Well, engines are big air pumps at the end of the day, my N54 is no different. When we try to cram all that extra air and boost into the engine, you need enough fueling to support the increase in pressure.
We quickly found the shortfalls of our e82 BMW 135i's fuel system, the factory fuel pump was tired and not up to the task. In this episode, we revamp the fuel system to give it a new life and hopefully help us free those beastly German ponies, pushing us closer to our goal!
Stay tuned and watch how we complete this DIY!

Absolutely wild build! Don't forget to eventually upgrade your ekp module if you're running an upgraded fp!

@ZaksWorld14 3 месяца назад

We bought a bunch of upgraded ekp’s don’t worry he’s got one! 😂

@tony.nextlevelrides 3 месяца назад

the stock EKP only lasted one pull before it quit. 😅 the upgraded one is working great.

@@tony.nextlevelrides oof 😅Good thing you were prepared! have you had any issues after drilling out the rails? I wanna do the same on my 135 cause I don’t wanna run PI just yet

@tony.nextlevelrides 3 месяца назад

@DITLEOT nope! ZERO issues. *knock on wood* if you drill it, don't get too greedy. a tiny bit bigger is fine. just make sure you use GOOD bits so they don't snap.

I want to push my 128i but have now idea how to do anything to it. How do i find someone that does and will do what i need? Like how tf do so many of you do this like you have every inch of every car memeorized. I camt remember 1 number when asked to

@joshuaquilliam2887 3 месяца назад

Just read forums and fix your own shit bro. 6 years ago I couldn't tell you what a turbo was. Now I build my own motors both diesels and gas. I have built my own transmission as well the 48re in my truck. I have an awd N54 E90 and I just did my rod bearings, oil pan gasket, pure stage 2 turbos with inlets. I did it in my garage on jack stands. Car runs great! It's literally just nuts and bolts. Take your time, have the necessary tools and dig in.

@ferminperez1643 3 месяца назад

Word of advice don’t push your 128i… get a 135i with an n55 or n54. Will save you some money and trouble.

@tony.nextlevelrides 3 месяца назад

years and years of practice. I slowly started 25 years ago.

128?!?!

@kylerowden4777 3 месяца назад

get a 135i and get a tune that’s abt it

To what psi fuel pressure was dropping to? Also how much E85 can the stock fuel pump handle before it dips on pressure, also what was the ambient temperature versus the iat temperature. I know at least for my car, it performs better on ethanol when is above 70 farenheigth. Very interesting at least to me. Also you running a flex fuel kit? Or is on pump gas all the time? Nice car too that body is very desirable?

@tony.nextlevelrides 3 месяца назад

we covered the fuel pressure in the video, it was dropping to around 51psi before we let off. dropped quick. outside temp was around 12-15c. for ethanol, I wouldn't go much past e20 on stock pump. it'll be pump 93 until around 20psi and an ethanol blend on the "aggressive" map.

@098cpt 3 месяца назад

Coincidence, did this mod last weekend. I use the same 450 pump, but kept the venturi and kept the bucket. It fits. I did active cooling on the EKP, did a small how to on e90post. btw the sock can block your float.

@tony.nextlevelrides 3 месяца назад

awesome! feel free to share the link! the strainer we used was pretty ridgid otherwise I'd have bent it up like the stock one and not cut the bucket.

@edwardwerley8831 3 месяца назад

Tony how is the 8HP45 handling the power? I have the 8HP45 also and Ken from CANtcu was saying about 650-700whp the 8HP45 starts to hit its limits. What are you hear?

@tony.nextlevelrides 3 месяца назад

it's been fine thus far! doubt I'll have issue around 650whp. only issue is if you're digging all the time.

Are you going to be doing the direct injection delete?

@tony.nextlevelrides 3 месяца назад

nope, just port injection to supplement and take the strain off the direct injection. you can't beat the Drivability of the DI system.

@joshuaquilliam2887 3 месяца назад

Glad I'm not the only one that avoids looking at my cost haha.

@tony.nextlevelrides 3 месяца назад

it puts things into perspective that I'd like to remain oblivious about. 😅

@GamerFit86 3 месяца назад

man at this point it's not even a 135i anymore! I don't recognize her lol

@tony.nextlevelrides 3 месяца назад

it's still the same car just with a new heart! we'll have to do a video of you driving it when she's done-done.

Hey hows it going, love your e82 its extremely clean, I currently have a fbo e92 n54 with the 6hp auto in my car, I have recently ordered a docrace top mount 6266 BB kit, and its getting delivered in a few days, i have been looking into the 8hp swap, and my goal is to be around 700HP, To make it easy i wont ask any questions, but if possible could you send me a list of things i would need for the swap, and how many hours of labor it would take me to install, i work at a shop with lifts and all tools needed, thanks please let me know - Parts list, and labor hours

@tony.nextlevelrides 3 месяца назад

I'd say total you could be into it for 10-15hrs, if you got an 8hp45 it's pretty seamless and straight forward. just need the cantcu stuff, transmission cooler adapter and an N55 torque converter. that's pretty well it.
