2000 bored to 2200

I'm pretty sure I came accross one bored out to about 2250cc, so going to the standard 2200 bore size, which IIRC is a 0.188" overbore in the 2000 block, won't be a problem.
 
It's on my to-do list. I even have a set of NOS pistons ready - bought from Iran of all places.

Trouble is, my to-do list is rather long. :(
 
Steve in US from this forum runs such an engine in his TC. I am sure he will come along to comment.

Also i remember that quite a few 4 cyl owners in Canada went this way. If i remember correctly if you use the 2000 rods you will have to make the little ends a little narrower in order to fit the 2200 pistons.

I was also considering this. I have a spare block and new standard 2200 pistons, but my 2000 engine is in rude health even after 110K miles, so i was not convinced that this is a priority. Even less now that my TC is not my everyday transport anymore.
 
I may do it considering my engines out :) I wonder if any of them have been on a rolling road?

I would like to see the figures

Interesting info about the little ends Demetris. I'll keep a note of that.

Well, your machine shop would eventualy bump into this!
Effectively you will use the 2200 head gasket, but if you retain the 2000 head there is slight mismatch of the coolant ports to take care too.
There is much more detailed info in the forum. Try a search on the subject.
 
Here I am Demetris!

I've bored my car out from 2000 to 2200. In my case I wanted to lower the compression a little to cope with the awful modern fuels we get here in the US. I still have the 2000 head on there and ran it with the HS8's. She runs fairly well but I felt fueling was a little off with the standard needles. (AAB iirc). If I had her running very rich at idle she would pull like a train at running speeds. Unfortunately there wasn't a lot of options above that range in the standard needles for the HS8's. I did fit HIF6's this year and that helped a lot, certainly with lower end pull. Performance was up a little on the 2000 even with the HS8's, quite a bit when running rich. If you are in the UK and have access to a rolling road with a knowledgeable SU tuner I would see if you can get the HS8's reneedled. It definitely had a lot of pull when running rich.

I used standard 2200TC 9:1 cr pistons along with some used 2200TC conrods instead of modifying the original conrods. I had no real issues with the coolant passages on the 2000TC head and head gasket, but I was using the original 2000 block so maybe that was it.


Best,

Steven
 
Unless your engine needs a rebore, I doubt its worth it. Rover did a lot more work on the engine when they went to the 2200 P6 than just putting in new bigger bores and pistons. That wouldn't give you anything like the improvment Rover got when they introduced the 2200. Would seem to me to make better sence to take out the 2000 and put in a full 2200 unit.
 
The only changes I'm aware of for the 2200TC were:
Bored out to increase capacity, stroke stayed the same creating an over square engine
Larger valves on the head
HIF6 carbs replacing HS8's (HS8's had replaced HD8's around 1966-ish)
A re-curve of the ignition timing if I recall correctly.

Otherwise the two engines were identical.

But I'd be happy to be corrected.
 
The head had better cooling too. So saying " apart from that the engine was identical " is a bit like saying a Rolls Royce and a bicycle are the identicle because they both have wheels.
 
So five changes? Not that huge a difference between them.

Head
Pistons/conrods/bore
Carbs

Let's try playing nicer huh? To be honest you sound a little unpleasant in your reply.

Edit because I'm a little pissed off now.
The block (apart from bore) is the same
Crankshaft - same
Timing chains, sprockets, tensioners - same
Camshaft - same
Crankshaft - same
Oil pump - same
Sump - -same
Water pump - -same
Exhaust manifold and inlet manifold - -same
Fuel pump - same
So, yes, mostly identical

Right. Putting aside the irrelevant posts, i want to continue the discussion on the subject.

As far as i know the whole story of the boring out to 2200 started in Canada, where oversize pistons for the 2 litre engine were not easily available, in contrast with standard 2200 pistons. So for them it did make sense to do the modification. Also, for anyone that has a 2000 engine that needs a rebore, already has a set of new 2200 standard pistons, and doesn't really want to splash out over £200 for a set of oversize 2000 pistons. Finding a complete 2200 engine (that doesn't need a rebore too...) is something very different.

Anyway, you said about the better cooling of the 2200 head. Could you expand this a little? How did they achieve this? Other improvements over the 2 litre unit that we are not aware of?
 
I believe the water ways were changed , thats why there is a bit of a mismatch in the water way holes of the 2000 and 2200 heads.

Of course it would give improvement your increasing the bore size :LOL:

Anyway that aside My car is an 1968 2000 sc I have a 2000tc head and cam and even the dizzy I will also be fitting 2200tc carbs.

The later flat top /2200 Pistons give a smoother feel to the engine and will increase torque and bhp, I wanted to keep the original block so its numbers matching hence why I wanted to see if anyone has actually bored out a 2000 block with out any problems.
 
It certainly can be done and will give some improvement, I didnt say it wouldn't. To get all of the improvement you would need the 2200 head with the bigger valves and better waterways. But that wont fit on a 2000 block.

Once the 2000 block is bored the 2200 head will fit.
 
I've always thought that with the bigger valves the head would not fit, but boreing out will alow the head to fit a 2000 block then. Well live and learn ! lol
 
Yep, can confirm. I've seen one engine over here that's had a 2200 head fitted to bored out block. The waterways seem to be fine between the head and block.
@Herts2000, yep it can be done. You see some improvement, mostly feels like extra torque. And, yes, the HIF6 carbs are the way to go for fuelling. Especially as you won't have the higher summer heat there we have in NY/NJ.
