Boosting a b18c1
Im doing some research to boost a b18c1, my goals and expectations on this build are simple. My goal is to achieve in the range of 240~250whp on a stock block/internals, compression, valve train, ect...
1. Im sure that 240whp is achievable on a stock block (duh!
), but what about reliability besides tuning, I am aware that a good tune is a must for reliability. My expectations aren't very high, so if boosting to gain up to 240whp isn't such a smart idea then what could I safely achieve by boosting a stock block? I do plan on getting some bigger injectors.
2. I know that how much psi I can boost to and size of the turbo it's self is a factor here, but like I said my expectations aren't very high. So, Im definitely not looking to get some gianormous turbo obviously, in-fact the opposite. Im looking to get the smallest turbo possible that still makes decent power up to 8000rpm's
Here's some info on the car/engine if it matters.
stock 1997 Integra with 125k miles, stock b18c1, stock tranny
I have done a compression test on the engine and all cylinders check out ok at approximately 240psi give or take 2~3 psi, although the car(engine) does tend to burn some oil when in v-tec. I have owned the car for the past 4 years, I don't abuse it but I definitely don't baby it either, I use nothing but 93 octane, and 20w-50 full syn oil with 5k miles between oil changes.
I am doing research elsewhere to be abel to answer those questions myself, but any info I can get from you guys here would be greatly appreciated. Thanks.

Re: Boosting a b18c1 (The un-chossen one)
300whp would be easy with the stock gsr. just get a good fuel pump. and id go with some 550 cc injectors. and your gonna want a good clutch too. that thing will slip in highway gears. also find a very good tuner and your car could be very reliable. if you only wanted 250 whp then you would have no prob driving the car boosted for a long time...id also get a cast style manifold for quick spool. and a 50 or 543 trim turbo. wopuld work nicley to 8,000 rmp. dont get a cheap waste gate since you dont want to spike your boost on stock internals.... there is a start. more people will add comments... HAVE FUN!

You'll be fine boosting a stock block, As you said before, a Tune is a must. You'll probably make more then your goal of 240-250hp depending on how much you want to spend and what turbo setup your wanting to go with. An Sc61 would get you into the 300's, if you really want to go small you could always go with a T28...but I'm sure you'll want to go bigger in the near future.

the 240-250 hp range is easily obtainable and safe.
a good turbo size would prob be a .48 hot and a .60 cold
240 psi is kinda high for a stock b18C1
all mine have burnt a little oil when raggin on it, less on the new motor though
run 10W30 istead of 20w50, its not hot enought to run that thick of oil
definately change your oil way sooner than 5000 especially boosted

Re: (FastEg6)
Like everyone stated, it's all in the tune. Another note is to make sure maintenance is TOP PRIORITY!! My stock b18c + t3/t4 57trim lasted 3yrs, if not for my mistake of retuning for max power she'd still be alive today. She was VERY RELIABLE with 25-28mpg city driving and 30-32mpg highway. 
Also, don't go cheap with your build. Do it right the first time and buy quality parts!!

I was going to say the same thing, but you beat me to it. My suggestion is something in the range of a 57 trim. I used a GT3255b (journal bearing) and made 315/216 on my stock block GSR on 91 octane. Combined with my SLS shorty, it made full boost by 3800rpm on the street. If you want more info about it, PM TheShodan

Re: (Schister66)
I just find it foolish to use a massively large turbo for the sake of saying you have "xx turbo", when you run 7psi on it because your motor can't handle what is the sweet spot of the turbo in terms of boost pressure and power.
This is why I can't figure out why a lot of honda guys run massive t3/t4's and only make 300-320whp. Seems foolish to me, or there's a lot of efficiency lost somewhere.
My goal is probably 420-450whp with 9.5:1 pistons and crower rods on stock sleeves in my b18c1 when all is said and done. And I'll use a turbo that will max out at probably 500whp, just so I'm not on the ragged edge of the turbo, but not using one too big and therefore unenecessarily laggy.

Someone finally gets it
Read this post and take it to heart. There's no reason to run an overly large turbo at 7psi when you could run something smaller in its efficiency range and make the same power, but with more boost AND have a ton better powerband.
This is the reason i get pissed when people buy a GT30r or GT35r and want 300-350whp. It just makes no sense to me... You may as well get a BW S372 and run 4psi on a stock D series

I just happen to have an SLS shorty I may be upgrading from in the very near future.... but it has a 44m WG flange
