hey i have a 00 2.5 and all i have done to it is all the suspension, light weight pulley, intake, and exhaust. what else can i do to make it go alittle bit quicker not using turbo just little up grades until my swap. please give me some ideas. thanks!!!!
If you are going to swap dont spend money on the motor anymore. I doubt you have done ALL the suspension you can. Get bigger brakes and get some good tires.
On my old XT (yes, the wedge on wheels XT), I found that porting and polishing the heads, coupled with a Delta Cam regrind did wonders for the performance of the vehicle. My current OBW has the following installed: CAI using the factory air box and a TrueFlow filter; Borla headers, Stromung track pipe, a Fujitsubo muffler, and an STi short shifter - it runs very well. I just had a tune up (NGK plugs and wires, new coil pack) and have an underdrive pulley waiting to be installed (I'm having it put on when I get my timing belt and water pump replaced next week). It's surprising how well the EJ25 responds to modification, and even if the car doesn't gain a lot of HP, it certainly becomes more responsive and more fun to drive (I also have no desire to take my OBW to the track, although I hear they can make fine auto-x cars).
Best upgrade I did that was cheap and easy was the light wieght fly wheel and crank pulley. Looking in to cams but still researching becouse of NYS emmisions cant afford to run CEL
I have a cobb CAI and it really does nothing other than add noise. Once you open up the breathing with cams and heads, the CAI along with header back exhaust becomes much more effective.
I'm no expert, just an aircraft technician, but unless your altering the CR with the forged pistons you not going to gain anything accept the piece-of-mind that your pistons are ready for a turbo, extremely high compression or some big RPMs.
I'm about to start my project which is max power for lowest dollar. Heads are getting pulled i'm buying a $100 die-grinder to P+P the heads and port match them to intake and headers. No good to have flow w/o demand so then comes the $1300 TWE race cams and a tune. You may get a small chunk of hp w/o the cams. Is anyone running P+P heads with a stock cam that can shed some light on that idea?

By itself, though, its relatively pointless.
...Key word in my statement; Little. And it actually does make a difference in the power band.:clap:
Go to i-speed.com and you will see what they offer. You send them your ECU and they reflash it and mail it back based on mods done to your car.
