Terrible news
so im not sure this is the right section but i think it will do.
i have a 1990 miata ive been modifing for about a year. i put all fm suspension hawk break pads a 96 dash and a few other goodies.....i love the car but it seemed to be getting slower and slower latly???
So today im leaving work and its just dead slooooowww....i mean foot to the floor in first gear not going anywhere...so i check the timing and its wayyyyyy retarded.
i took apart the timing and front cover and found what i suspected. the crank key and broken and the crank gear is flopping around on the crank..:( :( :(
as i planned to be turboing this car in less than 2 months now its time to make a chioce.here are the options i see
1.swap in a 1.8L and call it a day and turbo that one
2. swap in a used 1.6 and turbo that (lnc this time)
3. sorce a crank and rebuild the motor i have
4. swap in a mazda speed 1.8 turbo...(this possable?)
what would you all do?
what would you all do with a bud

the mazda speed motors are all over ebay for around $2k so if that swaps in easy that would be a decent deal i thought since by the time i buy a 1.8 swap that in and then add a turbo im looking at closer to $3500ish....

I know they are not identicle but to my knowledge the differences are minute.
I could have sworn the only real differences were the cam and the fact that it is plumbed for turbo lines already. I own one so I would like you to open my eyes if there is something I am missing that actually means anything.

Didn't say they were stronger, I said they were different. BP4W pistons are 9.0:1 CR and MSM are 9.5:1.
Generally speaking, you don't get more power out of an MSM motor compared to the BP4W (you're limited by the rods either way), so it usually does not make sense to pay a premium that is usually demanded for the MSM motor.
