I'm planning to run on gasoline for now
BTW I'm not changing the cams yet.

The most you can make with those injectors is around 300hp at the tyres.

What kind? octane value available at the pump in your area?

Cams will help to achieve higher output, but the N/a cams maybe aggressive enough.

Thanks for the reply. The octane at the pumps here is about 93. Maybe later when I accumulate the money I can buy cams.

Does anybody know what would be the best turbo for fast spooling. I'm planning on buying a turbo from Turbonetics, they have good prices.

[RT40Corona4AGTE]

Turbonetics GTK series, possibly the 325/350/450 or the like. http://www.turboneticsinc.com/gtk

OR

Precision Turbochargers make some good units.

Change to a 0.63A/R turbine too for what you are doing. http://www.powertune.com.au/precision.html

Decide how much power you want and what you want to use the car for.

Then choose a turbo with an appropriate power rating.

The turbo you mentioned will have good spool.
For better spool a GT2876R would be the best bet and still be able to make 250-270kw atw.

You will def need bigger injectors. around 600cc or even more to have head room.
