What kind of setup are you going for?
My old man got Gas Injection in his caprice from Smithy's in Bayswater on Barry St they did an awesome job on it looks great.
Go to Addicted Performance in Hallam.... 97086232. They built and tuned some big power gas cars... for example the record holder of the gas vl scene(10.35). also another 2 vls with 315kw (lpg.747 - 10.9)). All 10s cars. The tuner is a gun with gas. They are certified gas research dealers and fitters.... Unbelievable workshop and have got full dyno (very tight and accurate) and soon to have engine dyno. They are forever expanding and are well known to have quality cars. Everytime I go past to see them about my car they have show cars that run 8s. That has to say something and personally my car has never run better. The combination of Danko the owner(V8 specialist) and Ben the tuner (Turbo Specialists) they ARE the best team. You won't be dissapointed...
