B8 to BP Swap Notes

[FineWine]

After my second B8 to BP swap, I figured this might be useful to someone. I'll update it as I remember things I came across, or as I come across other things.

Keep in mind that my engine and its accompanying accessories came from a Tracer, so they might be slightly different. I also did not swap the axles or tranny (yet).

• Rear radiator hose (block to heater core) is different. The B8's outlet is on the disty side of the engine and wraps around the back. The BP's outlet is in the back, next to the oil filter
• The fuel lines to from and to the fuel rail are different. The B8's are both on the disty side of the engine. The BP's filter to rail line is on the Disty side, the rail outlet (after the pressure regulator) is on the belt side and wraps around the back. NOTE: I had to buy ~2 feet of fuel injector line to complete this connection.
• The Escort/Tracer main harness gromet is larger than the protege (and probably 323) harness gromet. this means you'll either have to swap the harnesses or rig the tracer/escort harness if you don't get the "mazda" one.
• There seems to be more/different vacuum lines required for the BP, as well as more vacuum line connections on the intake manifold.
• The A/C Compressor line connectors are slightly different for the tracer/escort.
• The power steering pump might be slightly different for the tracer/escort. I haven't played around with it enough to see if it will work with my old DX stuff yet, since I think I'm just going AC and PS delete.
• I had to reuse my B8 radiator connectors, but I think this is only because the tracer/escort radiator is different from mine. Can someone confirm?

lets see...

the fuel line issues you have are due to an escort vs. mazda difference. with a mazda bp fuel rail it would plug and play.

the escort radiators are indeed different.

the extra vacuum lines (should only be 1 extra) are for cruise control.

the block hose to the heater core are different because of the oil cooler piping.

Pretty good list you've made, sound about all the issues I found as well.

The extra vaccuum line is actually for VICS since the B8 had cruise control as well.

I thought I remembered having to buy fuel injector hoses when I did my GTX swap a while back...but I might have just been replacing the old stock lines.

Coolant temperature sender is different in "ford" engines. You'll need to swap in your old B8 sensor, or buy a new one, otherwise your temperature guage will not work.

Question: what's the vacuum line on the TOP of the manifold for. Cruise Control?

Which 1? There's 2. 1 is more on the pass side pointing towards the pass fender, that 1 is for cruise. There's another pointing towards the firwall close to the tb, that on goes to a sensor of some sort and I believe that hose goes to the carcoal canister(I think that's what it is called). If you want AJ swing by and take a look at my engine bay. We can have a couple beers or something while checking it out
