Difference between a 01/02/03 DC5R

[Non Vtec]

there have been a few changes internally in the gearbox and with the oil pumps in the motor.. the 2001 had a design fault in the oil pump which caused a few of the to die early.. not all of them had the bad pumps but a few have had them..
The gearbox has had a few various parts revised due to faults being found in most of the markets, with service bulletins being put out in the states.. I beleive this was only an issue with a few of the 2001-2002 models and was fixed early on aswell..

I heard somewhere there was a difference in Valve springs between the 02 and 03 model. Thats what i remember off the top of my head. Possibly off ClubRSX
