lol man its all in the tune, if ya running standard turbo ecu and injectors aslong as u have a cooler ull be safe with 10-12psi and theres no need for a decomp plate ect leave it hi comp and it will come on to boost quicker, just make sure u are running a genuine nissan head gasket or an mls otherwise that wont last long

A bigger exhaust will help prevent pre-det as well. Mines on 10 without a cooler, does ping sometimes in 3rd, not to worried about it because it wont be there for long. Much luck in your conversion! haha

70psi easy, but you need twin turbos with 35psi from each.

Duke wouldnt that still only be 35 psi? and mate i had mine running 14pound with no cooler and a 3" exhaut made 200rwkw on a standed na bottom end no decomp plate standed ecu... howeverrr my waste gate eventually siezed and i fed the turbo some piston peices :/ soo as long as everythings in good working order then 7-14 isnt out of your reach Some original photos have not been recovered yet.

haha maybe ---------- Post added 22-03-12 at 18:02 ---------- If you put factory turbo injectors, turbo ECU and a turbo fuel pump in it, capable of about 10-12psi without before you start running out of fuel. This means you have an exhaust, cooler etc etc

i reckon 25psi. make sure you set your intake manifold timing to 75 degrees retard(facing north) to help stop pinging. no cooler needed.

Make sure u run standard unleaded and not premium open ya spark plug gaps up to 1.95mm and a little trick I learnt in the trade is turn ya dizzy 180 deg but swap at 3 and 4 spark plug leads.... Now to get the most out of it u need to leave the brake vaccume line off to give it a vac leak...now the next step is vital take the waste gate hose off and remove the throttle spring.... Hope this helps
