G'day fellas

Im going to be doing some work on my dad's '93 econovan 2.0. the plan is to hot it up a bit so it can tow his boat easier when he is touring in it. the van runs 99% on LPG but needs to be able to run on petrol as LPG isnt always available in the country. I was thinking upping the compression may give it a bit more poke with the LPG. here are the engine specs..

Type - 4cyl 1998cc
bore x stroke - 86x86
compression ratio - 8.6:1

what compression ratio can you run on standard ULP? as most of you know this is the same engine as is used in the telstar/626. it can be stroked to 2.2, but this isnt favourable as the bottom end only has 100k on it and doesnt really need a rebuild. what other types of modification can i perform to the head to give it more grunt? I plan to port it, will this give a noticable improvement?

cheers fellas.

Head porting, if done right can give good improvements. How about running premium unleaded in it when you can't get gas. This way you can go up a bit higher again with comp. and still be safe. All engines vary, but on premium a ratio of 9.5:1 should be safe, but as with the porting, you might have to play with fuel mixtures and ignition timing.

i run 10.1:1 on ULP
