Has anyone had this done, what's it like ??

Is there that much difference in performance/driveability between 350 bhp & 400 bhp - I guess there will only be point something of a second to 60 but what about to 100mph

 

It,ll be the torque too i,d imagine, make the car pull alot better through the rev range etc..

 

Contact a member on here known as 'gussy'. He's had this package fitted to his Spec C Type-RA. He rates it very well, with the turbo spooling up only few hundred rpm later than stock.

 

Did not have mine done by Powerstation, but oh yes speaking from my experience! Don't know what Powerstation Stage 4 is but chances are you will be running a full decat (if you aren't already), poss bigger turbo, exhaust headers, poss FRMIC and ofcourse a remap.

Its not just about going up 50 bhp, but also keep an eye on the torque level.

 

I have it on my spec C. I've had the 'stage 2' (Miltek and remap) from 1000 miles and its definitely an improvement. There's not much hike in torque (if any - talk to Rich and he's up front about it) but 300+ lb ft is available between 3.5 and 7k. See here for my graph.

The car feels a lot stronger. Once its really on boost it just keeps pulling right up to the red line. I don't know what this means in terms of real times but I'd guess .1 0-60 and .2 or .3 to 100.

Modifications are new injectors, new air filter, new turbo and inlet hose. The Miltek sports cat remains the same.
