Mods for the 3.0 durring a full rebuild
#266
Alright, I could sit and read all the good and bad that everyone is writting and posting links about the 3VZ-E that came in the 4Runners and Trucks. But have a real answer for you and it's the current project that I'm working on that is taking alot longer due to lack of work and as a result funds.
Here is what needs to be done to give yourself a good basis to get more HP than a stock 5VZ-FE.
1. Get a rebuild kit for a 3VZ-FE engine pistons too, though they usually come with the kits. (92-93 Camry)
2. Get heads w/ignition and valve covers from the above engine. (DOHC) you can pick up used heads in good condition for $75 ea. if you shop around. Rebuild them. Or you can buy rebuilt heads from TAP Recycling for $450 ea.
3. Get the entire intake plenem (3 pieces) and TB from a 3rd gen. 4Runner/Taco. Yhis is needed to bolt to your new heads.
4. Have headers made or fab them yourself if you have the means. Dual 2 1/2" exhaust or single 3".
Then if you want, you can do all of the porting and polishing and all of the other stuff that people are recommending.
I've been hesitant about talking about this, wanting to be the first to finish mine, but if you're in the process and want to know what I'm doing, there it is. This all bolts right up since they are essentially the same block. If you know the engine codes and have worked with Toyotas enough you'd be surprised what all will change over. The Celica owners out there know all about head swaps with Toyotas.
You might ask the reason for the intake from a 5VZ and not the stock intake or one from the 3ZV-FE, and here is the answer. The stock intake....the lower part that bolts to the heads is now too wide for the new larger heads and the upper part will not bolt to the lower of the 3VZ-FE or 5VZ-FE. The 3VZ-FE intake will work, but will face your firewall, which isn't good (have to thing how it was mounted in the Camry). So the 5VZ-FE being a RWD/4WD application will make it face the right direction.
I could make this post insanely long with all of the info that I have about these engines and Toyota engines in general, but I won't. If you have anymore questions feel free to reply to this or message me.

Damn. This is all good stuff. I'm still learning alot about these engines and the persistent bashing of the 3.0 feeds the flame to make it better. Anyone seen a throttle body spacer for this one? Not sure if it would be a great idea or not but perhaps a small improvement.
Also, no one brings into consideration the longevity of these engines. 2nd gen runners are still all over the place. Mine has over 200k on the odometer and is still running strong. Just an aside.

take a razor blade and cut the seal on the air mass sensor, pull open, gently with a knife blade. You will see what looks like a ring in a military compass, there is a arm holding the ring tight. Mark where the arm hits the ring and there back the ring counter clock wise three(3) notchs. This will allow the mass air sensor to open quicker and allow more air to enter the truck, you will notice a difference

i can't believe this thread died... so sad... i bet it would have been a good franken-motor. i put rebuilt heads, crower cams, and headers on my 3.0 and the only time i really feel an increase in power is when i use nitrous lol. (yes for real... let the NOS bashing begin...)

Im new to forum But not to toyota's. i work at a dealer in NY and picked up a 95 v6 runner with a bad rod knock that eventually put a hole in block the size of a grapefruit. Besides the hole it also broke starter into about 10 pieces as well as taking out oil pan and its baffle. I decided to forgo gettting another used engine seeing as none i could find were under 100K and went with the toyota parts catalog . NEW toyota short block and heads as well as anything and mostly everything else that was needed to put engine back together from scratch. i will have pictures up soon as engine is sitting on the stand as my prep department is cleaning up engine bay to complete my showroom looking engine bay.
got a ??? just ask me......
