To resize pictures you can use any software, but this is before posting them. Ex. Windows photos, gimp... Acdsee, IrfanView.

Try to overlap the 2 drawings around the common bolt to find out the angle or position of the bolts and holes so you can make a flange like on the website. That one is made for transversal engine. You need to use your exhaust manifold to keep the turbo far from the mounting. If you make all the measurements, it can be done in Autocad and then cut with plasma or water jet. I did this for GTV2056VL and AHU manifold (the one in the pictures from that website).
I'm curios if you use the common bolt, the center hole is aligned with the one from the manifold.

Hello!
I will try to put my images to fit this page sorry about that!
I can fit this turbo charger this way with the factory bolt to the manifold and i have to drill one bolt for the turbo bigger diameter:

As you can see the manifold outlet and the turbo inlet port are lined up there is no restriction and the factory pdtdi gasket will fit!
BUT!! But the turbo will sit like this position:

At the first measurements it will fit to the car,i will need custom oil feed and return line as well as turbo support bracelet!
What do you think of?

If you rotate it to normal position (considering natural position of the engine, which is also rotated) to right, can a flange be used , there is enough space to put bolts? The flange should be bolted first to the manifold.
If you do like I said, please make measurements, angles, distance between some bolt, maybe I can draw it in Autocad.
or....you can weld it to manifold in the right position.

Hello!!

With this position i can bolt right up to the oem manifold!
i think if i use an adapter plate maybe wont fit because of the adapter plate thickness.
I dont want to weld to the manifold because im afraid it will break off i would like to use bolts as i said i could bolt up to oem manifold only bad thing is the turbo sits like that position but i think it will fit to my engine bay without any problem.Just need to make custom oil feed and return line and ofcourse intercooler outlet and exhaust flange!

Was this for longitudinal or transverse mounted engines?

AWX/AVF/AFN etc. they are all the same manifold- longitudinal engines... I have done it before, wouldnt recomend it as the OP has a PD bv43 and it was a natural thing to go to a CR bv43a as the CHRA swaps over between the models. However the CR exhaust housing has larger spacing and larger hole to exhaust spent gases so i would use the CR hotside if i was in his position just for better flow ! However the CR hotside poses the above mentioned issue with turbo sitting at an odd angle...

I'm asking because i have this turbo and i want to make it fit on my own car. It has a transverse mounted engine.
Maybe someone knows what manifold to start with?

As above, AWX/AVF manifold with a bit of enlarging the holes will fit. The exhaust needs to be modified a bit witha a new flange grafted in to suit. I have fitted a bv43a to a pd100 audi a3 so its doable. Custom oil drain, custom oil feed braided line and a pd150 intake pipe its what it took ! the car went well...

You need to make an adapter plate, look at Darkside Performance for examples and use a Passat manifold, which I think you have but can't tell as the pics are too big.

john.jackson9213 runs one, spools like stock, will do 200 chp. Whitbread made his adapter.

We have gtc1549vzk in AHH 1.9.
2.2bar, .275s maxed out on 11mm.

5.5s 0-100. 3.4 80-120. It can spool as low as tou want, your transmission/clutch will die first. We were requesting 1.8bar by 1800rpm, with fresh DMF/SRE, scary stuff.

Ok, so in the end you used AVF maniold and the turbo still sits at a slight angle, yes ? Nice to know there is no lag, i think you had a duff bv43 to start with...

Hello guys!!

Yes i used an oem avf manifold i just had to drill bigger holes on the turbo,used oem gasket for the 1749va..thats all , yes the turbo is sitting in a slight angle but is okay i have got the oem air filter and it was easier to tighten up bolts for the turbo and the oil backflow line.
Later i will upload more pictures maybe that can help.
About the boost: as you guys know i had a bv43 from a 2 liter pdtdi it was very very laggy i dont have got boost or i had very low boost under 2k rpm it wasnt fun to drive in city....after i replaced with this turbo ....Wowww
Even got boost in 1st gear...and the throttle respon time was amazing there is zero lagg i mean really zero when you push the pedal immediately boost comes..at the moment i dont had time to put a good remap on her so its needs a little more time but it was worth it!!
In vcds basic settings with the bv turbo i has 80mbar difference on-off with this turbo i had nearly 200mbar something like 191mbar....

It’s quite common for the actuators on bv43 to fail and give this sort of bad spool...it’s nice to know that the new turbo is good for a daily driver, most forget drive ability when it comes to tuning with larger nozzles and big turbos !
