    The exhaust is stock right now aside from the stainless group m replica muffler.

    I will be installing the RMS headers with 1 3/4" primaries to a custom dual 2.5" exhaust. Should flow pretty nice. Click here to enlarge

    Here's a little update for you guys.

    I received the new crankshaft. I ended up purchasing an s54 crank because I could not source a euro crank and I didn't want to wait. Click here to enlarge

    The pistons we ordered were 8.5:1 and I wanted 9.5:1 in order the keep some of the low end power. I hear from a lot of people that the lower compression really flattens out the power band down low. I'd like to stay away from that. The wrong pistons will be kept for another project down the line. The 9.5:1 pistons are about 4 weeks away. I'll be placing the order for the rods tomorrow. Next week I will purchase all the necessary gaskets for an engine rebuild.

    In the mean time, I have been working on the hats and brackets for the big brake kit. I'm using wilwood W6a calipers up front and W4a calipers in back. Let me know if you guys want more details on the brakes.

    Here's some pictures!

    ^ Thanks for the update, nice.

    Why not go 8.5:1 and run a ton more boost? Would the low end of 8.5 vs. 9.5 really be that noticeable once supercharged anyway?

    I want to run the 8.5:1 compression. I just keep hearing that the lower compression kills low end torque. I might still use the 8.5:1 and just run more boost. I too have a feeling the loss will not be that noticeable. We will see. Either way, the 9.5:1 pistons are being made right now and are about 4 weeks away.

    There is a pretty substantial difference in power going from 8.5 to 9.5. Centrifugals arent known for their low end torque, hence a good plan is to stick with the 9.5 to make up for that.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    Huh? I thought your motor was stock?

    Yes but what if all you want is top end power?

    You buy a giant turbo. Click here to enlarge

    9.5 will have a bit better response, be able to make the same power at less psi, but he may not get as far on pump gas.

    Will this thing be on race gas maxed out all the time? Just make sure to size the blower properly for what you want, I'm sure that has already been taken into consideration though.

    8.5 would most likely allow him to run more boost on pump but without the low end response.

    8.5 is way too low of a CR imo for this car, especially for a supercharger. Personally I think anywhere from 9.0-10.0 is perfect for a supercharger, the lower of the range only if you are planning a huge build with something bigger than a T-Trim and lots of fueling upgrades.

    Here's an update for you guys.

    Pistons FINALLY arrived from arias.

    Specs:
    Compression Ratio 9.0:1
    Weight 353g
    Ceramic Coated tops
    Moly Coated Skirts

    These are some quality pistons. It was deffinitely worth the wait. I'm still waiting to order the rods. I need to save up a little more cash. This project is moving slowly due to cash flow issues on my end, but when it is finished, it will be one hell of a car. Click here to enlarge

    Enjoy!

    Holy $#@! those are sexy looking! Love the coating! Anything to help with cylinder temps helps. Glad to see you taking your time to build this beast. 9:1 is a good ratio.

    Can't wait to see it finished!

    Thanks man!

    I'm in a chemistry class right now and I am learning about ceramic coatings. The science behind it is amazing.

    9:1... nice! Big power is in store.

    Not really all too familiar with the piston coating. So it is to keep the temps down? Looks great.

    From what I have been learning in school, the ceramic coating helps with the heat. Ceramic materials have a high specific heat capacity.

    heat capacity defined:
    The quantity of heat energy required to change the temperature of a given amount of a substance by 1 C.

    Little bit of schooling for those of you that don't know about heat capacity, as I didn't a few weeks ago.

    Ok, we finished fitting the headers and they're off to be finalized. We pulled the motor and we have began disassembly. Hoping to have the engine fully disassembled by tonight. Click here to enlarge

    Here are some pictures of the motor coming out.
