Stage 3 big valve head is must as stock valves bottle neck at around 250bhp, Newmans cam i'd agree with but not double valve springs they specifically say not to use them! Even a Stage 3 T3 (48/55) would not flow enough for 300+bhp i'd look at something bigger! Dont know what 803's are good for. Pistons, rods, yup and arp bolts to hold it all together!

and my turbo is a stage 3 t3 and that is managing fine with 300.
Agree-bottom end must be steel rods and forged pistons though!

Interesting! Where was it Dyno'd?
NMS and APT have both told me that the standard valve size become restrictive at around 240-250bhp, and a Stage 3 T3 is only rated to 280bhp max!

standard valves are already big to start with mate,also i know a few people running st3 t3s running 320hp its a very good turbo,you can get the mahle pistons machined for lower comp they will run 350hp,but change the rods to steel,then you will run into gearbox issues if thats standard

mines a s1 head which i believe had the better valves to start with so maybe he was refering to a s2 head?

Stage 3 T3, 320bhp?
You DON'T know a FEW people with 320bhp, well, not on a CVH anyway. Not a PROPER 320bhp.

Ok perhaps some people believe it is possible........... maybe it is at an extreme push? Maybe some rollers say 'X'bhp and other 'Y'bhp.........but lets just say that it will be easier, and more reliable with a Stage 3 head and a bigger spec turbo, I think thats the best answer!

do agree dyno's are so out that they should only be regarded as an estimate of the power, things like ambient temps, barometric pressure, all play a big part.
