I'm seriously contemplating the possibility of an engine change for my 2000, and I've read that the 2200 carries an auto box a lot better. A TC would be nice, but a good SC would be fine. Could anyone tell me whether, first of all, I'd notice much difference between a 2000 and a 2200, and also, what the benefits, and disadvantages of such a change would be. Just looking at my options at the moment.
2000 or 2200
- Thread starter FrazzleTC
- Start date
Taking SC's first. The 2200 engine is a much torquier engine. To give an illustration, the 2000SC doesn't reach full distributor advance - usually the earliest engine speed at which full power is developed - until 5,200rpm. The 2200 gets there at 4,400. So the 2200SC is a particularely big step forward for an auto.
On the TC's, don't fit a standard pistoned 10:1 2000TC - it's much too harsh and, especially on the 2" carbs, too temperamental to live well with an auto. If you find one, or rebuild one, with 9:1 SC pistons and 2200TC HIF6 carbs it is a much nicer engine for an auto. Best of the lot, though, would be a 2200TC.
But the 2200TC also requires the most mods to the rest of the car. Because it has cable throttle carbs, you really need the full throttle arrangement including the bracket at the steering idler where the system changes from rod to cable. But you can probably mug up something suitable without the genuine articles. Also you get the problem of the TC exhaust manifold and mating it to the rest of your current system. I can't immediately think of any reason why a TC shouldn't accept an SC exhaust manifold though....

I reckon it would go on but it would be a bit of piss-fit. The SC manifold is cast alloy with flat mating faces on both the head and manifold. The seal is controlled by a gasket on the elliptical mating face. The TC manifold is sealed with crushable copper gasket rings that sit in a countersunk groove around each exhaust port (the tubular pipe actually slotting into the exhaust port by 1/2" or so). As such, the TC head doesn't have the elliptical mating faces, so whilst the bolt spacing is very likely the same, you will lose considerable gasket area, both over the countersunk groove around the port, and at the outer edges of the manifold mating face where the TC head is radiused, but the SC head has the flat mating faces.

If it were really just a case of a bit of fettling to fit the SC manifold to the TC head, after over 40 years of TC manifolds cracking and needing replacement at vast expence, then surely it would have been done by now, and be a proven conversion available to those who wanted it.
I think this is one for Hermione to answer....
I reckon the SC manifold is always thought of as the inferior manifold and people would want to "upgrade" to a TC maifold, not "downgrade" to an SC one. I can't see the copper ring and grooves issues being a killer, it just depends how much mating surface there is to accept SC type gaskets. Only way to know is to try it and I reckon Hermione is the person most likely to have all the bits ready and available off the car.
Incidently, Frazzle, tis he who runs a 2200TC Auto if my memory serves me right.

It can't be any worse than a stock V8 one, or anything fitting to period Jags for that matter. It's a reasonably smooth shape with no sharp angles, although you'll probably get a fair old amount of pressure towards the back, but on the flipside, cyl 1 exhausting might create a bit of draw on cyl 3 (the next to exhaust)...
Michael
Personally I'd fit a set of rings to the engine you've got, and for this kind of money

for a choice of sizes how can you go wrong?

Hi guys 
,
The cast iron SC manifold will NOT fit the TC head,although the bottom bolt holes line up the tops don't,
I think the easy option would be to find a 2000/2200SC engine as it's pretty much a straight swap although you have to bear in mind that if you use a manual engine the spigot bearing in the end of the crankshaft will have to be changed for the auto one,
Fitting a TC engine to an auto needs a bit more thought,
First there is the exhaust,on the SC the exhaust frontpipe goes right up to the manifold,on the TC the frontpipe stops at the bellhousing and because the auto has a wider transmission tunnel the TC frontpipe won't fit,I had to make a bespoke pipe using a combination of auto and TC frontpipes,

Once you have overcome that problem the next one is the kickdown cable,
Depending on which carbs you use on the TC set-up,if it's HD or HS the solution is to add an extension to the throttle link where the upright adjustable rod attaches to the throttle link, (sorry,no pics of that),
If you use the HIF's a bracket has to be made for the kickdown cable,
These pics show the rod to cable linkage that Chris mentioned,
