Cutting Excess Guide from ProComp 210 SBC Head, custom Porting Combustion Chambers 4
Part Four of Port modificatins on ProComp 210cc aluminum SBC heads. Guide over hang from installation and correcting the combustion chambers to unshroud the spark plug is a big deal on these heads. China castings leave a lot to be desired, but still with all the work you must do it is still the bargin of the year and is a force to be reckond with when "bang per buck" is needed. The base of the spark plug should not be exposed in the chamber, and any valve guide "Overhang" will obstruck flow and create fuel "sheer" which seperates vapor to droplets that wont burn. Most Big Name companies will not take time to detial these issues as production cost prohibit these mods, so have your local machine shop take apart your heads and look for these problems before you bolt them on your prize engine. www.headbytes.com 615-212-7168

Volvo Engine head porting/ matching exhaust
Gasket matching my Exhaust port on the head. Nothing spectacular and quite boring to watch but quite tricky to do. The point on this "process" is to align correctly the Exhaust port with the Exhaust manifold to allow gas to flow without turbulence. it can exit faster and let more fresh air come inside the cylinder. In the same time the shape of this port is important : the very light conical shape is a good and reliable design for Exhaust. the point is to grind very far to have a tight curve and not only grind to match.

greddy knockoff intake manifold for sr20det s13
I recently purchased a greddy knock off intake manifold off ebay and wanted to see what the quality was. It was ok but a couple issues are the factory fuel rail bolt hole do not line up perfectly and the electroplated chrome is easy to flake off. I am unsure if i will install in onto my motor. leave a comment if you have installed it on your car and if you liked it. I would encourage any feedback on this with the knockoff and the genuine part. thanks for watching





DIY: Porting & Polishing a Throttle Body
Video tutorial on how to port and polish a vehicle's throttle body. In order to do this procedure, you must remove the throttle body from the engine so you can probably polish and port the throttle body and the material shavings do not enter the engine. This isn't much of a horsepower increase if any, but it does help with throttle response. Do not remove any material from around where the throttle plate touches in the bore either. Also when doing this procedure, I would recommend purchasing a new throttle body gasket so you won't have any vacuum leaks once reinstalling. Make sure you don't take off too much material either where it will affect the structural integrity of the throttle body. When doing this type of work, make sure you wear safety glasses for your own person protection. Procedure: -remove the throttle body from the vehicle -clean any oily build-up inside of the throttle body -remove the butterfly from the throttle body, most are held in with 2 screws that go into the shaft -if you can, also remove the shaft and linkage (some shafts are pressed into bearings, other are not) -if you can't remove the shaft, no big deal you just have to work around it -tape around the shaft or the hole where the shaft was so no metal shavings get into that area and cause premature wear for the bushings or bearings -depending on the finish of the throttle body's bore, there may be edges which you can to smooth out -in order to smooth out those edges, you can use grinding stones for either a drill or rotary tool such as a Dremel -when using a grinding stone, it's best to use WD-40 penetrating oil with it so the aluminum material doesn't plug up the stone and it'll no longer cut away any material -once you are satisfied with the sharper edges being ground down, you can down move onto sanding drums for the rotary tool -you can also flare out the bore where the air enters slightly so it has a smoother air flow into the throttle body -you can even port match the throttle body to the intake if the throttle body is smaller -if you don't have access to a rotary tool and sanding drums, you can also use flap wheel drum sanders that can be used on a drill -the flap wheel drum sanders are available in a variety of grits such as 40, 50, 60, 80, 120, 180, 240, and 320 -when using the flap wheel drum sander, you can add water to help with finer sanding as to keep the dust down -if the surface isn't too porous such as what is shown in the video, start out with a finer grit like 120 and move your way up -once you have reached the highest grit in a flap wheel drum sander, you can now do some sanding by hand with 400 grit and add some water for lubrication -once satisfied with your product, you can now move up to an abrasive like Scotch Brite -depending on the color, will depending on how course the abrasive pad material is -I started out with green and then moved onto the red pad for the finest compound -you can also use water with this too to help finer sanding and to keep the dust down -again once you are satisfied, you can now move onto a metal polishing compound -the metal polishing compound I would recommend is Eagle One -apply the polishing compound paste and rub until highly mirrored finish (multiple coats can be applied to achieve a higher polished surface -once you are done with the bore, you can now move onto the throttle plate -most throttle plates are smooth to begin with so you can skip directly to the Scotch Brite stage using the same procedure and finally move onto the metal polishing compound -once done, you are ready to reassemble the throttle body -make sure you peen the thread of the screws on the other side to ensure they don't come out or apply Lock Tight thread sealant -install new throttle body gasket along with throttle body to your vehicle Thank you to all those who watch my videos and support my content.

What i use to polish cylinder heads and intake manifolds
Join me on Facebook! www.facebook.com/omgitsmrmack Just showing your guys how we go about polishing and getting the beautiful finishes after its all said and done.. this method takes some skill.. some might say i make it look easy.. at 14000rpm the grinder i use is not a joke and has hurt people when they dont use it properly.. when the paper unloads on a long rod it tends to bend the rod at a 90 degree angle and if the user freaks out and does not hold it away and let it slow down then they end up with a nice big sliced up arm or mid section.. i myself have bent a few in my time and lucky for my i have a quick reflex and manage to hold it away without hurting myself..





Throttle Body Port and Polish on a 2006 Chrysler 300
Throttle Body Port and Polish on a 2006 Chrysler 300. Turned out well, it was my first one ever done so it should go way easier next time. Car drove perfect, no issues at all. I didn't notice a horsepower Boost but the throttle response is quicker for sure.





UPDATE!! 1997 nissan s14 kouki sr20det build (part2) with dyno video!
*skip to 18:18 to see video of the car running *skip to 24:53 for Dyno video so after my last video the car ran good for about 2 weeks. long story short, the tune that my last shop did set my motor up for detonation so cylinder #1 dropped a significant amount of compression. the other 3 did as well but not to such a degree. it took me around 7-8 months to gather enough money to go with forged internals rather than OEM. i was on the verge of purchasing all the parts when i came across what i thought was too good to be true. someone in north carolina had a nice 1996 nissan 240se shell and fully built block for sale. he was asking right around what it would of cost me to rebuild my motor and considering i was getting a entire car and many aftermarket parts with it, it was a no-brainer for me... I WAS SOLD! here are SOME of the parts included with the 1996 240 shell: -Freddy intake manifold/$140 FULLY ASSEMBLED BLOCK (BLUEPRINTED AND RACE BALANCED) -9:1 forged cp pistons $470 -Brian crower 1200hp "I beam extreme" 19mm GT-R +625 ARP hardware/ $630 -ACL race rod and main bearings /$121.60 -nissan thrust washer /$12 -B&M short shifter/$200 -magan manifold/$101 -Megan turbo elbow/$55 -stock inj w/ fuel rail/$80 -Intercooler and piping/$140 -t25 stock turbo/$100 -sr20 stock maf/$45 -sr20det stock oil pan/$30 -winning specialties harness/$200 -sr20det transmission -stance rear upper control arms -stance coilovers/ $1000 -greddy blow off valve -turbosmart Boost controller -z32 MAF and some other stuff.. picked it all up and the rest was history. car made some healthy numbers after everything was dialed in, the head will get built next and them I'm gonna be going for 450hp so subscribe for updates hope you enjoyed and thanks for watching Dyno tuned by rolo at CFT turbo in orlando
