Hello,

Yes Im new, great forum you have here.

Please bear with me, Im half considering an RB25 conversion of a '73 240Z, except I havent bought a Z or an RB25 yet...

I see its quite a common swap so there must be plenty of people that can offer some advice.

Im wondering if you use the standard Z rear end ? is the standard OEM diff happy with an RB25 pushing power through it ? at what point power wise does it start to moan ?

Presumably the standard RB25 gearbox is used mated to a custom/modified prop.

Thanks for your help

James

James, you'll likely find more answers to these questions at Hybridz.org, where swaps like this are the rule, rather than the exception.
