Full power was on around 3000rpm. I was really happy with that turbo. Sure it is 2.5 v6 but since it...

    G25-660 turbo on 1.9tdi

    I would never put that turbo on tdi, g25-550 would be waay better choice with 0.49ar turbine housing. It is still around 350-400hp wg turbo on tdi, so dont expect very low rpm spool. I had similar sized gtx2963r with 47mm compressor and with upgraded 53.5mm turbine, on 0.64ar iwg housing. It...

    GTB2365v overboost issue

    To me it looks like vnt control arm is too short and does not reach full open position. Are you sure it reaches maximum position ?

    a6 2.5 tdi ael hard tuning!

    Correct me but I think best solution for the tune AEL is to use edc15/harness out from the t4 transporter 2.5tdi engine and use n75 or use n75 pwm signal for controlling electronic actuator of vnt.

    How to replace cylinder head bolts?

    boost is quite irrelevate value here. It is more about how much fuel you are pushing, soi and rpm you are doing that.

    V10 and V12 TDI Conversion

    There is basically only one v12 engine and only cg-iron block. I'd rather would look V8 instead than v10. Not sure if the newest 4.0tdi is nowdays alu-block, probably not. Older ones are all cg-iron.
