i want to upgrade my 1.9 tdi AFN with a bigger turbo. What do you suggest? I don't want more than 200 hp.

Wait your opinion!

if 160 hp is enough take the one from 130 hp PD - gt1749va . I did its plug ´n play on longetudinal AFN engine.
Observe different turboes is plug´n play according to engine mounting. ie. transverse or longetudinal.

the biggest turbos you can put on your engine are 1749vc or bv43 both you can find on 2.0 tdi 170 bhp.For the rest you need to loose the oem air filter and case which is not that good =)

the gt1749vc is not a straight fit..
it will interfere with the engine mount...

right the vc is the one without manifold,the vm is the one i'm talking about..it will go on np,as the manifold is more flat,iirc there is still 1-2cm clearance or so.

as for the airfilterbox...
I fitted one from a 2.0TDI B5.5 passat... with some trimming of the snorkel it will fit...
the inlet opening on top of this 50% bigger than stock..
but the maf opening is bigger aswel....

you need bigger nozzles,bigger pump head 11/12mm pump head would be fine,fmic is also a must,3 bar map sensor and ofcourse a good turbo.
If you can't find the 1749vm,drop me a pm i'll help you.

Listening in here :) pressuming they will fit my car as well (then out goes the 1749va .....may be)

-What is safe boost level for the two (edit 1749vm...not vc) turboes ?
- Are they plug n´ play ?

On some of them,if not all,inlet oil flange screws backwords,however you can easly make another flange just like your oem one that screws backwords,at least that's what i did.

yep...
you will need to trim the part of the snorkel that screws onto the front of the car...
it will need quite some trimming ;)

also you need a bigger MAF housing, or an 80mm pipe and a MAF-delete in the software (like I have)...

Ok, i will look up the part # in ETKA for the airbox first and then may be ill do the MAF delete, since i have VCDS. Need to look into that topic later....

Go for a gt2056v or gt22v, they fit not pnp, let me finish mine gt22v and i will tell you all the work you should do!! doesnt seem too much work, depends for who, im a mechanic!! is prob easier being in the car industry :), mercedes turbos like gt22v from 270 cdi engine have the exact same oil lines, same thread and diameter so not to worry for that.

has anyone fitted a BV43 to an AFN Passat?
What did the GT1749VM turbo come one? That bolts straight on and is an upgrade over a VA?

Going that vm is not going to fit,1749vm vw version is found on some 2.0 tdi 170 hp,or you could use a passat 1.9 105 dpf manifold and a vc interior and intake case,i'll make a pic later.

i currently have a decat pipe and don;t want to have to change that, so if i put the PD BV43 turbo on my AFN Passat would the turbo flange be clocked the same (the 3 fixings attaching the turbo to the cat pipe) - are these the same as the standard turbo?

I fitted Struikiestyle Passat box, but with AFN top box...
Works deliciously, also use the AWX inlet manifold :)

very nice pictures! btw, where did you get that plastic cover to the right? (left on car)

Since we`re OT.
Ive fitted AWX turbo on my AFN a4 1.9tdiq, also bigger nozzles, FB PP764.
Can anyone suggest me a chip/sw that will work with this?

Ive been looking at 6.speed from the facelift ATJ engine. will this fit my quattro along with the diff, etc?

thanks,
hans - norway

Hello there,
My 1749 va blew up...so i put a gtb 1756vk. I'm still on the stock injectors and the soft for the 1749 va. With the new turbo after 3400 rpm a got major power loss. Why? I made some logs but i can't attach them here. How can I do to see them?
