4 cyl swap questions plz help

[zoomzoom]

ok so i have a 94 mazda mx3 with a blown motor. its a 1.6L dohc and i was told it was a b6 but to me it looks like a bp..besides the point i was wonderin if i can get some info for a 4cyl swap. what engine is easiest to install besides the original. jus lookin for somethin with a lil more horsepower at an affordable price. also could i plz get help with any mods i may need doin the swap. how bout a 1.8L or 2.0L? and i also need to know engine codes for ordering. thanks for any help

The engine in your car is a b6. If youre looking for a swap youre best bet would be something like a bp out of a protege. DOHC 128 hp or something like that. Youll need alot though, Tranny, axles, ecu, harness?, time, money. It aint gonna be easy. You might has well get a bpt while youre at it.

Yeah, you'll need the harness unless you want to do a lot of splicing. If that kinda swap isn't your cup of tea then replace some of the stuff from your engine with stuff from the B6-ZE (91-93 miata i believe). I've heard the cams will work fine, but maybe the head and all other guts will too.

so if i went to the bp and change the axles, ecu, wiring harness and tranny..what more would i need to do for a bpt? and isnt a bpt 6cyl? i found a place here in ontario to get a bp with all the extras for like 750, or i can get the bpt for around 1500. other then like a clutch and intercooler what would i need aside from guages and stuff?

[Savin]

I"m not quite sure on the matter. I have not done the swap myself. All i can say is use the search function. and the BPT is a 4 cylinder that happens to be turboed. you might be getting the BPT confused with the KL-ZE. That's an entirely different topic (talking 4 cyl to 6 cyl swap).

why dont you just turbo the motor you already have?

ok so if i went with either the bpt or the bp, would u know if the engine mounts are the same? or what bout a b6t swap? wouldnt that be the easiest? are there any other engines besides the ones ive mentioned that would be an easy enough swap? and for the last reply my engines blown thats why im doin a swap.

[Savin]

Nope, the BP or BPT are your best options when it comes to simplicity...as for mounts, ask someone who knows, lol

the b6t isn't any harder from what i have heard plus with the b6t you can keep all of your stock mounts / flywheel / coolant hosing / radiator you should still upgrade the trans although you don't have to. also search the swap cause someone posted a how to on putting a first gen bp into the new mx-3s cause it is a litle harder

[zoomzoom]

hey ive looked through the forums and i couldnt find the one u mentioned. theres a guy whos done a b6de to a 2nd generation bp but not for the first. either way it sounds like im gonna have to change the ecu and harness for sure, but what i need to know is what bout axles, tranny and engine mounts for the bp? are they the same as the b6?

[projectmx]

i believe you can keep the tans / flywheel / clutch / axles but the trans won't last long with a bp

[zoomzoom]

ok thanks. im still tryin to figure out what engine for sure i have in my car. i called 2 mazda dealers and neither one can tell me even givin the v.i.n. all i know its a 1.6L dohc. i was told it was a b6, but ive looked at pics and they kinda look diff. maybe im already runnin the bp? where bout would i look for the stamp on the engine?

[projectmx]

what looks diff? post pics of the engine and what version of the bp are you saying it looks like?

[zoomzoom]

hey the b6 i seen pics of has more of a rounded valve cover then mine. also doesn't the b6 sit in the miatas different? ill try and get pics of mine soon. i looked for the stamp on my engine and the only one i found was right under the head and above the exhaust manifold. it was somethin like b5517 i think it was, i know b5 for sure tho, so possibly someone did a swap before i owened the car with a b5 with a dohc head?? no idea im confused haha

[projectmx]

this is my old mx-3 with the stock b6 engine and yes the miatas mount differently but it is basicaly the same engine. and the number you posted sounds like a b6 number


here is my bp... which looks more like your engine?
