as an owner of a 2002 323F BJ with the 1.6 ZM-DE engine, I'm interested in questions about a ZL-VE conversion - at first, only theoretical, because in Western Europe, nobody seems to have done that yet. From what I've read, the Maztune guys here seem to know about it.http://www.protegefaq.net/
says that the ZL-VE head is a direct bolt-on to the ZM-DE block. Best of both worlds would be then using the european ZM-DE block (compression ratio 9.7:1) with the ZL-VE head and the euro ZM-DE intake manifold, including VICS, and the ZL-VE 4-2-1 exhaust manifold instead of the stock 4-1. I would keep the gearbox, because the euro version has shorter ratios in 5th gear and final drive compared to the JDM/USDM Version.
Main problem will be the engine management/ECU and harness, I think, to make everything working together, especially fitting with German emission regulations and vehicle inspection certificate (nearly impossible, I think) and getting all required parts (the ZL-VE is quite common in Russia, but I've no connections there).
So everything is merely a game of ideas.
For example, what I don't know is if the ZL-VE has a catalytic converter. The euro ZM-DE has the converter directly bolt on to the exhaust manifold, and so I think it wouldn't fit to the 4-2-1 "header".
Do the ZL-VE equipped cars have other modifications (brakes, suspension etc.)?
So, if someone here would share his experience, many thanks.
Sorry for my English...
