Burger Motorsports has the following kit on for $1500. Does anyone have personal experience with this combo? Is it a decent way to start modding my '08 335xi for some light track use and spirited road and highway driving? Bang for buck is it a good deal? I am COMPLETELY STOCK at this point with the exception of B6 shocks and struts. The car is a toy, not a DD.

Here is the kit:

BMW 3 Series
JB4® 500 Horsepower N54 Package w/Stage 1 Fuel Pump
Save $295.00 when you purchase this package together.
Kit Includes
JB4 Performance Tuner

JB4 Mobile Connect Kit

BMS Chargepipe with authentic Tial Blow Off Valve

BMS Dual Cone Intake (Red Filters)

BMS Replacement High Performance Intercooler

Fuel-IT Stage 1 Fuel Pump Upgrade

NGK 2STEP Colder Plug Change Kit with BMS Gapping Tool & Socket

Burger Motorsports "JB4 Tuned" License Plate Frame

White Burger Motorsports Logo Sticker Sheet (2 Pack)

Official JB4® Logo Car Emblem/Badge

JB4 Magnetic Cell Phone Mount


TIA for your impressions and advice.

I would go the mhd route and purchase the parts separately i think all in i was about $1100 to go full bolt on.

Has maintenance been taken care of first? Can get expensive if not especially stuff like injectors run $1300 alone

I'm pretty much up to date with maintenance, just transmission fluid and filter and transfer case fluid to change out. My injectors are index 8 and I know they'll have to be upgraded but that's a "must do' regardless of which way I go. New spark plugs will come with the JB4 kit.
Do you remember what items you started with? Looking at your list, excepting brakes and wheels, I don't think you can get all that for $1100. Just doing a quick search and I'm already over $1400 for a VSFR FMIC & charge pipe, MHD and WIFI connector, Vader fuel pump and DCI. I haven't added in spark plugs, DP or BOV yet. I haven't been searching around for the best deals on these items but I doubt there will be a huge difference from one shop to another.

I came in right at $1000 for downpipes, intercooler, chargepipe, BOV, cone filters, DIY stage 2 pump with MHD and the necessary cables (no WiFi for me). I'm also not afraid to use eBay for certain things . Regardless, with that JB4 package you'd still need to get downpipes on top of the $1500 price tag. I think most here are going to steer you toward MHD. IMHO it's the better choice.

[Smgs1992]

First are you planning to run E85? If not the lpfp isnt necessary. As far as fbo is concerned i was talking about dci downpipes intercooler chargepipe and tune.
Again going back to E85 if you arent gonna run it and your plugs arent that old youll be fine on the stock plugs.
I am using the stock diverter valves if you plan to run a bov that may drive the cost up a little bit

$79 dci
$299 downpipes
$450 intercooler
$150 chargepipe
So $1200 my mistake for the parts and MHD tune. However you do not have to go with as large an intercooler as i did which would save you some money. Depends what your end goals are

I'm not planning on going e85. It's not available here. The intercooler that I looked at was $400. As for my goals, I'd love to see 500whp but I realize that's going to be pretty tough to do on 91 octane no matter how much money I throw at it. In reality I want to get to the next light first... every fucking time! Seriously though, I am a VERY aggressive driver and I hate following other vehicles. I figure if they are behind me then I don't have to worry about their stupid driving. I also like the sleeper idea so I don't want loud burbles, pops and crackling. I also plan to go to the odd track day at my local track, a 1.6m road course.

Yeh stick with MHD.

That JB4 kit is a joke. $1500 for a load of stickers and some hot air intakes, no thanks.

You wont see 500whp unless you upgrade your turbos
If you arent running E85 and are gonna stick with the stock turbos atleast

If you drive like that everywhere once your tuned i could see you losing your license quick...just a warning to be careful

I've always wondered how they can advertise those JB4 kits as making 500hp.....when they don't.

You are betting off to just buy DP's, FMIC, stage 2 LPFP...and MHD. Might get you 450-ish to the tires if you run the stage2+ tune with e40-e60.

All the advice is contingent that you have done the laundry list of maintenance prior to going FBO, otherwise expect problems

My guess is that they can on a new motor. If I remember correctly guys were dynoing stock cars and making 300 whp (sometimes a tad more), so the motor is underrated from the factory. With just the jb4 netting an extra 100hp (say 85 to the wheels), those mods only need to get you about an extra 40hp to break the 500hp mark.

So I think it's technically accurate, but not true that you would make an additional 200hp, more like 150-160

[Vulcan50]

Clarification:

They advertise 500hp "possible" not 200hp gains.

Actually the word "possible" does not show up in the description anywhere that I saw.

I remember 270whp dyno runs, which would still point to an underrated motor, but 300whp would be crazy. You have a link to that claim?

HAHA, I drive like that with my '17 Sierra 2500hd crew cab with an 8' box. It's a lot easier with the E90 because you don't need NEAR as big of a gap in traffic to jump lanes. My truck is nearly 23' long with the step trailer hitch installed.

I knew the gains with the JB4 kit were... "optimistic" when I saw the add. I'm just looking for the kind of input from more experienced enthusiasts that I am, indeed, getting from you guys right now. The consensus seems to be to forget about the JB4 in favour of MHD and buying parts individually. All relevant comments are being noted and considered.

At the bottom of the ad BurgerMS replies to a couple of less-than-favourable reviews. Here is one of their responses:

We've gotten over 500whp (Dynojet) on factory turbos with several customer N54s. Email in JB4 datalogs if you'd like us to help you evaluate your cars tuning and ensure you're getting as much a you safely can from it! Tuning advice is a free service provided to all JB4 customers.

- Burger Motorsports, Inc.

So apparently they think it is possible. I am still skeptical. I know I won't be able to get 500whp simply because the best fuel I can get here is 91 octane. Doesn't stop me dreaming though. In reality I would be happy with 400whp as a gateway drug to more power. The consensus seems to be MHD and buy parts individually. That's the information I am looking for in this thread.
Thanks for your response.

Yeah the stickers and other JB4 propaganda shit are of zero interest to me. I like to be the sleeper in the line of traffic. I'm just looking for opinions about the JB4 system and the value of this package. I thank you for your honest, if not blunt, response.

[stewbets]

Oh wow, I just assumed they meant 500hp at the crank, which can mean as little as 400whp. But 500whp out of this kit is just plain silly.

[iqraceworks]

The majority of people with MHD, FMIC, DCI, LPFP, and DP's are getting around 440-460hp at the tires on an ethanol mix type stage 2+ tune on stock turbos. I have yet to see a Dyno sheet showing 500hp or more with that combination of "bolt on" parts.

Is it possible?? Maybe if you mess around with the Dyno calibration 😁

So am I being unrealistically optimistic to get 400whp on 91 octane? 91 is the best fuel available here. What whp can I expect to get with MHD, FMIC, DCI, LPFP and DPs?

380-ish hp at the tires should be doable on 91oct. Don't think you will hit 400hp without 93....and even that might be tough.

Can you give me your laundry list so I check to see what I may have missed? I think I'm pretty well set but I have no first-hand experience with turbo system mods. I've done my share of drag racing but that was a long time ago and we ran NA big-block Dodges and Chryslers. Oh and no computers.
