Reviews of BorgWarner turbocharger

I have this turbo but t4 twin scroll with bigger AR. It is too small on my half Bridgeport 6 port turbo fc.

I went with a BorgWarner S257SXE... 515hp at all 4 wheels on Ethanol at around 21 psi. Spools faster than OEM twins.

man those EFR turbos were fucking lit.

Quite a few years ago I bought a Borgwarner EFR6758 for my build, and it was a stellar little unit.

3 weeks after posting this and my turbo locked up on the hot-side... Car ran 10 degrees hot out of nowhere and then a loud pop followed. Checked everything and it seemed okay. Except the turbine wheel didn't want to spin. Absolutely locked up. Friend driving behind me saw more black smoke than usual during the pull followed by a blue-white "puff" which we agree is when the turbo died.

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.

the ckra turbo is absolute garbage. You need to have an upgrade in mind because it's not about IF it'll fail but when. Regardless if it's stock or tuned. It just sucks.

The absolute cheapest brand new turbocharger you can buy for those engines is an aftermarket BorgWarner and will set you back no less than €1000 + shipping.

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