Drilling The Oil Pan For Turbo! (Broke & Boosted Ep5) 

Instructions not clear, drilled the wrong oil pan and got fired from mcdonalds :(

For anyone wondering, you drill it in the same spot on the 1.8L cars as well!

dude the hose on the drill is genious. mad props.

I drilled my sump today and nailed it thanks to this video. I honestly watched it 30 times. Thanks Craig 😉🤙😁

Helping Greg with some questions here... *I have a turbo 1.8* I'll post the one I'm working on soon. 1) the oil does not come out when the drill goes through because the car is lifted or on jack stands in the front so all the oil is resting at the back of the oil pan. 2) The shavings not trapped by the grease on the drill bit flutes will go into the oil, some of it will be drained out and you can spray mineral oil or brake clean to help flush it out when you are done. 3) The oil pick up screen and oil filter won't allow the chunks and fine particles to reach you engine bearings or hydraulic lifters but the turbo might get some so do plenty of drains and refills 2-3 work fine for me before I fire up the car. I mean a journal bearing or ball bearing turbo is expensive/ish unless you are running a China Charger... Oil is cheaper than a Churbo or rebuilding stuff. 4) don't use a step drill bit(Christmas tree drill bit) they will hit the pick up tube, don't ask how I know. 5) have a spare threaded plug incase you need it to block of the oil drain hole. 6) not necessary but you can change oil and oil filters after a couple hundred miles 2 times works for me. This makes sure anything trapped can find it's way out. 7) happy boosting.

Well done and well explained as usual. Great job doing this video! You're always thorough, but keep the videos concise. I used the grease trick to fix my #4 spark plug hole when the plug kept being emotionally distant from the head...works every time!

Sweet video man, really appreciate your effort in making these.

lol love watching your videos man. i literally laughed out loud when you found your tool at the end, i leave mine in the same spot lolol. i actually just found out about your channel about a month ago when i was doing some research on cost effective turbo builds. currently about to finish my 1.6 rebuild and cant wait to break it in and boost it. keep up the videos man, im subscribed and enjoy your work!

Great content! I have a 93 Miata LE that is in need of some power, so these videos really help my research. I like your idea of installing one part at a time rather than doing a complete turbo build in one shot. This idea works well with my college budget. Time to find a used wide band. Thanks for the videos and keep them coming!

Dude...awesome video. Short n sweat, to the point, and most of what you talked about applies to almost any turbo install on a vehicle. I'm about to install a turbo system on a 4 cyl Chevy S10. Thanks bud

I will be definitely using the hose on the drill trick, makes it a lot safer. Oh and finding tools in the engine bay is something I believe every car guy has experienced a lot haha.

Thanks for posting! Appreciated the useful tip about the grease on the bit and tap to catch the shavings.

congratulations, you have the best how to turbo a miata (or most cars) video. thank you!

Today haggard garage, Speed Academy, CarsandCameras, and now TheCarPassionChannel all uploaded today :D perfect!

"Just take it nice and slow..." proceeds to full send 😂😂 Thank you for this brother! I'm at this crossroads on my SC300 build and it's scaaaaary. I will eventually turbo my 90 Smurf Blue Miata as well which is another reason I stumbled onto your channel. Looking forward to learning more from your experiences 🤙

@TheCarPassionChannel I am so grateful for your videos

Excellent video. Hard to find such a clear HD tutorial on oil return lines

Smart kid. Nice work with the hose on the drill!

Thanks for this man , have to do this in the coming month or so this is a good reference

Nice video great job as usual Greg!Greetings from SwedenKai

always great content can't wait to start my boosted Neon build

Very informative, keep up the good work.

How do you feel about those dipstick drain installs, compared to drilling the pan?

Awesome video again bro!!!

AhhHHHhHhHHHH!! Its so scary. This is really the only thing im afraid to do

damn, I'm coming back to this video to remind me what size oil drain I have, my broke and boosted clone didn't start having problems until 5 years after. solid for

Would it be bad to drill and tap the hole well before getting the kit? like drill/tap then plug? just so there's one less thing to worry about?

I’m not gonna lie I was gonna work my way up to 3/8 NPT by tapping slowly. But the drilling seems a lot easier 😂😂😂

Great video very helpful plan on doing it this weekend.

Usually you pressurise the pan, ie compressor or a reverse vacuum cleaner in the oil filler. Or as a last resort, or both, put a vacuum cleaner hose near where you are drilling to suck the swarf.

may the force be with you

You can hook up an air compressor on low pressure or even an air mattress pump to a crankcase vent so when you break through the pan, the pressure will blow the shavings outward.

