Today we fabricate a single turbo manifold for bmw n54 engine, using an ebay gt45 turbo t4 flange link to other manifold video • 500hp ebay build bmw 3...
The second 3 header should start a slightly bigger piping..all 6 of those cylinders are fighting to make it threw a single 2 Inch pipe.. I would use a taper from 2in to at least 2 1/4in pipe right at the second header.. and would prefer a 2.5 to 3inch, if it would fit...and continue that 2.5 or 3 inch to the turbo manifold...if you can do that I will buy one for my n54.. 🤔 🤷♂️. My 2 cents!
Another part that will hurt flow is how the second 3 merge into the first 3. Having a "T" doesnt allow for smoother flow, it should have a curved pipe merging into it aiming the flow towards the turbo flange. Having a "log" manifold hurt top end and creates loads more heat over a partial tubular manifold but best is full equal length tubular. The wasgate pipe needs to be at an angle that allows the exhaust to be pushed into it over it trying to find its way to the wastegate. A 90 degree is ok but a lower degree allows for better boost control
Not trying to hate but just by the eye ball those two exhaust manifolds DO NOT line up! The hole for the exhaust stud on the front exhaust manifold appears to be lower than the rear slightly. Other than that I love the thinking out of the box approach! Nice work
Appreciate it brother i never had an issue with the manifolds bolting up to the engine🙏🏽 and i have new fixtures i made now that are 100% fit from cnc🙏🏽
Good job mabye add a fl3x pipe and a small v band I. ThE middle so its 2 pieces ea8se t9 i stall rem9ve and repair the car with a two pi3ce manifold is also a good selling point.
Appreciate the tip brother but the manifold isnt blocking anything major that you would have to remove in order to repair anything so no need🙏🏽also flex pipes are a failure point aswell on something like this for exhaust yes but for manifolds it will cause too much stress on the oem manifolds
Wish i knew brother dude never gave me pictures updates nothing gave him a deal if he would help me promote at the time guess he just took advantage of me🤷🏽♂️🤷🏽♂️ all good we up now🙏🏽🙏🏽💪🏽
@@frenchifab8663 since piping is for two little twins handling a single turbo is gonna put so much back pressure blowing up your engine I made my own manifold once from the stock one and blew up my n54
I drill my manifolds open bro its all taken care of already to relieve the back pressure stock manifolds have a hole about 1” for stock turbos mine are drilled alot bigger and 2” pipe also your tuner should be able to see any issues while tuning my tuner cd919 said car did great on my v1 manifold and makde 568 on e60 with slipping trans
@@frenchifab8663 I usually tuned everything myself. My brother is a bmw tech and he even said just dont mess with them but dunno if he knew about your method or not.
Super clean work man I love seeing the creativity and craftsmanship you have great precision and over all do a great job I love watching your videos
Appreciate it brother🙏🏽🙏🏽🙏🏽💪🏽
That work is clean, bro. Nice work.
appreciate it brother learning more and more everyday!🙌🙌

Can you give us measurements for the template

Now he's going strong he'll yeah 💯💯👏👏👏👌
U such a g bro fr
Are u using the Lift TIG welding method..?
Love to see it my bro!
Appreciate it brother🙏🏽🙏🏽
Make a V-Band manifold.
Nice work I was wondering if you can make some with bigger twin turbos than the ones they currently sell

what's the price for one of these?
🔥🔥🔥
Appreciate it brother🙏🏽🙏🏽
U don’t be scared if ur engine blows ?
Nah made 586awhp so far🫡🫡💪🏽🚀🚀
Looks damn good how would I get in touch with you to build one of these for my n54 I’m in charlotte nc
Appreciate it brother!🙏🏽🙏🏽 follow me on instagram frenchi_fab and send me a dm
What kind of piping did you use
Schedule 10 304l stainless
@@frenchifab8663 ok bet 1.5”??
How did the N54 do with the Gt45?
Wish i knew brother dude never gave me pictures updates nothing gave him a deal if he would help me promote at the time guess he just took advantage of me🤷🏽♂️🤷🏽♂️ all good we up now🙏🏽🙏🏽💪🏽
How much for one of your manifolds?
Hey brother follow me on instagram and send me a dm we can talk then🙏🏽thank you for the intrest🙏🏽🙏🏽 frenchi_fab
Were did you get the flange for the turbo at
I have a machine shop that makes them for me if interested they are $50🙏🏽
Would you consider doing a n55 manifold
I want to looking for a donor car to mock things up soon
Okay cause I’m really interested in doing my own single kit but your help will make it possible,I have a extra n55 turbo Manifold my turbo went out
I have a engine if would like to mock it up on I’m in the Lehigh valley
Dont use the stock manifold you will create too much back pressure usually blowing out cylinder 6 just fyi
Why is that?

its better to buy an aftermarket manifold by itself then mess with it if needed.

Who the hell can make that template I can do that with my eyes close 😂 what’s so difficult about that you are not building a rocket brother
There are plenty of people that asked for it 🤷🏽♂️🤷🏽♂️🥱
