Sleepe made 215kw atw on lpg was was pretty much a standard ca apart from a ka24 throttle body and a set of tomei proncams, Joel's is the ca sedan in the first video and he got converted to lpg after going in my ca18det 120y wagon , people underestimate lpg , its so easy to set up and tune and there is no need to retune when you want to upthe boost, it uses the standard computer for spark and that's it, its definitely a cheaper and easier option
