In to the Allmotor scene..! "again" Project b18c build with pictures
Lets see.
Basic info.
-block b18c6 stock 3point girdle
-p73 Crank
-Eagle rods
-Balanced to 0,1g tolerances
-Wiseco pistons (13,2:1)w/stock combustion chamber.
-I will mill down the head estimated 0,060", but I`ll have to meashure when I get the pistons on how much squish and P2V clearence I got.
-Custom spec cams @ 0.050" lift .500" and 263dur intake .500, 272dur exh.
-2layer gasket(we also have to meashure clearences before choosing 2-3layer.
-TWM itb
-ACL bearings
-B16 head
-P72 LMA
-Moroso pan
-Omni valvtrain Flatface valves
EMS
Hondata s300 running off Alpha-N TPS signal.
Tri Y header
2,5" custom exhaust
I also want to thank Scott at king motorsports for the nice service they provide..!!
I`ll post pics of the engine (empty of internals first so you get an idea of what it looks like)

Around 230whp are estimated.
My goal are to get as much average hp as possible rather than peak power on this one.

Head waiting for valves. and milling. as said above, if the valvepockets P2V clearences and the squish P2H clearences allow I will mill down about 0.060" to accieve the compression ratio that we want.
The engine is beeing built for E85


I use a contricity gauge to meashure the valveseat runout to make shure the seats are concentric after all angles/radiuses are aplied if not the seats must be replaced.





Also note the unfinished area around the valveguide, some parts of the port beside this spot, must never be removed, also some other areas
As for this the Combustionchamber is Worked out a bit to help maintain mixture homogeneity, flow, and combustion travel as well as increasing flow at high lifts by descruding valves, even though the almost stock bore is limiting the amount beeing taken.
It may look very shiny (polished) but the finish is nowere near polished.
280grit is beeing used to smooth it.
The Intake channel is smoothed with a 120grit emery paper and the exhaust runner are smoothed with 280grit emery.
Also the divider are rounded(at a point in the port work it got knife edged and I dont want that)
here is a funny calculation just to see how fast the intake valve opens per second when engine have about 10000 rev pr minute.
here it goes.
<U>10000</U>/60 =83,34 O pr second

That clears up why you want a rough finish on you intake runners.
The engines are based of a non-direct (I dont know the english word) Injection leaving the atomized fuel on the intake walls and on the back of the valve.
most of it ends up on the walls and around the valve area, until the valve finally opens and draws in the air fuel mixture. Keeping the walls rough helps break up the fuel particles before entering the swirl chamber.
The better you can mix the charge with air the more efficient you can use energy suplied.

instead of just posting pictures, maybe you could explain the process that you are going through and what these pictures are supposed to represent.
cool build and all, but no one is really learning anything and after all, that is what this forum is for.

It is a EK chassie.
I will post up pictures of it. just need to go through 2000pics first..

Found them.
Here is the car that the engine is going in to.
It did 223.7 whp at 14,7psi on a stock 1,5 vtec(d15z6)
Now I found it was time to build it a little diffrent before we sell it.

sorry for the ignorant question but i don't have much experience with itbs.........that black thing around the "trumpets" does what exactly??? is there a filter that goes on top of that??? or like a resonator box or something??? What is it? Thanks in advance.

Hi, It is the underside of a carbon plenum

Last pics before the parts are here.
I`ll have some more pics up.
this time Im meashuring the chamber volume, after this I will be meashuring the cyl/piston volume to know the total volume and C/R
The meashuring will be done again with the new valves in later to get the exact volume. syl 4 had 2cc less than the three other sylinders so I had to even that out.
Here is some pictures:

I picked up some parts at the local postoffice today..
only waiting for some lightweight rods now so I can start to assembe, the eagles were sold to someone that needed it more than me..

You allready know the details.
