There's some good info here. Not sure if you've checked it out yet, but it might be a good starting point.

I tested some 98/99 red Denso ones and the consistently gave 190cc/min.
Too low for me so I fitted green densos off a Toyota 7MGE

Are you sure they were Denso, or were they keihin? Curious because I'm running the same injectors and I thought there were 240cc/min.

Thanks,

No name on them but they do appear to have the denso logo. At least that is what I think it is.
These are the earlier mikuni TBs which are quite different to the 2000 on.
