Thanks to all for the suggestions, we'll be working on figuring out why the pan isn't working as it should, we think it has to do with over baffling. We also have it overfilled during the track outing and it didn't help but this is how we do things, test and then fix!

[@ianm432]

Bolt some plexiglass to the pan filled with cooking oil to simulate hot engine oil, a gopro looking into the plexi and replicate the g-forces and study the footage. I don't know how you'll replicate g forces... Minibike spinning a merry go round at a park? Ride the tea cups at Disney? Spin in circles holding it until you barf? Small scale astronaut style centrifuge?

[@TheRedzero2000]

Get an Accusump.

[@austin5806]

Baffles are not enough, you need baffles to control and trapdoors to block flow towards the timing chain area. During gforces towards the timing chain area, almost all of the flow must be blocked, during forces away from them they must be allowed with hinged doors and a block off plate. I have had success on my car which pulls around 1.2g's with the original windage tray to prevent frothing, a baffle plate to slow the flow around, and the trap doors to block the oil from all running into the timing area. An accusump type reservoir might help as well in the event of short term failure of oil control systems.

[@austin5806]

Here is an image of my setup to give you an idea of what should be suitable. i.imgur.com/15ro6qS.jpg All of these plates must almost touch all edges of the pan.

[@sintwo0one]

Speed Academy you guys fucking suck...

[@hutchdw77]

Time for a series on dry sump oil systems...

[@austin5806]

Baffle and trapdoor. wont need dry sump. They are probably about to do a video about how to rebuild a k20 with spun bearings, because they did a ton of damage during this video. Also that fuel cutoff needs to be raised in Kpro, the k24a2 is good for 8300 at least.

[@stephencain3467]

@@austin5806 well it already has baffling and trap doors soo

[@dirtslider1997]

FlyTheElephant all thats been done so...

[@ghettoflyer]

I don't know if any one still makes them but a swing pick up could be a solution as well. (Swing pick up is free to move around the oil pan. The car turns left, oil goes right, the centrifugal forces excreted on the oil pick up drives it right as well, allowing the oil pick up to stay with the oil.)

[@patx35]

They intentionally did not go with a dry sump system because buying just the dry sump kit would cost way more than the whole motor itself. It's probably cheaper for them to blow a motor than it is to go dry sump.

[@Karza_357]

This car is so beautiful. Also the backseat is getting wild @ 9:10

[@TommyBlazeHD]

I noticed it flapping around @4:00 mark as well.

[@joeblow9979]

It is beautiful

[@ChrIStupidX]

That's a huge problem... General rule of thumb is 10 PSI per thousand RPM.

[@1998BmwM3]

The low oil pressure issue may be the reason why the car doesn't feel strong coming out of corners. With low oil pressure vtec won't function right.

[@vincevegacustoms754]

I wonder if they baffled the pan..yes i dont watch all of their vids got kids to feed

[@mentals555]

@@vincevegacustoms754 yes they did. I'm sure you spend more than 15 minutes every couple days doing something less worthwhile than watching these videos, maybe it's time to evaluate your priorities

[@ASBP12]

M3NT4L5 speed academy > 15 minutes of doing nothing 😂

[@austin5806]

You gotta baffle and trapdoor oil pans on ks if you pull over about 1.1 or 1.2gs towards the timing chain.

[@austin5806]

In fwd k's its left turns. In rwd k's its under braking.

[@martinhayes5087]

I'd get the oil pressure issue sorted otherwise you'll have a dead k series relatively quickly 😬

[@Van_frederick]

even at 80 psi?

[@mashedpotatoes5323]

@@BEYTEK serious question, would adding more oil hurt anything?

[@austin5806]

Yes adding oil above the level of the factory windage tray will cause large amounts of frothing which will cause air bubbles to be pushed through the oil passages which is almost as bad as running totally dry.

