Mark from Mazworx is a great guy. Over a decade ago I sent him an email asking questions around my SR20 build and he took the time to get back to me and helped me out. The local guys in Australia didn't want to talk unless I threw money at them first.
No one works for, sure talking is cheap but if 1 is busy then 1 must finish their work before they take on other work.. So never forget that, and lets not forget that YOU don't work for free unless you live in a world were everything is provided to ya/use to hand outs. Time, water, electric, shelter, food and medical isn't free yet.. Mazworx does great work from what I see, and so does Larry's power out of CT, but either way being a machinist (in any industry-auto/aerospace) is very hard work and very precise work, thus 1 shouldn't be bothered doing emails and phone calls and running machines at the same time just saying unless 1 is READY to spend that $$$.. Speed/hauling ass cost $$, thus 1 has to be prepared or learn to DIY and buy the equipment and or make friends in the "machinist world"..
@@jm361 Every business has an element of pre-sales, that's talking with potential customers. I wasn't asking for a hand out I was asking their recommendation, they were happy to give it unlike others that didn't.

Agree, but have you seen HPAs video with the 1400 hp Porsche 968 engine? ... That was awesome as well. The video with the Subaru time attack + drag car was amazing as well (but not so much about engines)
I got this crazy idea off making a 2 stroke 8.2 liter inline 6 billet aluminum 2 stroke diesel. Inline 6 with each part of the crankcase baffled off like a sled engine and oil feed to rods like skidoo 850 etec dry sump feed. Machine runner ports up from the crankcase mad a Coats rotary ball valve exhaust valve for a uni-flow 2 stroke. There woulds need to be enough bore spacing for the parts of make it with individual cylinders with big studs and a splite crankcase. i got on the horn with a Dart racing rep and explained this 2 stroke design idea i was running through my head and boy i had his attention for a while. Any thoughts on this?
Mazworx is no joke. I have been running my 370ztt with the new Mazworx engine for 3k miles. No more blown headgaskets at 25psi of boost. It's a whole new animal.
You are always so detailed on your questions, and get more info than anybody I've ever seen keep up the awesome work. And just curiosity maybe one video we would love to see your own personal project car and you to go over it. Thanks a lot for your hard work keep it up you're doing great. Peace, love, boost.
I woulds need a block with more bore spacing in orger to cut ports into it.:www.4btswaps.com/attachments/2cyclesbc-jpg.6839/. I heard the aluminum 2JZ are poppet valved u-loop scavenged 2 strokes and can run dry sump with oil injection.
This is one of your best interviews mate. You always do well articulating your questions and this american fella is well in the game, great with detail and full of knowledge. Awesome. Cheers man!
in the mid 90s i had one bloke talk to me about squish and getting the piston as close to the head as possible. i did exactly what he told me and I could run 23psi on 98 and never ever heard any ping out of that engine
Only problem is that is the quote "easy" thing to and with hot rodders looking for budget solutions is always the norm. However the answer is more nuanced and high octane fuels would solve that, RON 98 is about 93 octane in the US and not race gas. In California it's 91 R+M and in places like Utah, it's 90 R+M. My favorite solution is water-methanol injection actually not "modifying" the quench area, the problem is the source fuel.
By the time you hear it pinging inside the car damage is already being done. It can even ping long before it is audible that is why you have knock sensors. 23psi is nothing for 98 RON petrol, I was running 30 psi at times on 98, you just need to prevent pinging with fuel, timing and air intake temps.
why not build a combined head and block from billet. fit valves in the head section by putting your arm up through the cylinder. and installing the pistons though the bottom ? .
and change the comp ratio by stroke and modifying deck height. is a combined head re-usable after failure? how do you inspect it without removing the bottom end
Problem I see with This idea is the amount of maching that can be done to the valve angle, and or seat area, as well as maintance to valve and chamber maintenance
Squish definitely adds the needed chaos burn factor. My 1600 pushrod Ford has the combustion chamber in the piston and the valves sit flat on a flat head face(no head chambers). To up the compression for a 1600 you put in the 1300 pistons. Cool design by Ford... 😎👌
i know nothing about cars but when someone talks about “cylinder sleeving” is it just what it sounds like? providing sleeves to help support the block at high boost pressure?
They don't at this stage. I can't speak for Maxworx but would imagine it might be something they could do for you on request though if you're interested :) -www.mazworx.com/store/p/84-Mazworx-SR20-Billet-Aluminum-Prepped-Block.aspx - Taz.
