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

Published 2020-01-09
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 ❤

    Excellent video. Takes some of the mystery out of of billett engines. I shudder to think how much one costs though.

    I didn't realize people began making billet engine blocks that's amazing. Seriously cool engineering!!! But in 99% of cases, a stock block will do ya just fine.
  • Its like a Sports Illustrated swimsuit model: Looks beautiful, performs well, and is way outta my league.

    If this guy tells me something about engines, I'll believe him because once you start milling aluminum blocks from billet, you're not alright in the head :O Keep up the good work!
  • This is my dream job. Hope I can find something similar to this once I finish my engineering degree.

    "What is a billet engine, and when should you get one?" A billet engine block is a precision machined chunk of awesome, you should get one right now. end credits

    "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.

    That's a cool job to have. I've worked with some of those materials, but never a block of aluminum like that. Only variable now is the raw block quality

    Brilliant work. I hope one day i get to buy a complete engine from you.

    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.

    Very interesting loved the catia view learned a lot beacuse of ya guys thx!
  • most beautiful thing I'ever seen, what sweet machine , making the block

    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 am so glad Hard Metal and Rock Music is coming back to Videos. Man. 2020 is looking to be a GREAT YEAR!
