Welcome to COROLLA Performance

1996 AE102 Corolla DX

Currently has about 45,000 miles on it.

Oil (usually Mobil 1) and filter (Fram) change approximately every 3,000 miles.  No oil additives used (these products are quite useless despite manufacturer claims).  Do not use PFTE (better known under the Teflon trademark) additives.  Articles on engine additives are readily available on the web.

Spark plugs (NGK BKR5EYA-11) and distributor rotor (NipponDenso) changed approximately every 10,000 miles or when changes are made to the ignition system.  They cost so little that there's no point in reusing them after inspection.  Don't be a cheapskate when it comes to your car.  Whenever I install or uninstall my Jacobs Ultra Team (due to malfunctions), I regap and install new plugs.

High octane fuel (min. 92 rating) used only (usually from Chevron).  STP fuel system cleaner used rarely.

Cooling system flushed and refilled every summer.

Air filter replaced early on with a K&N filter.  Got another K&N filter soon thereafter and put the "old" one in the 93 Corolla. =)

At 36,000 miles, replaced transaxle fluid with Redline Synthetic ATF.  Did not replace filter.  New pan gasket.

Brakes started squealing.  Upon inspection, I found that there was hardly any pad material left!  (my bad)  That was when I looked into possible brake upgrades.  Replaced front rotors (KVR cross-drilled) and pads (TRD HP-Z), rear shoes (euro rotor semi-metallic), and brake fluid (Motul) at 37,000 miles.

Awaiting new Ultra Team and distributor cap (this one is deteriorating) from Jacobs.

Word of advice:  Don't compromise when it comes to parts, no matter how small.  I also swear by Rain-X...magnificent stuff.
 

1993 AE102 Corolla DX

Currently has about 83,000 miles on it.  Maintenance is same as above pretty much, except this car is bone stock other than having a K&N air filter.

4/18/99:  At around 81,000 miles, alternator gave out.  Car stalled on freeway.  Replaced alternator with remanufactured unit from ASE (Alternator Starter Exchange).  While I was at it, changed timing belt, all drive belts, and related seals.  Changed tranny fluid with Redline Synthetic ATF and one quart B&M Trick Shift; new strainer and pan gasket.  Resurfaced front rotors and cleaned and inspected brakes on all four corners.  Oil and filter change (all Mobil 1).  Added Valvoline SynPower fuel system treatment.

Considering Magnecor wires.
 

1992 Geo Prizm GSi (otherwise known as 1991 AE92 Corolla GTS)

Currently has about 93,000 miles on it.  Severely abused by previous owner.  Frame is slightly bent.  Suspension problems results in one side riding higher.  After it was purchased, found out that the engine was leaking oil, so replaced oil seals, gaskets, and while I was at it, replaced the timing belt and water pump.  That fixed the leaking problem, but the engine is still lagging a bit.  Went in for a smog check and failed!  Engine is burning oil.  Holding off on rebuild.  Decided a good tune-up should let it pass for another 2 years.  Replaced air filter with K&N filter.  New cap and rotor.  Magnecor 8.5mm wires.  Previous owner used NGK BKR5EYA spark plugs.  These plugs are too hot, so replaced with BKR6EY plugs.  Manufacturer calls for platinum...now why would I want to use platinum over copper?  Plug wear is hardly a consideration, just replace them as necessary.  Changed oil with Mobil 1 along with the addition of STP Stop Smoke additive as a quick fix.  Fram Tough Gard oil filter.  STP Complete Fuel System Cleaner and 92 octane gas.  Changed coolant.  Replaced transaxle fluid with Redline Synthetic ATF, new filter and gasket.  Cleaned up the engine bay.  You can see the results for yourself:

Amazing, huh?  After a simple tune-up, the car passes!   Emissions are still relatively high, and the car is still burning some oil, but it's good for another 2 years. =)  Look at how hydrocarbon emissions were halved!   At idle, HC went from 201ppm all the way down to 92ppm!  I was quite surprised.  Well, time to mod it. =)
 

1985 AE86 Corolla GT-S Apex Edition

I finally got me an AE86 Hachiroku!  Currently sourcing a 4A-GZE to drop in.  This will be my daily driver/racer while my AE102 goes in for some badass engine work.  My AE family is growing strong!
