2.0 TDI CR 136 Audi A4 Build Thread

[aidanryanA4CR136]

Hi lads,

First time on here. Just want to see if anyone has built a B8 audi A4 on here or any 2.0tdi Common Rail builds.

Currently I'm at 190whp(210hp@flywheel)/420Nm with a remap, Cr170 turbo swap and dpf/egr deletes.

I'm wanting more power and looking at doing a 2.5" downpipe from FMIC.eu , larger IC upgrade, Sachs Performance clutch, GTD injectors (04L130277AE), CP3 R70 Pump and was going to go gtb2260vk on stock cast manifold. (searching for 270+HP)

Is there any other turbo options you guys would recommend? or any other upgrades ye would recommend.

Thanks in Advance

Gtb2260vklr, gtb2060vklr or gtd 2056vz or gtd2060vzk, etc. basically same power output as the vk but better spool ! Although the old gtb2260vk is really hard to beat…

The crankshaft is going to be your weakest link next along with the rods…also upgrading the valve springs and new set of aftermarket cams might also need required to reach your reliable goals ! You will definitely need someone that know how to tune CR and a 4 bar map sensor as a minimum ! Keep us updated with the project and upload some pictures of the car as well, sounds well meaty !

I haven't heard of the crank being a weak component of these engines?

FYI its a CJCB engine code, oval port.

Hi Lads, I have a CP3 and Fuel Metering Valve and Fitting Kit for Sale.

90,000km on Pump
Fitting kit never fitted (XMAN - Brand New )
Brand New fuel Metering Valve (Bosch 928 400 643)

don't go for a GTB226X hybrid turbo. go for the GTD226X hybrid's!
they spool better, and use a newer generation VNT nozzle design.

if i couldve found a GTD hybrid with a GTB manifold flange i would have bought it over my GTB2266....

@Xtremefunky picked up a GTD2265 i believe for his car, and it works amazingly well with supporting mods and most importantly, a PROPER tune!

given you are not in the US, your fuel/diesel quality is likely much better than ours. imo keep the CP4 if you can stay on top of maintenance / watch for metal flakes. the CP4 is capable of higher rail pressures which let you decrease injection duration. you can put an upgraded plunger into the CP4, and use an upgraded metering valve to let it flow much more.

i believe there was also a mod you can do to you CP4 to increase the internal pre high pressure system from 6X PSI to 1XX PSI. i recall seeing it some time ago but i'd need to dig around to find it again.. something about an internal spring / regulator seperate from the metering valve

The cr head flows bad compared to pd or ve, tiny intake ports and tiny valves + soft springs which let valves float at high revs.
I didn’t try the new gtd turbos but as I said I tried the old gtb vk and vklr’s and they are really hard to beat !
The b8 manifold is angled slightly downwards and there is not enough room for adapter plate on it to take a gtb turbo without fouling on chassis legs. I have an exeo which is basically a b7 with a b8 cr engine, I made tubular light manifold and it’s very close to chassis leg with a gtb turbo and that’s very compact with vk housing and no adapter plate !
The gtd are required to be welded to stock manifold and unless you push it upwards you cannot fit it there easily ! Also the discharge flange being v band is kinda long so it will foul the bulkhead…the gtd is easier to go on transverse engines…
