    I'd go for the EXP or '89 Escort engine. Those are the closest to what you've got. Also, if I just remembered correctly the 2.0 block has a different bell housing bolt pattern since it was used with a different transaxle. The 2nd gen engine is not what you want since it was rated at 88 hp. The head is the biggest problem. If that '89 Escort engine is from a vin 9 car, then it's CFI, and basically the same as the 2nd gen, which would make the EXP engine the best choice.

    Specs for that '82 are as follows: 8.8:1 compression ratio, 70 hp @ 4600 and 89 torque @ 3000. Not very strong, but there is plenty of room for improvement. I wouldn't go for the Mexican, either, as that's a different animal, What kind of prices are on those early complete engines?

    Nope, all CVH's have the same bolt pattern. The 91+ Escorts used a Mazda tranny with a Ford bell housing. That tranny won't fit any Mazda motor so it is a Ford bolt pattern.

    Hmm, interesting. So an SPI will bolt to a T5 tranny...good to know.

    Question, I read that when Ford came out with the 2.0L it was just a 1.9L block bored to the 2.0L. The largest pistons I found for the 1.9L were 83.5 mm. Think that would put it at what you said a 1905. Could I use 2.0L pistons and bore the 1.9L block to the 2.0L bore size? I want to stay with the mid to upper 90's block. They look the closest to what I have now.

    Other question is I'm going to try the Chery head, because from what I read the 90's SEFI heads were the worst CVH heads ever produced, not worth a darn as far as flow and valve size goes and I don't want to get into the SPI heads. I want to stay with my original computer and fuel injection system. I did find an 86 hemi head but the distributorless ignition comes into play. Now finding a cam for the 1.6L head has been my problem. Know of anyone that sells a performance cam for the 1.6L

    82mm is the standard bore. 83 is the one that will give 1905 cc if I'm right.

    Volume of a cylinder time!

    Stock displacement per cylinder is 464.1 CC. Total engine displacement is then 1856.4 CC...barely in range for calling it a 1.9.

    87.88mm stroke, and 83mm bore. That equals 475.5cc per cylinder. Total displacement increases to 1901.9 CC. I was close :p

    Jumping to the 83.5 mm bore will yield 487 CC, and total displacement will go up to 1948 CC. Doesn't sound like much, but hey, it works. However, you'd have to jump at least another .5 mm in bore to get to 2.0L displacement, for a total of a 2mm overbore. Personally, I think the walls will be too thin, especially if you're looking to increase power. 1mm...perfectly safe. Beyond that I just wouldn't trust.

    The CFI/SEFI heads are pretty much the same, and use the Lean Burn head (you did read the Cylinder Head Guide Sticky...didn't you?). Those have the smallest valves, but can fit the largest all the same, as well as be ported out to equal a hemi head.

    If you've got Ford based EDIS, you'd have to use the '91 and later cam, which has a tab for that system. The '86 head might have the fuel pump push rod hole in it, which is used by the EDIS in later models. You'd have to convert to roller lifters to make this work. You would also have the lowest lift of cam as stock.

    Keep searching this forum, as there have been orders regarding late model regrinds. If you use the Chery head you have to use the Chery pistons, since they don't look like they'd work well with the CVH heads. If you used the Chery pistons with the CVH head you'd have low compression, which doesn't sound like what you're after.

    Yes I read Sticky's thread on cylinder heads. GREAT info.

    Think I'm just going to stay with the Chery altogether and just do porting and polishing on the Chery head and see what that gets me.

    Going to match intake to head and also header to head. Go to a 50 or 60mm TB, and upgrade the ignition to MSD.

    I would however like to find a 1.6L performance cam. I've seached here and really could find any threads that talked about cams other than the GT and turbo cams.

    I think my problem will be finding a 1.6L cam that supports the distrubutorless cams.

    If your cam is flat-tappet, you can easily have it reground, probably for $100 or less, and you'll have the specs you want. Kent or Piper cams from the UK would work. Measure your cam's journals and verify they're the same as the 1.6 CVH stepped ones. If they are, you're good to go. If not, see if you can have bearings pressed in. Look at www.burtonpower.com for cvh cams...they have an excellent selection.

    Where is your EDIS pickup located? Is it on the head itself, pointed at the cam, or is it a toothed wheel located at the end of the cam, on the pulley?

    It's located on the back of the head.

