RHD m54 b30 turbo build

[AK427]

I don't want to highjack your build thread, but your thread inspired me to actually execute on my plans to turbo charge my drift car. Conclusion: a turbo setup in a RHD BMW is not so easy. Specifically as I planned for individual runners and a top mounted turbo. Never build a turbo manifold before, but the RHD steering rack location is a nuisance. And a 3" down pipe is not helping as well. Ended up with 2 runners wrapped around the down pipe. These are separate pieces fixed with V-bands. I really hope that I never have to mount them again as space available is limited, and they are difficult to reach.
Without heat wrap I had about 10-15 mm play between manifold and body. I hope it is enough.

But it is done, and the car pulls hard from like 3000-3500 rpm. I've installed 6 psi spring (stock engine), and will increase boost with manual boost controller during dyno session. Boost already starts to build around 2500 rpm, so I'm pleased with the result so far. Enclosed some pictures which I hope will inspire you. Good luck with your build.

Cheers,
Adrian

Great job on the manifold, looks great.

That manifold is a peice of art if all works out OK would you consider building and selling them ��

Hi Adrian where have you mounted your waist gate I can see the pipe for the waist gate and do you have any pictures with it fitted.
Thanks
John

That looks Brilliant! i know what you mean about the difficulty of a turbo manifold for a RHD, i keep changing the location of the turbo, so much so that i think i'm going back to a bottom mount! im currently fabricating a new engine mount arm to create more clearance....not easy! I'm expecting to start my exhaust system in the next month (when the parts arrive and i have time!).
On another note, the head of the engine is fully rebuilt!

I'm getting more and more excited to get mine finished, works just very busy at the moment so i dont get much time to work on it

Bottom or top mount will both have their challenges. Bottom mount might have an easier routing around the steering rack. I'm curious about the manifold required, but will not change mine ;-)
@JKMOTORS:
- the waste gate is mounted at the bottom (just where the pipe ends in the picture). It connects to the down pipe after the flange.
- too many hours have gone into building this manifold, and will not be interesting from a commercial perspective. But thank you for the compliment.

Just a small update,

Exhaust system- 2.5" single pipe system from the down pipe back, i'm using two mufflers, one is 18" long, the other is 10", this is going to be a daily(ish) car and i'm only going to be pushing 400bhp max when finished, i want this to be a reliable build so im not chasing big numbers (yet anyway ).
there is a section at the front where a de-cat pipe can be used when im at a Track day-Etc.
i haven't started the down pipe yet, but im planning on using a 3.5" pipe for this, space permitting.









Camber arms - i Took it upon myself to design and manufacture a set of rear adjustable camber arms, being an engineer, and having access to CNC machines, i did exactly that. for £50 i have made myself a set of heavy duty camber arms... WINNER! being me, i also put my builders mark on it





Cylinder head- the cylinder head is finished, i just need to work on the lower half of the engine now, i also had chance to fit all of my custom manifold flanges, all ready for tacking the manifold together now






one other brief note, i've noticed on a few of the Cam journals (Pictured), there is some light scoring on them, i've used some light sandpaper to polish them, i'm not too concerned this may be a problem, but would be nice for a second opinion has anyone else encountered this?

Coming along nicely.

[JKMOTORS]

Is this a dead end now have you given up or are you still building?

Its still going on, although painfully slow at the moment. i've been concentrating on getting my buisness of the ground so unfortunately it has been slacking.
Here's a small update though...

I have finally got the car back on 4 wheel's so it's good progress! I've fitted some 360mm discs up front too, ready for some brembo's
The discs are from a range rover sport and cost £89 for the pair...winner!

Also, i believe i have 'The' solution for the infamous oil pump nut, I have designed and made my own version of the 4 bolt system, yes it is based on the GSR oil pump shaft but I have decided to remove the dowels from the design, using the centre diameter of the shaft to centralise the sprocket. I am also using nord lock washers to prevent the bolts coming loose. Despite doing this, I was concerned with the amount slack in the chain once I had test fitted it to the block and it made my wonder... Why isn't there a tensioner?
I had a tensioner from an audi 1.8t (20 valve) engine laying around that I rebuilt a while back and offered it up to the block... Looked perfect to me! So I modified the block by drilling a 3mm hole for the spring and tapping a m7 hole for the tensioner to bolt to. Looks great to me and there is tons of clearance when the cover is on!

I'm going to prove that the harmanics of the engine are not to blame by performing some tap testing on the engine, esentially im going to be inducing a vibration through the engine by means of tapping it and measuring the harmonic frequency of the engine it gives of, from this data we can calcualte the maximum resinence and predict how much vibtation/movement is occuring. it should be intresting to find this data out.

my personal opinion is that due to lack of a tensioner (Thanks BMW) the chain is acting as a jack hammer on the return to the oil pump sprocket and working the nut loose.





I've also put together a specifically designed Oil catch can kit for M54 engines, one of which i will be fitting to my car. i have tested this set-up too with good results.

This is as far as i have got though for now

I have a question if anyone can help me. I'm curious about the pistons from a N54 engine. I'm wondering if it's possible to use these pistons as a cheaper alternative to buying custom forged pistons, I know they are 84mm just like the M54 engine but I wonder what the compression height of the N54 pistons are? Can anyone help out? ☺ Google was not my friend on this one lol

Bump for an answer but I doubt they are interchangeable.

[parkin001.tp]

yeah i found out they wont fit, the compression height is different, thats a shame.

now back to making some new stuff

[james274]

Any More progress on this build? loving the workmanship involved, I wish I had access to CNC, im doing a low Budget Build at the moment, Mk4 Ford Escort with RX8 running gear and an M54B30 and Turbo.
Ill Post a Build thread soon.

[nemus05]

Amazing!!!

Is this build still on going? Maybe given up and moved to Barbados? ����*♂️
