    Hello everybody

    I own a 1982 Mercury LN7 which has been conoverted to fuel injection using a 1989 Ford Escort GT 1.9 HO engine. Yesterday I purchased a megasquirt with the V3.0 board and the person who will build it asked me if I wanted to keep my distribitor or use a crank trigger. Now I am sure that the 91-96 1.9's have a crank trigger setup already. My question is,

    Can I use the 91-96 crankshaft pulley with the crank trigger ring on my 89 escort block's crankshaft? If not,could I use the 91-96 crankshaft in my 89 block and adapt the oil filter housing and cranksensor setup? If any body has another solution please let me know, he is expecting my decision so he can get started on the build, and I could get my LN7 turbocharged and running. Thanks!

    I hopefully I read everything correctly. Here it goes.

    Yes the 91-96 will fit on the crank but you would have to change around your accessories (PS, Air, etc) because the 91-96 cars uses a single belt. The 89 HO uses two belts. I'm not sure how all the 91-96 accessory brackets would bolt up to the HO block and head but I think it would be a lot of work.

    I'm kinda in the same boat. I have a TEC-II and it needs a trigger wheel as well. I've decided that I'm going to weld a 60-2 trigger wheel to my stock crank pulley. Note there are two different types of crank pulleys, I'm using one that doesn't have the rubber isolator in it.

    I'm planning on using something like this:

    Mind needs to be a 60-2 and not a 36-1.

    I hope that helps.

    That works out beautifully, The only accessory I am using is the alternator, nothing else since they came with manual racks. You're the best old86EXP!

    save time and put your ho head on a newer 91-96 1.9L bottom end. that way all teh brackets are sure to fit. the only thing you need to worry about then is the passenger side motor mount.

    If I put the HO head on the newer lower end, would I be able to fit the crankshaft timing belt gear? The timing belts between the two engines were different, Same in size but different teeth pattern. The Pre 91's had a trapezoital shape while the 91-96 were a modified curvilinear pattern. I think it will be best for me to stick with my block and just purchase a megasquirt trigger wheel that is available, just need to be sure its concentric with my crank pulley when I weld it on.

    Not all 91-96 were the cuvilinear. Some, if not all of the 91's had the older belt teeth. If I still had my 91 engine I'd give you the crank pulley as it had the old style teeth.

    This works too and might be a better option. The 91-96 stock pistons were flat (HO's are domed) and combined with the HO head would yield a lower compression ratio ideal for turbo charging. I'm not sure how the block would bolt up to the gearbox but from what I understand most CVH's will bolt up to our old MTX's.

    Sounds like a great project. Please keep us in the loop. Regular updates and lots of pictures. :D

    Well I just purchased my a 1991 harmonic balancer with crank trigger wheel on it and so far the hole diameter and key ways are identical. I am 90 percent sure this will work for my application (1989 Ford Escort GT engine) since I only have one belt running my accessories. I can already emphasize that those of you who are running two belts cannot use the 2nd gen pulleys since they are designed for serpentine belts. The distance the belt rides on from the timing belt seems to be pretty damn close. All I am worried about is timing cover clearance. I may have to trim it since the pulley is about an inch bigger in diameter. However more details on crank trigger swaps will be posted by me when I get the pulley on and find the bracket that holds the sensor in place. This will be a great addition for my Megasquirt processor on its way right now!!

    Thanks for the update. Post some pictures once you get everything setup.

    Ok, I just installed the 91 Harmonic Balancer on my 89 HO and it fits like a charm. Except a few factors that all of you should know. The timing cover will not fit without some trimming. I wonder if the 91 timing cover would work as well??

    Anyway that is one factor I am not to worry since I am going for the tuner look.

    The other factor is the timing marks. Its comparably off a little. All I did was line my pulley up with the new one and by using a string just locate the point to mark on the new pulley by going from center hole diameter passed the old pulley's mark to new one. Where the line touches, you mark. However there are two timing marks so do the same process with the other marking. I used my dremel and made small nicks with an orbital stone. This way I am able to adjust my timing when I get the rebuilt short block.

    The other is the main factor. There is only one belt for the new pulley. For those who plan to use two belts, you wouldnt be able to unless you convert to the serpentine belt setup, will it work I have no clue. However if you choose to run just one belt you can use the alternator and a/c, or one of each. I just have an alternator and it lines up perfectly. The factory belt (NON A/C) using NAPA's number is 25-050355, with the 91-96 trigger pulley you have to use belt 25-050370. 1.5 inches longer since the new pulley is bigger. I have to say it looks really cool. I cant wait to install the crank trigger sensor and my MegaSquirt!!!!

    Below is a picture of new pulley
