mods
If you want to make your gsr's vtec pull like a preludes. (which is nice). Get a skunk2 intake manifold and p28 chipped ecu. (go for 5300-5800 vtec engagment). My first gsr has skunk2 im, aem fpr, 5600 vtec chipped p28, apexi header, testpipe, oem itr exhaust, msd ignition, msd wires, iridium plugs, iceman cai. The only adjustable thing was the aem fpr, but at the dyno I got 179.03 hp. I was gonna get hondata and add ctr cams. But sold her. Stock internals with 112k. Maintanance is a big issue, Point is my quarter was 14.4 when I added the si tranny, skunk2 coilovers, and falken azenies on gsr swirlies. I could beat my friends 93 stock cobra and his 04 wrx on the highway. Off the line, not a chance. Since those mods I only lost to a T/A. I raced everything out there. But if you get the skunk2 im, you need a p28 ecu otherwise you'll get check engine light, and since the skunk2 im is a single ported runner, you need a single engagment vtec rather than the gsr's dual. And if you use a intake, buy one made for a type r b/c the gsr's wont fit no-matter how much you try.
