    Now that I understand the science behind everything the only other item that's still up for debate is how it was ported. Some people say its CNC and some people say its Hand Ported.

    do the lines look uniform in the ports? if they say they do cnc... they have photos of heads in cnc machines on their public fb page, so theres that.

    Looks CNC ported from the close up pics you posted. Either that or someone has a really steady hand.

    Okay. So I finally have the full story.

    They CNC Race Port it and then they clean it up by hand. Which is why it has a dull finish instead of a mirror finish. Also did tons of research. Apparently the mirror finish used to help make hp. But now that they have this CNC Race Port down to a science they have realized there are no performance gains anymore from mirror finishes. Once upon a time it made a difference back in the early 90s and later.

    So I was worried for nothing but have learned a lot from this entire experience.

    Thank you everyone for your input and responses.

    The other good news is that my shop is starting the work on the motor tomorrow to get as much done as possibly before the install.

    I am still waiting on my build/spec sheet so I order the proper size headgasket.

    I keep you updated on the progress.

    Update:

    I went by to see my motor and drop off all my supporting mods and ect.

    The pictures DO NOT GIVE ANY JUSTICE to what I saw in person!!!!

    This head is most definitely CNC Race Ported!!! They did a BEAUTIFUL JOB!!!

    The port on the inside of the head was immaculate! I am VERY pleased with the work!!!

    Couple of quick notes. They plugged the oil squirters. They had to in order to get the pistons to clear. Plus I was also told that the oil squirters don't help when you have forged internals. I always thought having oil squirters made a difference. But apparently with my setup oil pressure is more crucial. But I have a Type R oil pump that's CNC Ported and Shimmed according to my build. So I'm probably going to have super high oil pressure lol. But that's not a bad thing.

    I am going to have 1 of the fastest Civics in North Florida. Man I am excited. I don't know anyone with a build similar to mine. And I know a lot of people! But I'm not going to brag too much. Don't want the wrong person finding out what I have.

    This has been an interesting experience and I've learned a lot. I have no idea if I will ever do this again lol. But I did it right the first time and that's what matters.

    The 1 thing that's going to possibly limit the power I make is the Ram Horn A/C Manifold I have. I really should have bought a Top Mount. This motor is going to be extremely efficient and I just don't know if that Ram Horn is going to be able to keep up.

    My HP goal is 900whp. This manifold is probably going to limit me to 700-800whp.

    I am going to probably do a bumper exit exhaust. I don't want hood exit. Unless you guys have some better suggestions on the exhaust.

    I currently have a full true 3 inch exhaust. I was planning on keeping that but I don't know. I'm on the fence about it. But I believe that having the shorter exhaust will open it up more to help it breath a little better, especially since I have that ram horn. I need as much exhaust flow that I can get.

    I should have the build sheet by Monday/Tuesday. Can't wait to see it. I want to see the flow tests/charts for the head and I want to see how much if anything they had to remove from the rods/pistons.

    How many people do you guys know that did not finish their builds and gave up? I'm telling you I came really close to just selling everything because this whole experience was a huge pain in the ass. I just hope all the hard work, patience and money was worth it.

    I am using this fuel pump: 750magnum.

    Its an inline external fuel pump. It supports up to 2000whp. I have FIC 2150's for my injectors. I'm going to be running e85 and COP with OEM Honda K Coils.

    I was told my car will be done within 1-2 weeks.

    I am buying a Gates Racing Kevlar timing belt. And I still need my head gasket. Waiting to order that until I get my Build/Spec Sheet.

    I am so happy. I built it to handle 1500whp. So I have plenty of room to grow if I decide to track it.


    Anyone have any quesses on how much its going to make?

    Good news. I've got the rest of my few parts that I needed. I estimate it will be running by Nov 20th or so. We'll see.

    I'm tuning it for max power. But I'm going to run at 600whp until I learn the car and then I'm going to turn it up. I am super excited. I cannot wait. I've been waiting for this day for a very long time.

    Here's some updates. Pics attached.

    We are getting very close. Doing minor wire tuck on engine harness and fixing some harness issues with damaged wires.

    Going with 3 inch intercooler piping and bigger intercooler.

    Can't wait. So close to the finish line. Closest I've been since really starting the project. About to do fuel upgrades.