I get the feeling that this guy was the wrong person to ask about billet blocks. He seemed to know more about the power production though. I especially like the discussion on squish pads and bore size. Do you get anyone making CNC pistons to match head surfaces for maximum squish? IE the pistons in my AU have a slight dish, but it's perfectly round and the squish pads are not, it appears that the pads are not as effective as they could be
Seems to depend most on the piston to head clearance in the quench/squish area with the critical clearance being, IIRC, roughly between 20 and 40 thou' (0.5 to 1.0mm), depending on engine and, I suppose, rod material and rpm.. With more there is a bit less turbulence produced but the compressed gases aren't trapped to the point where they detonate or pre-ignite and when it is less the 'quench' affect of the cooler head and piston top pulls the heat out of the fuel/air mix fast enough to prevent ignition. A few years ago there was some experimentation with 'fire slots' (can't recall the specific term) machined from near the outer edge of the quench areas towards the spark plug area. IIRC, the theory was twofold, at least, with the gases in the quench area being 'squirted' towards the spark plug increasing turbulence there and b/ the slots would speed the flame front into the quench area around TDC. Again, IIRC, it was found that less timing was required, which would suggest combustion improved. Anyone tried this or got updates on whether it is still used or fallen into disfavour? [edit] Seems they are also called 'flame'and 'Singh' slots - aftaer a patent holder. More discussion here - speedtalk.com/forum/viewtopic.php?f=1&t=5907 - and here - rsmotorsport.com.au/forums/viewtopic.php?f=13&t=1272 - however it seems to have most value, if any, in higher compression engines with large domes that interfer with the flame front.
It’s a lot easier what they are in a picture, but I’ll try to explain. It’s the area on the sides of the combustion chamber that is flat with the head deck.
Why has it not been brough forward to have a relief in the head that the sleeve can slot into thus giving no weak spot for the combustion gases to get through????????? and
People always wonder, would a billet engine block work in a street car, especially one daily driven to get milk, eggs and bread? Or, are these engines only for race applications where it will require rebuilding? Even I dream about having a billet block for a street car even if its not the best choice.
apostate001 don't see why not, it should be stronger in all aspects compared to stock aluminium cast blocks and they are fine for many high power production cars
If it’s a wet block with all original oem mounting points? Definitely In fact it would be better than any oem block then because it would be lighter and more corrosion resistant than iron blocks
If it's possible can you do a how to on rebuilding and blueprinting a 2jz for increased power? I been looking for a step by step (or close to it) on the jz family but it seems like its a dark art.
Hey TJ, you can actually get this knowledge instantly as we have exactly this in our Practical Engine building course. You will learn the steps that we deem important when building a performance engine that are not all done on factory builds, and then this knowledge is demonstrated via an actual step by step engine build. The 2jz is the first example we have as a demonstration. If you have any more questions email me: support@hpacademy.com You can find the course here: www.bit.ly/PracEng - Taz.
High Performance Academy May I ask how much for the block? I've just paid 12k for my sr20 no hot or cold side. And I'm wondering how much power and driveability I'm going to get.
We don't sell them sorry Mark, but I think it's listed on Mazworks website and there might be a few others out there making them for SR20's as well that have prices listed I think. I'm sure the price is much better than what they were going for 10 -- 15 years ago either way, much like dynos - Taz.
The Red Demon is slower than the car mentioned here, but you can't really compare them as they are very different cars with the main point being that the Red Demon is AWD rather than RWD. Both great cars though! - Taz.
High Performance Academy Oh I was talking about the Jett Racing '04 Eclipse with a billet 4G63 that ran a best ET of 6.52 and best trap speed of 223 mph. It holds the world record for fastest 4-cylinder, although not the quickest.
Ahh, I'm with you now. Last time I posted a vid of Colins I was corrected by someone to say he was the second fastest, so I guess now he would be the 3rd fastest. This car has since done a 6.456 pass and is undergoing some testing at the moment with a compound turbo setup. Checkout the Mazworx and Tuned by Shane T channels for more info on that. Unless you're in the drag racing scene yourself it's hard to keep up with results as some of the teams are not the best at social media updates so you end up getting the details from 3rd parties - Taz.

great interview , keep up the great work.

