radiator fan upgrade

[dumpycorsa]

Hi. I'm looking at replacing my rad fan for a pacet/kenlowe type. I'm using a standard nova sri rad with an 20xe engine. Whats the largest fan dia I can use on a standard rad and is it best to fit it to the front or the back of the rad (set the fan to suck or blow). I'm a bit tight for space at the back of the rad as I'm using a BTB manifold. Any sugestions would be useful. P.S is there a bigger replacement rad I could use instead ie nova TD rad?:thumb:
