Dude that is a ton of info. I really need to review turbo build basics.

[@projectv12bmw66]

Thanks for making this, love your ingenuity

[@TurbineResearch]

Thanks for the kind words 🙏

[@airsoftmann98]

WONDERFUL WONDERFUL WONDERFUL VIDEO!!! I WILL PAY YOU TO MAKE A LIST OF EVERYTHING I NEED & PROBABLY SOME HELP ALONG THE WAY BECAUSE YOU DID AN AWESOME JOB KILLER VIDEO REALLYY BADASS

[@garagefabroart]

Awesome build! Id like to eventually take my M30B32 in my early E24 in this direction. I love driving my car but 180hp doesnt quite cut it.

[@TurbineResearch]

The extra power makes it very fun to drive

[@curtisc7226]

So detailed, this is high quality and should be used as the standard for all turbo build videos.

[@TurbineResearch]

Thanks 😊

[@sergiorodriguez1262]

Great coil over plug set up! I have the same E28 and wanted to know how you wired the plugs up? I’m not going turbo at this time but would like to get more power by having the same coil over plug set up. Do you have a schematic? Again great set up!

[@E30ShedSkid]

anyway to maybe steal your tune? i was thinking of running microsquirt on our euro 733i w/ m106 mani. and it would be a good starting point. nice work!

[@joshuam6828]

I wanna turbo my e34 M50 NV, you show a lot of detail about your setup.

[@TurbineResearch]

I would love to swap a m50 nv into my car they are solid motors and way newer tech than m30s .

[@joshuam6828]

s14sean if you plan on doing a M50 make a video or lmk because I wanna learn how to. I’ve seen how to turbo a car, but I wanna see it done on the same motor I have xD

[@joshuam6828]

s14sean also, if you plan on doing so, that E28 is going to fly!

[@gerryreggea]

Hello, nice build up and thanks I have just seen from one of your comments the documents you provided on the buildup. Thanks if I need anything on my buildup I would hit you up. cheers

[@TurbineResearch]

Thanks 😊 good luck on your build

[@xf2744]

Nice project 👍🏼👍🏼 I really like it One m30 specific question From were do you get the oil feed to the turbo ?

[@TurbineResearch]

X F any hydraulic store will have the fittings. 1/4 push loc hose and 1/4 JIC connectors. As you see in the video I get oil from the back of the cylinder head.

[@xf2744]

s14sean oh i tough this was coolent My fault

[@oh11919]

Hey there. I have an M30B35 e34 that I am building with basically the same ECU/ignition setup as you have. Could I pick your brain a little about how you enabled the 3rd igntion output in Tunerstudio after adding the resisor internally? THanks!

[@TurbineResearch]

Enabling the 3ign is easy (once the modifications are done to the ECU) simply tell the megasquirt how many cylinders it has and it will automatically enable the output. The resistor is easy too just put a 10k 1/4watt resistor in-between the two wires from the stock vr sensor and it will get a clean signal.

[@braydenadams6416]

Hey dude, I'm in Utah as well working on an e28 535is Turbo Build. Would love to pick your brain on some of this, let me know if I could take you to lunch or something.

[@rednecktech9485]

S14sean: was switching from a distributorless system worth it? Do you see any difference in how the car runs out the tuneability? Are you just running wastegate pressure or are you controlling boost through the megasquirt? Clean build my man. I am working on tuning my e24 with an m30b34. I think I am going to do a MLS head gasket and APR studs. I have a rebuilt k27 turbo and 745i manifold. Getting all these parts can be a headache.

