Thanks, good advice there about the twin set up, I just assumed the twin would get more air in there and thus work better but if not then I'm happy to stay with the single as I'm more familiar with that set up (both my other utes are LPG)

Need to work this out first because I need to source the new manifold and I don't want to get the twin set up if there's no point to it.

I converted the Toyota to LPG soon after I got it in 2000 and since then have been a solid LPG fan. Tuning is tricky and you need to make sure the converter is top notch but I've got a good tuning guy (Hi Comp Performance in Minchinbury) who has lots of LPG experience and (importantly) also a dyno in his work shop. Ive found a lot of LPG converts suffer from running too lean because the conversion shops spec converters that are just too small for the job. They run fine on idle and the highway but when you want that extra kick grunt the mixture starts to run lean which causes all sorts of hassles and inevitably - backfires and explosions. This only ever shows up on the dyno and since we upped the size of the converter on the Toyota ute, reworked the head, re tuned it and added extractors it runs better now on LPG than Petrol, IMO. And the mileage is incredible - 650k to 100lts - and that's loaded!

I just love how all the power is right there cold as soon as you turn the key, no matter what the weather, and no worries about dodgy fuel either. All the fuel burns, no mucking about with kickdown pumps in the carby (the bane of if the original Hitachi carbys on the Datto 1200 as far as I'm concerned).

Happy to hear about anyone else's opinion on this, would like to lock a direction down nice and early!
