Need direction from HT gods
Although this may seem like an odd post, i know all great honda builders have undergone ( in some form or another ) a builder's block, similair to a writers block. I have been building a my babay for a long time. When i say building that includes time that i have had to save up for the build, but anyway I guess i will start with what i have and then ask for inputs on direction. I have a grab bag full of gsr parts( harness, water pump, engine mounts, everything that came on the original)
My Built block:
86mm Endyn Rolloerwave pistons
GE connectung rods
stock gsr crank
gorilla sleeves
My head:
Full port done, and combustion chamber bore to match block by CNC motorsports
Manley valve springs and titanium retainers
brass valve guides
ferrea valves
I am still trying to decide on cams i can go up to 510 lift and i would like some suggestions on cams for a good street/strip setup
and furthermore once i deciede on a solid set of cams that will make good power up top, but wont leave me lacking down low, i need to decide on how much i need to get milled off the head.
Other:
Circuitworx oil pump gear
My Goal:
a mid 200's all motor
displacement >2.0 litres
What i need help on:
-Deciding what size injectors to purcahase
-Deciding on what cams to get
-deciding on whether to go s200 or s300
-basically the raod block i am encountering on my first "real" build is the order in which i need to select my components, like injectors before cams.... so on and so forth, and a little inspiration, any help would be greatly appreciated.
Will Post pics of block, parts and whatever else i forgot next.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by eghatchback.com »</TD></TR><TR><TD CLASS="quote">Basically, you can figure out your best choice for injector sizing if you just know a couple things about B.S.F.C.
BSFC = Brake Specific Fuel Consumption
Basically How much fuel your using per horsepower per hour.
Here you go.
n most cases a naturally aspirated engine will have a B.S.F.C of .50. This means that the engine will use .50 lbs. of fuel per hour for each horsepower it produces. Turbocharged engines will want to be at .60 lbs. per hour or higher.
Using these numbers as a guideline, you can select the approximate injector size in the following formula for a four cylinder, naturally aspirated engine at 200 bhp.
Most injectors will max out at 80% duty cycle and this is the accepted industry standard.
Now, to get what you want you have to have a round-a-bout way of guessing how much horsepower you want to make. And insert it into the little mathmatical equasion I put here.
You use this one to find out how big of an injector you need to use if your shooting for a certain horsepower.
This one you are going to use if you want to see how much horsepower an injector will roughly accomodate!
If you don't understand this, please post your questions. I'll answer them to the best of my knownledge.</TD></TR></TABLE>
