1mzfe vs. 3mzfe, which one is a better swap?
I'm planning to drop a V6 into my 1988 Corolla GTS and I'm doing research into which one would be the best candidate.
I've eliminated the 3vzfe because of weight and age.
The 1mzfe would be a great choice for many reasons:
1. I have one in the garage, in my wife's car.
2. Older technology is less expensive.
3. It was available from the factory mated to a 5 speed.
4. Good power and economy.
5. Should fit under the hood (I still have to verify this).
6. I have all of the technical manuals for it already.
7. Standard throttle cable.
8. Can be supercharged (I even have the supercharger).
Some potential problems with it are:
1. They are getting old now and I would be swapping one old motor for another.
2. Possible sludge issues (do the new ones have this too?)
3. Power, while good, could be better.
The 3mzfe has one huge advantage in my opinion.
1. I could get one in a wrecked car that has less than say 50K miles on the odometer.
2. Also, more displacement means more horsepower and torque.
The disadvantage is:
1. I don't really know this engine. Is it basically the same size as the 1mzfe? I think the two are very similar, aren't they? I would need to verify that it would fit under my hood.
2. I've heard that the throttle-by-wire is calibrated for economy and not performance. I don't think I would care as long as it was still fast enough. I would need to know to what degree, this thing is scaled back.
3. Also, I would need to know if there were other things about the engine that I would need. For instance, to use the stock ECU on the 1mzfe (and the OBDII setup), I would need the charcoal canister. Does the 3mzfe have more extra components like that?
So that's a lot to digest, but it really comes down to the basic question of which engine is the right choice. I have a higher level of confidence swapping a 1mzfe from a Solara for instance, but it's hard to resist the calling of a newer engine. If I can't find a 1mzfe with a 5 speed, I would have figure out how mate one up anyway, so what's the difference in doing that with a 3.0 liter or a 3.3 liter (I already know that the E153 transmission will bolt up to both engines).
Let's hear your opinion on this.
Thanks for hanging in there on such a long winded question.
