they must have just done the same thing as u flipping it upside down to clear the steering box

Anyways, Finally time for a well overdue update on this

No point in slapping on a big turbo & having a 2" restriction on the intake manifold, so the plan formed

& finished

then figured out the piping from the turbo to the manifold

then, the VNT Controller Servo motor being controlled by an arduino which is at the moment just reading boost pressure from a sensor & Mapped for the veins to be fully open at 1.5 Bar Boost

Turbo & servo in its final position, anyone notice the colour of the wires yet :nod:

Oil feed fitted & EGT sensor added

Then to test it out, this was recorded last friday night, working incredibly well boosting full under no load.... We picked the right turbo!! We were extremely suprised

saturday we stuck everything else back on & did a job on the cold air intake, straight in through the headlight

Bit of a job on the front bumper too, oh yea & 25mm spacers all round


Completely Un-Tested we loaded up & headed to tynagh sunday morning to have a lash at a grip day & weed out any issues the car may have & test out the turbo & setup. Drift car come Track car huh?


Trying to keep it composed & in a straight line with 225 dunlop SP Sport road tyres on the rear was a challenge even in a straight line down the back straight in 4th gear, there was just so much torque and so much extra power the full way up through the rev range where the original turbo used to drop boost pressure this one just kept going

changed over to wet grip tarmac tyres on the rear & it kept it a wee bit more straight, thats when the power gains really began to show with the speed I was getting down the back straight. Its hard to tell exactly what its like tho having been so wet for the tracktime we had



As the rain suddenly took a turn towards a downpour I had a wee bit of a moment on one of the hairpins saw the front bumper eating some tyres in the centre of the track, luckily intercooler escaped unmarked! Bumper will be fixed with a cabletie or two


so.... What did we learn from it all? I spent some of the day getting the turbo close to perfect at 1.5 bar constant between 2000rpm and 6500rpm. Best bit is I ended up not opening the veins fully to keep it at 1.5 Bar which meens theres plenty more potential in this turbo yet .. 2 Bar & a bigger plunger in the pump next VNT Turbo For the WIN, best decision ever!! The servo did not melt sitting on the rocker cover & thats well tested after getting the stones driven out of her on sunday. All is good And a good few more ponies especially in the high high revs now.

On a side note trying to keep a car in a straight line when it has a suspension setup for drifting is extremely challenging. We'll be getting original wishbones sorted out for the next day & bring back in the camber for grip days

Great work man, some really good updates, look forward to seeing more.

2 quick questions for you there can you do the evry mod to a 318tds , and if the clutches from a 525tds fits the 318 as the standard clutch is useless thanks in advance

Yes evry mod will work, but a Remap will liven up the Horsepower much more in higher RPMs as the ECU begins to lower fuelling gradually after 2500rpm

No clutch will not work much bigger dyameter in a 6cyl

Love this, fair dues for going a different route, researching and trying things, id like to see what power this is making... keep the updates coming!

Right, to close out this thread from me, I have sold out my half of this to Owly as I have started a new project, a 330cd "M3d" (Click HERE).. That said, Owly will continue the work on this car (I hope) so this is his thread now. There is also another TDS Coupe Project by another member of the team who has helped with this project to date, so I will be posting updates to that also.. (Click HERE)

Right so for my final update on this
The 2nd flywheel didnt hold up to the hammering it got during the last track day, so we got Flywheel number 3 machined up & in the car ready for the IGR Drift Day,

we also got methanol installed on the new manifold to keep everything cool



new control panel made up

& the LED Dash also hooked up for monitoring everything

the arduino sitting in behind doing its job controlling the turbo to perfection all day, wired with some of the finest shielded Rosenberger cable (Genuine OEM for new BMW's may I add :P)

And to sum up our day at the IGR Drifting event in one picture

Turns out Oil Coolers dont like being dragged along the ground... Put every bit of oil out onto the track in moments as soon as it ruptured!, after that we had nothing but oil pressure problems :/ ended up being towed off the track a second time with Oil pressure issues & that was that for the day :/



So thats all from me on this project, its Up to Owly to continue the work from here & keep this sideways
