Well, i never really thought about that, im on a computer at school, but i have a lot of the shit saved on my computer at home, so ill let you know later. Thats what im hoping with the whole OBD2 thing, just a plug and play and no shipping in and re-flashing or nothing, i should be able to use the teg's ECU right? Well with your '00 si youve got the rear mounts that ive heard are needed for the B18C swap, so thats what i would go with, but its up to you. Im just more leaning towards the B18C anyway, and they both should increase the car's selling value about the same, since they are somewhat close in power output, and i think all the front clips have like less than 55000 miles on the tranny, as least they say they do, you could check i guess if you get the OD with the clip, some include them some dont, and i dont think the ones off of JR do. Ill have to tell you more when i get home, because im new to this, so keep me updated as will i.