Looking forward to the next vid!

A good well thought out procedure that has applications for many devices that has fluid lubrication. My issue is that I need to tap a sheet metal oil pan, for an extra oil drain... without removing the pan from the engine!

Another great vid. Only thing I would of changed is adding a how u got the x mark on the pan. Mine is already done but some others may not know where to measure from. Again, great job.

Hi Greg,I got a question about those drilling bits on the inside of oil pan, that were shown from 7.09 min of you video, they at the end off your thread ,they looked like stuck to pan. what you do with them ? are you trying to take them out or are you pushing them in to oil pan ? thanks and btw. Great job man !

awesome video,who could even dislike this???

You sir, are a hero.

I've never seen anyone drill without pulling the pan first. That is crazy lol. Even with grease. But still is nice to do less work.

So if my car is already turbod and i want to add braided lines i just need a fitting to plug the original return line to oil pan hole?

I know its the most common way to drill the oilpan adn was a nice video to watch, buuut i think im to scared of lil metal swarf on the inside that the grease will not catch. Ok Greg, as im planing to go turbo next year another question: would you recomend turbo charging on a 1990 miata with the short nose crank? No wobbling an the pulley and good keyways till now, but how high is the risk and do you have own experience on charged short nose cranks?

love the videos greg! keep up the good work bud!

Im from Germany and while watching your Videos I just feel really Bad about our Street-Security-laws because every change I do to my Miata has to be checked and confirmed by an institution which makes a selfmade turbocharging close to impossible of you dont want to spend more than 4000€ ... I really like what you do, because it shows what at least might be possible ..

Thanks for this detailed video, explains a lot!

Is this process relatively similar for a Mazda 6, do you know? That's what I've got and I'd like to assume that since they're both Mazdas, the process is fairly similar, but I don't wanna take that chance. I can't find a decent tutorial on turbo-ing a 6.

🤙Bro I live down the block. No wonder why does miatas look familiar lol 😅. Good video

How high do you need to drill it ? I've heard different both ways.

Great video as usual. Any idea of when the coilover install video will be released?

Hey my truck. 2006 trailblazer does not have a oil drain plug is it the same procudure for this as well ?

Not even gonna lie i was scared enough when i had to drill my pan for the oil return that i actually did remove the motor. Luckly though since the sump is the same for the TT and na models it had the flange there just not drilled. The part with supra's atleast is the only way to get a drill in there is if you use a 90 degree piece for the drill. And i just felt more comfortable taking the motor out so when i take the sump off the metal shavings would just not go anywhere. Even though it was a pain in my ass it made alot of the work i did easier. like upgrading my head gasket and head studs it was all easily accessible. Good video!

Bwahahahahahahahahaha!!! Years ago, I owned a 90 Civic Hatch, I left a pair of needle nose pliers in the engine bay...found it when I went to sell it over a year later!!! So I'm not the only one...good vid brother...keep it up...

Thanks Greg :)

What did you use to cap it? I'm going to change the oil on one of my miatas soon and figured I'd I should tap it while I'm at it.

Hi there Greg! Cant say im certain about going turbo/supercharger on my daily 1.6, however the motor is already out and i figured it would not be too rough to go ahead and tap/plug it now. In the video you mentioned plugging it off if you didn't have your turbo to install yet. Any recommendations on plugs? Great videos by the way already a huge help to my two NA builds! Keep up the good work! Thanks Theo

Man very good videos, I will turbo my 90' Miata but I wanna start with FMU and then with Megasquirt, what do you think about FMU turbo project? Can you do a video about that? Congratulations... Miguel Gonzales F.

planning on slapping a turbo on my 1.6. found your videos and just wanted to say thank you for them. btw what are your thoughts on the updated cx turbo kits now. heard some good reviews on them lately

Hey question: why didn’t oil come out all over the place when you tapped the pan? Did you drain it first just for demonstration purposes?

Hey Greg my turbo is using a 3an fitting instead of 4an will your oil drill pan fitting measurements still work for a 3an oil line?

Would it be easier to drop the pan to do it? Seems like it would also make getting the shavings out easier

Good idea with the fuel line.

ok thanks buddy!!:)

At the end of the series (once the budget turbo build is complete). Could you do a separate video explaining what are some things you could do to improve performance. Upgrading the clutch to run more boost, etc.

