search the bigger area craigslist. I've seen at least 2 complete 1.6s selling for 100 dollars. May just end up paying shipping.

i found a block for $100... my car is a 93 and i know this is known as the long nose crank...

my question is, are the blocks the same just different crank? Is there a way of telling a short nose from a long nose engine from seeing the block by itself (no crank pulley nor crank)

I've seen a vin stamp on the intake side of my engine before, I know its there. Match that up to this;

Taken from the historic SNC page on m.net - http://www.miata.net/garage/crankshaft.html

Also, I'm 99% sure everything you got for your original 1.6 should work fine with any other 1.6, short nose crank or not. IIRC the only difference between them are specific to the crankshaft and its components. I see the ATI damper pulley for example does not work with the SNC cars. But things such as the rods, pistons, valves, should be the same.

Check the vin and ask FM. I'm sure they could clarify everything for you.

Vash-

The blocks are identical between the short and long nose crank. The only differences are the nose of the crank and the pullys. You should take it all to the machine shop and have them clean and polish it all up, measure everything, and tell you what bearings to use.

Make sure you are extremely careful with the bearing surfaces of the crank. Don't let anything touch or scratch it in any way.



BTW, I never got a PM?

i wish i had time to do this. nice.

Just get yourself some headgasket repair in a bottle and throw it in your oil and you'll have all the time you ever need :bigtu:


Sorry Mouglie...had to be said.

lol... i got some left over if anyone needs some...

HA, atleast you're a good sport about it.

a bought some dremmel tips, a burr(sp?).. looks like a drill bit but has alot of fine lines...
i'll try this tip tonight to bore the intake side of the cylinder head...

Don't give up - or listen to the jerks.
 

You should be able to find a short block for a reasonable amount of money.
try searching on car-parts.com to find parts recyclers near you.

I'm taking a 9 hour round trip drive to pick up some seats and my 1.8. Don't be afraid to go for a drive to get your block.

That said, building a motor starts with the machinist and ends with you.
1) Have the machine shop do the head work. It'll save you some major pain.
2)Buy a quality torque wrench. I'm fond of the clicker style these days.
3)Buy a good engine build manual - or buy two and compare the specs! Sometimes they contain omissions or errors.
4)Read through the build process and picture the whole thing in your head before you try.
5)Take your time building it. Don't build it when you're tired!

Good luck!

I'm not impressed by the jerks on the board who waste posts belittling people. It looks like you'll have a pretty impressive dash if you're any good at finishing fiberglass work!

One other thing: You should probably find yourself a decent 1.6 long block and drop it in there to run while you build the new engine up! That way you'll keep from rushing the new engine and if you screw up your turbo install, you'll only risk an old engine.

Oh yea, i forgot about your mega-transformers dashboard, how's that coming along?

Thanks, i found one a couple weeks back, had to drive 6hrs roundtrip for it...

the machine shop has already bored the block and ported the valve seats for my FM valves... the block should be assembled by saturday. I'm porting and polishing my cylinder head to save me the money, once i finish, the machine shop will install the valves, springs, lifters, all the good stuff. Wednesday i pick up the engine... all i need to do is swap the oil pan for the one that i tapped already, valve cover, alternator... intake manifold, etc...
i'll post a pic to show an example
of what i've done...
good advice Willo, i did think about it but i have 2 more cars... all i do is go to work and home to my garage. Work on the miata for 2 or 3 hrs a day and call it a good day. I plan on running the car first on just engine to make sure everything is working fine... once convinced, the turbo install will begin...
Once again thanks for your post.

here is a pod made for a friend...
