Please NOTE this is MY opinion... and MY opinion only.. so please dont take offence....
The EVO 4 firstly corners and handles ALOT better.... Cornering is AWESOME.. haveing the 4wd you can basically just accelerate all the way around and through a sharp corner....
Throttle response is snappier.... and the evo 4 revs a little harder... althought my r33 had better throttle reponse over 180.
Te Evo 4 feels ALOT more stable on the road.. especially at high speeds..(over 160....I had the car up to 220 today and the car just sat flat, smooth and safe....were as my R33 seemed to drift alittle at high speed.)
What I'm comparing here is my old R33 which had
FMIC, SAFC, fuel pump, custom dump, HKS super drager xzorst, hi flow cat, apexi pod.....
and
My evo 4, 3 1/2 inch custom stainless exhaust and dump, heavy duty lower springs, BOV, air intake.
My R33 made 270hp at the wheels as alot of guys here know... and for a r33 that will run a best time of about 13.7.... my evo 4 with its current mods plus a new ecu and air pod upgrad will do low 13's.. and once I put a vf22 (sti) turbo on it (which only cost $1400 as apossed to expensive garret turbos for the nissan's).. my car will be easily into the 12's.........
Please again this is my opinion only ... I do not want to offend anyone.
