i have an h23 bored .020 over sleved and low compression pistons 9:1 and i am wanting to boost anyone who can help that would be great. i was wondering how much boost i could run? and how much boost if i have a 50 shot of N2O or if i should take off the N2O?

 

if you are properly sleeved , you can run whatever horsepower // psi you want. Be realistic though. The weak point now is switched from your block/piston to your fuel/ignition. Many people run your block setup to 500-600whp on pump gas and stock ignition .. on Boost.

 

would it be recommended to get a programmer to adjust the fuel and what is a good one.

 

i'm running Hondata s200 with p72 ecu .. that is my 'programmer'. Your tuner would take care of that part, all you need to do is get a Fuel Pressure Regulator and a Walbro 255lph fuel pump and install. Get a base map for your setup and drive to tuner. He will take care of the rest.

Do you know how much this will run you though ? .. Do you have a turbocharger / manifold, or not yet ? .. a decent setup will run you a few thousand + cost of labor if you're not installing yourself. Boost is no joke, be prepared.
