4A-GE was used in California cars such as MR2, Corolla GT-S and Prism GSi.

But they are all older than your car, so not CA-legal.

Best bet is swap in 7A-FE for a lot more torque. Chops off 2-3s from 0-60 times. Will be faster than ALL 4A-GE cars except for final-generation 20V models. Even then, only about 0.5s slower to 60mph. Fastest engne-swap for effort (time+money) is 4A-GZE, but again, not legal.

Turbo kits are extremely uncertain. While they can be tuned to pass sniffer with proper dyno tuning with standalone aftermarket EFI system (not much chance with piggyback/FMU jerry-rigging), they will most likely fail you on visual inspection:

- if FPR has been replaced with non-factory item, you will fail
- if you have CA model, removing pre-cat header to install turbo-header will cause fail

Yeah, as mentioned, many smog-test shops were busted for lax interpretation of smog-regulations. Manatory $10k fine and possible jail time. Not very likely you can find shop that'll look the other way when there's huge monster turbo sittin where there should be catalytic. Rules have also been tightened with load-dyno testing for all pre-OBD2 cars. No longer just idle emissions sitting in one spot. They actually load-test cars on dyno at 40 and 60% throttle now. That will certainly generate some boost (positive pressure) in intake manifold and your fuel & ignition mapping have to be spot-on. Test system also reports all results directly to State, so smog-operator has no chance to fudge results.

It's all a racket to extort more money and taxes from populace. State makes money from selling testing-stations to smog-shops. State gets a cut of "smog certificate" fee paid. State makes tonnes of money for "certification EO#" of aftermarket parts in order to sell in CA.

Case in point, I needed new pre-cat converter for my wife's DX couple years ago. There's 49-state version available for $149. EXACT same part with CA EO# stamped on it goes for $479!!! Exact part from same manufacturer!!! And they've got price-fixing lock-down with vendors saying they cannot sell 49-state parts to CA residents. "Will not ship to CA" or some such rubbish!

It's legalized extortion I tell you!!!

Dang so doing a swap is out of the question then.

I think I already have a 7AFE. I'm not sure how to check. My car is a 1993 Corolla DX it's the manual transmission (5 speed)

Look bonnet for emissions decal. Take photo and post it here. We'll decipher what you've got.

It may also be stamped on the block too.

The work around would be to have a friend order out of state, then ship to California.

That's why I left the republic. Price fixing on everything. From food to gas and everything in between.

Recycling fees are the worst. Legal racketeering.

Ok I think it is the 7AFE

So the 7AFE is better than the 4AFE?

I'm not sure if it's just my car or what but sometimes when I'm in 5th gear I accelerate to try to pass another car but I notice it doesn't accelerate that good?

Is that normal or what can I do or what maintenance can I do for accelartion?

The 7A-FE is 1.8L and the 4A-FE is 1.6L. Same bore size but longer stroke in the 7A-FE. This gives it better low RPM torque.

It might be somewhat normal to not have a lot of acceleration in 5th gear. Usually I'd think you should downshift into 4th to accelerate and pass.

As far as a tune-up, you could check/replace the spark plugs, wires, distributor cap and rotor. Check the ignition timing like it specifies on the emission sticker you posted. Check/adjust the valve clearances, which is a bit involved. Put a new air filter in if it's dirty to get a little more air in.

Ok thanks for all your help.

Also, a 7A-FE will have a larger two-piece oil pan, while the 4A-FE will be a one-piece stamped-steel affair.

Yes, you've got better 7A-FE already. Make sure it's in tip-top condition.

Of course using 5th-gear for accelerating is going to be slowest way possible due to torque reduction through gearing giving lowest linear-thrust at contact patch. Downshifting to lower gears will result in more torque at wheels and more thrust for faster acceleration. If I'm in 60-mph range, I'll download to 3rd-gear for acceleration. If 70-mph, downshift to 4th.

My 4A with its non-overdrive transmission was pretty responsive at 70 and above. It wasn't fast or anything, but it could hang (and overtake) quite well, in traffic at those speeds.
