In this episode we select and review the centerpiece for our upgrade plan- the turbocharger! After taking a close look at it, we port and gasket match our exhaust manifold, turbine housing and 02 housing to make the most of our new combo. Thank you for watching and subscribing!

Hallo Tom, I look already some time to buy the set of tools to make the flow in the head of my engine beter but it is verry diffecald. can you atvice me a brand or where to buy it. 😔I want to make a beter flow in my engine.
I used to port, however got sick of the cracks…
Not terribly convinced it does anything either…
Did you really think you could get away with that?
It's a terrible shame to lie to your viewers.
You say your name is "Tom" but your jump suit says "Matt", just be honest, what else have you been lying about?
you make the best videos. good job 🙂
I would say those guys who "overlook" this grinding ports will not end up with cracked parts and leaking seals.
Could do it without all the dumb humor
thanks…. rely cool
That porting looks like shit, like most "do-it-yourself"
the question is could you work in a semi dirty disorganized shop seriously could you …by the way great work i may give them there turbo guys a call for my mk3 supra turbo 6spd 7mgte
this is an awesomee channelllll….. fuck yeahhh tommm
Hello,What do you work with ? To get some money?Very god Jobs att your cars.Andreas from Sweden
your awsome i wish i was your apprentice
you sir have won my like keep up the great videos👌
brave soul with those high speed steel bits on hard iron. Stoked to see non of it cracked using those bits. stone and iron I thought was best of choice for iron work. Didn't see the sanding cones make a dent in the iron in the video. iron way to hard. you end up using stone at the end.
I love all your cars! Especially the dsm and the vr4 . I question why don't you own a 240sx s13 or s14 .. Would be crazy to see what you could do to one of those! Keep up the good work love the work you do on your 4g63's
I enjoyed this video thoroughly
haha i was there that day at norwalk when you played the video of those talons!! sick!
you remind me of them late 90s early 2000s classroom videos we used to watch- nonetheless, i like it… it has car stuffs! lol
You should reconsider using the gasket as the guide to your porting. Often a gasket is intentionally sized so that its inner opening diameter is larger than the mating pieces. This keeps the edge of the gasket away from the roasting hot gases flying by. Exhaust gaskets often have a heat resistant material edged by a soft, white metal. That soft edge isn't nearly as tough as the cast iron and it can be melted. When the joint is tightened it's that metal edge that is compressed and forms the seal. If the inner edge of the seal is burned away the joint is compromised.
Opening the joint to the size of the gasket can also create disruptions to the flow. Picture you have two parts that are already correctly matched and the flow between them is uniform, but the gasket is larger. This creates a very slim, shallow gap between the parts, but it hardly changes flow at all. But grinding the inside diameters of the parts to match the gasket will actually create a disruption in the flow.
I have always used thin cardboard (think cereal box) to perform porting. Make a gasket without the port holes. Then apply water-based paint, machinists blue, graphite… on both surfaces and bolt them together. When you separate the halves, you'll have the perfect shape of both ports on either side of the "gasket". Now cut the ports in the gasket to the size of the largest port. (That could be either side at any point around the port.) Port to match. If you want to open the port up for better flow do that to one side first, then do the cardboard gasket trick to match the other part.
Keep in mind that sometimes a slightly larger header flange is good. Anyone remember anti-reversion headers ?
It's a great video ! I've ported many heads and seen some gains, but I wouldn't have hogged out that wastegate port so much. The wastegate is only flowing when you're overboosting. If the turbo is appropriately sized that shouldn't be so much. The wastegate's flapper valve will only flow so much anyway. Cutting the casting so thin in an area that already highly stressed (glowing !) can only be bad. If the boost gauge doesn't show increasing pressure (higher than the wastegate setting) at higher RPMs you don't have a problem that warrants the increased liability. I'd have just rounded the corners a bit. I don't mean to invalidate the video. It's still a wonderful presentation.
12:00 NINTENDO 64!!! NINTENDO 64!!! 😂😂
Tom where
Did you go to school?
Lovin the power curve for the turbo that didn't even come online until 6 grand
Awesome video! I've never heard of fp, I'll have to look into them!
Very good video,
Loving this build. Sleepers are my favourites and the more they exceed first impressions the better.