Not bad review. Hope closed deck vs open deck vs hybrid deck, next.

why not build a combined head and block from billet. fit valves in the head section by putting your arm up through the cylinder. and installing the pistons though the bottom ? .
interesting question. lycoming and continental i believe DO make such a head/cylinder combo in general aviation. ie. Cessna 172, Piper Archer, etc.
and change the comp ratio by stroke and modifying deck height. is a combined head re-usable after failure? how do you inspect it without removing the bottom end
Problem I see with This idea is the amount of maching that can be done to the valve angle, and or seat area, as well as maintance to valve and chamber maintenance
Sorry machining
could always move forward and try actuated valves the fit in from the top kinda like the f1 tech

Jamaica checking in.
"So can you tell us how to remodulate the phase attenuation in the Flux capacitor?"
i know nothing about cars but when someone talks about “cylinder sleeving” is it just what it sounds like? providing sleeves to help support the block at high boost pressure?
How much is it to do a k24 block? I need something I can rev to infinity and beyond
Mercedes Mob k24 motor his ran 6.6 on oem block and head which to me is the fastest 4 cylinder in world
sameer jura Exactly!All these other cars is running non OEM blocks and claim the fastest SR20 or fastest 2JZ.....
sameer jura jet racing is into the 6.2x with 4g63
One thing thats got me confused is on their billet sr20 block is if they still have all the water jackets and whatnot so you can daily them?
They don't at this stage. I can't speak for Maxworx but would imagine it might be something they could do for you on request though if you're interested :) -www.mazworx.com/store/p/84-Mazworx-SR20-Billet-Aluminum-Prepped-Block.aspx - Taz.

Skippy i felt the same way, didnt really inspire me to spend 20k on a billet 2j except for the fact that mine, you know, could break.
The key is ductile iron sleve👍
Yes they have changed the game a bit over the years! - Taz.
Cut ports into them like this:www.4btswaps.com/attachments/2cyclesbc-jpg.6839/
So is the squish area prone to detonation because of the shape or because of the higher compression ratio ?
Seems to depend most on the piston to head clearance in the quench/squish area with the critical clearance being, IIRC, roughly between 20 and 40 thou' (0.5 to 1.0mm), depending on engine and, I suppose, rod material and rpm..
With more there is a bit less turbulence produced but the compressed gases aren't trapped to the point where they detonate or pre-ignite and when it is less the 'quench' affect of the cooler head and piston top pulls the heat out of the fuel/air mix fast enough to prevent ignition.

What is squish area? Could you do a video?
It’s a lot easier what they are in a picture, but I’ll try to explain. It’s the area on the sides of the combustion chamber that is flat with the head deck.
Dam I really just wanted to see the blocks 😂
Mark radical 100%
Why has it not been brough forward to have a relief in the head that the sleeve can slot into thus giving no weak spot for the combustion gases to get through????????? and
SR blocks are known to blow up after 400-500hp. Billet is essential
So you have two cut the block twice? Fly cut everything then fly cut the block without touching the sleeves 5 thou below the top of the sleeve? 🤔
People always wonder, would a billet engine block work in a street car, especially one daily driven to get milk, eggs and bread? Or, are these engines only for race applications where it will require rebuilding? Even I dream about having a billet block for a street car even if its not the best choice.

We just bought a billet Chevy 434 small block for our team that cost $11,500 just for the bare block.
If it's the second fastest 4-cylinder I'm pretty sure the 3g Eclipse with a 4G63 engine is the fastest.
