LPG Conversions

Holden Chev Suburban V8.

System type: Vapour injection. No discernable difference in power between gas and petrol. Seamless change over. Indirectly controlled by the cars own computer so that there is no conflict and all features are retained (e.g. traction control). The suburban has its petrol injectors inside the inlet manifold and plumbing going to these. This makes for a few challenges and limits how we can fit LPG injectors but it is possible.

Cylinder: 106 litres of useable LPG in two cylinders mounted under the rear in lieu of the petrol tank. These are a shorter fatter cylinder closer to the rear axle and a longer skinnier cylinder behind that. This leaves room for the shock absorber and the exhaust and there is no effective loss of clearance. With a towbar it looks great. We fit a single flat plate under the tanks so there is just a sloping flat area visible.

Petrol: A new petrol tank of just over 100 litres capacity is fitted under the centre of the vehicle.

Controls: Built into dash as per Photos.

Filler: As with all our jobs, if it is possible to fit the LPG filler in with the petrol filler then that is where we locate the filler, that is the case on the Suburban trucks.

Disclaimer: We endeavour to get all our data correct but we do not guarantee that we are perfect and havent made an error in some of the data.

With the injection systems we do change the brand we use where we can improve on the quality of the equipment fitted. We are not tied into one particular brand and we are entirely motivated by self-interest; we arent compensated for the labour to replace parts under warranty. When we fit components we dont fit them for ease of replacement but for best performance and l ooks and then within the requirements of the standards.It is therefore in our interests as well as yours that we dont have to replace parts and so we make sure we fit the most reliable, long lived parts.
