i have a Semi-Built B20/Vtec that pulled 216hp 152tq(need to redo exhaust). Was thinking of tring a 50-75 shot to reach 300hp, but are VERY weary of the stock sleeves, heres my set-up:

B20B
Bored to 84.5mm
Eagle Rods w/ ARPs
JE 12.2:1 Pistons w/ rings
ACL Race bearings
Golden Eagle Blockguard
Cometic .051 Head gasket (around 11.5:1 comp)

B16a2 Head
Ported and Polished
Skunk2 Dual Springs
Skunk2 Retainers
Bronze valve guides
Skunk2 Stg2 Tuner cams
ABES Manifold
Skunk2 68mm TB
Skunk2 Rail & FPR
RC 310cc injectors

I want to tune the nitrous in using my hondata s300. Any info appreciated.

 

It's all in the tune. I've seen B20/V's out there pushin 15psi and makin 400+ to the wheels on stock sleeves. The key to reliability is a proper tune. Oh yeah and don't spray before vtec. Also compare your build to some builds in this thread https://honda-tech.com/forums/all-motor-naturally-aspirated-44/%2A%2A%2Aofficial-all-motor-stock-sleeve-b20vtec-thread%2A%2A%2A-1555476/

 

I sprayed before VTEC....A LOT....what exactly is supposed to happen because of that?

 

Honestly, I'm not sure. I've just been told by countless people not to cause they've had bad experiences with it... And to be realistic, I've seen other people do it. Guess it just depends on the build.

 

It depends on the person being stupid or knowing what they're doing. If the person is smart, their build, tune and part combination and nitrous use will be reflected in it. The stupid people are the ones that always seem to be blowing their motors up and blaming everyone but themselves for it. Then they spread misinformation about why their motors blew up and "what people should do to prevent it from happening to them" and fail to learn from their mistakes.

 

Spoken like a true guru. No arguments on my end.

 

General rule of thumb that i hear is, dont activate it unles WOT and above 3,500 rpm.
