The 135 is turbo at about 300hp & 300 ft/lb torque while the 128 is naturally aspirated around 230hp

Amazing explanation! The best video I’ve ever seen. Detailed oriented and very informative and simply explained. I’m amazed. You Sir are very smart and a great teacher

Happy to help!

@joepaquette7435 3 года назад

Nice Job, detailed and clean. So easy a computer illiterate old man can do it........up to the tuning portion. Lol one step at a time.

@kevinshasteen5682 Год назад

Thx for your E90/E80 wiring vids. You and others, but mostly you have lightened the burden of wiring the LS swaps into these chassis. This isnt a complaint but only a suggestion. If you wanna keep making these swaps and be ahead of the competition, how much have you thought about being the first to popularise the F30, F80, and G20 LS/LT swaps. These cars are not as cheap as the E90's yet, but their prices are coming down; especially those that are mechanically totalled.., something to think about ;)

@kevinshasteen5682 2 года назад

Great stuff. Thx for taking the time to make your videos! Now that I've been politically correct and mindful of your "feelings".., we need the A/C video and another FAQ video ;)

@lsxbeambeam5201 3 года назад

We need one for the 5 series that’s the one everyone wants

@lse90garage 3 года назад

What’s covered in the video is identical for the 5 series. We’ve mentioned that several times.

@Speedaholic69 6 месяцев назад

Sweet! Exactly what I was hoping for. Picked up a 07 525i wanna swap

@Bravadas10 3 года назад

Keep posting these videos. When you going to do an m3 engine mount kit.

@lse90garage 3 года назад

When someone gives us an M3 chassis to work with 😂

@frankhershman7253 2 года назад

stumbled on your video's while researching 335i swaps. Outstanding info, thank you. I've found a 2008 auto car with a bad motor but otherwise in terrific condition. Is using the stock BMW automatic over a T56 a good idea? I like the idea of reduced costs so I can put more money into a LS3.

@lse90garage 2 года назад

Stock bmw auto is trash, T56 far superior for the tq

@basscube5 Год назад

Hey! How are you triggering reverse in former automatic cars?

@2divinee431 2 года назад

Is the pin out different for a 2011 n55 e90?

@user-og5ri5rs7k 2 года назад

is it possible to retain the traction control?

@mrmeadowsiscool 3 года назад

Is this a 128 or 135? Is there differences with the two?

@ekytuning4449 2 года назад

hey, [USERNAME] Nice video! 🤩

@DickHamm 3 года назад

First 🥰

@reetrarker9556 3 года назад

Do you have a build thread for the 1 series? Like the trans/motor combo and if you used the stock diff. Thanks again!

@lse90garage 3 года назад

We’ll be going over the build specs as we do more videos on the 1, but currently it’s a stock diff, stock bottom end 6.0, with a built 4l80e and circle d converter

@ThaHammieJaassee 10 месяцев назад

how do we wire the pt can wires to your box if we're using the stock 5.3 ecu?

@lse90garage 10 месяцев назад

You don’t, the CAN box is for use with Holley only, currently is nothing available if you’re using a stock PCM.

@stephenj6139 5 месяцев назад

Love the video(s)! Where does the green wire on the main harness go? And for an auto does pin one (blue/black) need tied into the brake light(blue/red) /gray tran wire? And also for the automatic do the red and blue/red need to be connected to red and blue/red for tran can? I didn’t see that in the video but it’s on the website, maybe I missed it.

@lse90garage 5 месяцев назад

We have found it's better to use the 3rd brake light wire out of the frm for the transmission grey wire. Green wire on the main harness can be used to trigger a fuel pump relay if your rewire/delete the ekp

@stephenj6139 5 месяцев назад

Bro with the quick response! So green can be unused if I’m running n/an and stock pumps? And gray tran to Blue/red like the video shows? What about the red/blue to red/blue pt can? I’m close to done wiring but feel stuck/confused

@lse90garage 5 месяцев назад

@@stephenj6139 red and blue or can pair to the can box wiring. Don't use the blue red for the grey brake wire. It causes issues. Use the 3rd brake light wire out of the frm

@resinductelec Месяц назад

I did this proceedure today. Three of the wires going by the color were off by one number where it was pinned. I chose to go by the color rather than the pin location. I hope that is right.

@lse90garage Месяц назад

What’s your year and model? There have been instances where some chassis have things slightly diff but typically if you stick with the colors you should be ok.

@hectormagana6622 3 года назад

Those this all work with the 135i n55 engine ?

@lse90garage 3 года назад

The n55 wiring is slightly different but yes it will work

@omarsyr3963 Месяц назад

What about the E60 5 Series? Has it been worked on before?

@lse90garage Месяц назад

We have completed one, the wiring is very similar.

@SFGPUMP Год назад

Does it have to be the 6.0ls? Or could I use a 5.3?

@lse90garage Год назад

Any LS works, 4.8, 5.3, 5.7, 6.0, 6.2, LS7, LS9, 454 LSX, C5R block, dart block, doesn’t matter, they’re all the same physically.

@RickyLefleur 3 года назад

Do you have to use a Holley setup or could you use a factory ecu setup

@lse90garage 3 года назад

If you want to just run the engine you could, but you’ll have no way to configure anything to work with the BMW chassis like factory, plus by the time you spend the hours to modify the stock harness, buy a wideband, buy a boost controller if you’re going boosted, buy hp tuners so you can log it and make adjustments, and then pay for a tune, you could have just bought the Holley like we tell you to.

@RickyLefleur 3 года назад

@@lse90garage I was talking about a simple DBW/auto harness. And it would be for a N/a build. Also have all the access to hp tuners. The harness seems to come off with all the same lead/unterminated wires.

@lse90garage 3 года назад

@@RickyLefleur as we said above, you can do it, but the car won’t know it’s there and you’ll have no gauge setup or a/c control.
