2200SC engine into 2000TC

I've located a good 2200SC engine, and am considering it as a replacement for my 2000TC engine, which is getting a bit tired.

Apart from a slight loss of originality, it would be a winner all the way really, lower compression, no more twin carb tuning problems and more refined. I'm prepared to bet I'd not notice any loss in power either, given the way the 2000TC runs on unleaded, even the posh 98RON stuff only just works!

So as I see it I need the following
1) Exhaust downpipe. I'm OK with this, as the 4 into 1 on my TC has seen better days anyway.
2) Do something with the throttle linkage
3) Do something with the choke cable. I might be able to use just one of the TC cables, from out of the splitter block thing.

I believe the diff ratio is the same, and I know the brakes are the same, between my late 72 car and a 2200.

Has anyone done this same job, and if so have I missed anything?

Cheers

Rob
 
All the parts you would need to make the conversion work would be on the 2200SC car that the engine came out of, and would directly transfer on to your 2000TC. You'd need the manifold and downpipe as you mention, the throttle linkage and I don't think the choke cable before the split will be long enough to reach the carb, so you'll need an SC one of those too. If you want to retain a working oil pressure guage (which you obviously would) you'll need to transfer the external oil pipe with the sender and fitting from the TC to the SC engine.The only thing you would need to change on the engine itself is the spigot bush if the engine originated in an auto. I can't think of anything else offhand, but it's a very simple conversion really.
 
Harvey thank you so much for the advice.

Unfortunately I do not have access to the donor car, but I'm sure I could find the various bits and bobs from somewhere. Luckily the engine has come out of a manual car though, and I'm assured its a good unit.

I'm a bit worried about devaluing my car, but heck its not like its worth many £1000's is it? Also its present engine basically won't run properly on modern fuels, which is bit of a sales dampener anyway.
 
As for brakes, all the girling cars have exactly the same rear brakes, 2200 front discs are fractionally bigger than 2000 ones, but not so much you'd notice, but if you were worried that the 2200SC was more powerfull than the 2000TC due to it's extra capacity, and that your insurance might think so too (that's not to say they'd be right though) you could always fit V8 calipers, discs and hubs to the front.

I've still got the disks which came off a 2200 I stripped for spares years ago (It was a TC too, but someone had already beaten me to the engine) Good job you pointed the size difference out as I'd never even noticed! The calipers *look* the same, and I've an idea I did swap one of them over at one point, although its a long time ago now.

Incidentally am I right to presume thats its far far more trouble than its worth trying to make a V8 go in?

It can (and has) been done, but IMHO you're better off going out and buying a V8 in the first place.
 
^^^^ RE that thought ^^^^

Rob, had you not considered cannabalising the two engines into one? It's quite a lot of messing (though far easier than a V8 conversion) and you could effectively build the spec you wanted. I remember reading a thread last year where a member had put a 2000TC head on a 2200 block with some decent results. IIRC, the smaller exhaust valves made the engine a lot torquier. You could always fit HIF6s out of a 2200TC for further refinement, economy, torque, etc.

Totally understand if you don't fancy it - just a thought! As you say, a tight SC will probably have the same (if not fractionally better) performance characteristics than a slack TC anyway.

Hi Michael

Yes I have indeed considered that option. I think what I'll do is plonk in the 2200SC for now, then if its a good-un then maybe go down the head swapping route, as I plan to keep all the TC bits I take off the car. If the 2200 proves to be a duffer, well at least the car is mobile while I rebuild the 2000TC engine "at my leisure".

The chap who did this job, did he use his HS8's and if so did the needles need changing at all?

Hmmm interesting. The thing with this one I've got, its a really good, solid car AND its tax exempt. It could take me a while to find a pre 73 V8 which is as good. I'm only interested in a freebie tax one as I have various other drains on my motoring budget!
 
Of course a V8 does fit in a 4 cyl base unit....

But I do support your plan. For later try and get hold of a 2200TC head for the bigger valves than the 2000TC head. Whichever eventualy gets fitted use 2200TC HIF6 carbs as Demetris has done on his 2000TC. The smaller carbs gretly inmprove both engines.

Well the engine is bought, yet another ebay purchase! There's a gearbox with it too, which the seller says is a good one.

So once I've collected it, and got this exhaust downpipe sourced, I'll be all ready to do a spot of hoisting!
 
Hi i ve met the guy you have purchased engine from, very nice guy ask to see his rovers if your going to collect. i could nt stop fondling them lol.
i hope all goes well
marcus :D

Picked up the engine today, as you say he's really decent, genuine bloke. He knew his stuff re P6's too, and the V8's he had were absolute beauties. I'll do a new post in the "members projects" section, when I get started on the transplant.
