b16a + mild boost?

I was looking into possible mods, someone can easily drop $1000 into small engine mods, and not really get much for it,

well how about some boost on a b16a? how much can a stock engine take without any heavy wear on it, 4lbs? etc? what kind of power would that yield even and more so how much would it cost for a small turbo setup, not for crazy power, just for more fun when driving =)

and then what would be ideal, SC or turbo? if going for low boost 4-6lbs, what would need to be changed? injectors / ecu etc?

you'll need to treat running even 4psi as if you were running 15psi. You NEED bigger injectors, high volume fuel pump, fully tuned ecu.
Don't s/c a b16, turbo for sure.
I'm running 4-5 psi on my high compression (11.5:1) b16 and she boogies. I'll be running more (whatever it takes to hit 300whp) after i get it to the dyno.
Stock b16s can handle 300whp IMO so whatever psi it takes to get there is whats safe to run, depending on the turbo it could be 10psi or 15psi. You will get very bored of 4 psi really fast. So when you get your car tuned, have it tuned for the MAX psi you'll be running, that way, when you get bored of your current boost level, you won't have to go back and pay for tuning again for higher PSI.
B16s take boost very well, and make very nice power when properly tuned.....vtec + boost = constant smile on your face.

damn 11.5:1 + boost :P ur nuts, no problems running this? on street gas?

how about cost? I see alot of people using H22 injectors, I really don't want to blow my load on gas, which is the problem for now, I'll either be doing this in the fall or next year summer, but I'm going to start picking up parts soon =)

Run at least 450cc injectors and keep in mind that you should run 94 octane on a boosted motor so if you can't afford that then re-examine your options. Gas isn't gonna get any cheaper ya know. Gotta pay to play.

don't waste your time with h22 (345cc) injectors. You want at least 440cc injectors to be safe and to leave room for higher boost levels without maxing them out.

I'm running 94 octance (as anyone that boosts should) pump gas. The car made 167.7whp n/a and my buddy gave me his turbo kit, so i couldn't refuse.

well did you say you got BETTER gas milage after the boost =p? currently on a stock b16a I get 520km/tank roughly about 11.8km / l

I don't mind paying for 94, I already pay for 91 so it's not much of a difference, jus twondering how much more it will eat =p

well, out of boost, i get better gas mileage, but when boostin around, with such rich air/fuel ratios (which are required to be safe) it will use more gas than before.

Things IMO that you can do to save $ on a low budget kit
ebay for piping,BOV,Intercooler,Exhaust,&cast mani. I used the meu*** mani last year (there only like $100) and it was excellent no boost creep/spike nice gate placement. made 300 @11lbs with a stock ls
Just spend the $ on a decent wastegate, turbo, and fuel system (or pick up good quality used parts)
But the first thing u have to do is set 2 goals HP and $.

honestly I don't know what to expect, I mean I'd probably be happy @ 180-200whp is that too much of an expectation with low boost on a stock motor otherwise?

if anyone has any experience with a stock b16a + boost and has numbers what can be expected from 4-6psi, or 8 or 10psi?

My goal is in all honesty to make this car more fun, and take it out to the track days(not drag strip) for some more fun, Eventually I'll buy a bigger automatic car(fiance :<) and keep this as my hobby car

budget on the turbo setup I was lookin to spend about $3000, so is 200whp doable safely with boost for within that budget? or am i dreaming here?

man, you'll far surpass 200whp with $3000 to spend on a turbo setup. Search up on honda-tech for dyno charts of boosted b16s, you should be in the 250whp no problem at 8-10psi.

I'm anxious to see them

btw, how about upgrading the oil pump, not neccessary for this much power?

well, if its old and you are worried about it, get a new one, preferrably 98+.
But would i change the oil pump to make 300whp?...no. Hell i've never really used anything other than stock oil pumps before and they always hold up, well, b-series that is.
