That sucks man i hope u get your frs fixed I was in that boat I ended up buying another e90 with a bad oil pan leak i got dirt cheap just to daily because the r&d on this car actually took years I’ve been at this 3 years now changing the setup adding things overcoming issues for more power gains and I hardly got drive time out of it but was constantly working on it. But that same n/a e90 just took all kinds of abuse and loved it I use to slide the n/a e90 every time I drove it so even without boost these cars are sick af 👍

@rumrunnersracing they're definitely fun af NA. I ended up having the crankhub spin on mine on Tuesday but got it retimed and its better than it has in a while. Definitely a platform that's deserving all the revent r&d

Last setup I made a bit over 600whp on the dyno but we had to back it off due to intake temp issues so it sat around 480whp we’re going to shoot for over 600 on the hub dyno to make it one of the highest hp n52 motors around

@@jeffthekiller6648 in this video they’re completely stock I didn’t open this engine just added the turbo and fueling mods with a standalone ecu.

@@rumrunnersracing be cool to see more experiments done 👀 like n54 rods used and maybe see if the closed deck conversion fits the n52 block as well

@ I was going to upgrade rods but they are forged from factory so if they fail then I’ll swap in the next build the main thing this build has going is it’s the only one to use boost and valvetronic functionality the n54 dosent do that. If I ever get sponsored I will definitely be willing to experiment more with these bmw platforms 👨‍🔬 🧪 closed deck and getting steel sleeves with water methanol injection and aftermarket head studs it would make big power I have a ported head I’m working on as well that’s going to be put in next season after I dyno it and see what gains it gives me.

When you see the video where I show the damage Its crazy it started at all and I was able to drive it into my barn I’m surprised it didn’t lock up the cyl6 was missing like 20% of the bottom of the piston. This is engine #2 that this happened to running 14psi so I did an overhaul on engine #3

Yea it’s was piston #6 ring land let go since this video I’ve rebuilt the engine with new low compression pistons and gapped the rings to 0.023 so it’s ready to see 18-20psi but my clutch slave cylinder quit on me so that’s my newest issue 😅

@@Builds23 I’m shiftin like a samari 🥷 😆

@@Elbmwenthusiast there’s no set spec for gapping rings u do it for how much boost you plan on running you only need one tool the piston ring grinding unit my buddy used in the video and we recommend doing 5 rotations then measure then another 5 it’s better to go slow because if you take to much material off there’s no going back. Both top rings get gapped and the oil ring at the bottom gets left alone I shot for 0.023 stock was 0.013 you could just go for that. How much boost do you plan on running with your setup?

@@rumrunnersracing OK I’ll go off base with the recommendation that you gave me cause I’m trying to aim for at least 19 psi if possibility, but you’re already doing all the things ahead of me what I’m doing because I’m already rebuilding my engine as well with the n52 that already has 150 K mileage I’m learning from you because halfway through I’m already buying all the parts to throw a turbo on it

Glad I could help pave the way but I would start lower boost and work your way up I would thrash it at 10-12psi work out the kinks of the build if there is any then work your way up. Also tuning is key when running high boost you will not be able to rely on any remote tunes or anything you get online you will want real time tuning or the motor will just blow the head off. That being said the one thing I didn’t address is how strong stock head studs are will they be able to handle 18-20psi I’m not sure 🤔 but to help the situation I will be adding water methanol injection to keep intake temps down that’s another crucial part of the setup hot intake temps and high boost will also blow the engine. What is your plan for tuning?

@@rumrunnersracing my plan was going to Stage FP for tuning for turbo. I also was looking into 22 RPD which I heard from both parties they are good but as you said, I think remote tuning is not as good for turbo because yeah you might end up blowing a head gasket so what I’m going to do is an ECU exchange or buy an AEM ECU for a piggyback just in case or just ship my car all the way out there lol but I heard stories about they’re tuning capabilities with turbo and superchargers and they are pretty good and as well as 22 RPD, but yeah as you said, let me start off low first start before I go high

@@Elbmwenthusiast nice man sounds sick also you will have to lock your valvetronic at whatever height you want to run because other standalones or piggyback ecus wont have the ability to control valvetronic that’s y my car made such good power my ecu is custom made by my tuner to use full valvetronic function with boost you man be able to snag one of the first ones my tuner is finalizing it over this winter before he makes a run of them. He’s just working on all the automatic functions because testing was all done on my car and i converted this car to manual almost immediately after I got it. My tuners website is www.popformance.com he’s a Tuning wizard and makes ecus and all sorts of stuff you could inquire about tuning and the standalone development thro his website his names Patrick tell him Matt with the e90 gave u the info 👍. Ide love to see progress pics do u have any Instagram or anything?

Got that long throw 😆 but she bangs the gears pretty good I’m not a fan of short throw shifters it’s to much travel from the shifter to the hydro e brake. This way u swap back and forth easily.

@@thecrazyy2O4 I don’t get the question lol any n/a car can be turbocharged Ls motors never came turbo but boosting them is the easiest way to make massive power. It is a hassle that’s for sure but if your a car guy hassle is just part of the game. You could run low boost and be fine but I test the limits and slowly upped the boost until something broke and now I’ve rebuilt the engine to overcome the issues that stopped me from going higher then 14psi but with the time and money I put in personally it’s not worth it but I pave the way for other people to be able to boost and know what Theyr getting into then they can decide if it’s worth it and for most ppl It’s not 🤷‍♂️ but for a select few die hard car guys it is 💪😎 built not bought isint for everyone lol

@@thebestsoccer2063 my tuner Patrick at popformance made the standalone I run and he does all my tuning the standalones he’s making are plug and play for the n52 and it keeps valvetronic functionality with boost its a game changer for the n52’s he can be reached at www.popformance.com if you wanted to reach out about tuning or getting a standalone he tunes cars for a living so if your in Canada it’s worth it to get your car tuned by him.

