BMW E46 Turbo Build Detailed Build info

[@jsmoov27]

Where can i buy this kit?

[@OLearysBMW]

Go with Hopwood Motorsports or Be Racing Tuning kit if you can. The Cx Racing kit; the turbo manifolds crack, included gaskets and hoses are garbage. The Blow off valve is junk, same as wastegate. The turbo charger is hit or miss. May or may not last you a year Hopwood motorsports kits are track tested and include literally everything. Be Racing's kit is high quality as well. Don't go cheap with a turbo build. Buy a good kit or assemble your own. This video is two years old, back when I was new to DIY turbo things. Now that I'm more educated with experience. I would not use this kit long term. That being said, the CX racing kit is a decent budget solution for people looking to learn. But not for avid enthusiasts. In a nutshell, I'm giving CX Racing free advertising, as they refuse to reply to me. This is my most viewed video. The turbo kit price has gone up as well, as they're selling a bunch. Heck them.

[@OLearysBMW]

People who are viewing this video in 2024, this was my first ever turbo setup and second ever video of this car. I have learned a ton more, looking back I wish I knew as much as I do now. I feel I explained things fairly well for being an newbie, however. Now a days, the car is totally apart and is undergoing extensive modifications. I'm doing well and have my own little shop now. I'm still pumping out content for your viewing pleasure. The current build consists of an M52TUB28 that will remain NA with some modifications. I also have some M52B28 iron blocks that I'm looking to eventually build for boost in future. The later videos following the stock TUB25 turbo setup include details of the M52's and my current TUB28's. I have also gotten more comfortable on camera and have been uploading a decent amount lately. If you have questions regarding turbo setups for these cars, or other questions in general, I'm here. I appreciate all of my subscribers, you guys are like family. Thank You all for the support! -Tyler

[@OLearysBMW]

This engine is an M52tub25 but turbo process is identical to M54, 😁 only thing different is, your M54's stock fuel filter with built on regulator is boost ready (only recommend an 255 fuel pump max for stock FPR however) 👍 all other parts bolt directly onto M54.

Tyler O'Leary are you being honest? i can run my stock fuel pressure regulator?

[@OLearysBMW]

@@TheWindows360 Super late reply! I don't get notifications for every comment/reply. But, yes. The M54 fuel filter/regulator does in fact work with boost. Just be sure to stay within the fuel pressure tolerance I mentioned in my last reply to you. (Do not exceed a 255LPH pump with stock M54 regulator)

How has this car held up? I've got a 325i sedan I am manual swapping within the next week or so, looking to boost further down the line and this video is beyond helpful.

[@kungfuhustle6363]

Very nice clean set up. At 3 psi that's nothing for that engine and you have sensibly resolved any heating issues possible. it will last another 100k easily 👍🏾

[@OLearysBMW]

There's been some changes and new modifications, we're currently at 9 psi. 😁 Check out my newer videos if you'd like

[@anthonyk]

M50 Intake swap make more na power to help with the turbo

[@OLearysBMW]

Yes, a very popular mod. Since this video there's been a lot changes. With M50 intake manifold, you lose bottom end power but increases up top. I very reputable tuner has tested the M50 intake manifold and M54B30 stock manifold, and the B30 intake actually showed superior. I honestly think that was a boosted application as well. But if I'm wrong, it's NA and obvious as the M50 manifold I feel is better for boost. However, in high boost applications you'd want to source a different intake or have one built, as with high boost, the M50 intake concentrates air to only a select few runners, leaving un even distribution

[@micklee3995]

Superb video very helpful and informative. Quick question I have a similar set up on my 728 bmw it’s a m52tu but I keep getting icv fault coming up! Does your still use the icv and if so any issues with it?

[@cannon9359]

I’ll offer some advice on catch can system, be sure to get regulating valves vs a check valve on the intake side. I had a issue with to much vacuum causing one or two lifters to tick at idle. (Oil flow problems) Also I’d suggest getting the new vtt crankcase breather for when you go into boost releasing positive pressure. It works great for me.

