I really don't get it... you are running a high-compression naturally aspirated engine, and all the sudden a chip, a tune, and some exhaust system overhauls are going to drop your cars stock mid 6s 0-60s to 5.0 (what STOCK evos run!)? I'm sorry; but that simply does not happen on NA cars. You'd be hard pressed to do that on a TURBO car, which almost always respond better to mods than a NA motor.
The Integra Type R is probably the best handling FWD mainstream car ever made, but let's not go off the deep end with these "oh I chipped my ITR and I'm smoking modded Evos and stock Vipers all the time" comments. You are soiling the name of a great car.