@@abiellewis7307 I have a dyno sheet where this setup made a bit over 600whp on a hub dyno but 💯 I’ll be posting numbers and dyno videos.

I assume he’s using water/methanol injection setup for cooling and fueling also if he runs e85 it’s a lot easier to hit that 500 my setup is tuned on 91 pump gas with no methanol even a basic setup with meth keeps cylinder temps so much cooler and avoids the piston rings from touching so you can run more boost and more timing safer on e85 with methanol ill be adding meth to my setup but the kits expensive so It won’t be right away I’m going to see how much power I can make without it on 91 pump gas and this massive front mount intercooler and my ported headlight intake it keeps intake temps a lot cooler then taking air from the engine bay.

@@jeffthekiller6648 no Theyr piston rings this is how you open the gap on piston rings to be able to run more boost like a car that’s turbo from factory

@@rumrunnersracing my bad bro I was asking if you sleeved the block lol, phone wasn't rendering the video great 💀

@@jeffthekiller6648 nope the block is all stock still haven’t found the limitations on the block itself the main issue is these cars will break piston ring lands when you push it over 10psi due to such a tight ring gap from factory. The added heat from boosting over 7-10psi is enough to blow it especially how I drive the car 😆 Ill have to check with a magnet tonight in the spare block to see if it’s sleeved but I’m pretty sure it’s an aluminum sleeve in an magnesium block coated with anti friction coating

@@rumrunnersracing go check out one of the forum's on someone pushing 600 HP on the stock internals. Pretty sure the wristpin is a weak point on the rods as well.

@@jeffthekiller6648 yea I’ve made 600 I’ve just never blown a wrist pin it’s usually bottom of the piston chunks off also not many ppl gap the the rings for boost so the higher compression with boost would expand the rings they touch and blow the wrist pin my car had headlight intake and the biggest intercooler I could buy so my intake temps and fueling were perfect my issue was the compression ratios which in this build I brought down pretty significantly and running valvetronic will give me the added power no one else could get because my standalone was custom made to support valvetronic it’s something my tuner is developing it’s pretty sweet

@@SV867 that’s a hard one it’s a purpose built drift car so u less I do a roll in third gear shes spinnin 😆 I just got my motor moved to the barn so the car will be back in action with a rebuild for more boost I’ll make sure to do some highway pulls and get more daily driving footage.

@@rumrunnersracing big inspiration for my n52, I can't decide between a turbo or supercharger setup. It's a daily so I need it to hold for a while. How much was yours putting down?

@@SV867 around 480whp if I had to guess we hit 600whp on the dyno but had to back it off the valvetronic hit to hard it made 600@4500rpm and made 600ftlbs of torque and that was to low in the rpm to make that much torque

@@rumrunnersracing those numbers are nuts.. once you get your rebuild sorted you should be able to safely reach that torque at lower rpm. Good luck I'll be following for results 💯

@@naird1064 I have a few videos on my channel in what you need to to for low boost on a stock motor without doing any internal work. I’ve also got a build where I open the motor and swap lower compression pistons into it and gap the piston rings to run more boost if you want to check it out the first video is what you need to get started. These motors are fine for 7psi with good fueling and a tune it really wakes the car up on so many levels.

How many hp should i have with 7psi of boost

@@naird1064 you would be in the 300 whp area maybe a bit better it really depends on tuning how aggressive the timing is and how good your fueling is like if you run e85 you can get more aggressive timing without knock so you can make more power on 7psi then someone restricted to 91 octane pump gas but regardless low end you should sit low to mid 300’s tune depending

Yup that trans is stout af it’s handled all Kinda of abuse including testing launch control where I bent both sections of driveshaft and sheared the teeth out of my diff and tore 4 of 6 bolts out of my guibo 😅 but the trans was fine tho and I slam gears all the time with it.

No the trans is still going strong that was me missing 4th hard 😆 that is fully stock compression never opened this motor at all just supporting mods and good tuning and fueling but they are high compression motors so I pulled it and am currently swapping to low compression pistons that will taken it to 9:3:1 from 10:7:1 and I’m falling the piston rings because stick ring gap on these cars is really tight

@@rumrunnersracingso say you had an N51 with lower compression. Would you still need to swap pistons to run that boost?

@@Serqz no the main thing is not falling piston rings when you boost the car. Also boosted cars like lower compression I added the low compression pistons so I could go more then 14psi and add timing and it makes the whole setup safer so I can thrash on it this is a drift car I’m going to compete with. N51 I believe runs Lower compression from factory. Also I never mention it but in these videos my exhaust manifold cracked in 3 of 6 exhaust ports so this is the slowest the car ran.

@@Serqz you will still want to open up on the ring gap if you wanna hang out around 14psi or you will likely blow a piston ring land I’ve done it twice so far before I checked stock ring gap on n52 it’s real small like 0.011-0.013 I gapped mine to 0.023 so I can shoot for 18-20psi

I wanna try to shoot for a semi reliable 600whp the cars made that power before on the dyno but we had to stunt the tune a bit due to intake air temps it would be heat soaked by the second run and start to pull timing so this time around I’ve made ALOT of changes to squeeze out some extra power

with proper fueling and a rising rate fuel pressure regulator and a tune it will run 7psi all day on the stock motor without opening the motor to gap piston rings, You could thrash on it all day and you would be fine at 7psi when you get 10-12psi your in the yellow area where u want to open the motor and gap the piston rings for the added boost and you want great cooling for intake air temps and dissa flap will snap off at this pressure inside the intake manifold so it needs to be deleted if you wanna run 10-12psi
