BIG BOOST EXPERIENCE | WHAT TO EXPECT | SUPPORTING PARTS NEEDED N55 F30 600+ WHP

[@eightsix3700]

FACTS...100% true. I got my kit almost 2 years ago and Juan claimed I was one who had an early kit. The intake, oil line, downpipe, and a few bits and pieces didn’t fit. The wastegate was faulty too. He doesn’t have a turbo specifically for external wastegates, you have to modify the internal wastegate on the turbo by welding the flap shut. It looks horrible and hopefully it doesn’t leak down the road. I also had to shell out money to get this working correctly. The water line is too large in diameter and he supplies the worm gear clamps rather than T-bolts, and mine still leaks. I have an external WG and the dump pipe points right at my plastic transmission pan so I had to get a shield custom made. BTW it took almost 2 months to receive everything, and he even argued with me because I was upset that the parts didn’t come in the timeframe he stated. Just as you stated, make sure you book shop time for install AFTER you receive the parts. I lost a lot of money booking on what I thought was my time, but it was really on his time! Basically used leave for no reason when parts didn’t show up, and paid the shop extra because half the kit didn’t even fit.

[@BOO5Tchannel]

Unfortunately have people hitting me up on Instagram that just bought kit with similar experience, if he fixed the issues and was a bit more honest he could be more successful.

I have literally the same spec F30 and your build is an inspiration man! Want to go speed tech soo bad but I know where’s a rabbit hole of other things I need to do.. hopefully one day!

Thanks Chris this was great info. I recently purchased a used stock 235i with low mileage and I've been slowly buying parts. I think after hearing all that you said, I'm gonna have to be satisfied with the pure stage 2. I think I'll be getting in over my head with the big turbo 3.3 or 3.4. Thanks again for the video, good stuff. Best of luck to you.

dropped off the f30 at my mechanics shop the other day. Engine is toast he says..a brand new engine from BMW is definitely not the move and a used one..definitely not. should I go with full built engine? a fully ported head and everything? Would run about 15k but I believe a brand new n55 will run me more than that.

Quick question. Just ordered the 3.4 kit for my 2016 M235i (F23 N55). Would the extra parts you listed be generally the same that are needed?

[@BOO5Tchannel]

Hard t say but possibly, sorry for late response I just saw this comment.

[@VictorEstrada]

I'm so glad I went with SpeedTech npw that I see this video, just dropped it off at the shop the other day, getting installed this week. I also saw that replacing the LPFP motor/pump with a 535 is far more than enough, since it's rated for like 60psi turbos and/or 900hp. Than Also saw that upgrading just the HPFP would do the trick for 650whp and tuning wpuld be a whole lot easier. My question is though, can I drive my car around with the stock tune and fueling and the EFR 8374 kit for a while at low power, say 20psi, until I do the fueling upgrades and custom tune?

[@BOO5Tchannel]

I would say get your base tune ASAP I wouldn’t drive it on current tune

[@kimmyphan434]

I just ordered the 3.4 kit about two weeks ago with the ball bearing upgrade and I really hope it doesn’t take as long as 7 weeks as everyone else has mentioned.

How long have you been building your car and do you know and understand how to fix things here and there? Also how much psi can you push the factory turbo before getting a pure stage turbo for an N55?

[@BOO5Tchannel]

Hello, i’ve just reached the year of the build of my car and yes I understand how to fix things especially when you do your own work like I did. I’m not sure how far to push the factory turbo but I wouldn’t go that route I will just go to a pure stage two. Factory turbo is a tiny Borg Warner it’s not meant for more than it’s pushing

[@S58PSHIFTING]

@@BOO5Tchannel Yea no i agree 100%, the Borg Warner is so in my plans, im already ordering parts, and want to keep it simple at at least 450hp give or take, im satisfied with that, i rape people as it is with the power it has, i can only imagine having a 100plus more, thanks for your answer.

Did possible make to i535? Still search to buy..some one selling year 2013 did is good year range? Did need also some M kit? How be if uprage twin turbo to some medium turbo like size td05 +-

Do you feel like the VTA design of the bigboost turbo changes or reduces the DV sound? I recently put in a GFB DV+ and it became almost silent, and in looking into it I realized the bigboost DV setup seems quite different than PS2 and stock - big boost seems to be the only one that has the open air vent on the pipe right below the DV housing Separately, I have had an absolutely horrible time with juan/bigboost (and continue to hear the same from others) - when my banjo bolts failed it was a nightmare getting a replacement from him. The provided worm clamps failed eventually too - getting all those replaced with T clamps was not cheap just due to the time to get to all of them.

[@BOO5Tchannel]

Yes I hear same things and BB is the cheap route which is not always the best one. I went custom bov most of the BB design is cheap not necessarily functional.

I got the 3.3 kit and my guy installed it in 2-3 days(My HPFP got Lost thru delivery so that’s why he took 3 days max but he would of had it done in one day damn near he’s crazy ). The first day he already had the kit partial in . He didn’t need instructions he did say the kit wasn’t one of the best kits he has installed but he did say he had to trim some stuff other then that the only thing did come lose was the pipe to the intercooler from the passenger side . The clamps are cheap I pulled up to my guys house n he had to use a diff clamp he had extra . The clip that held the pipe to the intercooler wouldn’t lock in for some reason the driver side was nice and tight but other side it would just pop out so he hammered it in but other then that it’s n ok kit . 6 months going n still good . Still on base tune because bootmod is stupid and my flashing stopped working after they did updates and they had to manually flash my car back to stock they said “nuke” my account so lose everything and would have to message tuners again . Anyways that lasted since like January till March when they released a new update which I didn’t know and just a day ago for some reason I decided to flash my car because I saw my app updated by itself and flashing worked again . Base tune by wedgeperformance. Anyways kit is ok just depends who gets what parts some people get lucky some don’t . Now when I log and get a better tune i hope pipes don’t go blowing off lol . My guy also said that T clamps is the way to go with the kit better and save you the hassle

@@BigBoostediF what's your intake and bov/DV setup, and how does it sound?

My answer to all this is stay away from big boost. I still get horror stories and if you want to risk your car and your wallet go for it. The N55 can handle around 600 before you have problems. I don’t even know what you mean by wooshing sound… go to a pure stage 2 to make sure you don’t have issues.