[@rednecktech9485]

ARP studs lol

[@TurbineResearch]

Jordan Ebner Thanks man. Yes it was totally worth it. The individual coil packs are very powerful compared to the original coil. It runs so much better on the LS coils and the most noticeable part is that it never misses or hesitates ever. It’s cheap too all the coils were like $40 in the junkyard. I was originally planning on using the stock distributor but I’m glad I went ls coils. Tuning is fine either route but you get more control of timing advance and doing stuff like launch control with individual coils. Now for the past few months I’m running 15psi (~350whp) and no problem on the stock 30 year old headgasket 🤞

[@fitimsinanaj9462]

I wanna turbo my e24 too jordan. I hear the turbo you want to use is small if you eventually want more power out of it

[@572dart]

I would like to copy your build but was wondering what u do with the original mass air box that sits after the air filter?

[@TurbineResearch]

If you get a stand alone ECU like I have you don’t need a MAF. Instead you just use a manifold pressure sensor and use speed density for fuel control

[@12VDHuey]

I'm still ways out before turbocharging my E34 535i. I was interested in going standalone before turbo anyway. Do you know if microsqirt can run a MAP sensor? I'd like to enjoy the car N/A for a while with the benefit of removing the AFM. Thanks!

[@TurbineResearch]

Yes a I run a map on my Microsquirt. I ran about a year NA before I went turbo and it worked great. Definitely made the car run better and felt a power increase for sure

[@thrty8street]

Do you happen to have a build sheet or a thread on any forums that I can follow? Thanks for you help.

[@TurbineResearch]

I don't have a thread on it but I will post more on the channel soon

[@buckdancer6545]

Not to bother but could you message me a small list of what ya got here so I can research a little further? I’m also trying to put together an m30 with a holset hx35. I’d really appreciate it thanks

[@lylemcghee94]

Do you run a flex fuel sensor? Or do you change maps when you change fuel

[@TurbineResearch]

Flex fuel sensor with megasquirt. Works great 👍

[@FStan-co8vv]

Good job, how much did all the things cost altogether?

[@TurbineResearch]

$2000-$2500ish

[@thrty8street]

Great detailed video. Is your car a 535 or 528?

[@TurbineResearch]

535i

[@mowcee1]

Nice build! Still got it? I heard the stock block can handle up to 400 ft lbs of torque, with ARP headstuds. An can be pretty reliable running at 300-350whp for years. Thinking about building one for fun.

[@TurbineResearch]

I still have it. I actually drove it to work today and did a burnout on the way to work haha. It's been fine absolutely zero issues art 16 psi 350whp ish for 3 years. With a clean tune you will have no issues. I also have completely stock everything 30 year old head gasket and head bolts . No probs

[@johnrouk8319]

@@TurbineResearch haha nice! U ever finish cleaning up the wiring 😜

[@michaelcleary5205]

Would you be willing to share the maps you used on the microsquirt about to put mine together

[@TurbineResearch]

Check out my other megasquirt videos they have pretty much everything you need to build a base map

[@rivsrettew9603]

Might've missed it in the video but, where did you get you turbo manifold? Or was it custom?

[@TurbineResearch]

Rivs Rettew it’s home made from schedule 40 mild steel pipe

[@DanielLovelock]

Also I have a build I want to use your identical electronics set up. Have a list for the build?

I don't have a list but this video has most of everything I use

[@eis-zj4qq]

Does that intake manifold fit the m20b25 ?

[@TurbineResearch]

[@SV867]

so how are you metering air with this setup? trying to figure out if i can use MAF+MAP or just use MAP when i turbo my e34

[@TurbineResearch]

On megasquirt you just use speed density tuning. It only uses MAP , intake temperature and throttle position

[@SV867]

@@TurbineResearch thank you

[@jahmarigallimore8692]

Can u help me out ? Just finished my set up on my e28 similar set up to yours but running the pnp megasquirt 2 and could use some help with the tuning part.

[@TurbineResearch]

jahmari gallimore yeah, what part do you need help with ?

[@jahmarigallimore8692]

The base map on diy settings seem out of wack but the car starts. Engine size was set to 2000 cc. Could u send me a copy of your base map when you were on pump gas ?

