Hi guys i have a 2006 a3 tdi 140bhp bkd engine. Have a stage 1 remap to around 170 175bhp . What mods are recommended to run around 200 220 safely has anyone else done this if so just wanted opinions on how they drive and power ect thanks
2.0tdi bkd next stage?

A hybrid turbo should get a healthy BKD to 200-220bhp (1.5-1.7 bar of boost).
Edit: Decat obviously if you are allowed to do that in the UK.

A couple of precautionary items need addressing first.
2006 A3's are the best of the BKD engines as they have no DPF but be wary of the following.
Have the oil pump uprated with the new larger keyway if not already done.
Remove the sump and clean out the oil pick up pipe, they are susceptable to clogging up if the car has been on long life service regime in it's early years.
Check you have the later 'C' stamped cylinder head, older ones can be porous.
Fitting a sports cat will maximise any further turbo and mapping upgrades.

I was looking into the hybrid option so may go that route
Where abouts can i find the part number for cylinder head and is the oil pump an expensive upgrade
If i get hybrid i wud like all oil feeds cleaned up also want decat or sport cat too

Isn't that a fix for some of the common rail engines instead? Or does the BKD also suffer from oil pump issues?

Pretty sure bkd in the a3 doesnt suffer with the oil pump key issue. Also thought the pick up pipe issue was a tfsi thing?
Pourious head issue is actually an issue, B and C are safe, A can can be a bit of a ticking time bomb. If you give it a google there are loads of youtube videos showing you how to check the head, 2 minute job to do, just life engine cover

2.0 BKD is one of those rare engine codes that has the reliable old style 1.9 PD type chain drive .
Happy days .

Hybrid turbo, and maybe a new clutch depending on the amount of torque and quality of map and the state of the existing clutch.
Easy to get it mapped so it delivers a big dose of torque resulting in wheel spin or clutch issues. A good map will deliver strong smooth pick up without a vertical rise in torque delivery.

Thats good news to hear about the oil pump and feed. Im hoping the clutch will last a bit as only coverted to single mass 2000 miles ago . Theres alot of companies offering a hybrid turbo to 230bhp spec for around 450 to 550 so i may look into that and good map. I will check out the head part number 1st tho
If the oil pump isn't an issue, then a 2006 BKD is even more reliable than the rest of the derv line up. Spend your dosh on an uprated clutch and brakes first.
Ive got a 4pot alcon brake kit i fitted the weekend just the clutch i may need to look at but its only 2k old so might just wait until it gives issues
Ooooo Alcons, Nice set of brakes you have there but maybe a bit OTT considering the age and value of the car.
Only got them as i work for them so cost me next to nothing for the calipers pads and bracket set up probably cost me less than replacing discs and pads of original wouldnt of paid retail for it lol wud be over kill
You could easily run a standard clutch using that power, obviously keep an eye on the torque delivery, imo SMF'S are a ball ache on this engine/gearbox, the rattling noise WILL wear you down as well as the syncros 1st and 3rd gear syncros on mine were shot after 40k miles! I had one fitted and ran it for 40k until the clutch burned out now back to a standard clutch and flywheel, you can never go ott with brakes in my opinion of course Never had or heard of oil pump or sump pick up pipe issues in my 10years of messing (I mean modding) this engine
BUT that's not to say it hasen't happened of course

Cheers mate i only changed flywheel due to my old clutch and dual mass being battered when i brought the car. The brakes are ace 4pots running s3 345mm discs. Im just trying to find the best hypbrid for reasonable price. Is the turbo swap a hard job ive been quoted 160 for the job

Turbo swap if nothing has gone bang is a fairly easy job.
And @martinivw is right about the fly wheel. Be careful as while the dmf had a tendancy to go pop, it was due to it being the first point of failure. Strengthening it has moved the failure point somewhere else, typically the gear box. Just keep an eye out for rough running and get it fixed asap.
@martinivw quick question, so stock clutchs are okay for 220 to 230bhp with a hybrid? I would go custom remap to keep torque down etc. My cars coming on 100k miles so the big debate at the momment is uprated clutch or just standard when it goes.

BKD in the A3 doesn't have oil pump issues indeed. Regarding the cylinder head, even B heads aren't completely safe, I have bought a C head for that matter as with my previous head, car was drinking coolant like crazy.
Regarding the clutch, yes it can take the 220bhp but it WILL go out in less than 5000 miles, even on a nice smooth map - anything over 298 lb ft of torque completely kills the stock clutch.
This is all from my experience.

Mine was mapped to 205bhp & 305lb/ft by dark side and my Luk standard clutch seems to be good so far for 6k spirited miles lol
Mine was over 100000 miles when hybrid and clutch were fitted, as long as it's serviced regular it should be good, check for "devonmikeboy" 'S posts on here he was the best for Diesel tuning knowledge a few years back and i pestered him for months about torque values etc, I'm sure he has a post with standard clutch limits somewhere good luck

Thats great thanks mate il try searching for him. Id be happy with 205bhp. Whats it feel like against other cars and what hybrid did u get that from
I have been talkin to xman and been offered the hybrid for 600 no exchange i was wondering if anyone had used these turbos to see what they are like are you running one

had one many moons ago ,one of the first to hybrid one . had rolling road tune and settled on 231bhp with just a hybrid and decat . did get 242 but smoked like a old locomotive so de-tuned slightly for alot less smoke . drove it for 2 years on standard clutch and dualmass with no problems
still have custom tune file somewhere for it

Thats some good power that is. I would of been happy with anything over 200 to be honest. Who tuned your file mate would like to get some advice for my tuner . What torque was you running and boost

Probably VERY smooth torque curve (almost like naturally aspirated petrol car). Mine was very smooth but stock clutch still went bonkers after a few thousands of miles.

Ah fair enough. Is there really any point hybridising and then fettling the power to save a stock clutch?
that why most people bofore doing anything just asking, like this post, and anyway depend of plans of @Matta3sline. If he wanna some bigger turbo because of budget he need to limit himself on only turbo now or he wanna only 200+bhp. If your goal is taking 200+bhp only turbo get hybrid and you will get up to 220bhp on stock injectors (and downpipe need to be larger than original one). If wanna more take some modified exhaust manifold and then put an gtb2256 or gtb2260 and then injector nozzles supporting clutch, check your components integrity (specially head, pistons), uprated water as well oil pump, maybe pistons (depend of power you expecting) camshaft bearings, cleaning of sump etc... and you can go 300+bhp. Or for the same (or less) money put an 4.2 tdi from a8 and modify brackets, mounts, front carrier, drive shafts for it.
I would be over the moon with 210 220 bhp i dont want to push any more and make it unreliable to drive and cost me a fortune i just struggling to decide on a hybrid turbo there are alot of compainies offering alot of different ones
unrealiable? if done properly is realiable, so if you wanna a 220hp you can do 2 things:
put hybrid (welded on manifold) or do custom manifold and adapt to gt2256 that in future you can upgrade easily
