sohc to dohc

[Kenfu]

will a 1.8 dohc head fit on a 1.8 sohc engine (1992 protege)

 

[ROB-80E]

No. Not if it's a BP series.

Yes, the 1.8 DOHC (BP) head will interchange with the 1.8 SOHC (B8) in terms of bolting up. The blocks are identical.

if you search cardomain for bizob, he has a kitted first gen, which is gorgeous, he did that

It might be easier to just buy a complete engine,

problem is the SOHC is lower compression than the DOHC. If you do put the DOHC head on I would reccomend swapping the pistons out for some Miata ones or something.

i have done the swap and it is easier to doa whole engine rather than the head

when u do the motor u will need a trans and mounting bracket
and a few extras

your right, swapping motors is probably easier than a head swap b/c you would also need to piston swap or face an uber low CR.
Whole motor in and out vs. head pistons and all the other stuff you *should* replace while you have the bottom end apart.

The swap seems simple enough I'm picking up a 70k mile BP for 231 bucks, 60 to ship it That's what I would do, SOHC is so yesterday
