@@jimhiscott2918 your going to need a leaf blower turbo if your running 90 pounds, conventional turbos would not cope with that strain, be sure you use extra virgin olive oil to many impurities in vegetable oil, slap on a toilet roll dump pipe and she will roar mate

use fiberglass in that mache too

I hope this becomes more readily available for old engines that have great aftermarket support for rebuild kits. You can keep an old car running indefinitely if you can keep buying all the pieces, block included! :3

For sure!

Umm no

What percentage of blocks on the road are stock? At least 99%

cast engines have machined surfaces where necessary so there's really no difference. billet just cost more

Counterpoint: The billet block costs more than the rest of the fucking car and the cast iron block will be fine for 99.995% of hotrodders out there. Spend your money wisely. If you're on KZfaq looking up whether you need a billet block or not YOU DON'T NEED A BILLET BLOCK!

There are run a popper valved loop charged 2 stroke but you can cut ports into them also as aluminum is much easier to machine and weld up water jacket for port cutting. this is a chevy sb cast 2 stroke conversion:www.4btswaps.com/threads/turning-4stroke-into-2-stroke.12888/#lg=thread-12888&slide=0. Are these billet engines running stock oil injection system? They could with a dry sump, vro pump feeding into intake and amsoil dominator 2 stroke synth oil. I can wait to try this but a 1:1 crank speed came is needed to work int/exh valves with exh opening earlier for blow down. Its nice to see these billet 2 strokes run awsome!

@@drumbum7999 well yeah, but they are used in more high powered things, since they are lighter (not by too much) and they can resist deformation since they have a higher elongation and elastic ratio, compared to cast iron, to where if you try to bend, it'll snap before you were able to bend it. Thats what they were saying about the 2% for cast iron and the 10% for the forged aluminum alloy block. Remember, its mostly used by professionals who win lots of money, so its not really practical for a daily driver, unless its something you want to pass down to your 3 generation of grand kids. Be in mind, i don't know if it'll last that long myself, due to wear and tear, it might though, if it had constant servicing to it to keep it well maintained

10k for a billet 2jz is actually a pretty good price

$10k for the block, so probably only $6k more than a normal build.

@@StreetFXofficial that's actually not that bad.

I'm unsure if the 10k includes the cradle, sleeves and so forth, or just the bare block. That would be a question for Bullet.

@@StreetFXofficial do you think 9mm bullet is reliable

Yeah to be honest, when you're making 2,000 hp I'll tell you tight now $10k is a drop in the bucket on your car.

Titanium alloy would be awesome

@Mickey Mishra - 2020 was looking to be a great year? BOY did you get that wrong!

Well then

Thats some zoophilic shit right there

SeaN Black why would you think of a boxer breed weirdo lol

@@jadenwracing8176 ok chill kid

exactly what i was thinking, what they said was pretty optimistic, might work well anyway for a while though

seemed like they had a big safety coefficient though, they design was much less conservative

it's 6061 t6 aluminium...used in billet builds. the same aluminium used in coca cola cans or beer cans. and trust me It's pretty strong.

From looking at the model they showed, there are a series of rectangular carvings toward the top of the block running along each side, with bolt holes and what looks like a sealing surface. I think that is the "water jacket." Even though it is not as close to the cylinder as on the original, it should be fine due to the higher heat conductivity of aluminum.

True. But, then again, not too many people run 300 degree thermostats.

So billet can’t be used for daily or normal car guy??

Thanks for correcting my memory - I had the impression those engines were sleeveless.

@@podamis314 They came factory sleeveless, then, when they messed up, we bored em out for steel sleeves.😏

Thank you 🤗

the 2JZ is good, but definitely overrated. I suspect if all vehicles had the same aftermarket, there would be a few better options, and several surprises.

