. The hood won't close and hits the throttle body. Having the throttle body in the back gets it out of the hot air and facilitates the air filter fitment.

I didn't have to modify the sender. I test fitted both the truck intake and the Camaro intake. Neither interfered with the sender.

Another part sourced

For this swap you need to buy the hi/ lo - CDL mounting plate from an automatic 1994 - 1998 Discovery series I. this is where your CDL attaches and the plate for the shifter. I suppose if you have a 1997 with an automatic you might not need this part?

They are pretty pricey if you buy one new online ~ $120 so I opted to go to the local pull and pay and got one for $9.

Here is a picture for future reference (lifted from Ashcroft where they sell for 60 GBP).

Question for you Nick. Are the 4 holes in your Adapter in the same location as the automatic Discovery transmission? From looking at both it seems so but just wondering if you kept the exact same location.

Really looking forward to seeing what you come up with Mike. I am planning to go with the NAS style console as well so hopefully I can learn a few things from you along the way.

Ok so I have read through the thread, and you all have probably done way more research than I have on this, why not develop an adapter for a GM diesel? Too heavy? All show and no go? Torque blow apart an LT-230?

There are similar companies producing stand alone harnesses for GM diesel engines...

I apologize in advance if this has been covered but I think I have read (and drooled all over myself) through all posts here

There are a lot of people running around with GM 6.2 and 6.5 diesels.

Yes, I have seen some of those conversions, but the new gen of diesel engines, the 6.6L with the VNT turbo chargers get much better economy 2007+
perhaps the engines weight it a little too much I think pushing the scales at 860#s+ with an allison transmission to match.

Just talking out loud here as the kit looks to be of very good quality and a new gen diesel would return some fantastic MPG in a defender

Yes. This locates the transfer case shifter is the stock position. (Same as '97 D90 & D1 ZF)

I'm pretty sure those engines are much too large (physically) compared to a small block that is being used here and the small size of the 6.2/6.5.

I helped Ryan S. stuff one of those into his NAS 110 back in 2001. That engine is the same size as a big block Chevy. Too big in my opinion. The passenger toe box had to be clipped to clear the exhaust, the bonnet had to be gutted to close, the radiator had to be moved forward,... He ended up trading it out for a 2.8L.

Id be more worried about weight for those who traverse mud and/or snow. Your front end would sink to China.

On the rear RH side of the transmission adapter you have to cut off a portion of the factory mount so it will clear the transfer case it took about 5 mins with a sawzall. Here is how I did it not sure if this is where Nick recommends cutting them but it seemed like a natural place and similar to the pic he sent me. You will see a little casting nub on each end and it puts you right at the edge of the hole. An initial test fit shows that it clears now.

Shifters

I received some questions regarding other shifter options. It all comes down to the tap-shift issue. All GM vehicles (that I know of) have the tap-up/tap-down switch connected to the BCM (body control module). Which communicates to the TCM (transmission control module) over the low speed CAN bus. Since there is no BCM in this and most conversions, it presents a problem. Luckily, the Corvette didn't have a BCM either. GM used pin 7 on the TCU for a switch directly wired to the transmissions. Thereby not needing a BCM. This "pin 7" is what we use on this conversion. This is one of the configuration changes in the TCU setup. Use pin 7 for the tap-switch.

The shifter that SpearTech sells has been modified to use "pin 7" on the TCU and not the BCM. For my Lokar setup, SpearTech provides a tap-switch ($150) you can mount anywhere. Either way, the tap-switch wiring option is required when ordering the SpearTech harness rework.

These guys have a pretty cool tap shift kit they are using in JK/LS conversions. http://www.lswrangler.com/cruise-con...tap-shift.html

Here is video of their cruize control and tap up tap down. Pretty cool.
