Re: 4age and wet or cold weather

Yup sounds like water/moisture in the spark system. Distributor cap is most common. Also check the spark plug valleys in the engine head. There's the ignitor/coil too. Carefully check the wires for any cracks too.

Re: FX-16 gear ratio/manual trans

You could source a transaxle from a 4AC Corolla, they were geared taller. It kind of takes the fun out of the 4AGE though, the 4AGE isn't a torque monster and it dogs down low. I had to use a 4AC transaxle for a while as I rebuilt my FX16 one and it wasn't as fun.

Re: Timing woes and tps'

to check if distributor is set correctly, I like to remove the cap and look at the rotor and the sensor lobes. WIth all the timing marks set correctly and at TDC, you should be able to visually verify that the rotor is pointing at spark plug 1. Set the crank to firing position, I think 10DBTDC and v...

Re: Timing woes and tps'

Can think of a couple things, maybe distributor is a tooth off? Although I would think the engine would run really crappy. Other possibility is the crank mark is off. It's a know thing to happen that the rubber layer in the pulley cracks and it starts moving. To check that you;ll need to be able to ...

You have to vent or you'll run into problems. What happened to me is you'll have fuel puking out the gascap when the pressure rises high enough, which it will.

Your fuel pump died? Did you change the fuel filter too? 3 year old fuel is pretty certain to be bad and gummy. Change and clean what you can. You might consider sending your injectors to a cleaning and testing service, they'll be able to quantifiably tell you if they are clogged. The services are q...

I suppose anything is possible, but I would think it would be so much work that it would be just as easy and better to use a standalone. I imagine the flow rate and fuel maps for a 20v would not be close to a 2001 Corolla. The rev cut in the 20v is quite high, the 2001 Corolla I would figure to be l...

Yes. They have varying levels of custom shafts. You can have just the center shaft made from high strength steel but retain stock joints and ends, or go full custom from end to end.

Putting a 20v into FX16 is pretty much the same as an AE92, I just finished reinstalling completely rebuilt 20v into mine. Transaxles interchange so you could use existing transaxle, except for one complication the starter. The 20V starter is on the intake side, which really is better, because of cl...

Skies the limit on the engine.
Aftermarket on anything else for AE82 you'll need to get creative. About the only thing you can find is SuperPro poly bushings. Suspension there are a few kits that might fit. Front brakes you can fit on AE92 disc & calipers if you ditch the dust shield.
