DOHC B6 Information

[moz]

Which BP dizzy?
Aren't they electronic? As in no vacuum advance?
I'm curious as I'd love practice javelin with vacuum advance dizzys

[Advancedynamix]

Yeah, they are electronic, but so is the F.I. Festiva distributor here in the states. Is yours F.I. or carby?

[Skrapbob]

What is better option when installing a B6D in place of a B3? Use existing festiva distributor or find a BP distributor?

[Advancedynamix]

That's a good question. As far as I know, using a BP distributor with the b3 system has only been confirmed to run the engine, but hasn't been thoroughly tested. The ignition requirements for the b6d capri engine are so close to that of a b3 that it's a great fit (tuning wise) but the BP distributor bolts up, but may not be timed correctly. Since only 1 car is using this (to my knowledge) and that car isn't dialed in yet, it's too early to tell.

Only real input I have is that I was running a b6t with a bp disty on megasquirt. Couldn't get it to play nice with the b3 one. I should have a b6d running on b3 management with a bp
disty in a week or two.

I'm working on it. haha I'm thinking that it will require some filing of the adjustment slots to get enough base timing. I honestly think the first 3 pins on the BP distributor and the festiva distributor are the exact same magnetic pick up in the distributor.

Has your head been decked? That will retard the cam timing and retard the ignition timing as well.

I have no idea. I bought the motor from the junk yard to have the car running this summer to start getting a feel for the suspension and driving it. I have other plans for a long term power train (that's part of the reason I have a G series and a N/A b6). They said it had about 115K on it and I never pulled the head but I got the impression that someone had at least had the manifolds off before. Since I'm not planning on using it for to long I just slapped new gaskets on it and painted the block.

I think the problem is that the bolt pattern is mirrored over the engine center line. As in the bolts on the outside of the head are both higher than the ones on the inside of the head. Or at least this makes the most sense to me. Ultimately the fitment of the BP distributor may vary engine to engine depending on exactly were the holes are.

[Advancedynamix]

That makes sense, since it was intended for the exhaust cam on a BP, the clocking is probably different.

All ours are carby.

The only festivas that were fi here are the aspires.

[shorestiva]

B3 on the left BP on the right. Both are sitting as if they were installed centered on the bolt holes.


The bolt holes on the sensors are not the same and the sensors are slightly different sizes so you can't swap the b3 sensor into the bp housing.

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.

How much boost could you run on a 9:1 compression B6D? Or would you need to lower compression first?

I'm doing a B6T swap at the moment, but I also have a later model/lower km B6D sourced from an automatic Ford Laser. Have been thinking about bolting the B6T turbo bits onto the B6D. With the higher compression, any idea what sort of power increase it would it be compared to the B6T, and how much would it effect reliability/longevity? (B6T is from 1991, approx 240,000km, B6D is from 1996, approx 110,000km)

Have been searching for info on this, seems like the search function doesn't play nicely with these three letter engine codes.

The Capri guys like using the auto Capri motors because they are generally much less beat than xr2 motors. The compression bump is fine as long as you run premium gas.

I don't see any reason you couldn't roll around with 20psi if you were tuned on an aftermarket computer with water meth injection and had a better turbo manifold and a slightly better than factory turbo.

Sounds good, you have talked me into it.

If all goes pair shaped, will still have the other motor anyway. Plenty of cheap donor vehicles around too....
