I got mine done at Glide automotive on Newcastle street in Perth. They've done my old Silvia in the passed as well (also with Super Hicas).

I will be doing the exhaust at some point but for now I was just looking at increasing the boost at lower revs. Rather than remove the 2 stage boost by grounding the stock solenoid valve, I figured I'd fit a manual boost controller to do the same thing and therefore removing the solenoid all together. I understand the exhaust can take the 7psi doing this but I was wondering if it could take a little bit more - up to say 9 or 10psi. I realise I won't get the maximum benefit from increasing the boost if I keep the standard exhaust, but will keeping the standard exhaust actually cause any problems? I generally don't drive the car very hard but I would like the increased power in the lower rev range. Thanks for your help

Hi, I'm new to Skyline ownership and to this forum. There seems to be heaps of great advice on here. I have a series 2 1997 R33 GTS-T which is completely stock (apart from a K&N panel filter). I understand the boost pressure will be 5psi up to 4500rpm and 7psi thereafter in standard form. If I was to fit a manual boost controller (probably Turbotech after reading the positive reviews on here), would there be any problems running 9 - 10psi and retaining the stock exhaust? I've tried searching the forums but please point me in the right direction if this has already been covered.