[@OLearysBMW]

I have an open to atmosphere vent, haven't had any problems. I know running a sealed catch can system with boost on these cars can cause havoc. So I haven't messed with a sealed setup

[@cannon9359]

Yeah it does. That’s why I mentioned the VTT oil cap breather for turbod bmws, it seals at vacuum and releases positive pressure during throttle.

M54 engines with the FPR built on fuel filter are boost ready as they are however. I don't have links, but here's the injectors part number: 0280158123 ..as far as the pump, be sure to get a genuine, lots of fakes out there.

I'm not sure which DME version the 4 cylinder E46's have equipped. As we didn't receive them in the US. So I'd hate to give you the wrong answer. But I'm going to say yes, you will need the 6 cylinder's DME and wiring. You'll also need certain coding performed and maybe other harnesses.

Hello, I would potentially turbo your car, yes. I'm much more diverse now, with my own little shop. I currently have to service 3 other E46s. One is receiving a turbo build, other two are for subframe reinforcement. So my availability won't be immediate. $5,000+ for a turbocharger conversion. All the parts required, tuning, fabrication/labor, etc. Would be around there and plus some. Could be closer to $6k.

The BOV is fully tightened here, it never actuated. What you're hearing is compressor surge, once I let off the throttle, it shuts. The boost has to go somewhere, it's fed through the turbo backwards as the compressor wheel chops it up, giving it that flutter sound. You can really hear it in my exhaust video during the in-cabin footage.

The reliability of your car will be based on what components you've used and how conservative your tune will be. The car can last you a long time if built and tuned correctly. The biggest thing is to be sure the components you use are quality parts and will last. Before boosting the car, all maintenance must be up kept.

Online. Some fit better than others, check reviews. Also, I personally love the look of an Mtech 2 front on these cars. So maybe check them out as well

[@beefncheeseburrito1]

Do you know of this kit would fit on an m54 in my 2002 bmw 325ci?

[@OLearysBMW]

Yes, it does

[@Explocify]

I would love to do this to my 2005 BMW z4 which has the same 325i engine but mine is an automatic. How did you get the tranny to hold up

[@OLearysBMW]

@@Explocify swap for a manual.

[@anthonyk]

im looking to do this but worried about pulling the head studs

[@OLearysBMW]

You can boost the engine as is, they already have decent head bolts and an factory MLS gasket 👍 Just keep boost levels appropriate of course

[@OLearysBMW]

That little pop up is covering a street sign, lol. Only reason why it's there.

Hi mate..what is best engine for turbo...e46 330ci,328ci,325ci or e36 328i??? Many thanks

[@OLearysBMW]

My personal opinion is that the M52TUB28, found in the 328 series E46, is the best engine. Better harmonics than an M54B30, less oil usage due to better oil control rings versus the B30, but also still has an forged crankshaft along with cast iron sleeves like the B30.

[@OLearysBMW]

Second reply, the B28 in the E36 is another great choice. However, here in the US we have all iron block M52B28 E36's, minus Z3

[@khaledhamoud7836]

What about the AC hoses ? Did u have to take them off ?

[@carsonliming5585]

Did you have to pull the engine to put in the turbo or was it just a bolt on kit ?

[@OLearysBMW]

I installed the parts with the engine still in the car.

[@carsonliming5585]

@@OLearysBMW thanks brother definitely gonna pick up this kit was gonna swap but only have 156,000 miles and you have plenty more then me so I’m saying fuck it

[@OLearysBMW]

@@carsonliming5585 it makes the whole process easier to actually remove the engine, but up to you. Also, if I were to turbo an E46 again I'd buy the complete kit from Hopwood Motorsports, also known as FTWL Motorsports

[@carsonliming5585]

Sounds good how much hp were you pushing after the turbo kit

[@ichkackmirindiehoish]

Hi. Great job first. Where did you get the downpipe from? 

[@OLearysBMW]

Hello, it was included in the kit.

[@TheKeenMechanic]

Very good video and very well presented. You are very knowledgeable and I found the information very helpful. Thank you

[@OLearysBMW]

You're welcome. Thank you my friend, I've learned even more since this video. As the videos gets newer, there's more info.

