arent they a long stroke, short rev motor, like a 2.5L (the SER?)
this means shit tons of TQ, but a small power band. unlike the hondas, where you get high revs, but lower tq cause of the short stroke and discplacement.
I PERSONALLY, wouldnt do much to the SE-R. you prob have a good amount money and time invested in the EG, and frankly, you and i know YOULL NEVER get what you got in it. Id hang on to it, and maybe if you dont want the kit on it, offer to swap it out for stock pieces, if thats too much trouble just leave the kit on, fuck it.
Theres a lot of mods for the SE-R, but i have never been really impressed with the power they make. Although , charles from Mainstream Performance did a Turbo Spec V that was fun as hell to drive, i think it made like 250 whp and 275 TQ lol.
bottom line, its a NEW CAR, that is under warranty, which means drop it and put some nice wheels on it. and leave it alone......at least for now.
I would put money in the hatch, you need VTEC and B16 pistons

or a 100 shot
