MGB Zetec? Yes please.

Hey guys. I'm not so sure if this thread will gain much interest but I'd like to share some progress on my most recent project. I've recently become an owner of a 1979 MGB and I'm in the process of swapping the original 1.8 Liter engine with a Zetec engine. I've joined the forum to learn more about the Zetec and seek out parts for my build. So far, I've really enjoyed reading what you guys have on the forum.



The MGB is a great, little roadster with responsive handling but it suffers from an underpowered engine.

I think I'm making about 55whp with the stock engine. The Zetec is a reliable and economical engine that has a pretty big following in the US and the UK. I'm planning on using bike carbs and pairing the engine with a t-5 transmission that's already in my garage.

I'm currently finishing up my work on the suspension and brakes. As soon as I'm done with that I'll be working on building a Zetec and fitting it! Please stay tuned and I promise to update.

Subscribed! I'm a fan of MGB's and I think the swap idea is awesome. You definitely came to the right place for info and parts on the Zetec.. Good luck with the build!!

Here's a video of a Zetec with bike carbs [driving]
This probably very similar to what I'm going to do. I already have a Megajolt Jr. Lite from a few years back to use as an ignition controller.

I got my zx9r carbs in the mail today at work. Talk about a distraction! I predict that these will produce more hp than a stock Zetec. [thumb] I'll have to fabricate my own intake manifold at a friend's machine shop. They came with black trumpets but I think I'll use something different later on. The bottom picture shows the correct stance for the carbs.

I'll follow up with more parts photos and plans for my build.

Happy Thanksgiving, everybody! [cheers] I'm thankful for finding an active forum with knowledgeable members that have plenty of positive input![ffrocks]

I've been pretty busy working on the front suspension of the MGB but haven't uploaded any new photos of my work. I'll update everybody on that soon. In the meantime, I figure I'd post some pictures of some Zetec parts.

While this isn't performance related, I thought this would be a nice finishing touch for this engine swap. When I first joined Focus Fanatics, I purchased a metal Contour valve cover from 2GreenAutos. He also included a Massive Speed Systems hardware kit and Oil Cap. I wanted the valve cover to look relatively modest so I ground down the Zetec and Ford logos and had it powder coated with a wrinkle black finish. I also purchased a polished, stainless steel spark plug cover because I thought it would look pretty slick. Here are some photos of the finished product.

Hey guys,

I hope all is well with everybody. I've suddenly come down with a cold but figured I could give a small photo update. I've been working on the front suspension a lot. Within the last week or so I've been able to replace all the old, original rubber bushings with polyurethane bushings from Energy Suspension. This involved replacing bushings in the lower and upper control arms and the front sway bar. I decided to go with black bushings because they contain graphite and are more resistant to squeaking.

While I had the front suspension apart, I cleaned up and painted the components to keep it rust free (and looking good). This car was well greased and garaged by the previous owner so it's pretty much free of rust. One thing that bothers me about the later MGB's is that they have a very high ride height. I was able to cut the coil springs and lower the car to match the rear ride height (The rear currently has saggy springs and it conveniently lowered itself with time).

Here's the before photo:[thumbd]


Here's after cutting the springs: [thumb]


With the new bushings and the lowered front end, the MGB handles a lot better. I believe the car currently weighs around 2500 pounds (about on par with a NB miata). With a Zetec engine, T-5 Transmission, and a chrome bumper conversion I predict the MGB will be around 200 pounds lighter. [headbang] I'll probably have to cut the coils again to make up for the weight difference but it's really easy to take this car apart.

In other news:
I received a really nice gift from my parents and swapped my old, ugly steering wheel with a classy Moto-lita steering wheel. They also got a nice wooden shift knob to match. It's a VERY nice gift and I got it just in time for the Daytona Turkey Run. I know it's a little off topic for the Zetec swap, but I'm pretty sure my dad lurks this thread so I'd like to give a big THANK YOU for a very nice gift. Also, note the painted gauge rings in the after photo!




What's next for the MGB:

Before I get too involved with building up a Zetec, I need to finish replacing components on the rear suspension. This will probably include new leaf springs, lowering kit, rear shock conversion, new polyurethane bushings, and axle straps.

I'll be hitting a dyno soon to show just how much horsepower this MGB motor really has. I'm also going to have it weighed. I feel like this will show a great before and after difference for the swap. [driving]

This may come as a shock to those subscribed to this thread but I don't actually have a Zetec engine yet. [facepalm] I've been searching for a good engine with low miles. So far, I found a 2003 Focus Zetec with about 60,000 miles on it that's somewhat close to where I work. I plan on showing a detailed tear down and build for this engine.

I've purchased a fully ported cylinder head from ah1f39 and it should arrive Monday. I'll have to update again after I receive it. It should be great for opening up power for a naturally aspirated Zetec. I want to pair it with Crower Stage 2 cams. If anybody has these on their engine, I'd love to read some personal feedback on them.

As always, thank you for the support and the feedback. I'm really looking forward to this swap!

Wow big difference on the before and after shots. Really like that new wheel and the painted surrounds. 60k mi for a Zetec is nothing if it's been taken care off. The crower stg 2's aren't bad at all though I don't have any experience with them besides having a Crower stg 1 exhaust cam on my zetec but, with the head your getting will really wake that motor up. The MG should really fly with that combination. [burnout] [driving]
