Lift123, Depends on your budget, i was modding plenty and you can get your parts from monkeywrenchracing.com u can find intakes on the website but just make sure u keep your orders below 1K otherwise u will get hit with like import taxes I have intake, headers, high flow cat - 2'5" exhaust I also have stage 2 cams + greddy emanage ultimate so i dont blow my engine Got aTRD thermostat to lower the running temp. Hard to get the powerfc for a good price nowadays and I dont feel like forking out over 1k. If i manage to find one for a good price I would snap it up though. I recently had a problem with the cams because the car wouldnt rev past 7.2k rpm, I found out that it was a faulty oil pressure sensor next to the VVL solenoid replaced that and now it works a treat. I bought the parts for a full head rebuild with 9.5krpm springs and flat face valves to increase compression from monkey wrench racing. however havent bothered to put them in yet. Depends on what your budget is really though. also a good website is:- http://2zzge.com/library/Corolla%202ZZGE/ that will give u the knowhow to do all works on your car/maintenace where abouts you based?
