VW Golf R Turbo

[Omari1996]

Hey guys I currently have a mk7.5 Golf R and am on a APR Stage 2.5. from my understanding the IS38 turbo (stock turbo) can only handle up to 28PSI before issues can start to occur. I have an APR boost tap and the gauge is saying that i run 28 PSI on full throttle. I am wanting to get the piggy back JB4 which i have for my Kia Stinger to mess around with the E mixture fuels. Now i know with the higher maps you go you start increasing the Boost/PSI so by doing so will I end up messing up my stock turbo? Will i need a big turbo? or a aftermarket tweaked with IS38? Any thoughts or solutions? is anyone currently running a flashed ecu and a piggyback?

Hey Omari,

From what I know, the stock turbo has its limitations, but I've seen sime hybrids go up to almost 32 PSI of boost.

I think it all depends on what you are willing to get from your car. A nicely done tune can get you some nice power figures with almost 30 PSI on the stock turbo.

One tuner from Poland did a pretty liberal map with 2.5 Bar/36PSI of boost with (from what I know) a stock turbo and he manaaged to get 350HP with a quick spool. The car only got an upgraded intercooler. It was a Golf R mk7.

But if you would like to upgrade the turbo, I've heard of some hybrids that blow over 32 PSI.
