3VZFE vs 5VZFE... Debate!!! - Page 2

conor · 08-08-2007, 11:42 AM

^^^ haha, see.. 5VZs are great if you're going balls-out

- 3VZ/1MZ for a straightforward, simple, inexpensive swap. They bolt up the easiest because they were designed for a FWD car. Everything clears/fits with minimal fuss.
- 5VZ for big-power builds. Doesn't fit as well because it was designed for use in a F-R pickup truck.

Dont get me wrong...a ems and cams will get the 5vz to rev as high as the 3vz and put out more power...some other quick mods will get you more power then all the v6's n/a ....

what about the 2GR-FE

That's a nice lump, but it's a newer generation really than what we're discussing here isn't it? :P

Weasy2k · 08-09-2007, 10:53 AM

the gr is too much at the moment to really compare it all.

monsters5vz · 08-10-2007, 11:10 PM

I vote for 5vz all the way, 3vz has head problems that was fixed in the 5vz and for those that think the 5vz cant rev up to 8000 rpm you just need to regrind the cam profie, springs retainers rods pistons etc, There are guys in arizona racing them in the desert making over 600hp.

You got any links to these guys? Would be interested to see there setups and learn more.

I agree on the power and rev'ability but the 3vz-FE did not have the nasty head problems that the 3vz-E did...and the 3vz-E only had head problems because of cam/header design....stupid stupid toyota...

off topic but i'm curious and have to ask... weasy2k, under your screen name i see "3.4L 10K RPM In the works". You serious?! Have you started undertaking this project? If so, that's

Spektrewing386 · 08-11-2007, 10:41 PM

thats been there for like a year

Weasy2k · 08-12-2007, 03:08 AM

A year in planning...this winter it will come into effect. Gotta put money into my DD Tacoma first...1uz-fe swap into that bad boy.

Toysrme · 08-12-2007, 07:39 PM

if you have the money for raising it's rpm the 5vz-fe.
if not the 3vz-fe. turbo + stock everything 3vz-fe + $80 chinese 12:1fmu = 350bhp
swap to 400cc+ injectors and easily 400bhp+ still no management.

cheap, dirty & not highly optimized but it works.

Dance_Business · 08-13-2007, 02:12 AM

Who has 400 hp and no EMS?
My 5VZ runs great. I had some minor issues that most of you could have diagnosed and fixed in a day or so; I just did not have the skills. I'm learning as I go. I have more pieces to the puzzle waiting and the more I read this thread the more I want to finish mine. I look forward to posting here when I get it done. I do not think, as naive as I am, that there are many V6 swaps that really run out there. I see 70 names at the bottom here, but how many of them drive to work in theirs? Who else autocrosses in a V6?
Someone let me know. I vote 5VZ, again. Not putting anyone's efforts down; I just want to know what happens after the car is built, not what it could do from the engine stand.

Gimpster · 08-13-2007, 02:57 PM

I'm not turbo (right now), so maybe my post doesn't count, but I drive my 1MZ swap into work everyday. Reliable as if it rolled off the Toyota line. I'm not much of an autoX'er and I don't have the money to open track like I used to.

I would love to see an accurate count of running/driving V6 MR2's world-wide too, it has to be < 100-200?, but who knows.

This winter I plan on turbocharging the car, but I also need to finish up my V8 BMW project too. The MR2 runs so darn good and is so fun as it is NA, I might just leave it that way.

I did put a new toy in the trunk though!! Just waiting on some smaller pills to show up. Will be running a 75 shot on it initially.

Weasy2k · 08-13-2007, 03:50 PM

Awesome! Work! We should get the admins here to make a V6 registry :P
