msd ignition

[carlosz]

I have posted on two more sites, waiting for repply but here it goes, has anyone installed an msd ignition system on their rover, if so let me know your experiences, pros and cons.....
thanks.

I installed a 6a on my classic. It was fantastic. I wrote a small article about it on rangerovers.net

I was on my way to doing so... I installed MSD wires and a blaster coil. Never quite made it to the actual 6a unit. I still have it in the box though...

Where did you put the 6a? That was biggest problem I had and why I never finished the install.

thanks, I am thinking about 6a or 6al with a blaster ss , iam thinking of stashing the module under the dash since it is not water proof and I off road lot. I could go with the marine version but that is a lot of money.

That's probably not a bad idea. I'm not sure why I never considered that... maybe I was looking for a quick install and pulling all those wires didn't appeal to me at the time. But, given how crowded the engine compartment is, it may not be a bad idea. Would heat dissipation be an issue?

On the performance ignition thread... I was searching around ebay the other day and saw someone selling a DUI performance ignition... everything is in the distributor. Anyone familiar with those?

I have heard of DUI also I have looked at their website it looks like a customized GM distribuitor, I have various of those at home in my shop, I have thought about the custom work needed to make one of those work in a rover, it is a HEI system, high intensity discharge with everything built in
(coil, module, capacitor, etc.) I don't see why it would not work on a rover when it has a hotter spark and it would make a more eficient engine.
my personal problem is that i offroad in swamps and lots of river crossings that being said the distribuitor is mounted behind the fan so it showers the dist with all the water and mud, so failure is emminent, also the size of the gm cap is almost twice the size of a rover so wedging it behind the alt may present a challenge.
on older rovers with the 3.5 engine the dist drives the oil pump, 3.9 engines and above do not have this later problem as the pump is driven by the crank,that said and solved it should be a very efficient ideal system, definitively better than the factory primary ignition system and something were parts could be found very inexpensive at any local parts store, even pep boys and advance. also gm is very upgrade friendly.

as for hiding the MSD module behind the dash there is a hollow area where air circulates for the center vents, so it should allways be cool and if you move the recirc lever to fresh air you can get ram air from outside or fan air if the fan is on. regardless of temperature position you get fresh air allways.
go for a drive and fiddle with the levers and you will find out what i mean.

I bought a DUI a few years back and it wouldn't fit short of shaving a good bit off the left front ear of the intake. I got a bit of a run around from them. They did give me my money back but I really resented the fact that they sold me a part that stood no chance of fitting properly all the while telling me that they had, literally, sold thousands to Rover owners. That, in and of itself was a lie.

There was someone one this board a couple of years ago who actually had a DUI in his truck. I don't know what he had to do to achieve this. I asked but he never replied. He was selling the truck at the time so I don't think he wanted to reveal what modifications to either the intake or the power steering bracket were necessary. If you visit discoweb.org and do a search you will come up with a good bit of talk about DUI but very little in the way of success.

Rovers North sold DUI for a short while. I spoke with the sales manager awhile back and he said they had to modify the power steering pump bracket to get one in thier DI. Once it was in, between the cost, the fact that it was anything buy a casual DIY install and the less than dramatic improvement in performance, they decided to stop carrying the brand. If memory serves me I believe they were briefly sold by Atlantic British as well.

so my glance at some modification is completely right, as for performance my guess still stands specially being able to upgrade coil and module on a budget... unless complete enminent failure of my current dist. I would not change it, simply upgrade.

I stuck my unit under the Air filter snorkel. Never a problem.

Cant say the truck felt faster or anything, but it did feel different. Smoother idle, little more responce on tip in. The best part though was the field servicablity of it. If I was stuck in who knows where, Its much easier to get MSD parts then Lucas.... PLUS! It could be argued the MSD was more reliable.

Good article. That was my optional placement... the secondary battery tray. That seemed to work ok except the rewiring over to the battery for the + wire. I'll probably try to do it over the winter. I don't recall the MSD as ever giving me much "performance" improvement... I've had my 6a installed in a chevy pickup and it ran the same... like you said, maybe it idled a little smoother. I have the timing control too and maybe I'll play around with that.
