I am rebuilding my motor and I am going to buy some forged pistons for B18c1. My plans are to build it all motor but I am also planing on spraying at the most 100 shot. Anybody have a set-up like this that works well, should give me a litlle advice on pistons(CR) and rods. I would like to make 200 N/A and 270ish on spray to the wheels. I also did search and came up with nothing. I also know its going to take more than just pistons and rods to get 200 all motor. Thanks
P.S. happy holidays!!

 

go with some je 11.1 or so and some eagle rods. or if u want to stay with honda parts u could get ctr (pct) pistons. they also bump compression up. also a single or 2 layer headgasket will bump the compression a little. i wouldn't get too big of cams with a 100 shot of nitrous. just my .02

 

when i planned on spraying i was using some cp 11-1 pistons on eagle rods with s2s1 cams. i never sprayed though so sorry i cant help you on that part but with higher comp be sure to have a good tune on it. what kind of engine management,injectors and fp are you going to use? it would be sad to run lean and blow your motor. later and good luck jason

 

Thanks guys anyone else ??

 

When I built my all motor/nitrous motor, I went with Arias 10.4:1 pistons (+ head milled .20 to make it like 10.8... i forget) - used crower head components (stage 2) and used a hondata s200 to control the nitrous and to tune the car. It ran great... i sprayed a 125 shot on 94 octane gas --- also, i used eagle rods (stock LS crank and eagle LS rods in a b18c1 longblock). I used RC 310 injectors ... 310-370cc injectors work great... you should make between 185-205 NA and like 270 w/ a 100 shot. -- I'd also recommend some kind of multi-spark ignition (ie: MSD 6AL) - Overall this is a pretty nice, and somewhat inexpensive setup. Lots of fun for a daily driver --- Let me know if you have any questions.

 

thanks for the suggestions. I was thinking of doing arias or cp somewhere around 10.8-11.0 cr piston. with RM or Omni valvetrain (flat faced valves) I am yet to decide on a set of cams, but was thinking buddy club 3 or 3++ maybe crowers or s2s2. I was also toying with the idea of a b20 crank and rods (I have one lying around with a set of eagle rods too) I also have a AEM ems to controll everything. What style nitrous shot did you use? Also what brand?
Thanks for the great reply.
Just wanted to get more ideas from someone who has run a similar setup before I assemble mine.

 

Making 270whp on a 100 shot is easy to do. I would run somewhere around 10.5-11.1 forged pistons with a set of mild cams. I had a type-r with 10.5cr slugs with or a 75 shot and it went 11.83 @ 115 in a daily driven 2350 pound hatch on pump gas.

 

my brother ran a 11.8:1 comp h22a motor in his hatch with a 75 shot, with a leaking nitrous line...he ran a 12.1@115, spinning out all the way down the track...all you will need is something to tune it, and looks like you have an aem ems already, so you'll be fine.

 

my brothers name on here is .derf.

he has a nos set up

b18a block std bore
gsr crank and rods
je 12.5 to 1 comp pistons
eagle plus size rods
block guard

ported b16 head
buddy club bc4 cams
toda header
ported type r intake manifold
65mm throttle body
rc 310 injectors

car makes over 215whp all motor and is spraying a 150 shot
car has been running with this set up for about 1 1/2 years and is beat on a lot.
car has gone 12.49@108 all motor and 11.29@125 on spray

hope this can help a little

 

 

Thanks guys. I see you guys are running higher compression than what I was thinking but I might do 11.5 or so. Thanks for the responses. Also does anyone know how much a stock rod weighs vs a eagle?
Also did you guys have any head work done? And if so who?