You can hear the RB head engine sound amazing even as a stroker and in NA applications vs 2JZ even 1jz. The RB sound is unmistakable. While with the JZ the Toyota block casting is the key while the rb25/26 are even weaker than Aussie cast Rb30 - something was definitely wrong with Nissan Japan for the rb25/26 block casting. They went from one of the strongest L6 blocks in the L series to the crack prone RB casting. Many Japanese are using the L series with RB heads for budget/strength in drag racing.

Just like the old line about there's no seed substitute for cubic inches should really be no substitute for cubic money

mpetersen6 got that right, no replacement for displacement 👍

Cylinder walls are subject to a completely different form of stress.

alu remove all the heat faster and weight less, so in turn you can pump more power into the engine

chad danylak C’mon dude, engine block weight has nothing to do with the amount of power it can make. That only counts for moving parts, not the block. Jesus Christ....

@@StreetFXofficial an obvious downside to aluminum is that it will destroy itself if your cooling is inadequate for a couple minutes. Oh, your engine overheated? Rip it out, replace gaskets and level the surface. Ask anyone with a Subaru or Toyota.

@@StreetFXofficial most engines cast or not have sleeves....

.

There is no need to use forged iron. It has enough strength in cast form. Aluminum is much much weaker and only in applications of insane horsepower and you having the money to you use forged. A cast iron block is still much much stronger than forged Aluminum. I have never seen so many dumb comments. Even the guy in the video didn't know all Aluminum motors used sleeves.

@@johntate4638 oh yeah you know better than a man who does this stuff for a living and has a big ass company

You will have fun machining this type of steel xD

CPM 10V lol

Only drag blocks have no coolant passages because they are not running for long periods.

@@StreetFXofficial I think we all know that part, just like in the old SBC days hardcore drag racers would completely fill their blocks with concrete, while the guys who stayed on the street would only half fill them. It just got me wondering because from the video, it didn't really look like any of the blocks had coolant passages, or if they did, they only went about 1.5" (40mm) into the block. I would have believed you if you said a street motor only needs coolant in the heads with the conductivity of aluminum and cooling properties of oil, especially with a cooler installed. My 2015 Tacoma is the first vehicle I've owned with aluminum heads and block and I have noticed that it dissipates heat a lot quicker in the winter. With my old 5.0 Mustang (iron block and heads) would still be warm after sitting shut off in 30*F for a few hours. My Tacoma on the other hand, even just after 1.5 hours, it takes a couple minutes of driving to get the needle off the seat of the gauge. There's a lot of variables with it though, the Tacoma is higher up with a much roomier engine bay, all though it's pretty much boxed in with the skid plates. The Mustang was lower and fit and a tighter, but it was completely open underneath, with an oversized radiator that holds more coolant. I like wondering about things though. I often wonder if a straight 6 really needs counterweights on the crank at all, when built right. Or if sidedraft Webers can be jetted and reworked to distribute meth injection systems and ran as an ITB/fuel injection set up.

What's so wrong with the path?

@@Kekkojoker90 Probably could be optimized further regarding time consumption.

i mean it gets the job done doesnt it

When it takes a whole day to machine a block, I think the small savings woukd be negligible in the scheme of things.

@@StreetFXofficial Yeah after the first guy replied to me I realized I over reacted. They aren't a production shop having to pop out 10,000 of these a month.

I know its been 3 years lol but what do you have? Did you see that 4g63? Thats insane lol

My Name did you not listen to the guy? He said they were great until 1500hp After that they needed to thicken the cylinder walls and the bell housing, and the aluminum has the same strength with better elasticity

@@robertmcquarrie452 no I didnt i was at work and it's super loud lol guess it would've helped to hear it too.

they show it in video they have a cover plate that bolts on over the water galleries

How is the engine cooled if there is no water jacket

@@nats2956I assume that since a drag race is at most around 2 minutes run time including burnouts, the engine doesn’t stay running long enough for not having a water jacket to be a big problem

mrnicktoyou both engine are strong with cast block but it only can handle 1300hp till they crack while these billet can handle 2200hp with bigger psi with no crack
