LPG conversion of an R170
I'm starting this thread to let members know how I get on with converting my R170 type to run on liquid propane injection. (Lsi)
The kit is made by "Vialle" . Based on BHP/KW, the SLK 230 needs the largest injectors (brown) and the larger pump. I'm installing a cylinder style, multi- valved, single-hole LPG tank. It's 300mm. diameter and 863mm long and had a gross capacity of 55L. This means a useable LPG volume of 44L. I hadn't realised that the R170 model has a far smaller boot (that's trunk to you U.S. guys, LOL!), than the R171. To accommodate that tank and to still allow for roof retraction, I'm having the profile of the floor of the boot/trunk modified. It has to be lowered on the left (above the silencer) by about 50-75mm. It would appear that there will still be enough clearance for the silencer. We'll see .... The filler nozzle has to be located in the rear bumper. It can't go behind the petrol-flap because that doesn't conform to U.K. requirements. There'll be quite a bit of welding and head-scratching to fix the floor and the tank-frame in place! The spare-wheel will be lost but there will be a small storage area to the rear of the tank. I have sourced a strong luggage-rack that fits onto the boot-lid for those holiday occasions when luggage needs to carried. It's rather costly, though, at ~ Ł250!
I'll NEVER recover the cost of this conversion (unless I keep the car until I die and do about 80,000 miles, but do I care? I just love mechanical projects and technology! Lsi IS cutting edge!
