With a big shot of nitrous and low boost I'd imagine you could go a very long way

I mean the same type/size turbos as the car left the Nissan factory.

Your N1's sound cool though!

i have [email protected] running 1.35bar. could run 1.4 for a bit more power but i went with dano's recomendation and stayed with the safer 1.35.
Not sure what that would be at flywheel though.. maybe 480-490?

I have just over 400 with an Impul ECU and decat. The power and torque curves are very good and it feels that way when driving. Not much below 4000 but climbs smoothly up to 8000 and I leave it there.

I would like more but the car feels bombproof and I don't think I would notice another 50 for fast cruising which is all I do.

Pintio,

So what spec is your engine, (apart from the stock turbos), to see ~480-490?

Manifolds, cames etc etc?

Many owners enjoy exchanging notes on how you can squeeze out hp from any Skyline engine with little or no expenditure and with day to day reliability.

you are running .05 of a bar boost less then me but have much more fueling going on and cams and it seems you are running at a guess in the region of 30-40fwhp more then me..

That's really nice Mikster.

Hopefully I hope for something similar in the new year, the only difference is I currently only have 555cc injectors. They may have to go if they are my limiting factor though.

theoretically your injectors should be able to flow upto 550ish flywheel hp. if you are running standard turbo's even if uprated i dont believe they would max your injectors out.
