Stage 3 LPFP Upgrade for BMW N54! | DIY Install

Stage 3 LPFP Upgrade for BMW N54! | DIY Install

I got the Dual Walboro 450 LPFP set up installed and the car is 1 step closer to driving! This should provide plenty of fueling for upwards of 700+ WHP even on full e85. Looking forward to testing it!

For anyone wondering, I am having Ken from Wedge Tuning custom tune the car. Im gonna be running an e40 map on DI only, so should make around 550-570WHP when its dialed in, then going for 700whp in the spring with Port injection and full e85. This thing is so close to being ready to rip!

Are you getting an lsd at all? Haven't seen anyone replacing the diff with an e9x m3 diff on the 1 series. Budget bimmer did it on the 335i.

I love what you are doing with this car Neiman. But just some constructive criticism here…..Your doing so much and so good on this build. Why not run the wires through the center of the cap instead of pinching them? I'd hate to see something go wrong because they were pinched. I could be totally wrong about that and maybe nothing will happen. I do understand your thoughts on it though but i think i have to agree with Ronald Wright. It's your car and it's your choice to do what you wish. Can't wait to see the tires smoking!

I about ready to crank (Start) my new rebuilt engine. If you remember my last comment my rod bearing blew my engine. I found the main reason. When I took my engine apart cylinder 4 & 2 where running lean (low fuel, more air). My intake valves above cylinder 4 was Extremely white due to extreme heat because the fuel didn’t cool the valves and the piston. The heat eventually heated the piston which then caused friction between the rod bearing and Crankshaft when there’s friction then the rod bearing will scratch your Crankshaft which causes improper lubrication. My bearing was crushed and damaged my Crankshaft which costed me over $1500 for a new one. Also my intake ports were very dirty with carbon buildup. I talked with a tuner who seen many N54 engines with rod bearing getting crushed cause of improper fueling. He said Stock Hpfp can’t pump enough fuel into the engine, they can do well with anything below 400whp. My car unfortunately either the hpfp or fuel injectors were not operating as they should and cause this huge problem. Luckily my dad owns a mechanic shop which labor is free and parts a discounted prices. But everything still costed me over $4000. Now my engine is brand new and I can’t wait to start my engine on Monday.

PLEASE MAKE A VIDEO ABOUT THIS PROBLEM. TELL PEOPLE WHEN BUYING A N54 TO CHANGE THE HPFP AND FUEL INJECTORS IF THEY ARE PLANNING TO TUNE THE CAR. PLUS TO CLEAN THE INTAKE PORTS. IF THE ENGINE IS RUNNING LEAN IT WILL CAUSE THIS PROBLEM. I HAVE NOT SEEN PEOPLE OR TUNERS TALK ANOUT THIS ISSUE. THIS WAS A HORRIBLE EXPERIENCE AND I DONT WANT THIS TO HAPPEN TO OTHERS.

Like what your doing and how your taking your time to have it running right. i don't own one of these yet, but around the 6:50 mark in the video instead of pitching the wires with the fuel cover, none of those rubber plugs lead too the fuel area? Just thinking how long those wires will last with people getting in and out of the car
