Don, your ideas on the lite mani can be applied to both donks & the donk lean negativity is a bonus.
So they where a bit of & deserved to be treated as such. The LZ18et, LZ20et as you would know is a loosely coined term for L cranked Z18et not official so rest assured I will sleep well at night if I insulted a rare owner of a "real" LZ. Just good Hybrids for different strokes and purposes.

LPG has its issues yet when setup properly you get 10-20% less hp than EFI but more than 100% economy.
Stu, seems GR throttle bodies have their share of issues for tuning with all brands of converters?
If there is a cheaper and easier EFI setup I will never steer anyone away from it. The only standalone setups I know of are the Vapour inj units http://www.profire.com.au/ and JTG icon for liquid phase inj http://www.alpgw.com.au/Products/Systems/JTG-Liquid-Injection.aspx
Also some folk have an MS LPG setup (Cletus Racing in Oz?) & some other one somewhere on the Megasquirt forums.
