Thought I'd add a snippet from my build thread

I looked at a bunch of options before deciding on the V6 conversion.
4AGZE - About the same cost of the 1MZ for less HP and less torque.
4AGTE - Laggy, more engine bay heat, needs good intercooling. Too much hassle
3SGTE - Too heavy, too laggy in stock form, fairly expensive. I also don't like the idea of turbo AW11's, something about a glowing red object generating crazy heat in the engine bay puts me off.
SR16VE - Too much custom work, transaxles, shafts etc etc. Bit of a pipe dream idea.

The 1MZ was a good option for me, it is only marginally heavier then a 4AGZE, provides plenty of torque and hp with brilliant reliability.

---

In the assessment of my AW11, the car lacks torque mainly (It's a 4A, can't expect much before 4500rpm). I can drive the ass off it and keep up (and sometimes leave behind) the turbo cars on a good twisty road, but it would be a lot easier to do with more torque and some extra HP. The 1MZ is the easiest way IMHO to get more torque, double the horsepower and provide it all in a reliable, easy to use package.

Ah, my mistake then. Carry on chap

- Complexity in the sense you have a lot more areas for stuff to go wrong. Working on turbos and fixing them are in the majority, more expensive then a natro.

Yeah, no

The peakiness and lag maks it exciting, getting that kick in the pants from an accelleration rush is fun. Weather or not its practical is another matter. The stock Turbo is in no way laggy, hell a 2860 on an MR2 would make poo pooloads better power than your V6 and still have zip lag.. if your experiencing lag with a 3sgte on a decently selected turbo, you're in the wrong gear.

weight, if its really 100kg's then it may be a valid point. Even then, doing the usual bolt on's will save you some weight CAT/DP and changing the Alt bracket should get you around 30kg's

More to go wrong, no, not really. The added 'complexity' of a turbine is most definately worthwhile. Not sure how many people here have had to fix things specifically related to the turbo itself.

Most of your points are just fallacies.

Its pretty obvious that no one will agree in this issue. The same debate has been on every mr2 forum since they first did the v6 conversion.

My 2c

AW11 - 1mz = win. Cmon they're tiny and have a 3.0 v6, thats awesome.
SW20 - 2gr = win. Stock vs stock the 2gr puts out plenty more torque and power than even the latest revision 3sgte.

The biggest problem with this debate is that peoples preferences will always be different. Personally I like the feel of a v6 hence why im ditching my 3sgte for a 2gr. That and i want something a little different.

Yeah even a boosted 1mz would be nice in a sw20 i think but both require a fair bit of mods. That is if you want them to be reliable.

wtf? The 1MZ isn't low revving - it makes power all the way to the limiter and doesn't feel "out of breath".

---

I think by low revving he means the rev limit is set fairly low. I think its like 6500 or something.

It's set "low" because Toyota normally don't want their engines to end up as a pile of little bits of metal....
