Having trouble understanding the gze motor specs

[bmw5002]

Ok so uve got the:
1st gen? AE92 Japan 88-90, AW11, with AFM, 145 hp
2nd gen? AE92 Japan 90-91 with MAP, 165 hp
3rd gen? AE101 Japan 92-95, Levin/Trueno with MAP, dual-exhaust, 170 hp?

Am i right here?

Now for a bunch of questions:
Now i have a 91 corolla with a 4a-fe.
1. Which of these will fit with the existing mounts?
2. Do they all have the same mounting points?
3. So the only fit dilemma i have to worry about is fitting the intercooler under the hood right?
4. Which generation is most easily obtained?
5. Basically im going for the most power, without any mods. My rolla needs more pep and a gze motor seems like it would be the best. Which would you recommend for my car? Or would you recommend something else like the ge 20v or something?

Thanks in advance for clarifying.

Don't focus on the HP numbers so much. The AE92/AE101 MAP versions are fairly easy to obtain.

This should answer the first questions:

the "165" version was afm using a larger crank pulley for the sc
the "175" version is essentially the same motor using a MAP setup

Hm, according to this source, the 165 hp version was MAP, as well as the 175 version.

It was produced to the request of many critics sighting the MR2 to be underpowered at the time of mid-80’s power wars of the 1600cc class production engines. One year after the MR2 Supercharged introduction, the engine was used also in the AE92 Levin/Trueno siblings as a front drive power plant. Both of these first edition 4A-GZE produced 145ps JIS at torque curve of 21kg/cm, running at 8.0:1 compression rate. Indeed, it was the most powerful engine in the Japanese 1600 class.

A first major revision of the 4A-GZE was done in the 1990 model year solely for the front drive setup as MR2 gave way to the newer and larger 3S-GTE power plant. This second generation of 4A-GZE utilized the now commonly available Japanese market pump gasoline of 102 octane. Accordingly, the compression and boost was raised to produce the 165ps JIS figure. The compression was upped to 8.9:1. The newer engine also utilized the new 4A-GE block and bottom components based on the 90 and later Levin engines, comprising of stronger larger crank and rod journals as well as piston pin and used semi-forged coated pistons. The new 4A-GZE also featured the only DLI (distributor-less ignition) used on the 4A series and the AFM was replaced by the MAP system (latter probably due, more to cost of production, as MAP systems are much cheaper to manufacture)

In the succeeding years the engine was carried over to the AE101 Levin/Trueno Line up, and now used dual-exhaust and slightly more efficient charge cooling to produce the 170ps JIS to make the most powerful 4A-GE engine ever to be produced for normal consumption. This was the final version as the 4A-GZE gave way to less powerful but more sophisticated 20 valve 4A-GE, for it’s normally aspirated pleasure and the lack of popularity for the supercharger engines in the Japan’s market (thanks to Honda’s VTEC…ughhhh!)

yeah, well you gotta take a lot of that with a grain of salt....

basically the 160-165hp versions were the ones that came with a larger crank pulley from stock (to bump it up to 10psi) and used 8.9:1 pistons..... ae92's came with this motor (after the 145hp version... 7psi 8.0:1), but there were AFM versions.... i know this because we bought 8 of them as a group buy... those 2 were bigport 4agzes.... also, the latermodel map version was a smallport motor

So anyways....

1. Any 4A/7A series will bolt in.
2. Yes, same mounting points. There have been some issues with the rear mount, but I didnt have any issues.
3. Your hood will latch I'm still driving around with my hood in a latched state. I removed the rubber insulation and airflow is pretty good.
4. Just avoid the early gens (AFM) and go for the latest version, AE101/MAP/DLI. Of course, an AE92/MAP/DLI would work just as well.
5. I wouldn't trade my GZE for two 20V's. Personally, I'd rather make gobs of torque down low than no torque at high revs.

What's wrong with the AFM model? Just cause it makes 145hp?? If anything, this would be the cheapest one to install, and the easiest model to find parts for, as it came in the AW11 MR2's, any Toyota dealer would be able to get you parts for this motor without breaking your bank.

The AFM models are teh w3ak!

Yeah. I'm only putting down 180 whp and 160 ft lb of torque on it. I wonder what I would have gotten starting off with the other motors.