What happens if you do get metal shavings in the drilling process? Probably best to do this when the pan is out instead of on the car????

hello peter,i d like your opinion on this....for avoiding the drilling and the possibility to do something that it can t be undone ....if we use a filter relocator and connect the oil returning line istead the drilling process it ll be the same?

Puuuurfect :)

Just wanted to post you were correct about the pan. I missed the part where you showed the location where the return fitting will be. Apologies.

What would you recommend capping the fitting with?

this measure is standard? does not influence the diameter of the outlet hose turbo?

What is the drill bit sized used? And what is the tap used? A 3/8ths tap? NPT?

Is this the same miata that you have now?

what do you think about the FMII turbo kit from flyin miata

when learning about turbocharging my future miata what should i study about. Could u give a a small list of what i should be studying about before i do stuff. and could u make a wideband video. I'm really scared I'm gonna do something wrong.

Very helpful!

I see that your are autocrossing, canyon racing that MX5 pretty hard but I'm surprised that you don't have a baffled oil pan. I don't know this car/engine well but you never had issue with oil starvation on heavy turns ? Thanks. On a side note, the inside of the oil pan you've shown looks like a double side wall so may be the trick is there ?!?

I thought 1.8 had blocked off oil feed lines you could use? So you don't have to drill into the pan?

Quick question. How come oil didn't start pouring out when u drilled the hole? Did u partially drain the oil already? Thanks in advance!

Anybody know where to buy one of 5/8 hose barb to 3/8 npt fittings cant see to find it

Could you use a sandwich adapter for the oil return line for the turbo???

What size drill bit and tap??

When you said "keep them miatas ont he road" damn mustang yesterday cut me off and ended up hitting my front bumper... his mustang got more messed up than my miata lol i only got a big scuff,broken front blinker and a small hole in my front bumper lol

where can I best source the fitting?

Hi Greg, Should the hole be above the level of the oil ?

Is it true that the 1.6 handles boost better than the 1.8? Some people say its complete rubbish?

Would the entire broke and boosted build steps work for a 1.8 Miata?

A unibit (step drill) is a much better way to drill a hole through metal. Self centers once started and no danger of the bit striking something on the other side once the hole is made, since the next sized step on the bit acts as it's own stop. Anyone who drills holes through sheet metal needs one (or better yet, a small set set). Try it...you will never use a twist style bit again in sheet metal.

But I ain’t gonna lie that’s a gangster ass way to put in an oil drain lmao

What rims are you rocking on your main Miata (the on on the right of the screen with the roll bar) the white volk look alikes

about how far up or down on the oil pan should i drill? i just to make sure its above the oil level to prevent leaking

ok have have a problem I can't find that fitting that you put in the pan all I find is 5/8" x 3/8" npt. it does not say 5/8" x 3/8" NPT 18 the 18 is not on the picture. do you have a link where I can get one this is holding me back lol

Hey greg I have a question about Hardtop security: I recently got mine stolen sadly, and had already ordered the security bolts and brackets from garage star before the steal. But my question is, is that really going to deter a thief from stealing it entirely? How do you have your hardtop secured? Is there any way to fabricate something to add the 110% security it needs? thanks

think you could skip all this if u get a sandwitch filter adapter for a oil cooler it has a in and out port and goes in between the filter and block

what about other cars i have a mitsubishi galant and i am planning to boosted with a turbo. can this help me?

Hey Greg I was wondering if I could just tap into the bottom of the dipstick tube or is that not going to be a big enough return from the turbo?

If your scared of hitting the oil pick up line its always a good idea to wrap a good wad of tape on the drill bit so theres no way you can push it in too far

hey Greg can you pleease send me a link where i can find the fitting at? cant seem to find that one on ebay

Hi Greg, you'll probably never see this comment but if you do would you mind telling me what size drill bit you used for this? I've got a 3/8 npt return and unsure as to what size hole to drill in the sump? Thanks in advance☺️

Quick question - what did you use to cap the oil fitting?

Nice

Hey Greg I need ur help! Here's wat I hav, 91 Miata 1.6 turbo running on megasquirt 2, 255lph walbro fuel pump, fuel regulated pressure at 40psi. Running great until I replace the injectors(420cc yellow injectors from rx8), I have set the fuel regulator around 100 psi to keep the from stalling. Any advice?

Hey dude is it the same procedure for the oil pressure sensor? just in a different spot?
