SO found a 91' RT4wd in really good condition but most likely the motor will need to be replaced. I know it will buy it quick so this all needs to be done fast.

What d-series will swap right in the easiest and bolt up to the tranny?

Cant do the swap for my friend myself seeing as i live in apt. so ill have to find someone.

the a6 is a good little engine. i have it in my crx and i love it. it's a d16a6 with a crespo stg1 cam, gutted cat, and a angled fart can. those are the only power mods done to the crx and it's a beefy little motor. i love it.

You can't just put ANY d engine in there, the 4wd wagon uses equal length axles like a B series does. Not all blocks have the 3 bolt holes on the back of the block to accomodate the intermediate shaft. The A6 blocks have them for sure, I have seen y8's and z6's that have them but not all of them do. I have not figured out why. Maybe auto's vs. manuals? Or maybe it's a year of manufacture thing?

Either way if you decide on a different block check the back of it for 3 threaded holes that form a triangle around the oil filter. Sometimes you will find 1 hole only.

SO a d16a6 is a for sure straight swap then correct?

What about a ZC SOHC? was gunna pick one up from hmotors.

As far as I know all A6's will work, as for any other block I can't really say, some will, some wont. Only way to know for sure is to check the block for those bolt holes.

Oh, and before you scrap the original engine make sure you grab the oil pan, as a fwd pan won't work the the 4wd trans. Hmmm.. there's another issue, not all pans fit all engines. If I were you I would go with the A6!

An ODB0 DOHC D16A8 or D16A9 or D16A1 or DOHC ZC should fit by the sounds of it and they all have the intermediate shaft.
