hi i hope someone can help,my car is only ruuning greens but under inspection it turns out the car is running a newman bd14 inlet cam and standard exhaust,my qustion is would i be better of replacing this cam for a standard inlet and would i also need to change the double valve springs?hope someone could help as for the power im running is the bd14 a bit much in your eyes?the turbo is a t34.63 the head has been mildly flowed and bottom end has valve cutouts but hasnt been low comp.the car feels really really laggy

As a general rule of the thumb in most scenarios the standard exhaust cam along with the modified, in your case BD14 inlet cam.

But standard cams are good for like 400HP, but as you have porting work it may be of benefit to you.

The exhaust housing you have won't help, it will gain you more power than a smaller one but the pay off for this will be lag.

Imo I should think your injectors are on there knees as well, I would have thought Bosch 403's for your spec or better still the Siemens 55LB, but then as I say thats just an opinion, it would be impossible to say for sure.
