Best swap for a an older Toyota truck

physisist777 · 08-14-2009, 02:08 PM

So I have been scouring the internet for information on engine swaps for a 1987 22r. mine has been giving me issues for a while and finally took a dump last night (literally looked like it shat an oil and coolant mixture all over the engine compartment). given my research I have found the following about a few engine conversions

- The 22r is a very reliable engine if maintained correctly (except mine for some reason) So, many people recommend keeping the 22r if at all possible. from my truck, I find the stock 22r is great for mountain/ light 4x4 use but gutless hauling a trailer or at highway speeds.

- The 3vz is one of the more common conversions. in many cases, the existing transmission can be used but some argue that it may be pron to early failure from the much stronger engine. a fair amount of modifications are needed in terms of mounts, wiring, and fluid lines.

- The 5VZ is becoming very popular due to its high power to weight ration and reliability. there exist quite a few bold on induction power upgrade accessories or this engine. But, depending on the age of the truck, their will be significant modifications. such as, a hood scoop for the larger engine, beefier front suspension (some argue the 5VZ is too heavy for a 22r front end), wiring harness, can use a R151(22re-turbo) transmission but needs a bell housing from an V6, the transfer case spline probably wont match, needs a different oil pan, etc...

So, my question is...first of all, are my conclusions above mostly correct? secondly, what is yotatech's collective opinion of the best engine upgrade in terms of light offroad capabilities, towing, fuel efficiency, highway travel, and overall complexity/cost?

I am also curious about the 3rz 2.7L as well, I just learned of this conversion an hour ago from my local 4x4 shop. but I know nothing about this one other than it is a 4 banger

Does anyone go from a 22r to the 3.0? I would think most would rather go from a 3.0 to a 22r/re/ret. The 22 series is more reliable and almost as powerful as the 3.0. But if you want to tow/haul or hold 75+ on the freeway I would go 4.3 chevy or the 3.4 Toyota.

physisist777 · 08-14-2009, 05:10 PM

That's kinda what I though....I heard (today in fact) that the 3.0 will get you a V6 yes, but has a similar powerband as the 22r. maybe I have just been mistaking the 3vz for the 3rz...which makes sense on hindsight...

the 3.4L would be awesome, but seems like way too much work than its worth...except for the "cool" factor of having an 87' with a 3.4L in it.

yeah, what about Chevy and ford blocks? how do they compare on the above criteria?

Anyone ever done a 2.5L Subaru outback engine? my current car while my truck is down is a 97' outback and it has more balls than my brother's 96' 3vz tacoma.

Tacomas don't have 3vz's.. The 3vz is a 3L 6cyl.
The 3RZ is a 2.7L I4.

Google up "Clampy", it's a build from an offroad mag where the put a 2.7 into an 85..

Seems like your not willing and ready to put in any work for an engine swap.

Rebuild your 22re, thats going to be the easiest way to get back on the road.

Diddo just rebuild your 22R and you will be just fine you will notice a signifigant change in the seat of the pants feel on a rebuilt engine...this will also be the cheapest option but that still doesn't mean its not going to cost you exspecially depending on your mechanical abilities as far as the more work you can do on your own the more $$$ you will save!

Never heard of one. It has more balls because its lighter and designed for a car. Put it in a bigger heavier truck and it wont be fast.

And its a 3RZ not 3VZ
