Are All FS Blocks The Same?

[Alejo_NIN]

Perhaps is a stupid question, and i think i already know the answer...YES

but are they really?


from my 626 engine and the msp engine, block wise, they do look the same.
just want to make sure they are absolutely the same



and the head, what other changes, besides the hole where the ditributor goes, are there?

[njaremka]

they are interchangeable, but i don't think they are ABSOLUTELY the same

[03.5MSP]

I think the actual block and head are same, except for the msp cams. Other than that the older FS engines came with a distributor and the newer ones are distributor less.

[DH Motorsports]

No, the FS heads can be different

We use coils, not a distributor. Some Probes use the Disi.

The blocks should be very similar if not 100% the same. Heads can be very different.

[Alejo_NIN]

i'm leaning towards the heads being completely different and the blocks being exactly the same

[TheMAN]

the pre 98 engines have a weaker block and crank

[Alejo_NIN]

is that a fact?

[JDM Sam]

Yes, TheMan has the encyclopedia of Mazda parts.

[Alejo_NIN]

nice, oh well


start looking for a p5 block then
