How easy does the larger zuk engines go into the 1.6 kicks?

I've thought about the 4.3 and the 2.8 chevs myself. Cheap parts and go into the 300k more often then not (what I've seen). I've also looked at the buick "quick 6" but doesn't seem as good for parts/availability.

i havent seen alot of 300k 4.3s. mine my dads my gpops and my 2 friends all our 4.3s took craps around 150.  parts for suzuki motors to chevy motors is pretty much same in price. got to think to suzuki motors have less parts, easy to maintain, more space in engine bay and they are a whole lot lighter than the cast iron v6s. when you add that type of weight in the front, your steering will be harder, parts will wear faster also the money it takes to do the v6 swap u can do a full rebuild on a suzuki motor and have goodies on it.

I dont know all the details but we got a V-6 with a certain type auto tranny that bolts up to the Sidekick T-case.. Then harness, computer, etc...

the caddy trans turbo 200

theres a stock gm trans that will bolt to a v6 and mate up to the stock tcase?

I don't  believe so, but you can use the automatic on the back of the 2.5L engine to connect to the stock transfer case.

Which one? Isn't the spline count on the OBDI and OBDII t-cases a little different (I want to say output shaft is fine vs course spline)?
