In reply to # 3161056 by BMC Any carb engine that needs a valve job needs an engine rebuild. An XPAG engine that needs to be rebuilt will be costly. If your going that far, look into the roller cam. If you just rebuild the head, your gong to have a oil burner more often than not and it will do nothing for power.

-BMC.

When my 1600 MGA lost power over a period of a couple weeks, a compression test showed two bad cylinders. I replaced the head, because the valve seats had receded due to unleaded gas. The new head did everything for the power loss. Plus, it had showed signs of oil leakage through worn valve guides. If the compression test indicates a valve problem, I'll definitely do a valve job. If the cylinder walls look good, I'll stop with that. If I had to remove the engine for a rebuild, a different engine would be going back in.

In reply to # 3161110 by Ralph 7h Jim,

the Volvo B20 and the 4-speed Volvo M40 gearbox from a P1800 E or a 142/144/145 from 1972 to 1974 can be used without cutting anything. The gearbox has a shifter extension that puts the stick in the right position. The 142... of this years had a cable operated clutch that can be adopted to the original TD-F pedal box. With MGB rear axle and brakes, you can use 15" TR 2-4 wheels or wires. Instruments trom a P1800 E can be used.
The Pictures below show Volvo B20 engines in a TF.

Thanks for that, Ralph. The Volvo swap looks like the easiest, and the engine layout is about the same. I think I'll Google that for more information on the horsepower and possibly sourcing an engine. I'd like to go with a 5-speed, but I wouldn't be surprised if there's a kit for that. Swaps, in general, are easier today with a lot of engineered kits readily available. Back in the sixties, you usually had to roll your own, and the bell housing was usually the biggest problem.

I have to confess to sometimes being tempted to buy a Miata... or maybe a turbo Pontiac Solstice or Saturn Sky, which aren't terribly expensive... yet.

How tall are you? MGB has much more room.

Jim, There are a couple of performance sites for the Volvo and some "How to" on T5 conversions and B18 builds. TurboBricks forum too.

Why not use the B20?

Quote: Externally, this MG TD looks like every other TD series car build from 1950 to 1953, which isn't a bad thing. The only thing out of the ordinary cosmetically is the use of non-wire wheels

Who wrote that article?! No TD ever came from the factory with wire wheels.

I built another '52 TD from spares and a basket case I had. Put in a '37 Ford V8-60 with an '85 Ford bell housing, a home made adaptor plate, '87 Mustang t-5 transmission, and mgb 3.9 gears in the original rear end. It's been fun to build and nice to drive. I had to alter the mounts for motor and t-5, but no cutting of body tub was necessary. Marvin,ct

Carl, I should have said B18 & B20. Actually I would prefer the B20 because of larger bore and newer and easier to find. I like the little flathead 60 V8 also. There was a company that was importing new old stock 60 V8's from France(industrial/military). They can be hopped up to over 100 HP.

Carl,

Jim's car is a TF, so wires had been an option directly from the MG Car Co at Abingdon (not a dealers option as sometimes on ourTD's) , On my TD I would never agree to wires but on a TF they lppk quite well. I think.

Yes, TF came either way. TDonly had steelies from the factory. I have a 55 TF 1500 with wires that has been a looooong time project. It may get a B20 as the stock 1500 is long gone.

I'm pretty average in height. All my MGs are a little tight getting in and out of, but once I'm in them, they fit fairly well. The B 20 swap looks pretty sensible, and I see that you can get 200+ HP out of them, depending on how carried away you want to get. That might be the best way to go, but I think I'm going to be waiting awhile before I jump into this. I'm still working on doing the 18GB swap in my 'A.
