Even with the TRD supercharger on my 03 Corolla, I still can't get over 200hp
. I do have the fastest Corolla around though, lol. Everything on there is all street legal through TRD (for those of you who don't know what TRD stand for: Toyota Racing Development). Hence, my CF name. DC Sports just came out with Street legal header for my car (FINALL). May get that next. I need that high flow cat by Magnaflow plus a new wideband O2 sensor. I've got about 1.25" drop all around which makes it look so SICK, especially with the stock aero kit from Toyota. I'm looking into changing out my TRD exhaust in a few years to like a Flowmaster system. THey are the bomb and so agressive sounding. I had one before on my Altima. It's got huge glasspack on there and it does wonders. I don't have intake, but if I do, I'll probably need water injection because I heard the intake + supercharger will run too lean and the cat convertor will get messed up. I don't know if I will mess with that though.
I would love to get my hands on the SRT-4 especially the Stage 3 kit, OMG.
