Engine swaps for the AE92 Corolla

Those links answered all but the question whats bad about it?

Blof-fan · 09-30-2009, 02:40 PM

The intake manifold is a disaster.

With the SC disengaged the standard engine makes only about 90hp or so...thats about 35hp less than the standard 4A-GE 16V makes with only small differences between them...

The intercooler is only barely up to it's task.

The SC could be a little bigger.

But putting all of it's flaws aside...it still makes a very descent amount of Hp's for it's size. It's propely overengineerd and it's very easy to modify.

So I've got one waiting in my garage waiting for some TLC

TLC? Tables ladders and chairs? lol
i thought the standard 4age 16v put out about 97 hp.

Good: more HP and torque
Bad: more HP and torque

In summary, it rocks.

No downsides to that engine at all. Pretty much as stout as they come.

The only thing I can think of is that you'll have to fill up on premium gas after getting the swap.

the ic's do fine.... the problem is placement.... cut a hole in your engine lid (or hood, I guess) and use a fan (or in a corolla, install a scoop to let air in)

the sc could be bigger, but it's a good size for production....

I love that the gze makes no power with the s/c off.... I don't need to be ripping around on the freeway getting horrible gas mileage.... instead I turn it off & get 40+ mpg.... when it's time to go fast, I turn it on (and my mileage down to around 14) and take off... with a C series behind it, it's a very quick car

Exactly. Fuel economy then when a mad max moment comes hit the supercharger Woosh!

The only downside I can think of is having to fabricate IC lines to move from TMIC to FMIC, unless of course you get the GZE hood and mount the scoop on your hood.

That's when having one of these lying around in your garage comes in handy.

Time, Love and hard, cold Cash

Standard 4A-GE 16V early Bigport puts out about 115 hp to the crank
Standard 4A-GE 16V late Smallport puts out about 125 hp to the crank

I really don't like the IC on top of my hot engine with minimal air on it's surface. I think an IC belongs up front for optimal performance

But than you've got the hassle with the plumbing.
When I'm ready...I'm going for a chargecooler setup like in the Celica GT4. I think that is the best choise for a GZE

A SC14 would be nicer on a GZE...pretty common swap aswell, but it takes some adjustments to get it to fit

I didn't say the SC12 is bad...it's doing fine on the 4A-GZE, like you said...good size for production engine in this class...but still

And I didn't buy the GZE and worry about gas milage...I bought the engine for some more grunt in one of my cars.

And not only when i swith it on, but every time I put my foot down.

If I'm worried about fuel consumption, just go easy on the throttle

Water to air intercoolers are only more efficient with ice than an air to air. Under daily driving conditions the air to air can bring the temps closer to ambient air temp than any water to air could without ice. That being said they still work fine and are a bonus at the track, hence why I'm also runnng one.

A proper W2A setup will cool much better than A2A, even without ice.

As mentioned above, the Celica GT4 top-mount W2A setup is very nice.

j2b4osan · 10-01-2009, 05:08 PM

is there seriously a switch to turn on the SC? I always thought it was electronic clutch that engaged under heavy throttle. If there is a switch, this engine just got alot cooler for me. Was gonna do an EV conversion but it's hard to pass up a SC.

Show me something with documentation to say otherwise I would love to see it, even if its close it will never be way better than air to air under comparable conditions.
