B6 swap questions

[db2u]

I apologize if this is common knowledge, but I can't seem to make sense of this .I ask because I live in an apartment and have 0 shop space..

I have an 88 carby.

I know the B6 is a direct swap. problem is almost every b6 I have seen is a FI engine. I know the 323 is a good source of B6 engines, but I dont recall seeing any carb models. The Mercury tracer had some carbed B6 engines right?

Since I don't have any shop space, I would like to just unhook, replace and hook up the engine without swapping intakes, changing my fuel system to FI, adding ecu's etc. Is this possible on a carb model? Am I relegated to using just the block and swapping the rest over?

swap all the carb intake and exhaust mani's to the b6 to go carb

I'm pretty sure that the head design changed so you're going to want a b6 that looks just like a Festiva b3. not trying to confuse you but if you ever want to convert to feel injection you want the computer out of the later model version of the basics coupled with the earlier engine b6

[db2u]

Well, I guess that's kind of the basis of my question... I want to do as little work as possible, moving to FI is out of the question... maybe for a future festiva lol...
Just was wondering if there was any way to swap an engine without swapping manifolds etc for a carb donor to carb driver.

Yes you want the 1 that has the intake that looks pretty much exactly the same but it says 1.6 injection on top. However I am Not sure if all of the b6 camshafts have the bump for your fuel pump other members should be able to verify this

Ok cool, just realized that this is not even in the right subfourm. I guess I could wire up an electric pump if I am not too concerned about starting a fire in an accident

The motor you want is from a 1986-89 323, i.e. a gen1 B6 motor. I'm assuming you're in the USA. Might want to put your location in so we can see it.

correct, it MUST be a 1st Gen B6 (mercury tracer 1.6 is a garauntee 1st gen). you must swap your carby intake over, you can keep the B6 exhaust manifold but that requires a new downpipe, though you'll want a 2" exhaust for a B6 swap so it becomes a moot point again. the B6 cam comes with a fuel pump lobe (make sure its a smooth surface, some can be rough). use the B3 fuel pump.

ok so yes u can do the b6 tracer or whatever car but u will absolutely have to swap at least intakes bc they never were carbed.i mean its not hard takes 10 min. and the b6 cam does have the fuel pump lobe but I used electric pump for mine.

If your swapping engines for 80 hp, why would you want to put a carb on it that's jetted for a 60 hp engine. The whole point in the weber 32/36 swap is for the extra hp it is designed for isn't it? It's like putting a 4 barrel carb off a 350 on a lawn mower engine what's the point?

If you are not in california there is no reason to use a b6 unless you have one already. You may have to pay a few hundred bucks for a manifold welded up for you but you can carb any b series engine for a lot less than even chevy 350 people pay out when they discover all 350s are not the same despite what every white dude over 40 says.

Last statement in the most positive light. Im an old ford lover and used to laugh when my cars came together faster and family members had to wait for more parts

Sorry to resurrect an old thread, but had a simple question I'm pretty sure I've read before.

B6 Head + B3 block = B6, right?

Found a B6 head locally for $45.. seems cheap enough to clean it, build it, slap it on. Should also note it's a GEN 1 head/1987 323.

Actually, another question. Can you use B3 lifters in a B6? I have an EFI engine I'd like to take those hydraulic lifters out of.

The B6 head needs to go on a B6 block. Given the larger bore of the B6, I doubt that oil and coolant holes would line up using a B3 block/B6 head. Plus you would have a discrepancy between the B6 combustion chamber diameter and the B3 bore.

Just checked Rock Auto, and the part #s for the Festy and gen1 323 head gaskets are different. The reason for using a gen1 B6 motor is to have the intake and exhaust bolt patterns the same as a Festy's, which lets you use the Festy carb intake manifold. Use the 323 exhaust manifold tho, it's better. Gen2 323s had different bolt patterns for intake & exhaust.

As to the lifters, I don't know for sure but I tend to doubt that you could use the Festy ones on the B6, simply due to the larger distance I believe the Festy lifter would have to travel to the B6 valve. But it's just a guess.

Poop. Thanks for the reply, though, Tom.

technically, it wouldnt be like a 4 barrel carb on a lawn mower, itd be like a lawn mower carb on an even bigger lawn mower.
