2.9 Turbo Project

[PetroleumJunkie412]

I run the merkur upper on mine - is better than ranger one. Linkage is hard to come by, though.

Theres three types of lower as well - standard, high strength, and merkur. Merkur has extra coolant ports.

Timing on dohc is 2.4 meter chain iirc. Good luck lol

3g alternator is worth it.

I forget why I didn't go with the mr2 pump... I think it was availability. Epas conversion on mine was somewhere around $150 all in.

I have two merkur uppers, one is on my Scorpio lol. And screw that linkage, I just made a bracket that accepts the bare cable after I trim the end off of it to expose it. Still need to figure out the ratio between the pedal and the throttle, but it should be easy to just adjust it on the manifold end. And what is this 3G alternator I keep reading about? Like what applications were they on? I was just gonna buy one for a mustang from jegs or something and wire up the exciter and the charge warning light to it, but apparently this 3G is a better fit.

Mine came off a Windstar van with a 3.8. I think.

Bigger alternator that adapts easily.

Finally, something went wrong. Head gaskets blew. And it wasn't even from boost. Someone in the past couldn't keep half-decent coolant in it, corroded the compression rings and started consuming coolant and putting combustion gases into the cooling system.

In the process of doing it, I pulled the timing cover to replace the chain & guide set and pulled the cam & lifters to inspect everything, all seemed well. However since this engine has been apart before (fel-pro head gaskets coming off) I can't tell which way the cam retainer plate is installed. It clearly has a path for oil to flow, but the plate covers two galleys, so I don't know which galley gets the path, and which gets covered completely. I also read about installing it upside-down to remedy oil pressure issues. So which way is it? or, does it even really matter? Also, with it being a possible 'bleed point', with oil pressure and no gasket, same with the tensioner & oil pump, would some thin paper gasket material help at all with any bleeding? Or is it best that I don't bother, and just put it back together as it came apart... No issues before, I can't imagine any that could develop, at least in the near future.

Might be able to use a universal trigger wheel?

If I had a lathe, yea. Pretty easily, actually. I'd have send-cut-send make one with a certain id & od and turn a face onto the back of the damper to locate it and then weld it on. Hell, I'd start making them and produce a kit to convert a 2.9 to eec-V, using a 4.0 cam sensor. Would make a 2.9 run super smooth.

I'm assuming you're using EDIS6, hence the lack of need for a cam sensor. I actually used stinger performance's cam trigger. Pops onto the factory distributor and works well with my microsquirt. Reason I used it is because Im too lazy to fabricate an entire serpentine belt setup just to use the 4.0 damper. Good to know that they will drop in place of eachother, though. Means if I want to convert to a 4.0 in the future I can keep the electrical setup identical.

Correct, EDIS-6, so need or use for a cam sensor input. I actually contacted Shannon about building a 36-1 for the distributor rather than the 24-2 that you have. He indicated that it would need to be too heavy and he wasn't comfortable with slinging that much weight around. It might work fine, but he didn't want to risk finding out the point at which it might fail and be sent flying.

I'm staying v-belt, and yes, that made this more challenging. What solved it for me is when I found someone who abandoned this project... (I now own the important bits)

Did someone machine teeth into a factory damper?

And a 36-1 wheel at camshaft speed wouldn't work for EDIS. It needs to be crank-mounted

No, the back side was machined a small amount to interference-fit an off-the-shelf (low volume) 36-1 trigger ring. There's a few different vendors that fabricate them such as this one...

Ah, right. I never got far enough along with that idea to even consider that it wouldn't have worked!
