Turbocharger BorgWarner or APR

Stick with a Borg Warner replacement. Buy once, cry once. The price is worth the longevity and reliability.

The ko4 I have is borg warner.

12k+ miles later and the turbo is working great, with a single caveat. Every so often I will get some turbo surge under WOT high boost conditions.

I have a S362-SXE and I have full boost around 2700-2900 (may be earlier, I need to dig through my logs to check). I make about 600hp and 550rwhp on pump all day every day, no e85. Perfect street turbo.

The turbocharger that APR uses is an actual Borg Warner unit that they modify the housing on. We never have to do any modifying of the APR K04 or the downpipe when installing them.

I have 40k on my car (30k on stage 2) and it's flawless.

I'm APR stage 2 currently waiting on a Golf R Turbo and a tune for that! Currently limited by my tires and suspension(only lowering springs, still too soft)

They are indeed extremely fragile, the stock CKRA BorgWarner turbo is not reliable and will blow. Its just a question of when not if

The CKRA has a smaller turbo than the CJAA. The CKRA turbo is also more prone to blowing up.
