I'm thinking the 3rz is 150 hp and the 5rz is 190hp.
That's correct, the older 3RZ's are 155 HP / 177 Tq (1995-2004) and the newer VVTi version is 163 HP / 183 Tq (2005+)
I have raced a Turbo 22R-TE, a 3.0 V6, and a 3.4 V6 up the same steep grade on HWY168 up to Shaver Lake, and I can pull all over the Turbo and the 3.0, and slowly distance myself from the 3.4. Seriously. When you think about it, the 3.4 only has 25% more horsepower than the 2.7, and that's apparently not enough to cover the extra weight of the newer trucks (as my truck only weighs about 3300 lbs).
As for the 3RZ swap, I could go on for days talking about this topic.
But I want to scare you first. It will cost you roughly $1500 to complete the swap, if not more. Figure about $800 - $1200 for an engine complete with all wiring harnesses and ecu, and an extra $300 - $500 or so for the misc things you will need during the conversion.
As for wiring, the 22R-E would be much easier since you won't have to do any wiring. Your chassis and body are already setup for the 22R-E harness, so you can just basically keep the looming intact and just install it into your truck (as I see you have a 2nd gen truck). The hardest thing would be working on the interior and ignition. You would have to remove your dash and place the new looming into place. I am talking about having a complete 100% harness with all sensors and everything, including the ignition..
As for the 3RZ, I have complete notes for the 1st gen and 3rd generations of the 3RZ (1995-1997 & 2001(?)-2004), I just need to get them up online for everyone to enjoy..
But even with the wiring notes, it will be a lot of wiring and soldering and heat shrinking to do the job correctly. I will not pretend to tell people that this is a cake job. Even for me, sure it's cake because I've done it a couple of times, but its still gonna take me a couple of days to get it finished.
But let me tell you, the rewards from the 3RZ are OUT STANDING. Sometimes when I've raced a moderately modified 22R-E setup, I feel like "If I loose this race, it's going to be REALLY embarrassing considering all of the work that Ive done" but then I just realize, how could someone build a NA 22R-E engine that could out perform a 22R-TE engine? NO WAY! At least nothing that would be a daily driver, it would be some special machine for sure, and then I remember, well geeze! my 3RZ IS BONE STOCK!!!!! What if I put the same amount of work into my engine! Holy Crap- So It is soooo amazing to have a completely stock engine, thats completely stock Toyota reliable, makes over 20 mpg on the highway, and has more power than both the Turbo 22R and the 3.0 V6, and it is all so Light weight, works with a lightweight drivetrain, has NO clutter under the hood, and is smog legal (here in Cali).
If I had to do this again, I would never even think about anything else than the 3RZ. Not in a million years.
In fact, this last weekend we just took Bevin's truck out for a test drive for the first time, and this is the 2nd fastest 3RZ truck Ive driven. His truck is really fast!! And he is so happy with the 3RZ that he has already bought a 1963 Toyota Stout, and we are looking for yet another 3RZ to swap into the Stout and convert it to a 4WD. Pretty cool stuff man
