Son and new wife are on their honeymoon so I'm doing a few things while he's away.

I've decided to move the position of the crank trigger from it's normal location on the rear of the engine block. Usually it picks up the 36-1 trigger signal for the EDIS from holes or pegs on the rear face of the flywheel, but we will be using a 2.3 Mustang flywheel instead of a Focus flywheel. The pressure plate heights and clutch disc matches better to our bell housing and transmission.

we'll move the ignition pickup to the front of the engine by using a 36-1 trigger wheel on the front balancer. I got the Thunderbird turbocoupe bellhousing cleaned up and have to weld on some material in order to add a couple of mounting holes. We're not using a 4 cyl T5 so I need to turn the input shaft down to .590" to fit the Focus pilot bearing.

I made a mockup of a bracket for the serpentine idler wheel. I have to get a new water pump and finish the alternator bracket in order to check the dimensions. Once I do that, I'll carve the bracket from some aluminum stock. We'll tension the belt at the alternator by turning some rod ends or clevises.

I was going to look for a Contour oil pan and pickup but I think we'll wait until we see how much clearance we have.

That's kind of it for now. When my partner gets back, I'll let him update photos.

just curious why you didnt go with a bp? the 1.8l miata bp and either a 6spd or 5spd that came stock would have been a lot easier and they make just as much power and get the same economy as the zetec

There are any number of off-the-shelf RWD packages that would work well in an MGB. I've seen Toyota, Nissan, Mazda, Duratec, and Zetecs put into these things. The Zetec/T5 is compact, fits well, and weighs almost 200 lbs less than the MGB engine and trans. Personally, I wanted to use a 4.0 Rover V8 that I have at my friend's shop! I think a Duratec would have been a good choice, too.

Just like the Miata, the Zetec has a lot of community and aftermarket support. The Brits routinely use the engine in everything from early MkI and II Escorts, Fiestas, Mondeos, and a host of others. They've done the goundwork for most of these kinds of swaps.

Then when we looked at the stuff we had leftover from other projects just laying around the garage it kind of made sense. We already had a bellhousng and a T5, a Megajolt controller, Mustang radiator, bike carbs, SU's (if we don't like the Keihins), and a lot of other bits. We have access to machines and fabrication tools, so making a bracket, milling a piece of aluminum, or turning a shaft is no big deal.

There's also was the cost. Zetecs are dirt cheap. We paid $250 for our low mileage engine, but have run across them for as little as "free". Not so with the Miata stuff. Good 1.8 engines and 6 speeds are still a little pricey. For the price of just a single 6-spd miata trans, I can buy five T-5's.

As far as easy, this swap is pretty straightforward. The flywheel fits, the trans and bell bolt on. Heck, the only hard part is making a water manifold to run to the radiator from the back of the head. I think there's probably nearly as much fabrication with any combo.

Finally, when you are tire-limited for traction, you can only use so much horsepower anyway. 10 or 12 lbs/hp makes for a pretty lively car. The MG will only weigh about 2000 lbs when we get finished. With 150 RWHP or a bit more, it will be pretty quick.

Anyway, it is what it is, we have it and are committed to making it work well.

On a honeymoon huh? Sounds like you guys have nine months to finish this project before you're stuck with it yourself. [hihi]. Sounds like good progress too.

Hey everybody. I'm back! [8D] We've made a lot of progress on the build and I have a lot of parts photos.

I was able to paint the block a few days before the wedding. I started by cleaning the block as well as possible by using some Marine Clean and some wax & tar remover. Then I just brushed on some gloss black POR-15 top coat. It's extremely glossy and dried hard as a rock. It should hold up much better than rattle can paint. Currently most things on the engine are just mocked up. The head is just sitting on the block with the junkyard valve cover and the windage tray and oil pan are just held on with a few bolts.


If you spotted it from the first picture, I'll be using an oil filter relocation kit from Summit Racing (p/n: TRD-1113). It'll give me plenty of clearance from the chassis rails. My dad was nice enough to get this for me while I was gone.


The windage tray needed modification to make room for the starter so I cut the sides of it off since they were unnecessary for my build. Both sides look about the same.


I cleaned and spray painted the water pump housing with the flat aluminum VHT high temp paint. I still REALLY like how easy that stuff is to paint with. I also ordered a new Motorcraft water pump (p/n: PW368) while I was gone since mine was busted. Dad and I have it installed to the water pump housing but the pulley and the housing are only mocked up and held on by a few bolts for now. I still need to get a new idler pulley and belt tensioner.

You can see the original cylinder head for the engine in the background. I might clean it up and sell it later.


