I pulled apart the 1.6 shortnose I had and checked to see if they really do have the B6T rods that they are rumored to have. Result: they are just normal rods. This isn't definitive since it's just one shortnose, but it's certain that not all shortnose have the B6T rods. For reference this is out of a '90 miata with a build date of 3/90.

 

um yeah no one said any miatas got the good gtx rods ever i duno how you infered that.

 

as far as i know, the 87-88 gtx is the only b6t that got those rods , here atleast, now go look in nz and every b6t has them rods, and you can snag them super cheap....

 

I have heard it mentioned a few times actually. I did not put much credence to it, but its nice to have someone put it to rest for sure.

 

There have been a couple threads on here https://www.miataturbo.net/showthrea...&highlight=b6t post #3

I was curious if it was true or not, and I had a shortnose motor that was no good anymore so I figured I'd get a hard answer instead of rumors.

 

They only came in cars with a 3.3 R&P

 

Now to only find that elusive car.

 

Just for the hell of it, here is a picture of B6T rods out of a mercury capri, notice anything funny?


All b6's have these rods if they were produced after 1989.

 

I'm opening my engine in 2 weeks, a 1990 (April 1989) we will see :-P
