I have a B16a1 w/ the following in my 88 CRX HF

ITR cams
ITR valvesprings
OBD0 - OBD1 conversion
Chipped P28 to DOHC
V-AFC.
Blah blah other bolt ons...

I want to add CTR pistons to the motor. With the 11:1 compression, how would this car like the 80 shot of nitrous? I am only considering Direct port. I have used zex and I know it is a beginer system. I want some serious power.

 

itll work great , just watch the fuel and youll fly,

 

i would get some fuel upgrades ie fuel pump, adj fpr and a fuel rail and hit the dyno for some tuning

 

That was the plan all along. A walbro 255 and mabey some bigger injectors and off to the dyno.

 

You don't need bigger injectors to run that setup. If you go direct port just make sure to get a bigger fuel jet to help add the extra fuel while squeezing. The direct port is going to be harder on the motor, so keep that in mind.

 

dont bother w/ injectors or higher fuel jets. just get it dyno'd and find out what 80hp really equates to jet wise. if your going to build the head, jump to a 100 shot. id invest in an ignition..ie msd digi 6! by far the best for ur application. its got a lotta features especially suited for n20 and drag racing. if ya need a digi 6 i gotta sell mine so let me know, pm me if ya got any ?'s or need a new nx kit cheap.

Hey can you tell me the jet sizes for a NX 80 shot? I thought 100 was the smallest, but maybe 80 is. Thanks, 100 was 26/14.

 

80 is only available at lower fuel pressures...so this would require a second fuel system.....
