Boosting a B18c???
Ok guys just wanting some advice on the build that i am pursuing. I currently own a 1993 integra RS that weighs 2700lbs with a full tank and me in it. The motor is a GSR with type r pistons and cams. Now i am running a b16 cable trans with a act stage 3 clutch, 4 puck unsprung disc. The suspension is a prototype setup that is fully adjustable coil overs and 8 way dampening(very stiff). I also put in a walbro 255 fuel pump. Also running a skunk 2 pro intake manifold. Now the question is i am wanting to boost this car as is i think the cp ratio is 10.6:1, if i am incorrect someone please correct me. Now what psi could i safely run on a great tune?? I will be running 93 octane. I would like to break into the 11's in the 1/4 if at all POSSIBLE(if not please tell me)...at the track i will be running 15 BFG drag radials...so what kinda hp numbers am i looking at to even think about digging into the 11's... what turbo would be good to run. I also have a set of fic 750's and dsm 450's....which ones will be suitable for what i am going for?? The budget for the setup is mid range, not wanting to go the cheap route but not wanting to go for the most expensive thing out there....any info on this would be great!!! TIA

Re: Boosting a B18c???
you're gonna get flamed asking this question man be careful. Research is your friend! cruise the turbo section. generally with boost the lower the compression the safer it is to run more psi. Its all in the tune. just get a good tune if you dont want to go lower compression.
i have a gsr hatch 9:1 with itr cams, skunk2 IM, running a ramhorn w/ gt30 and i ran a 12.16 on nine pounds. In Montana so thats way worse air here than where you live.
just do some research man

Re: Boosting a B18c???
I would look into different pistons dude
unless you want to boost like 4-6 lbs maybe
even on 93 octane gas
I would go 750's because you can lessen the duty cycle of the injector and the fuel should still atomize fairly well
Your numbers depend on your comp ratio, and has a lot to do with your turbo set up
But the biggest thing will be your driving ability
you might need to go full slicks to reach 11's with not a super built set up

Re: Boosting a B18c???
Pistons and rods are needed to make those times (including your driving skill), as well as about a 53-61 lb/min turbocharger. Building the motor with good engine managment would be needed. Can't do it with the stock motor and still expect to drive home everytime.

Overall your setup and tune will determine your numbers and et's. I have a b18c bottom end i am building for boost. pm me if you have any questions.
