Dropping an LS 5.3 , 4L60 into an 86 D90. Any advise?

------ Follow up post added December 18th, 2017 02:43 PM ------

It looks like Nick Markiw is the tip of the spear on these kits. Anyone have contact info?
You do realize that the 4L60 will require the t'case moving back about 8", for drop in you need to be running a 6L80 or go manual with a NV4500. It's discussed way, way back at the start of this thread... happy reading !

Hi all...
Have anybody done a cold air intake for the rotated truck intake?

Someone here has this sweet 110 and I saved the photo from their intake. So far it is the best idea I have seen and I plan to route mine in a similar manner. Sorry I can't give credit to this truck--I didn't save who here it is but it sweet work...

Do you know where you got the intake tubing?

Also, how you secure it? Weld a tab and bolt to frame?

Plenty of room behind the engine in my build.

That looks great! Does the LS fit in about the same spot as the stock motor in the Defender? My classic looks much tighter to the fire wall

The LS sits significantly farther forward in order for the TC shifter to sit in the stock position. This creates a significant space behind the engine for the intake plumbing or battery. I'm using a 2012 Camaro L99 vs the more typical truck LS which provides a lower intake manifold for hood clearance and the forward facing intake, but does not have as much low rpm torque as the truck intake.

Given the amount of torque even with the lower plenum (based on the torque curves you and I shared) I don't see the lower plenum to be a detractor anymore. The shorter intake distance to the front fender well is pretty compelling and you have a very clean install.

On a separate note, I took my buddy out for a "first ride" to show him and he thought it was a little choppy on acceleration. It was cold out and the tires were also a little wet so I had to explain that the "choppy feel" and the reason we were sliding sideways to the curb (off camber road) was because all 4 tires were spinning, LOL. The thing is a bat out of hell when it wants to be, that is for sure.,..

When I was first thinking about this conversion, I spent a couple months looking for a low mileage truck 4x4 engine/tranny. No luck. Finally, I was talking to Nick and he explained how easy the 2x to 4x conversion is and sells a kit with the seal, plugs and modified 4x tail housing (trimmed to clear the TC). It took less than 20 minutes to convert and most of that was trimming the end of the tranny output shaft. About that time, the 20k mile 2012 Camaro engine/tranny popped up on eBay. It was meant to be!

The WP configuration was ideal for radiator plumbing and allowed a straight shot for the intake plumbing to the right wheel well. Also, four 1 1/2" spacers allow the corvette accessory bracket to be used with a very minor clearance trim to clear the steering box adjuster.

I think you and I both agree that the conversion was a big learning experience, but if we did it again it would take 1/2 the time. Still brings a huge grin to my face each time I drive it!

Hey everyone, having some trouble wiring my vdo speedo. Really my last gauge not working for my ls swap. Itís a non-gps vdo gauge.

I have a disco 1 transfer case with a two wire harness coming out. This is how itís wired.

Black wire from transfer case position 2
Ground from car position 3
Power position 4
Green from transfer case green position 6,8

Speedo has power, but not reading mph or odometer. Any help is appreciated. Thanks

Looks like you tried to wire it up as a hall effect sender. Discos have an inductive sender.

4 - switched power
3 - ground
7 and 8 to the two wires on the sender.

Hopefully you have not fried the sender. 2 sends power to it and straight power across it without a resistor can cook them.

You can do 2 and 8 to the sender, but you need to add a resistor inline to limit the current. FYI, you can get a multi plug connector for the speedo.

GM Gen 4 conversion including LS

Thanks. Well it looks like I fried the sender. I also tried the yellow wire that speartech puts in the harness for the speedo so I can calibrate the it with pulses, but that didnít work either bc the ecu isnít sending me any pulses. Iíll check with nick Monday and see if that was turned off in the flash. Iím not sure why I thought it was a Hall effect sender. Oh well.

Have you calibrated the speedo or manually entered a pulse number? It wonít display a speed until you do.

I tried to calibrate it using the auto method, but it basically gave me the message indicating it wasnít receiving pulses
