In reply to # 1961120 by BillC bottom line is although a damn fine engine the dimensions of the Ecotec engine just do not lend itself to fitting in the MGB very well.

Not sure how you come up with that conclusion. The dimensions are close to the OHC B series engines and will indeed fit in nicely. My own measurements indicate that it is so close that you might get away without any bonnet bulge or scoop. Some ancilliaries would need to be moved from the location they use at the front of the engine in the Kappa cars, but some of these wouldn't be used anyway - air conditioning, and power steering pump, and could just be discarded.

Here is a picture of an Ecotec in a Triumph TR-4. No harder than the Zetec, I should think, although I agree that the Ecotec would be about 50 lbs. heavier than that engine.

PS - from another thread:

Quote: Weight on the NA Ecotec is 307 lbs. fully dressed. Engine dimensions are o/a height 25.15", width 25.16", and length 24.64". A Rover V8 is about 27" high (and 26" W and 28" long) so there should be no problem there. I agree that one would need to choose an oil pan and pick up that suited the MG frame, and would certainly have to move some engine accessories about just as one does on the GM V6 swaps.

This is the dimensions of the Duratec , it is about 13" across the oil pan , 17.25 " from crank center line to the top and it just does fit. You have to remove the oil filter and use a remote. Measure the width of a Ecotec oil pan then measure the width between the MGB rails then come back and tell me it will fit okay. The Rover is not 26" at the oil pan , measure the Ecotec were it counts and you will see what I mean. Cutting the frame rails is not option for me, but it will be for whoever wants to put a Ecotec in their B. I'm through with this debate , I already figured the fit and scraped the idea over two years ago if anyone wants to put a Ecotec in a MGB then go for it and good luck to you, I would love to see the how it was done.

No, you're right, the dimensions were overall, in other words, widest, not any specific height above the bottom of the pan, which is indeed wider than a Duratec pan, being almost flat and rectangular.

You would have to actually have the pan in hand to get the final answer on what needs to be done to get it in there. Notching frame members is no big deal. Here's what I had to do to get the V6 in my MGA frame - reduce the depth of the whole suspension crossmember substantially and add a reinforcement to make up for any rigidity lost.

Bill C.

Do you know of a source for plans or a kit to install a Duratec engine in an MGB. I have a '67 GT that will have to have an engine rebuild, so I'm thinking--why not re-power.

Bill And others,

Thanks for your help. I'll keep you posted as to what I do with the power plant. It'll be a-while; at present I'm putting floors in.

It does look like you'd have to shift it from the back seat.

In reply to # 1961120 by BillC ... I am of the opinion that anything over 300hp in an MGB can't be used unless you are building a drag car with big slicks.

Bill C

Have to disagree with you on that one Bill. The MG-Roadmaster certainly exceeds 300 hp and is an absolute joy to drive. Tame as a pussycat putting around town yet plenty tractable enough when you add power. I think 300+ CAN be dangerous and difficult, but it doesn't have to be.

I'm with you, Jim. I've got 3 1/2 years, 10,000 miles on a 300 plus HP MG, and I love it. No big slicks, and zero time on a dragstrip. Here's a pic of it on " The Dragon" doing a pretty good imitation of a sports car.

Here's another one - excellent deal with all the trimmings for $3500, with a larger turbo already!

I don't know the answer to that as I don't know if anyone has tried. OTOH, if they can get a Jaguar engine into a Midget......

We get a lot of questions on this forum that are hard to answer. This is not one of them. The answer is easy - because he wanted to!

And he did a damn good job of it too.

Isn't this engine ran by wire and uses a C.A.N. system? Real bad news if no one has found a way to run it.

No problem, you run the stock GM ECM and use a replacement accelerator pedal.

For the conversion I am about to start. I was seriously thinking about the Ecotec as I though it would be a great engine to use, but went with the LS as the there is enough info on the electronics for me to actually make it run, plus they make such great sounds....he he

Thanks Bill S. for your needed answer. Is there any other photos available, especially of the steering shaft in the TR4. I had a bit of a time with the conversion of a TR3 using a 3400 engine and I won't do that again. I told the guy to get an aftermarket frame for his car but he still drives it without any frame mods. Brrrrrr, gives me the shivers!
