Have it remapped at 7000rpm. look at the dyno graph and see if it still pulls at 7000rpm, if it does then up the rev limit to 7300rpm, will probably get abit more out of it with a mantzel inlet as they like to rev high.

It was probably a 115bhp 2.0 8v, not the 130bhp SRi engine.

7300 is a bit too much for standard rods though?

Rods should be fine upto about 7500-7600rpm, anything more i would prefer something lighter and stronger for less resistance. Aslong as arp's are fitted then wudn't be a problem.

I would say around 145bhp, depending on what your after whether it be low-mid range or top end power, to gain anymore i would have headwork done as well, it will make the cams so much more effective.
