I’d appreciate any recommendations/experiences people have with turbo upgrades for the GSW/AT. I was initially thinking IS20 with UM/ED/APR tune, but have read with interest about some available IS20 hybrids (Littco, TPC20).
The car is my DD and I plan to keep it long term, so overall reliability and longevity led me to look into hybrids with upgraded internals. I don’t plan to drag/track/redline, but am looking for a much more enjoyable driving experience (fun dad wagen). I also live in Southern California, so i’m reluctant to add a downpipe due to CARB/emissions reasons. Rs7 plugs, an Intercooler (possibly) and eventually a clutch (once it slips with the added power) would be future additional mods.
Currently running stock exhaust, stock gutted intake with the popular mods, MSS Sport Adjustable springs, aftermarket wheels/tires/spacers, Golf R RSB.
Would the L38x/L430/L450/other available IS38 hybrids require a downpipe? Should I just run a used OEM IS20 with a tune/JB4 and call it good? Send an IS20 into Littco or TPC to upgrade? I’m not looking to make max power or best any track times, just get into the 300+ HP/TQ ballpark with a turbo that isn’t itching to implode. Thanks!