    Measure your lobe lift vs. a 2nd or 3rd gen cam, 'cause it's likely going to be the same.

    Not to be rude and interupt but,

    He's saying this is a 1.6L EDIS. hmmm, sounds more like the Fiesta\Aspire Engines to me, which swapping a 91-92 1.9L would be a Improvement over that, am I wrong? 93-96 1.9L had the Emissions mess added, and thats more hassle.

    Also, unexplodedcow, I thought you worked mainly with the Distributored 1.6L Engines from the early to mid-80's. If this is a EDIS, then shouldn't JeffScortLX be giving him the pointers? Opps, he does Forced induction engines. I know you put good numbers out with your Escort, but dealing with the 90's EDIS is completely different. Something I'm still yet to figure out. (BTW: The Roush tuned Mexican EDIS Module sounds like a good idea, might have to price that up...)

    ^ Your clueless and in way over you head on this discussion.

    The Fiesta\Aspire is 100% not related to the CVH in any way. The only reason its EDIS is because some Chinese company chose to rip off the design and update it. A CVH is pretty much a CVH weather it has EDIS or not. There were some changes but the basic design remains.

    I know how the EDIS system works EscortDriver ;). Though I specialize in the 1st gens, don't think that I don't know my way around other CVH designs, or the EDIS system itself. It's not just used on Escorts, but practically everything from the mid to late 90's used it, and I've dealt with it. I prefer the distributor since it seems to be more reliable. I've seen far too many dead coil packs....almost every time I go into a parts store someone is changing a set out. Maybe it's the area, or the maintenance they don't do. I think a distro also gives the option of hardware tuning along with software (if the EEC-IV is hacked and remapped of course).

    And no, the Fiesta and Aspire are completely unrelated in engine design. The US ones didn't even use a CVH (although the UK version did use the 1.1 and 1.3). I haven't dealt with those much, but they're not compatible at all.

    I agree that the Chinese ripped off the design. I don't know if the redesigns are better or not, as this is the first time I've even heard of a CVH clone. However, I have dealt with many, many small Chinese-made engines, and pretty much all of them have issues from poor manufacturing or metallurgy. Hell, I'd take a Tecumseh and their wonky carb setup that's prone to clogging over a Chinese Briggs any day. But that's me :p

    It actually makes me a little bit proud knowing that somebody stole our engine design...it must be pretty great!

    Agreed, although I've been saying it's a great engine for years. I did a little more digging on the head design, and the closest thing Ford ever made to the CVH was...no joke, the 427 SOHC. The combustion chambers are just a larger version, even the spark plug placement is the same. The exhaust chambers are D shaped, and they used very slightly oval intake ports. The cam/lifter design was rather different, and it shows how Ford tried to cut corners with the CVH. Still...it's a proven design. Long live the hemi.

    UnexplodedCow has given me some GREAT advice. I do beleive he knows the CVH engine better than most.

    And BTW...THANK YOU for all your help!

    Here is what I found for the specs on the cam:

    Intake - 37.559mm/1.478"
    Exhaust - same - 37.559mm

    Journal
    #1 - 44.74mm/1.761"
    #2 - 44.99mm/1.771"
    #3 - 45.24mm/1.781"
    #4 - 45.49mm/1.790"
    #5 - 45.74mm/1.800"

    If you like I email you the owners manual on the engine. Lots of info in it. You may be able to tell exactly what year they copied. If you want it PM me your email address.

    Speaking of Fiesta I was a little annoyed to find out Ford is going to release a new compact under the Fiesta name. Wouldn't the Escort be a better name brand to revive? Who remember the Fiesta??? (And of the few people who do, how many have good memories).

    The Focus replaced the Escort, what was smaller than the Escort? The Fiesta. Naming it the Escort would cause a conflict in the grand scheme of things. Besides, they have been selling it as the Fiesta in Europe for at least a year now and I hate it when car companies change the name of a car when they bring it to another country.

    This may be a stupid question...BUT is the EDIS just a part that slips onto the cam or is it made into the cam?

    Just trying to figure my options here, if I can buy a performace cam with EDIS or the only option is to have it ground.

    If I have to have it ground I wouldn't even know what to tell the guy what I wanted it ground to?

    I was looking at coil packs and they specificlly say EDIS. And one accel coil pack stated there were two different types in 1999. Anyone know what the difference was?
