'88 NA 100k Tune-up

[poplifedc]

I have a 1988 MR2 NA 5speed that is approaching 100k. Everything on the engine is original except for the spark plugs, wires and muffler that I had to preplace twice in one year.

At anyrate, the oxygen sensor bit the dust and has bonded with the pipe it is attached to. With that it's time to do some updates.

My questions is, where can I find performance parts for this engine? I want to replace the hoses, water pump, timing belt, oxygen sensor, and I'm looking for a nice after market header for more power.

In a few months I'll be upgrading the suspension and brakes so I'll be looking for some aftermarket upgrades as well. But for now, I can't seem to find much on the MK1.

Thanks.
