Exhaust manifold porting.

http://www.jperformance.co.uk/nissan-pulsar-gtir-sr20-n14-cast-iron-turbo-manifold-p-668.html this was the one i was thinking of ...

I'm running a 2871 turbo currently at 0.9bar...pushing 320bhp...Bob have squeezed every drop of performance possible out of her. Manifold holds fine currently but as pointed out its not serious power (just yet)
Once the power FC unit is fitted and mapped and we find 1.6 bar...then we will see what happens to the manifold
I'm all prepared to replace it and the turbo at some stage!
(quite soon maybe)

tho....the car was running a stand alone ECU at some stage in the past on that manifold from what we can work out...the boost was somewhere around 1.2-1.4 bar at a guess...but it was running lean once the ECU was switched over...so might be really lucky with the manifold if it has survived??? who knows!!!
