well ive heard kawana auto service (just behind kb auto) used to do work for steve jensen motors when they were an import yard at currimundi, but just servicing and stuff, but i wouldnt go to any1 on the coast for mods, not worth it really, many have tried and failed, and alot who claim to be mechanics for imports dont know alot. u are better off going to as reputable place in bris or goldy. there is one guy named (george may, GMR george may racing) at kunda park , dont know if he knows alot about the rb engine but he knows about the sr20. hes a good bloke hes an engineer, does good work, they do engine conversions and stuff. another engineer is kv's performance in sugar rd, hes into v8's but he does engineering work aswell, hes done some nice cars up. so if u ever want an engineer for anything to get built try these guys.
