If you look at horsepower as your basis for a good engine then the 22re is not that good. It does have a very good torque curve for a truck though. I will agree that 8 valve's has its limitations and I think it would be even better if it where 16V. But the durability and design of these engines for trucks is awsome. The only reason that they use a 2.7 now is that they need a cross platform 4 cylinder engine for all their vehicals. The 2.7 is a front wheel drive designed car engine. Intake and exhaust on the same side. I bet it is a good engine but I like the engineering of the 22re.
So I'm curious - even seen a dyno run of the 3RZ to know how it compares to a dyno of the 22R-series? Usually a little displacement is good for bottom end torque.
I've read nothing that says the 3RZ is unreliable or unsuited for truck use.
I think the largest advantage that it has - same reason I turbo'd a 22RE - you can bolt it up to the stock driveline w/o spending a fortune to adapt it.... The next motor I do will very likely be the 3RZ.. A turbo version of course, but it certainly peaks my interest. Consider it part of the evolution of solid toyota motors!

Look on Pirate4x4 for 4rnrRick's posts.
LOADS of tech info.
22RE was 112hp / 130lb-ft
3RZ is around 150hp / 170lb-ft
A 22RE -3RZ swap is doable but not the cheapest route.
People doing this will tend to
-- use the marlin bell housing
-- upgrade to an R tranny
-- upgrade xfer to 23 spline
Once you are there the other major issues are
-- motor mounts
-- wiring harness
AFAIK
--AC integration is a case of custom hoses ?
-- PS integration is a case of hoses?
My understanding is that MPG will improve (but I cant confirm this)

Hard to beat a design that came out of 1970, eh?
2.7 does have a power advantage and is a significantly more efficient design... As stated above, I believe it will bolt up with a bellhousing change.
I've seen one aftermarket turbo report on it. The dyno was over 300hp.. Not sure if that was pump gas.
I like the 22R series also, but there are limits to 8 valve heads...

Actually, the 22RE was the second best motor they made. almost all toyota 4 cyl. motors are amazing. the first original bullet proof motor they made that was the best was the 22R. Simple, Easy, And could put out the power of the effort was made. did i forget to mention you don't have to deal with fuel rails and a fuel system?!?!? EAAAASSSYYYYY
