IS 38 Turbo

[InsaneAsylum]

Okay.. there are not many places in Melbourne that have a software package for the Tig on the IS38 Turbo. So I will upgrade the intercooler and downpipe. I do not want to spend money until I know for certain that i can upgrade to the IS38. Do you guys know any other places I can consider to do this? I am only in the planning stage.
My thought process was I have the CHHB engine and IS20 turbo which is the same as the GTI so they should be the same to upgrade. There are so many GTI guys that are upgrading their Turbo's to the IS38.
thanks in advance.

Wouldn't fitting an is38 make your engine the same as a Golf R engine and therefore a Golf R stage 1 tune would be appropriate, or Golf R stage 2 if you're fitting a DP as well.

I would still stick with someone like Underground Performance or Etuners or Vtune Performance. Ben from Tarmac Engineering (Spectune) works with Vtune for their tuning files so im sure he could do something suitable for you. Another place to consider would be Peter from 3bar Performance.

You need someone like these places that are capable of doing custom tuning - places like APR / Revo / Racingline etc wont be able to help you as they only do off the shelf stuff for common configurations. If you don't want to upgrade the intercooler or downpipe then just tell them you want a milder tune due to standard hardware except for the turbo - you should be able to get something close to a stage 1 result on a Golf R which is around 220-230kw at the wheels which makes for a fast car.

Thats the same way i am thinking but my internals are the same as the GTI.

thanks for the info,that is a big help. I am just waiting on feedback from one of the providers. How does this affect my VW warranty if i went ahead with this ?

You can kiss the warranty goodbye on your engine and transmission.

There are further differences between the two engines beyond the turbos, so a Golf R tune is not a plug-and-play proposition.

so best option is to upgrade to a Golf R?

Thanks for clarifying that, I wasn't aware. I was under the impression that the Golf R was essentially a GTI with a haldex/4WD and an IS38