I also ordered some Stage 2 Comp cams. They were purchased on this forum from Earls32 and they're still brand new in the box. They look like they'll work very well for what I'm after. He also sold me new ARP cam bolts and camshaft seals. I just need to buy some adjustable cam gears. I'm hoping to get some Fidanza's.

Here's the other update I promised. If this sounds a little vague or spaced out it's because I'm watching Walking Dead.

I'm planning on using this 1992 Escort (1.9L) flywheel. It's used but in pretty good condition. It had a light surface rust but cleaned up well with a wire brush. The Mustang flywheel bolt holes are 10mm while the Zetec bolts are 11mm. I'll just need to open up the holes to fit some Zetec Flywheel bolts.


We'll be using a release bearing from a 2001 Camaro LS1.


Here's a T-5 from a 1996 Mustang (3.8L V6):


And here it is as we mount it to a bell housing from a 1992 Mustang (2.3L):


Now I need to look at getting a clutch kit, starter, and some hardware for the flywheel and pressure plate.

We're mixing and matching a lot of parts, but it's not just a bolt-together. The input shaft of the transmission has to be turned down from .662" to .590" and shortened by about .380".

We're using the Escort flywheel because its a lot lighter than the Zetec flywheel (about 6 lbs less) and the Mustang clutch will bolt on. We're adding a trigger wheel to the front of the engine for the EDIS crank sensor.

Still have to make bushings for the bellhousing dowels to properly locate the bell and we still have to decide whether to mod the block or mod the bell for the top two bolts.

Despite how awesome the weather has been lately, I haven't taken my MGB out in a few days. That's pretty cool though. I feel like I've only seen a couple other MGB's driving around town.

if you need any cam buckets for setting the lash on those cams let me know. got a bunch of spares
Hey Tim. That'd be great! I'll PM you when we get around to it.

I've definitely gained 30+ hp with the recent mods to my valve cover.



Don't worry, it's a spare from the junkyard.
On a more serious note, I have a ton of parts on the way to help complete my engine build. I can't wait to really get this thing put together! Expect a pretty hefty update sometime on Wednesday.

Funny.....[thumbd] Good help is hard to find.....

While he was messing around with the valve cover, I was tediously measuring tappets with my micrometers.

Couple of findings: I noticed that there are no markings of any sort on these buckets or the ones on the stock head and all the tappets are within .001 - .002" of each other. There isn't any great variation from one to the next and most speced out the same.

Second, after all that measuring, I don't think I want to used the ones that came with the ported head. I'm not a fan of using used lifters or buckets on any engine and there are some circular scratches that came from lobe contact. Looks like either the oil had something in it at one time or the cam wasn't well lubed, so out they go.


Also, we tested the EDIS/Megajolt setup. Worked great on the bench with a trigger wheel on a drill. Lots of big sparks from the coil pack! I've already developed a couple of ignition maps to start with. Go to http://www.autosportlabs.net/Main_Page to see more on Megajolt.

Like he said, lots of parts coming in, so we can finally button this thing up and finish putting the transmission on. Then we can pull the MGB engine, set this one in, and start making mounts.

sweet build! been reading through this from the start. Although I don't know much about these cars, my uncle is a big fan. He has the third floor of my families appliance business warehouse filled with junked/ partial cars like this, not sure if they're the same model though. he has a couple running ones and tons of partials and even a burned one lol.

Good luck cat wait to see this finished!

redSVT_03, that sounds pretty awesome. I bet your uncle has a lot of cool cars to work on and drive. I wish I could have that much space for our projects.

As far as progress on my build, I've been so busy that I haven't updated. All the parts that I ordered were delivered. I took some photos of the stuff before I started tinkering. Here's a shot of the Mac shorty header that I'm going to use. I looks like it'll flow better than the stock manifold.




I'll be using an Exedy OEM clutch kit for a 1992 Mustang 2.3L.


I also bought a cheap, new Bosch starter for a 1992 Mustang 2.3L.


We installed the head using ARP head studs and mocked up the engine using a random alternator and the exhaust manifold. You can also see I've installed my new pulleys and have my timing belt ready to go. [:D] It's nice to see this engine coming together.


Today on lunch break, I sand blasted my bell housing and the windage tray so I'll be painting those at home tonight. I should be able to make a bunch of progress and have more photos soon. [wrenchin]

Awesome build. Im considering a Zetec or Duratec in my MGB. Havent decided what build to go with yet. I'm getting a lot of great info from this. Keep it up and good luck.

Not sure the collector of that exhaust will "flow better." That abrupt change in the collector plate from 4 to 1 creates a significant pressure drop.
