DOHC B6 Information

[moz]

Going back to nearly the beginning of this discussion.

I've got two b6t engines here with factory oil/air separators.
One is out of a Capri and the other is out of a Mazda 323 gtx

I'll get pictures if of interest

[william]

Yep but it's a bp 1.8 not a b6 dohc like what's in this thread.

so i read on the first page a list of engines to interchange....didn't see a 1993 ford escort gt motor on that list.will this motor not work?thanks in advance

Capri turbo wiring/ecu. Might look into megasquirt or similar, depends how many issues I run into.

[shorestiva]

When I search that casting number it comes back as a b6ze from a mx-3 (eunos 30x to you). We never got that engine in any other vehicle but down there ford had a lot more engine/chassis combinations. I think one or two people have swapped that engine here but it was a long time ago iirc. What wiring/ecu are you trying to run it with?

[reddragon]

Can you see the serial # on the motor itself? Then it's just a matter of looking it up. You could go to a dealer for the info, and maybe take your pics of the motor for the mechanics to look at.

Serial # B6 544469

I'll try calling a Mazda dealership tomorrow

The guy I got it from had purchased it from the wreckers, he was told it was from a 1995 Ford Laser.
VIN number of the car it was pulled from is on the receipt, but a VIN search comes up with 1990 Mazda Unknown

Block has a large BF stamped on intake side. Head is stamped with B551 LI-2

[shorestiva]

Hmmmm that intake manifold looks like what came in the mx-3 here but that wide part at the block looks like a z series block. What did that come out of? You're probably going to have to T off the oil pressure sender on the intake side of the block and run a line around to the turbo.

[reddragon]

I thought I had a B6D, but not everything is bolting up the same. Is this a B6ZE?





Block is wider at bellhousing


Block is wider than G series gearbox.

Where would I find an oil feed on this block, to run to the turbo?

[reddragon]

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....

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.

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.

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.

[reddragon]

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.

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.
