Dr Z, What you know that we don't? You seem to have lost your objectivity yet again. Quick to praise APS, quick to knock others. No one besides Nizpro currently knows the full attributes of the power delivery. I do have some information, and it is nothing quite like one would normally expect. Brian I wouldn't expect the power delivery to much different to the Nizpro stage 3 kit. I mean 1000hp at the engine would be about 750hp at the wheels, the stage is good for about 500rwhp and mainly because the turbo runs out of flow. So you would need a bigger turbo, better exhaust manifold some higher lift/longer duration cams to suit and maybe some head porting. Taking into account that the engine would presumably be running on a motec, which would help the lag of the bigger turbo, I think you would find the power delivery to be very good.... also I think that all those APS flag wavers should be issued with a little APS flag icon under their name so we all know to ignore their comments on anything other then an APS product Dave. I would think a 4.0ltr engine with a big turbo will have no problems being drivable. There is very drivable 3.0ltr Supras, drivable 2.6ltr GT-R's that put out that much hp. Can't wait to see final specs etc on this engine APS V Nispro is just awesome in my eyes. Some of the debates on this board about it get out of hand but in general, look at it... without Nispro would APS keep pushing the limits of the engine as fast as they are and vice versa? Makes a win win situation for the public to me
