Just signed up and I'm looking for advice

Sun Jan 21, 2018 5:20 pm

Hello fellow all-trac owners! I've had my 91 corolla DX wagon (4A-FE engine) for about 5 years now. Got it from the original owner with only 95k miles on it. I've made some modifications but I'm looking to get a little more power out of the engine.

I have put a custom performance muffler on and thats about it. What else can I swap out on the car to get a little more power? Please use laymans terms as I'm quite new to car modification!

Install a 4A-GZE or a 20 valve 4A (can be found on eBay), really anything but the FE engine.

Whats wrong with the FE? Its been incredibly reliable so far, I've road tripped all over the US.

Reliable yes but when it's more power you want, it's lacking.

Even just a normal 4AGE should make a difference. F heads are for economy, G are for performance.

Would be more 'plug-and-play' too. . On top of that, (depending on where the OP is located) there is more aftermarket support for an older 4AGE as opposed to a Silver/Blacktop in the states.

Being that replacing my engine is both out of my zone of expertise and out of my budget, are there any suggestions for increased performance on the 4A-FE?

In that case I would say look for a header and drop in (K&N style) filter that'll work for you application. . If you don't see a header for you app, I'm sure one could be fabricated to fit. On my first Celica (a '94 ST w/ a 7Afe) I recall modifying a Corolla header to work.

Thanks! After some research it seems that a cold air intake and header is the right direction to go. I appreciate your input.

A good tune up can help a lot too. Fresh fuel filter, plugs, wires, cap & rotor, O2 sensor and having the injectors cleaned can bring back some of the power lost over the years.

THIS... I purchased a 99' 4Runner recently and did all of the basic maintenance items listed above as well as all of the fluids and the difference in drivability was night and day.
