GJM85

I spent a lot of time reading through the threads available for the AE92 4A-FC 1587cc twin cam 16 valve first phase motor. I've owned mine for 5 years and driven it from 205000 to 360000kms. I've spent many hours keeping it on the road and trying more innovative things to improve the standard intake and exaust systems. After spending last night and this morning scourging the 16 pages of the "General Mechanical" forum i've come up with the best near standard cost effective way of keeping an old motor on its toes. I spent 3 hours this morning rectifing and readjusting the old girl. I will attempt to convey some important information for noobs attempting to race their standard 4A-FC motors when the money just ain't coming. *to be continued...

I'm not entirely sure what the people were thinking when they designed the 4A-FC. Damn it is a hideous motor.

I'd dare say your timing belt is out a few teeth.

That picture is of a left hand drive car. you can see the brake booster is on the opposite side to where it should be.

the one on my spare tacho cluster is green 356. i have a '90 Ae92 Seca CS. If you think it would fix it I am sure keen!

boobs! i like em! that intake would probably more restrictive than anything.

i've got a 4A-FC, i had a 2inch exaust fitted from the resonator back with a good quality Zetti cannon. Sounds like a RubarU. The exaust on a Seca 1.6 is 2 inches from the flange to the resonator and 1 1/2 inches from the resonator to the tip, which is poo. I kept the standard manifold. I gave the exuast ports a grind and polish and did the manifold to suit. It now breaths a lot better at the top end. Considering these motors were manufactured with a mere 76 kilowasps its almost trivial spending any real money on them. I payed $270 for the cannon, $130 to have the exuast and cannon fitted and $10.50 for the flange rings when pulled the manifold off.

I had a RWD 4A-C in a AE84. Have you ever changed the timing belt? I did. The engine would cough at low end then almost boost up to about 4000rpm then just fizz out again. Couldn't get it right. Eventually the the valves burned out and she died. Turned out I was 1 tooth retarded on the belt....

I got a hold of a dash cluster with a tacho in it for my ae92... when i fitted it all sorts of things were wrong because the wiring film on the back didn't match up to the lume I was plugging it into to. That and my speed ended up 15kph out so after 30,000kms I got really annoyed and changed it back. I now find it just as easy to drive with out a tacho....

I bought this Corolla in 2005, I previously had a KE30 2 door with a 4K 4speed, my first car. Then I bought a KE70 4K 4speed for $400, That was awesome. I gave it to my dad and he put a 3T 5 speed in it with a 180 holley. pictured below. After that I picked up a KE84 Spirit RWD with a 4A-C 5speed for $250. I decked that out and blew it up trying to play Initial D. Gave it to my brother for $50 as his first car. The butthead pulled the tough suspension, gearbox and diff out and made $900 on it! Not happy I wasn't! Finally bought the Seca CS for $4000 a year ago. Looking to do a conversion to 20V but not sure whether its worth the work and $$$. This is the Seca to date....

I own a '90 AE92 Toyota Corolla Seca, 4A-FC motor, 5 speed gearbox, all original except for some mild port work, 2" exaust, Zetti 4" tip, King springs, 15" RJ Racing Wheels, sports steering, Bosch ignition, Champion leads, NGK plugs, EFI radiator, modified thermostat, removed Air Con and JVC 4 speaker stereo. *360,000 odo and still going strong... here's when i bought it for $4000
