Ivan, as long as you get an engineers report and comply with our ADR's (Australian Design Rules) you should be able to. I'd call Just Cars, (will insure up to market value only which is $5,800 for a 240) these guys are into high risk heavily modified cars. Famous as I mentioned above are lenient too and will offer you agreed value (definately give them a go). MB Prestige might insure you but I'm not sure about their modification policy. I've just called "Street Tech Modified Vehicle Insurance" who is a part of the Heath Lambert Group. I've not had to deal with Belinda before but I think that they might give you some form of cover. She's going to call me back later today so I'll let you know what happens. If all else fails Ivan you might need to go through brokers but that's a last resort. There's a guy from Perth (name escapes my memory atm) with a nice RB powered Z. Ask him how he got insurance if he does have any.
