LS into 1987 EXMOD 110

[Boswalt]

I would suspect many other non Rover people have put NV4500s behinds LS engines and have figured out the exhaust.

Problem is the position of the engine doesn't allow clearance for the exhaust on the drivers side as it's very close to the frame. The one solution that works well for the automatic transmission folks is the hooker setup nick recommends but with our external slave, it doesn't work.

I looked at internal slaves and if I had a later nv4500 that might be an option but the earlier models look like they'd require some heavy machining (meaning more that I can do) to get that to work.

That leaves me with exhaust manifolds and I found one set that appears to have the exit flange near the third cylinder on each side and above the frame. This should give me the clearance I need. I'll let you guys know in a couple weeks when I get back from vacation.

So there isn’t a hydraulic throw out bearing that will work? I would think these would fit most applications.

While some of the OEM hydraulics won't work, or won't work without a lot of fiddling about, I'd be surprised if one of the McLeod bearings can't be made to work. I've used them in a number of cars and their ability to be built to just about any length, or support any style bearing face makes them attractive.

The McLeod site really is a mess, despite it's good looks. I highly recommend calling them and talking to them about a solution. They can do much more than their site shows. Heck, about half the parts we use of theirs are "custom" or built just to our specs.

If a Mcleod bearing won't work, Tilton also makes a nice hydraulic TOB.

I agree with Jason. With stuff like this it pays to pick up the phone and talk to the techs instead of Googling. I had McLeod make some custom multi plate drag racing clutches for Nissan Patrol and Land Cruiser a few years ago for a client. Nice stuff, nice people.

Patriot makes a header set called: tight tuck. Maybe?

I looked at every header option I could find, lots of discussion with Nick too and nothing would appear to fit on the drivers side due to the frame rail limitations. If you can get headers sent on a sale/return basis maybe you'll find some that'll fit but I can see the shipping costs soon out weighing the extra for a performance internal slave, then just use the hooker headers.

Or just make some out of black pipe & weld-ells like I did

BTW, I had to shorten the passenger side vertical section 1.5" to clear my 3rd as I made it a bit long

PS... don't let the wife catch you baking on EHT paint in the oven whilst she's out getting groceries

We got the engine, transmission and t-case mocked up in the 110 and the LT230 will sit in its original location. With the mounting holes on the left side of Nick's adapter we will have to fabricate a mounting bracket but it should bolt right up to the original frame holes.

Linkage and shifters (D1) are hooked up and there is no interference. The only place we had to carve was the right side transmission mount on the transmission extension to clear the LT230 snout. I'll have to pull the t-case to get to the diff lock inspection plate but we knew that going in.


Tunnel will have to be modified slightly but things are lining up.

Still waiting on the new headers then we will get that sorted out. I'll go through the pics and post soon.

 

[Boswalt]

Engine is in. Everything fits with a small amount of fabrication and modification. Still lots to do, drivers side exhaust manifold being the biggest issue but it?s getting closer.

Few more

Looking good!

Looking fantastic—very exciting. Header clearance was an issue for me (all of us...) too. It looks like from the photo that cylinder 8 actually fires slightly upstream. Maybe just the photo, but if so, you may want to tweak that more downstream as it can cause back pressure and heat issues at union and won’t do you any favors maximizing engine capabilities...

What pic are you referring to? Not sure what you mean by upstream.

 

[MountainD]

This one. Header on left, lowest down pipe. If it was on truck, 8th cylinder. I was told you want at least small angle (ideally large one) in the direction of travel. To me, in the pic, it is slightly angled more toward the cylinder head than the muffler end which I was told is a no-no. Just what I was always told. Sometimes you almost have to do a 90 T, but I was told never angle upstream. But I am not a header designer-maybe it’s no big deal. Now would be the time to check though-with the access easier before things are buttoned up. If not a big deal, then great- if you (or someone else) knows it’s cool to do it then sweet- I will happily learn something! I,ve only helped on some, never designed any...

 

[Red90]

It is fine. You don't know what you are talking about.

 

[MountainD]

Cool— like I said, not an expert just passing on what I was told which is why I qualified it exactly as such. Anecdotally interesting how wrong I was when I look at other designs: https://www.google.com/search?q=exh..._4TZAhVJw2MKHenPA0oQ_AUIEigC&biw=1024&bih=666

My intentions were nothing but good.

 

[Boswalt]

That?s Andy?s Home built setup, not mine, but that guy knows his stuff and appears to do his homework.

Don?t sweat chiming in though, I appreciate everyone?s input

Ignore Red90, he only likes diesels !

There not perfect, but will do for crawling around the BC bush

Getting closer

I will admit to a moment of nervousness when I saw the diesel filter still attached to the firewall. Also, I would tuck that air filter into the front of the wheel well. I got some good advice on getting it away from and in front of the exhaust manifold which I did.

 

[Boswalt]

Yea, still some plumbing issues. The diesel filter is a leftover basically just holding the lines out of the way until we tackle the fuel system. The air cleaner presents a few issues, I was hoping to get it under the right wing vent and use a scoop to pull cold air down since my heater doesn’t plug it.
