4cyl dohc only came in the 94 95. do you need the sohc 93 or the dohc 94?

I need the 93 sohc im guessing then

just to make sure, does the valve cover look like this?

if it doesn't you definitely need the sohc

(sorry to hi-jack the thread)
SuperK, you keep taunting me with that pic! i'm trying not to buy that intake, but you're not helping!

and if needed, i can take a pic of a SOHC. although i just sold my '92 and they are very much different. OP, can you take a pic and post it? i might be able to find you one at the local JYs for like $75 or so, although i'm in FL.

Do you still need a head. The yard has a 93 by me. Let me know what you are looking to spend and I will check out the yards prices. ( I wouldent think it would be over 30

)

Yeah i need the sohc my head is not that beefy! >jealous< but i just need one because mine has a bad cylinder psi on one so idk shoot me some prices! i live near det

so im guessing it would be cheaper to just buy a used head an put it on right?! but how hard is it to swap to a dohc?

Hey man, just call all of the scrap yards around you and ask for a BP. I swear you'll be happier. Don't bother repairing the SOHC head, just spend $300 and drop the whole motor.

ask for 1.8L DOHC motors that came in:

early proteges, escort GT's, merc tracers and kia sephias....

do some wikipedia research: Mazda B engine

It plugs right in, no worries at all.

if you have low psi on a cylinder, that's usually not an indicator to replace your head.

Having a machine shop RR your head is cheaper than anything. If you have your head resurfaced and stem seals replaced you're looking prolly about 200 dollars max.
If you get a used head, you're going to want to do exactly this anyways, so use your current head.

Your low PSI might be your actual piston rings wearing.

Ok so my two best options are to have the original head machined or upgrade to the 1.8 dohc but with that dont i have to get trans and new mounts and stuff?

Ryan · Post by **Ryan** » October 13th, 2009, 9:37 am

Nope. Same trans bolts up, mounts bolt up. You only need the ECM (not even right away) and abot 3' of any kind of wire. Maybe some electrical tape.

I LIKE THE WAY YOU GUYS THINK! what is the difference in horsepower for the two motors because i think mines get what about 87 horse?

Ryan · Post by **Ryan** » October 13th, 2009, 10:40 am

B6 SOHC - 88hp
BP DOHC - 130hp (same as K8)

I got to drive a BP-T a couple weeks ago. Definitely a fun engine.

I would, though, encourage, if you purchase an engine from a junkyard or elsewhere, might as well rebuild her before you drop her in.

So save up some money before you decide on what you'd like to do. Do the job right the first time, so you don't have to try again a second.
