Question for all 2.0L looking for performance upgrades for your engine. What can I expect from the 2.0L which pumps out 118 hp after the following: 1. Port and Polish the head 2. Hone and extruded (or however you call it) the intake and take a couple of mm of the inner surface to increase the airflow 3. Larger throttle body 4. Custom Pistons to increase the compression ration from 9.2:1 to 10.x:1 or higher. 5. Maybe the exhaust (or is it the intake) cam from the J-Spec 2.0L (I heard that the 2.0L is not a direct fit for US 2.0L cars) I can get get a head for like 200 (I don't want to F' with the head in my ride yet). What types of prices would Lik be looking @ for services like this?? Any type of info would be VERY much appreciated. Thanks

well I am pumping out close to 130 with header intake and exhaust and this is dyno testing right here were did you get that information from and also I have heard the same thing about the j-spec exhaust cam from a mazda mechenic.

Is that 130 at the wheels or crank? Dan

I do belive that is at the wheels but I would be more then glad to get the car dynod again and let you know on it I will have it done when I go the drag Strip this thursday Night.

Do you have dyno results, either a scanner or perferably the actual dyno results source file? I would like to plot them against my "baseline" results to see changes. Bryan Pendleton >

John, take a couple floppy disc and get them to copy the data files on the floppies. It only take one disc, but just in case one is bad, you have a backup. Enjoy, Bryan >