[@mashedpotatoes5323]

@@austin5806 that makes sense

[@austin5806]

I dont know how much more than the full level is above windage for k20a/a2. But they went to a lot of effort to design a great windage tray for it.

[@desmondscook1]

All the hard work paid off. This is going to be one hell of a street car!

[@ArmstrongRacing]

Guys invest in an Accusump! You precharge the unit and when oil pressure drops the oil charge in the unit will maintain the system pressure.

Another great video from Speed Academy! Good stuff boys! Is that the Deboss truck i see in the background? Quattro Debocho Audi review in the works? That would be sick.

[@someonesomewheresomdeday]

Happy for you guys. When I had my ep3 I always put an extra full quart in on track days. I think it was purely anecdotal but we always said the k engines take forever for the oil to get out of the head and back go the pan. It's not that there is a windage issue, rather a return issue. Not sure if that's the truth, but it's the gospel we followed and never had an issue. Amazing car guys. Pure jealousy on my end. It's the perfect triangle car (speed, handling, looks)

[@sniper007x]

Perfect setup for downhill/touge thinking of doing it to my z3

[@etwoodson213]

I really think a episode on suspension setup would be awesome, more so around the premise "understeer = soften front" etc. Just an idea

[@chris__whips]

This is awesome! A very unique swap

[@94tegLSatMSC]

Great work on this series guys. As someone who has tracked hondas for years I'll say that the oil pressure dipping to 5-10 psi is a little worrying. I'd bet at small tracks like your home test facility it will probably be fine but going somewhere like Buttonwillow with a 100mph high G load sustained corner you'll be in a world of hurt. I run the extra capacity Moroso pan on my K20A engine on Hoosiers and I don't have issues but I assume you dont have the room for that. Maybe work with Kmiata on a new baffle design. Cheers.

[@LikelyCandidate]

I think you might be right about over baffling. With the motor sitting on the slight angle, all the oil get pushed up the side of the block, and the trap door is not going to want to open to let it get down to the pickup. I would take the pan off, have a few smart people look at it for a couple of beers, then think about moving the pick up to the right if possible/practical, and add an accumulator.

[@NasnasFilms]

This realy makes me realy want to finish my Turbo Miata(diff broke)! Waiting for parts right now. Trackdays for days in the spring!

[@The_True_]

Watch out for that loose back seat, it's flapping around in the turns. That stack cluster is the secret sauce, looks like it came that way from the factory amongst the interior pieces! And all that didn't make the Toyo's chirp once, great grip! 👍😎

An oil accumulator should help with the starvation issue. Good job on finishing up the project, and getting it on the track!

Jakob Kerr yeah it increased the oil pressure when you add shims

Congratulations speed Academy on this build! were you guys at Cayuga?

[@feelthatfeelthat]

I used to rock an H2B (prelude motor with B-series trans) back in the day. You might have to put more oil into the car. I had to put 6 quarts of oil instead of 4.1 quarts which is what the factory called for. I had zero issues over the few years and about 50k of driving it.

[@whiteshadow299]

Love the sound! Car is awesome! That rear seat tho lol 😁😁❤️

[@ianmccormick247]

I have heard that Ballade Sports in SoCal were having oil issues when swapping a k-motor into a S2000. You might want to reach out to them or research this phenomenon.

[@Imonursixx]

Yes the oil pressure loss is a issue especially on a k that very dependent on oil pressure

[@PressurenFlames]

I'd be happy to see some turbo-TEC (and solved oil pressure issue) :) Awesome build.

[@s2kwidebody]

Sweet ride.

[@aceoboy]

maybe an accusump will help with stabilizing the oil pressure on corners and also to stop start up wear with pre oiling

[@fourtwentynine42]

6qts is what i use + oil cooler. had the same problem with my ae86

[@moereefer]

Add more oil about a half quart

[@Drink_Daddy]

was going to say, he needs to add half more oil. I had this same problem back in the day with my old k-swap.

