MG Engine Swaps Forum

I have clipped this from another website but for those of you who want factory info.

Take what you need from it. I know there are alot of things listed here that some have not believed me on, so hopefully this puts to rest gear ratios and so on.

Engine mass looks a bit high even weighed with transmissions as I assume they did.

I guess it depends on what ancillaries they weigh with.

The first part of your clip made me laugh - "Composite Body Panels Dent resistant and rust proof to keep this vehicle looking showroom new for many years (body wise)"

The weight of the engine is with all accesories. Removed the accesories plus the FI and you have a light weight package.

Engine mass is with power steering, AC compressor, Camaro (heavy) flywheel (and I believe clutch), electric air pump, exhasut manifolds and for some reason, I had the impression that GM weighs the driveline with the y pipe back to the caddy converter and more. I doubt they weighed it with the transmission but maybe?? If so, I bet that they weighed them and transposed the weights. There is no way the auto is lighter then the manual.

-BMC.

If they weighed w/o transmission, the manual may be weighed with a flywheel and pressure plate, while the aito with only the flex plate

The only issue I have with the weight is that the flywheel, clutch and all that cannot make up for 40.8 Lbs. The Camaro flywheel is not light compared to others but hmm... I guess I will have to take some weights and measurements to compare.

-BMC.

No, I wouldn't think so Brian.

Particularly as we are not talking about a 'normal' engine like the MGB where the flywheel is much heavier. On the V6 much of the weight that would otherwise be in the flywheel is on the crank itself so the flywheel is lighter than is the case with most engines (that's why going crazy lightening these flywheels gets you much less joy than in most cases)

Interesting firing order.
One of the few to fire sequentualy.

Pete.

Peter,

The Ford 2.8L 60 degree V6 has the same firing order... But Different!!

GM goes from the front cylinder on the (USA) passengers side front, then to the opposite side which is the next cylinder back, then back to the passengers side, and it keeps going back and forth to the rear.

Ford has Cyl.#1 on the (USA) Drivers side. Then they label the next two behind it- 2 and 3. Then they go down the other bank labelled 4-5-6.

Now even though Ford has Cyl. No. #1 on the opposite side, if they had labelled their motor running down one side, then the other like GM, they would have had the same 1-2-3-4-5-6 firing order. When I work on the MGA or Sunbeam Alpine Ford 2.8L V6 conversions, I remember the GM way of installing wires. FAR Easier!

-BMC.

Brian, I was down at a favourite foreign car shop and they had tasked an apprentice with replacing a set of plug wires on a Lamborghini V-12.

After they go through yelling at him, he was in no uncertainty that the first step in such a task is NOT to remove the caps and wires and put them on the bench. He apparently got through the actual wire replacement OK, but when he went back to the car with caps (they had twin 6 cylinder distributors, one for each bank) in hand, he just stood there scratching his head wondering what wire went where....:-)

I recall a few Jaguar guys that didn't know that they numbered from the firewall as well.

Brian, also keep in mind that the 2.8 Ford does not have a timing chaing, thus making the camshaft turn the opposite of the crank. So the they change everything accordingly. The distributor also turns different than most engines.

I never thought about fiing orders from the firewall! -just dont remove the cap and wires first.

Forgot about that Bill. The Ford 2.8L was good in its day but even then was a bit backwards compared to the market.

-BMC.

On the V6 flywheel issue of weight, the easy way around it is to go to the flywheel and bell housing from a 1993-4 S-10 with a 2.2 motor. Easy to find, because the 2.2 wasn't much of an engine. This also gives you a vertical bolt pattern for the T-5, and you can use the clutch throw out and cylinder from the S-10 as it clears the tunnel in the MGB. Only possible down side is that the with the lightened flywheel the starter on the S-10 is on the opposite side. I made a gig and used a transfer punch to drill and tap the opposite side of the 3.4 block, in my garage with no special equipment. The smaller, lighter flywheel shows no sign of clutch slip on a full burn. Highly recommended, just to get away from having to use a hydraulic throw out bearing. Mine in use for two years absolutely no problems.

Flywheel, clutch, pressure plate, throwout bearing...bet it's close.
