SC DIS on 3.8?

Well it seems no one wants to buy my 90sc engine so I think I'll stroke the block keeping the forged crank and using longer rods with .030 over pistons. And I was thinking...Looking at ranchers IC tubes and how the route right through where my distributor is. I'm thinking about swapping to DIS. Is it possible to swap over all the DIS stuff and just get a custom burnt chip or are the pinouts completely different? If I have to make a custom EEC harness or swap harnesses or anything I'll just figure out the difficult way to route IC tubes. But if it's easily achievable then I'll attempt it. Plus the idea of computer adjustable timing excites me

I'm pretty certain it's possible for your application, but I'll see if I can take a look at the EEC pinouts tomorrow (it's almost 4AM, and I've been up for 3 days straight for finals, so I probably shouldn't look at a wiring diagram now anyway). I installed DIS on my 94 LX when I did the splitport swap. I had to repin/add a few wires at the EEC connector, and I used a the DIS module, cam sensor, and crank sensor from a 94 SC with a 94 California Emissions EEC (though a 94 SC EEC would have worked). The part that was a pain was making a wiring harness for it all.

I've got a feeling that the supercoupe lower intake would work quite well with a vortech supercharger.

The 97 NA 3.8 have DIS factory. They also have the newer EECV.

Maybe you can find thoes parts and use them.

I thought all SC's had DIS?

all sc's do hav DIS.

Rod, thanks for the help. If I have to do what you did then it's not worth it, your dad told me what a pain it was do make the harness and add wires.

Rancher, It'd be interesting to use an sc lower, but you'd have to make a pretty custom upper intake to match it. Using the sc lower and the right custom upper could allow for room on the top of the front of the engine bay and I could route a tube right over the engine...I wonder if that'd work. Then I wouldn't need DIS at all.

So let me know what you find out Rod, thanks.

Thomas - if no one is interested in your SC engine, why not use it to make up your parts. With an SC engine, you've got a strong block and it's already supercharged... what more could you ask for

Yeah but I've heard of the troubles of swapping in an sc engine

Besides, I'm trying to stay as original as I can and go the route I really want to. I'm considering going turbo now with Dirtybird having a kit made for our cars and all. I'd love to have a tbird that shifts at 6500rpm and makes 400rwhp or more. But I'll probably end up using the block and crank to build my forged stroked longblock with the cam I have in the mail and ported heads that are coming soon.

I didn't mean using the entire engine. I know the SC block is stronger, but aren't they the same in basic shape and everything?

well the block is essentially the same, but the crank and main bearing are what I'm after. forged crank and bigger main bearing.

Thomas,

I made up a quick wiring diagram describing exactly what you'll need to do. I can email it to you if you want. Just shoot me an email at [email protected].

You'll need to add a total of 4 wires. Two of those wires need to be added to the EEC connector. The rest of the wires can be spliced into or used from the distributor and old ignition control module.

It will take a fair amount of wiring, but it wouldn't be to difficult to do. The bigger pain will be getting the EEC, cam sensor, crank sensor, coil pack, and DIS module that you'll need.

well I've got the motor out of the car so everything will be easier to work on. And the front accessory brackets are off too so that parts already done and out of the way. I know everything on your list rod, except for the cam and crank sensors, could you describe to me where they are exactly?

When I swap those sensors over, will the holes for the sensors be there? Or will I have to swap the sc block also? Cause I'll probably be doing that if and when I stroke the sc block.

The cam sensor is located in the same place that the distributor is on your engine. It will bolt right into your engine, using the hole from the distributor. The crank sensor is a small sensor that should be bolted to your timing chain cover. You may have to change timing chain covers to get it to bolt up. You'll also need a harmonic balancer with the "flying magnet" sprocket on it. Look at the SC's HB and you'll see a sprocket-like piece at the back of it. The crank sensor basically receives a signal from it, which tells the crank sensor the position of the crankshaft. I don't know if you can just bolt that sprocket to your harmonic balancer, but I do know that later 3.8L N/A's definitely had them.

Here's some food for thought.

Vortech makes all sorts of wet Intercooler set ups. I'm thinking of doing some talking with those folks to see if they have something that replaces the Super Coupe IC.

I also have a SC motor sitting. I may just overhaul the sucker and modify it for implant into a LX, THEN LOOK THE "F" OUT!

The Parts Bin Special is DEAD! It is being parted out.
