I am really tempted to go for a v-cam. My view on all the data looks to make an ideal street set-up for the low to mod range power. The question is if you are not chaising big numbers and you dial say mild cams in and keep the boost down , with enough ignition advance can you get the same effect from the very low off boost revs to the 4k mark ?

No!!!!!! Get a good pair of 2510's n spend the rest of the money on brakes !!! Dont waste your money

Unless that is 500hp at all four wheels and not a flywheel number on -5s, I would be spending money elsewhere on the engine as you are not getting the best out of the turbos.

It will make quite a difference but it's hard to motivate the huge cost of it...
I'd rather build a rb30 than buying a vcam. The only reason I have it is that it was on the car when I bought it.

From the research I have done on the higher power cars it's not as effective unless you have the high lift version . If standard cams are advanced can this have the same effect , and then use the bigger turbos to give the mid to top range.

With the advent of aftermarket ECU's with better processing power/strategies, it strikes me as odd why we just dont all swap our 26 heads for VVT 25 heads and have ECU control the cams??
Obviously theres a good reason for not doing it or it'd be a common sight. It'd be like having factory V-cam...

abit of work involved tho

manifolds dont fit, so that needs to be sorted.
and im sure switching heads changes the comp ratio

i think the v-cam on mine will limit me as its stage 1, so may in the end just get the pro

Its worth it i think, seeing the difference, though mine is a 2.8.

depends i guess on the deepness of pockets and what you really want out of it.

tbh i would spend the funds elsewhere on brakes/suspension etc

The link g4 will run the vcam, I think some more viable alternatives to get variable valve timing should be investigated , it opens up another era in gtr tuning. Given the new ecu's
