2zz swap? Options

[yaj204]

has anyone done or think about doing a 2zz-ge swap to a 99 celica gt? i was looking at my brothers corolla xrs's motor mounts and both the motor mounts seems to be simular.. i think it can be done but will it pass smog and emission test?

& actually you cant really resleave the 2zz. its a cast iron impregnated aluminum block, you'll ruin it. I work for toyota i know.

The 2zz-ge actually has an aluminum w/metal matrix composite lined cylinder block. The 1zz has the cast iron liner.

the 2zz was designed to

1. provide high speed performance
2. retain low speed flexibility
3. maintain same bore pitch as base engine (to keep same outer dimensions)
4. maintain same emission standard as base engine target TLEV
5. achieve best power to weight ratio in the field.

2zz is a sporty, compact, lightweight, high power, and flexible engine.

what are 1/4 mi times for a swapped 3s vs the 1/4 mi times for a 7th gen?

The aluminum block is hefty and casted really clean. It will allow the engine to produce massive horsepower over stock. Dimensionally they are bigger than the 4AGE, the engine family it is superceding. Block strengthening is possible, by pinning the cylinders to stabilize the bores. The crank is a lightweight design and so are the rods. The crank and rods are casted really well, stress-relief and shot-peen- will produce parts that look forged.

The 2ZZGE has problems. Bent valves from missed shifts have been common. Sticking valve mechanism also cause unscheduled visits to the Toyota Dealers.

Toyota is addressing these problems currently. We have forged pistons in stock and .5mm os available with deeper valve reliefs and a .5 higher compression.

considering i haven't heard of the 2zz being swapped in, i'd really like to see it race a swapped 3s. stock forms of course.
