What is a BILLET ENGINE, and when should you get one? vs cast 2JZ: Bullet Race Engineering Tour.

Following on from our "Frankenstein 2J RB" a few weeks ago, we flew to Adelaide to speak to Darren from Bullet Race Engineering about what makes a billet engine better, and at what point you might consider one over a standard cast iron block.
While we were there we got a factory tour and watched some billet 4G63's being milled up.
Huge thanks to Bullet for taking the time to show us around!

I'm going to build a paper mache Honda B16 block and sleeve it with ceramic coffee cups. Top it off with 90 pounds of boost👍 Believe it or not when my son was racing MX at age 15 we would do this very thing. We would talk about how we would build a fully boosted motor in arts class. We would laugh for hours thinking up really funny stuff. On a very sad note he is now in Arizona at age 35 and on drugs really bad. I have not heard from him in a year! But don't stop with the arts class engine build ideas my friends. It brings back good memories ❤

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!

[@ODST_Republic]

@@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

"Billet" is usually taken as being an aluminium based alloy, but it can be any metal, which brings up the question - has anyone machined the block and/or head out of steel? While it would be heavier overall, part of that might be mitigated by less material being required, and it would definitely offer stiffness and thermal expansion benefits over aluminium. The only example that comes to mind where it was done was back in the day when someone (reportedly) machined a steel BD series block up because he was tired of blocks failing.

[@borutgoli840]

It all depends what you need and what you are willing to spend. Billet is for small quantity, custom fast made process. You draw your head, cam, crank in a CAD program and after a day or two you have your product. With a cast you need a whole factory process and it can't just be made when you need it. Casting is for large quantity needs. About strength yes billet is stronger and suitable for performance engines. Cast is more suitable for daily driver needs. Also with forging or billeting you have different expansion properties of the material. This is ok with sport usage since engine dont operate cold and is usualy heated by pooring hot oil like in F1 sport. With cars having forged or billet parts you are just looking for increased wear in cold start since forged pistons for instance have to have bigger clearence and thus rattle inside the cylinder until operating temp is achived.

I wish I could have seen how they milled water jackets in the billet piece. Also, on the comment that the aluminum has the same tensile strength as cast. This may be true at room temp. Aluminum loses over 1/3 of it's modulus of elasticity when raised past 300 degrees F. It keeps getting worse as you go up.

[@austinnafziger4159]

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.

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.

This raises more questions than it answers. Does the oiling system keep the block cool enough to not need coolant passages? What kind of things make assembly different than a factory block, just the headstuds and possibly torque specs? What makes the RB heads flow better than a JZ head?

[@StreetFXofficial]

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

[@johnurbanek1027]

@@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.

[@lsswapeverything2518]

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

[@davidt1621]

The one percent yield isn't measured against thickness. It's measured against the block's weight converted into Newtons, because a Newton is the universal unit of measure for force. It can be compared to the physical magnitude of pressure in the engine once that's also converted into Newtons. The point is, iron is more dense with a higher melting point and more magnetic resistance, so it can withstand more force than an aluminum alloy block of equal volume (same size). That's why the aluminum blocks are so much bigger. The great thing about a smaller block is that if you're working with a smaller engine bay, like most stock-chassis on 4-bangers, it gives you more space to add modifications, like headers, turbos or a supercharger, cold air intake, etc. He's right about this though: the bigger aluminum alloy billeted block engine will move less, probably because it'll be mounted on both opposite sides of the chassis' frame though lol.

You would imagine that expansion and contraction would be much worse with aluminium than with a cast iron block, if the block gets taller as it heats up then you lose compression.

[@EvenTheDogAgrees]

Yup, volumetric expansion of aluminium (0.000069) is about double that of iron (0.000035). See www.engineeringtoolbox.com/volum-expansion-coefficients-solids-d_1894.html. That said, car engines don't run hotter than about 250F (approx. 120°C). Source: www.globalcarsbrands.com/hot-car-engine/ Plug in the numbers here: www.easycalculation.com/physics/thermodynamics/thermal-volumetric-expansion.php and use 1000 for the initial volume to get more precise numbers since it rounds off to 2 digits after the comma. You'll see that if you heat up a car engine from freezing to this temperature, your total expansion will be 0.828%. So you're left with 99.18% of your pressure. That's 1/1.00828, in case you're wondering why it's not 99.172. In short: if I were you, I wouldn't worry about it, since some random Internet geek has already worried about it for you. ;)

[@mrw1160]

I mean the gen 2 Volkswagen 1.8t, the block is sturdy enough for over 1,000 horsepower reliably if you have a few mods to the engine, however if you want to see 3,000-4,000 hp for some reason billet aluminum can handle it.

