May 13b the b2

[heptofite]

I might use the 13b in my current DD since i'm having so much trouble with the 2.9, my questions are as follows:

can somebody make an adaptor plate to hook a 13b to the A4LD? the rotary isn't much on low end torque, but peak is the same as the 2.9, just higher up the band, so if i have an automatic and torque converter it should be okay if i combine it with...


does anybody know where i could find 4.56 gears for the 7.5 and 28?

A 13 B in a Bronco II? I can't help you with the adaptor plate, but I'll help you put it in.

13B+heavy BII+automatic=

A rotary is slow with an automatic when it's in a light Rx-7.

Seriously, you'd be happier and likely cheaper to put in a torquey 302.

Don't get me wrong, I LOVE the rotary.

But it's an engine for a sports car, not a truck.

I know there is one for a T-5 but none for an a4ld, I would still suggest the rotary for a car, but good luck

its an engine for neither

but it is better suited for cars than trucks. pretty much all rx7's came with 4.10 rear end gears with much shorter tires. i don't even think i've ever seen an auto rx7 (the guys at rx7club.com have a pretty good tech library about this) 4.56 is the shortest gears that you'll find with the 7.5/d28 combination but with the taller tires i just don't think that those will be short enough to make it work.

How about putting in a EJ25 series motor from Subaru? The least powerful one make 155hp.