[@TheKeenMechanic]

@@OLearysBMW Thank you, I might try and turbocharge my e39 530i M54 engine when I finish with my E38 project but I need to learn a lot more about the whole thing 1st as I have never done it before. Will be sticking arround. 😉

[@OLearysBMW]

@@TheKeenMechanic well, for the time being you can check out my other videos until I produce more 👍

[@TheKeenMechanic]

@@OLearysBMW Thank you

[@Soperflyguy]

Do you have to delete the AC on a turbo build like this?

[@OLearysBMW]

Yes, but people have better luck with retaining AC using a bottom mount turbo setup if that interests you.

[@deadshadow6798]

Can i buy ur engin..im looking m54turbo for my e46

[@OLearysBMW]

The engine here is an M52tub25, it's not for sale

[@micsmith806]

Im looking into this same setup and im curious how you run the o2 sensors. do you delete two sensors and just have the computer tuned to run off only one pre and post o2 for all 6 cylinders?

[@OLearysBMW]

The CX racing 2 1/2" downpipe has two bungs for upstream oxygen sensors. The factory downstreams are gone and mapped out from the DME. The 3" CX racing downpipe that connects to the 2 1/2" has one bung, I use that one for my AFR O2 sensor. Come tuning time, it's up to you if you wanna run a single upstream sensor, as your tuner can do that for you. Also good to keep in mind, is that the AFR oxygen sensor is recommended atleast ~36 inches away from turbo. A lot of people don't mind the distance but I followed the recommended instructions. Upstream sensors are also known as narrow bad, and downstream are known as wide band.

[@HipHopBeatSource]

Everyone I talked to told me don't turbo a 323i. You've given me the strength to take on the headache once I got the money to dump into it. Thanks

[@OLearysBMW]

You can turbo it, then when it comes time for engine replacement or rebuild all the parts will be ready.

[@placinta2192]

Search cody aplin on KZbin, he has turbo a 323i e46

[@brasscreations91]

I have a question about the coolant lines for your turbo. Any overheating issues so far ? Is this the correct way of cooling your turbo ? Is the feed line comming from the block and the return line goes into the lower radiator hose or is it the other way arround. Thank you . I am planning to use my e46 for drifting.

[@OLearysBMW]

This is an old video. But I remember how they're ran. Left side water fitting to coolant block drain, right side fitting to lower radiator hose.

[@brasscreations91]

@@OLearysBMW cool . Thank’s a lot.

[@natemyers3287]

What are the specs on the fuel pressure regulator?

[@cannon9359]

Hey did you get weird hesitation from 2.8k to 3.5k rpm from DISA ? Was wondering if that’s why you did what you did

[@OLearysBMW]

There was no weird hesitation. I'm deleting it entirely to avoid boost leaks in future, as they like to leak at an certain psi.

[@cannon9359]

Nvm just got a gep base tune, it’s no longer present

[@OLearysBMW]

@@cannon9359 awesome 👍👍

[@lucifr_-qu2sb]

You think it would fit nice on my 330i zhp ?

[@OLearysBMW]

Fitment is same for M52tu and M54 series engines. Yes, it will fit your 330 ZHP. Watch detailed build video part 2 to see what to watch out for for fitment issues however.

[@Darkaccent]

Did you have the DISA valve in here during this stage of the build?

[@OLearysBMW]

Yes and no. I used it to fill the hole and nothing more, I modified it, deleting the flap.

[@Darkaccent]

@@OLearysBMW Did you ever try using it when you had the turbo on or no? I've read it can possibly mess with tuning. Also have you gotten rid of the secondary air system?

[@Darkaccent]

@@OLearysBMW my bad I didn't watch the whole video before commenting. Lol

[@OLearysBMW]

@@Darkaccent never used DISA with boost. The SAP system is entirely gone.. It wouldn't fit with top mount. Also no longer have cats, rendering the SAP system useless.

[@OLearysBMW]

@@Darkaccent no worries man, but yeah if you're no longer including cats within your exhaust, the SAP no longer serves a purpose.
