I'm planning to do an RB25 swap into my '81 ZX sometime fairly soon, and was wondering about the mounting. I've seen someone who said that they used mounts from CxRacing but all I could find there was the S30 RB25 mount kit. Would that still work with the S130? Or is there a better setup? I've also seen people talk about using the R31 engine mounts with the stock S130 tranny mounts.
