Hartge has a two models:
Hartge 323i RS and H35 335i:
323i RS: The 323i RS using the 2.3 litre K-Jet M20 power plant and the H35 335 using the 3.5 litre L-Jet M30 from the 635CSi , clearly based on the stock 323i Hartge modified the cylinder head, fitted a faster camshaft and a exhaust manifold and exhaust system with better flow. A trunklid spoiler, decent badging and a leather Hartge steering wheel made the car look sportier. And so did the ASS sports seats in Hartge style cloth. Handling improvements were a 25 mm lowered suspension combined with Bilstein gas pressure shocks, 15” BBS alloys with 205/50 and 225/50 tires. Optional was a set of 3 gauges including oil pressure and oil temperature to be fitted on top of the dash.