[@JonJenkinsDesign]

When you are removing large chunks of material from a big block of Aluminum like this engine block this causes a lot of movement dimensionally in the work pice so it’s at least a three or more step process before you can start bringing it to size. Can even have to go to heat treat to allow it to normalize. Not a easy job takes lot’s of skill.

I thought the answer before I watched the video was that machining is the way to go for short runs and casting was the way to go for larger production. I think that was probably the right answer after I went looking around the internet. I didn't find anything that suggested cast aluminum was not as strong as the aluminum that a billet was made out of. Overall the video was entertaining even if it didn't address the issue posed by the title very well. I was curious what kind of cars these engines were being built for. 2000 hp was around twice the hp of a Formula 1 car and about three times the hp of an Indy car but it was much less than the hp of a drag strip car.

So, the alloy is forged into a block then billet/milled/CNC machined into an engine.

Its amazing. Could some1 steal that solidwork files for me pls? 😂😂

[@reallife4598]

The hardest part is the input of the location like oil passage

[@slickrock1371]

So the first statement made by the interviewer was wrong, these are not "blocks of solid alloy?" They are blocks of aluminum forged (hammered) and then cut into blocks?

[@slickrock1371]

@@StreetFXofficial not your fault. I was curious, but the interviewer confused the issue of what a forged block is. I'm still curious about the forging. Do you start with let's say a 120 lb block of alloy, forge and cut it into a block that would weigh 100 lbs cast in the same size? The benefit is that the structure of the metal becomes more dense, tighter crystal structure when forged/hammered vs cast?

How long before we see the Billet manufacturers going to Laser Scintered 3D printed blocks and heads. I really do not have the materials knowledge to hazards a guess but both SpaceX and Blue Origin are 3D printing rocket engine parts. I would think the machinery would be a be a lot less expensive as it does not see anywhere near the stresses. As an aside. I worked with a guy that wrenches for race team out of NE Illinios. One type of car they run has Hart 4 cylinder engines. Heads and blocks are unobtainable. They had a new head designed. Patterns 3D printed. They then had new heads cast and machined. These are cars that require coolant. A straight to 3D printed head would cut a lot of steps. It would still require a certain amount of machining. I really can"t see it being weaker than a casting depending on the alloy used plus no core shifting.

I wonder why they bother with patterns when it’s now possible to 3D print the mould the metal will be poured into. When you want to change port shape etc it’s done on the computer and just print and pour another. Need to check the internal shapes? Just section it on your wood bandsaw.

[@mpetersen6]

@@henryblack3974 If you are doing multiple castings it's just easier to print the castings. You can always save the patterns. Between 3D printing with powdered metal and billet at this point in time billets probably a better way to go. Even for a head with coolant passages machine the head to say 90 to 95% and weld the passages closed with a filler plate on the top side of the head. Or just do the head in two pieces that bolt together. Besides this technology is changing so fast.

[@suprasport9118]

Wow!!! Did he say 4 cylinders 2000HP?🙀🙀🙀🙀💯🔥🔥🔥

[@hopsricebarley]

if 10-12k hp is possible on an 8 cyl...why is 2k on a 4 so wow?

Very well done, very interesting, We're is your Siamese cat, I have a chocolate point, Siamese cat, I am in the UK, Great video's

Lol, he's chilling outside on the balcony, he's still upset about me going away for summernats last week :P

@@StreetFXofficial That's great, I got a lead for my cat, But he will not let me put it on him, He does play fetch all the time, Have a great time, Keep the video's coming, Thanks Dave

Thanks Dave :) the Chairman is a blue point tonkinese, related to Siamese :P They're both known to be dog like so the lead should be no issue. Just put the harness on And let yours get used to it in the house for a few hours a day (make it one of those thin ones that doesn't restrict movement much - check out @chairman.meoww for our guys Insta, can see the type we use).

They are great photos, I will have to do the same for my cat, Thanks Dave

I'm 48 years old, I guess it's probably too late to learn engines. It's either that or dentist school... I just had a tooth pulled ,my engine overheated on the way . I was thinking it would be cool to be able to fix my own engine... as cool as being able to fix my own teeth. Plus ,you are really helping people by fixing their teeth or their car engine. Noble trade. Peace
