Hey, this is a new one on me but when I went to get my 1992 RX7 Series 6 Efini (ex Japan) insured they had a few engine sizes listed. I had to choose between something like the following:

rotary turbo
13B turbo
1.5 series 6 turbo (!?!)

I was wondering which would be safer to choose because at least the third definition says it's a series 6 whereas the 13B turbo could possibly mean it's a 1992 series 5 (assuming S5s were made in the beginning of 1992 - somewhere in the world at least, such as Aust or Japan maybe). Okay so know I am about to ask a completely dumbas$ question, is there any magical way that when an insurance assessor sees the motor it could be a factory 1.5 and not a 1300cc ? The motor has 13B written on it, so I really, realllly doubt it, but you know how it is insuring these cars, I just want to cover myself so any possible claim is solid. Appreciate hearing from anyone who's ever heard of a 1.5 series 6. It might be for the Australian market because the company that did the insurance is Australian based. Any ideas anyone?

 

Might try posting in the Aussie forum...us yanks don't know much about all the various cool models you guys get.