[@seanhenry8030]

Accusump, or some other oil accumulator system is what I'd recommend. Great insurance for a couple hundred bucks. Significantly cheaper than a dry sump, particularly if you're going to buy it in kit form. Below 10 psi seems dangerously low for a high revving engine, I remember there being some shade tree mechanic/weekend racer rule of thumb of wanting around 10 psi per 1K RPMs. I doubt the engine will blow immediately, more likely it'll be a cumulative damage scenario. Otherwise keep up the good work, K240 is sweet.

[@therealboofighter]

[@TheInfectedWreck]

Canton Accu-Sump would do the trick for that oil pressure issue, keeps cost down and piece of mind.

[@capnthepeafarmer]

You don't have to get a dry sump, you can get a canton oil accumulator. That will prevent oil starvation and be way cheaper than a dry sump.

[@Dolby109]

For the short term you could probably just over-fill the oil a bit. In the long run you might want to go dry sump or find another solution.

[@GibbysGarage15]

3:54 Aaamazing and everything seems to be working great *back seat tears off* :P

[@Fuzion180]

Could add a tad more oil into the engine so it's just over or check the sump baffle design, I know here in the UK there's a K20 sump baffle brand called Clockwise motion which are used on track cars

Dude, that car is sexy af. I have ALWAYS wanted to get my hands on a 240, but they don't come up for sale often and when they do they're outrageously priced.

[@slverbuet1791]

ANY TIME YOU SWAP A K AND PUT IT SIDEWAYS YOU GOTTA MAKE A CUSTOM BAFFLE SYSTEM BECAUSE OF THE ANGLE OF THE MOTOR AND THE WAY THE GFORCES PULL THE OIL AROUND THE PAN REACH OUT TO THE BOOSTEDBOIS THEY HAD THIS ISSUE AND THEY FIXXED IT

[@hhkimsd]

I think I remember that you had to install the motor at an angle ( top of motor tilted towards passenger side) which would tilted the oil pan too. So maybe re-engineer the oil pick up to be biased towards the passenger side of the the pan? Otherwise straighten block and put a power lump in the hood...

[@NoNoRc]

Oil starvation via air bubbles is still the major issue here despite the pan being baffled so it’s safe to say we can stop beating that dead horse with stick. Process of elimination would be the most efficient way. Not enough oil, or possibly having to run a thicker weight? Check to make sure there are no leaks in the pickup assembly. Dare I mention the over silicone issue we’ve had in the past 🤭.. Sorry, lol just trying to help

[@TazjukieGaming]

the Sump needs some trap doors to eliminate the sloshing of the Oil, and keep it more level.

[@adamsondergaard8159]

Like seeing it complete, or damn neer i should say!

[@DeathOrGloryRacingBC]

Most serious race cars end up with dry sumps, the faster you go the more you need one. That said, if you log oil pressure with an aftermarket sensor I think you'd find most cars have alarming drops in oil psi on track if you're going Harry flatters (for normal guys who don't know this). I suspect this is a combo of a longitudinal layout that's not ideal for the oil pan design and the aftermarket sensor reading more accurately than factory. I've found that baffle pans are a band-aid unless you have trap doors inside and even then they have their limits. The BMW shifter assembly is a known problem, I don't know what you ended up going with but it looks short relative to a normal bimmer option, though I don't have another S14 to compare to ;). Short throws on these boxes make for notchy engagement, the best explanation is available from UUC somewhere out there in the vast expanse. You want to retain some leverage/length with these boxes. You guys also weren't using the typical BMW shifting style to prevent money shifts, also recommended by UUC (especially to those unfamiliar with the getrag/VF boxes). I'm warning you gents, respect the money shift or buy spare valves and a head gasket.

[@PK-R]

Proper cool how you break molds and have got s14 as a grip car and e46 m3 as a drift car. Not your typical conventional youtuber!!

[@DresRacingChannel]

Damn i love that car, K series motors are the shit i can't wait to finish my MR2 so i can have fun with that K series.
