The EP3 generation Civic Si was built at Honda’s UK Plant in Swindon, England. While the K20A3 engine (sourced from the base model RSX) doesn’t rev as high as the EM1, it makes up for it mid-range torque: VTEC kicks in at 2300 RPM instead of 4500 RPM in the EM1. In addition, peak torque is increased by 20% over the old model
The K20A3 engine features Honda’s latest i-VTEC system, which is an evolution of Honda’s iconic VTEC system from the ’90s. i-VTEC performs the same function as the old system, allowing a more aggressive cam profile to kick in at 5,800 RPM. The difference is that i-VTEC uses Variable Timing Control (VTC) which can vary the intake camshaft phasing throughout the entire RPM range (not just at 5800 RPM)
The all-aluminum K20 engine family replaced the famous B series line of engines. The block features iron cylinder sleeves for durability, as well as a fully counter-weighted forged steel crankshaft, strengthened connecting rods, strengthened cast aluminum oil pan, and main caps that feature ferrous-carbon inserts for added strength. The lightweight 11:1 compression pistons are cooled via piston oil squirters. The K20 is a square design (86mm bore x 86mm stroke), giving it an ideal balance between high RPM operation and low RPM torque
Handling is substantially improved over the EM1, despite ditching the racing-derived double wishbone suspension up front for a MacPherson Strut (shared with the RSX). This new strut design allows for longer control arms to better maintain suspension geometry during heavy compression (hard cornering). More importantly, the EP3 is 95% more torsionally rigid than the EM1 Si it replaces. Overall, this car is much more chuckable and has considerably more grip than previous performance Civics
Key Model Year Changes:
First year of the larger 16″ 5 lug wheels (previously 4 lug)
Updated headlights and taillights
More aggressive side skirts
New silver interior trim
Rear sway bar is increased to 17mm (from 15mm)
2004+ cars do not have the transmission grinding issues that the ’02-’03 cars are notorious for. A transmission-related update was made to address this across several Honda cars in 2004 (such as the 6spd AP2 S2000)
2005 cars have the VIN embedded within the ECU, which can make it more difficult to pass emissions testing if modified with Hondata
The EP3 generation Civic Si was produced from 2002-2005 in hatchback form only
