Just sold those and shipped them out but it think it was engraved or actually looked more like metal stamp.
Hey everyone. I was wondering that here is so much texting about 2.5TDI in the year 2023.
Im from germany and going to to do a modify to my Audi B6 the next few weeks.
Until now i drove a 2052 Stage 3 from H-Turbo with ****ty East Europe Nozzles, FMIC, and a empty stock exhaust system.
It makes around 300hp. But the software was made in eastern europe so its very very bad and smoky.
So now im going to make me a complete new and stable 2.5TDI BDH. I will seal the complete engine new, new head gaskets, surface grinding the heads, new camshafts full material from "Kolbenschmidt", new valve seals, rebuild VP44...
I also made me a pair of exhaust manifolds out of the ones from 2.7BiTurbo, so i wont have problems with cracked stock ones. Also going to find out which is the biggest size of FMIC i can mount in a A4 B6. Clutch were made from a friend of me, its a Sinter who can make around 700Nm. Flywheel is a new stock one, we will see how it works.
The Turbo will be a Holset HX35 with steam wheel. RPM will be increades to around 6000. My Goal is to get around 381hp. I will see and im confident a "****ty" 2.5TDI can make more HP than an stock Rs4 B5.
Or is there a better more modern Turbo to go for 380hp? Sometimes i thougt about a 2260 Hybrid?
So now i have a question about you Diffas. I read often about using other valve springs when going about 350hp. Whats the advantage of doing this step? Which one can i use for my BDH heads?
I also wanted so ask if anybody know people fitting a HX35 on 2.5TDI. Which nozzles should i get to make 380-400+HP?
