Where to find a 13b engine?
 
I have an 85 automatic 12a motor, that i plan on swaping out for a 13b with a manual. How hard is it to find this motor in the junk yard or are there any websites I can buy the tranny and motor rebuilt or anything. I myself am willing to rebuild but I dont know where to begin looking for these motors. Send links if you ahve any

any 86+ rx7 will have a 13b in it, I have found them to be mor common than 12as i the junkyards for rebuild kits check www.atkinsrotary.com and www.mazdatrix.com

The mounting location for the transmission crossmember is going to be about 5" too far back.

1st gen tranny bolts to 2nd gen 13b and tranny lines up fine

Not on an automatic car with the transmission mounts 5" farther back.

damn the double post

tranny lines up to a first gen as long as you're not driving an SA... no trannies but SA trannies mate up to the holes in the tranny tunnel. that is, unless you don't care about preserving the seals and the stock dash locations, either.

What do you mean by an SA is that the specific type of Tranny? Or the model of the car, and what happens to the seals in the stock dash location?

Also with my 12a, would it be best to find a tranny to fit it and then port the 12a, I dont know if it would give me the power though i mean rather than going 13b. Eventually i want to make it twin turbo so that adds more planning. Basically should i stick with the 12a and port it or go 13b?
