Good job and great video! I would assume the reason for your main caps cracked, was due to crankshafts flexing. I am making well over 500 hp and still running the stock caps, which got me thinking why mine haven't cracked yet? I have installed a stroker kit that uses a moldex crankshaft that is way more sturdy then the oem one's. Just a thought! so let me know if yours is out of shape. But I must say that you have got me thinking 🤔 By the way, sorry that I still haven't replied your mail. Will get back to you Best Regards Bassam Rammaha Denmark

I appreciate you sticking with the BP and showing what is possible. Obviously it's far from the best engine out there for making the most power, but swapping in a completely different powerplant usually involves a ton more fabrication work and money, which are things most Miata lads like myself don't have. You've built this car in your driveway and that is one hell of an achievement considering the sort of performance it managed to dish out.

An engine that gets little acknowledgment in aftermarket are the Suzuki M13A, 15 etc. They are far better than all the 4 cylinders around this time, yet they have little aftermarket support. I guess its because the cars they came out in. These engines have 4 bolt billet caps from factory.

@sepg5084 2 жыл бұрын

Maybe a slightly more aggressive cam with a slightly milder tune/boost might reduce your mid range torque values while retaining your top end power. Might make the car feel less power but it could ease the stress on your powertrain and drivetrain, plus it may also reduce wheel spin when launching the car.

@jinmannn Жыл бұрын

Unsure if you'll see this message on an older video but I would be very interested in seeing how your interactions with a machine shop would go. I do intend to build my stock miata motor to something fun and would love to shoot for 450+ whp but I have 0 experience working with machine shops (aside from work) and would love to see how I can be absolutely prepared to bring my block/head in for work without making the shop's job harder. Love the videos Greg!

@TheCarPassionChannel Жыл бұрын

Don't have time to give you the full breakdown but it's pretty much the same as a stock rebuild if you're talking about the block itself. Let them know it's for higher power with boost, if you're doing upgraded main studs bring them the block with those studs.

Just a thought on the rod bearings- Since the oil path for the rod bearings goes through the crank, as the crank pushed away from the top bearing (where the oil feed is,) the crank and rod bearings would both lose oil pressure. This could be the cause of your excessive rod bearing wear. Do you happen to have a log of the oil pressure before and after the failure?

@TheCarPassionChannel 2 жыл бұрын

That's a really good point. And unfortunately no, I don't have oil pressure hooked up to MS

I know everyone knowledgeable in the field says BPs don't like to rev and don't bother trying -- which I believe to be totally correct, but yet high rpm is fun even if there ain't a whole lot of power (if any) to be had up there... my question is: Would billet main caps be a good idea for a build targeting reliability for a mostly street-driven Naturally Aspirated BP4W aiming for 8000-8500 rpm fuel cut? For that matter, is Maruha's stock stroke crankshaft a good idea? Power aside. I'm one of the weirdos OK with smol power for street car miatas seems like. The stock BP crank has a reputation for being about as stiff as a wet noodle at that RPM, so just asking some stupid questions about how to get around that.

Which cylinder head studs are you running there? Are those already the Chrysler one, as they look pretty beefy? Last time on dyno I had 450Nm at 4000rpm and fuelsystem was pressurized, so I belief my current ARP head studs didnt hold the head in place. Now I think about to swap them to Chrysler studs (220k psi vs. 190k psi).
