Stage 3 T3 with a .48 exhaust housing (should come with that at that spec.).

Change the chargecooler for a front mount intercooler as they suffer very badly from heat soak - when I got my car mapped Ahmed wouldn't do it at first until I got rid of the chargecooler as he said that trying to map it with one of them is like trying to take a shot at a goal that's constantly moving!

The rest of the spec. sounds good, if you're running OFAB management you should be ok for what you want - get it to Grove Garage for mapping

Also - I'd recommend an AP paddle clutch, don't get an Alcon one as they're pony from my own personal experience.

A Bernie stage 2 box would also help you with launching (Quaife diff) and obviously hard engine mounts to stop the dreaded bonnet dent!

Cheers,

Andy
