DOHC B6 Information

Bf 323 gtx and Kf tx3

Ke tx3 turbo (Kf is bpt)

BF 323

Ford Capri 1989-1994 only about half of them were turbo. In America it was Capri xr2 that had the b6t. However, in australia we got it randomly, there's xr2s here that are non turbo.

What do b6ts come in, in australia

Smaller throttle bodies would give you more desirable response on a turbo car. You don't want a 3 inch throttle body. 40 percent opening could feel the same as 70 percent opening.

I'm not sure about this. The B6D auto throttle body I have is about 10mm bigger than the B3 manual throttle body. Externally they are the same except for a coolant line that goes to the idle air valve but the throttle blade size is different on the ones that I have. I also think that the B3 tps can be modified to work by using pieces of the b6d sensor but I haven't made one up yet.

Dig through my danger zone build thread. I'm running a 6d throttle body with a b3 tps. Just had to make little brackets to hold it in the correct position.

2. The throttle body from the Festiva should be used on the b6d manifold. They are the same size, but the b6d tps is different and they aren't easily swapped. The festy TB is a direct fit.

3. The Festiva distributor must be used. It fits the 16v head, but the locking bolt holes don't line up. There are 2 remedies for this. You can shave a couple thousandths off the retaining cap and use it to lock the disty, or you can make a sheet metal adapter plate that bolts the head and the disty together.

I think a BP distributor would work, as in physically bolt up, but I haven't checked the signals that the distributor is sending out. There could be some internal parts swapping required to get everything working. I don't have a spare BP distributor but I'll keep my eye out for one to try some things with.

Escort GT wires seem to be a lot easier to find.

[bhazard]

Look at an xr2 cap and a festy cap and you'll see why

What is the purpose of using the Escort GT wires instead of the capri wires.

any problem with a 91 automatic capri to my 93 manual festiva , can I use my ECU injectiors ect. its not the turbo
thanks for the info!

That's a great engine to use. The automatic capri was 9:1 compression and can easily be turbocharged down the road if you want more power.
You can use all your festiva engine management equipment, including injectors VAF meter. You will use the Festiva distributor, but you'll need to shave a little off the cam cap that secures the distributor. This is to clamp it tight since the clamp bolt holes won't lign up with the Festiva distributor. You'll run Escort GT plug wires.

I've been asked for a parts list to bolt a Capri b6d into a festiva. Here is my best effort. If anyone wants to add something then let me know and I'll edit the list.

1: 1991-1994 mercury capri B6D engine.
2: good quality clutch (we have had luck with Exedy)
3: modified passenger side engine mount

4: 1 3/8" spacers to space the engine mount from the block.

5: 3 spare transmission bolts to replace the engine mount bracket bolts (longer to account for spacers).
6: various pieces of hose and clamps to reroute the idle valve hose.
7: 10" of 16ga automotive grade wire to lengthen the idle valve wires.
8: new gaskets and seals for the capri engine. (You've got it out, freshen it up a bit).

Thanks.

When you say shave the retaining cap, do you mean the surface that touches thes dizzy, or the surface that tucks under the valve cover?

The surface that contacts the head. This way it works like a clamp to lock the dizzy in place.