[@TurbineResearch]

jahmari gallimore www.dropbox.com/s/mnpz7qo33802xca/91%20Octane%2012-3-17.msq?dl=0 here is the 91 tune. However, it probably won’t work unless you have the exact same setup as me. (Same ignition coils, same size fuel injectors, same sensors ) stuff like that

[@jahmarigallimore8692]

I kind of understand how to make the basic changes I just wanted something to compare too if that makes any sense lol

[@DanielLovelock]

Hey!! How's that e28 going now? Video please.

[@TurbineResearch]

Still running strong 💪 almost no issues

[@0809d5]

Why did you go with MicroSquirt instead of something like MS2/MS3?

[@TurbineResearch]

Nils Asejevs microsquirt is a few hundred dollars less that the ms2 or ms3 box. Microsquirt is ms2 software but just has a few less features. It does the job but for less money essentially

[@0809d5]

@@TurbineResearch Ah, I see. I opted for the MS2 kit and assembled it myself. Mainly because I wasn't sure if MicroSquirt offered everything I wanted for my build. I assembled it in about a week, which includes reading through all of the documentation, soldering, etc. I think I did good, seeing as I haven't done anything like that ever before. Can runs better than ever. No turbo yet though. What did you do in regards the exhaust manifold? Did you weld it yourself? How much did it cost? This is my biggest obstacle at the moment, since I don't have my own welding equipment (yet). I have a E34 535i which I intend to turbo for some low PSI boost (7-10?), just so I don't have to put in an aftermarket head gasket and studs, since those are really expensive. Also, how much did your injectors cost?

[@TurbineResearch]

Nils Asejevs good work man! I made the exhaust manifold from 1.5inch schedule 40 steam pipe from an industrial plumbing supply and a vibrant mild steel t3 flange off amazon. It literally cost me $50. I bought a welder for this project and made my way through with some help from friends. I just used the stock manifolds flipped up and just welded to the stock flanges. Yeah I’m on stock everything running 15psi (~350whp) for months now with no problems. Like literally never taken the valve cover off the motor and it’s fine and really fun. If you just want to have fun for very little money it’s very doable with this setup. Injectors are Siemens deka 80lb injectors from efisource.com probably $43 each

[@0809d5]

​@@TurbineResearch Noooo way. I was exactly thinking of just flipping the stock manifolds upside-down to avoid having to weld the whole 6 pipe flange. Thank a lot for the info! Hopefully I get my E34 boosted this summer. :)

[@0809d5]

@@TurbineResearch 2 years have gone by, and I have finally gotten my shitbox boosted. Thank you for your overview video again. It was a big help and motivation to get mine boosted. Here's my setup: kzbin.info/www/bejne/jX6sgGB9hLaMbMk

[@Robertgio]

Do you still have this? any issues?

[@TurbineResearch]

Check out my latest videos. Just made 560whp with the same car

[@CChan11]

I might have missed it but where’s the BOV?

[@TurbineResearch]

There isn't one. Just a surge ported compressor cover

[@CChan11]

@@TurbineResearch Interesting. how does it work? Is there a trade-off vs having a BOV?

[@TurbineResearch]

@@CChan11 it just pukes the extra air out of the compressor cover ports when you let off the throttle. It sounds the best IMO. BOVs just cause leaks In my experience. Not having one just reduces the chance of a boost leak

[@eddiesheeran5791]

Awesome build! I'm doing something really similar, I have an M30B35 in an E30 chassis, and it's getting an eBay GT3582. I want to see what it can do, and for how long!

[@TurbineResearch]

I am probably upgrading to a gt35 here soon as well. With a good tune these motors are really strong . I have been ruthlessly driving this on 15psi for 3 years and never had a single issue.

[@eddiesheeran5791]

@@TurbineResearch Great to hear! Are you using a stock head gasket and head bolts? I'm going to start with that. I've read the ARP studs do not fit well in the M30.

Why would you run "wasted spark" on individual coils? That makes no sense. 3 coils yes, 6 coils . . . . no.
