Several racers used that engine in the Heart of America series ....... They ended up 1st and 2nd, but the guy who won the series could win with almost anything.

Hi Grenade10 thank you for the reply, I think this engine is a great choice and we can source the parts cheaper then the Nova Rossi and Reds parts

P/L/R assembled for AU$91.64

Not a high dollar engine but has anyone tried the new Reds R5r in a GT yet?

I just got one with the 2069 pipe and XS header. What do you think?

Regards
BM

It works pretty well. Not the power of a modified Ison, but it will hold it's own. Just keep the temps down, was thinking it could use a larger head, like is on the Team version.

Modifications are allowed. As long as the engine still conforms to the rules.

Hey Grinder I finally put a gallon through my ISON. What is your lead time for a port? Thanks.
