Is your cam timing correct?

This is still going =) Street and track use for 2years http://www.skylinesaustralia.com/forums/in...t&p=2055850

Agreed. 1 of 2 fails. IMO

Good boostcontroller. 4 boost settings possible.

GT4202R ? http://www.turbobygarrett.com/turbobygarre...02_731376_2.htm

We have had some problems with the 1. Generation RB25 (with external coildrivers). Seems like the spark dissappears over 14 psi boost, even lower on big turboed/hp engines. Don`t know if it is the coildriver or coil that is the weak link, but most likely the coils. HKS dli box did not help(as it does on the supra`s) Generation 2 coils seems better, but probably not working with the external amps.

I Would try som other airflow meters.

Hmm but they are both linear 0-5 volt signals.... Is it just a matter of mapping?

Your 1st torque graph looks like your clutch is slipping..

Try this one, I know they make solid ones http://www.catcams.be/800x600/mainframe.htm

They work well on single turbo converted VG30DETT`s Not many of them, thou

I,ve seen 500kw @4 hubs on Dynapack . It was an HKS 2.8 litre.

100% agree

Precision makes smaller exhausthousings for the GT40. This one is A/R 0.81 with 69mm outlet. They call this turbo GT4067R. Rollerbearing core. 750hp rating. 1.5bar/22psi at 4800-5000 rpm with some good cams. I`ll post my dynopaper when done building/ mapping.

http://i69.photobucket.com/albums/i70/tjomi/DSC01157.jpg Was going for the 42, but I chickened out because it scared me unpacking it. Went for littlebrother GT40, and that one even looks too big. The little one is a 600hp Precision turbo! I`ll give the GT40 a try.750hp rating. Wiseco/Crower internals.

The power output of these engines are often a question of fuel quality. Long duration cams will lower compression pressure. Bigger turbos/exhausthousings will lower backpressure. Very high peak power numbers are possible at high revs, because of the short stroke and rodlength/stroke ratio. 500nm at 4000rpm gives 380hp. 500nm at 8000rpm gives 760hp. both with the same combustion pressure. my answer is I don`t know the limits..
