The car Dynod at 301hp 338 tq on low boost (jb4 map 1 on pump gas)

I tweaked the boost numbers on the JB4 and it definitely pulls alot harder now. I probably won't be dynoing it again until I get back from vacation next month.

What about your engine internals?

I thought there were some other changes? Like Con-Rods etc?

This N20 is fast. Finally got a chance to see it in person handing out quite a few losses.

Well I don't know if it'll be a 235i killer quite yet but... Just wanted to share my turbo upgrade that I'll be receiving later this week. Took a couple months but the wait is over! I can't wait to install this and pair it up with full bolts! We are expecting a 35-40% hp increase over the stock turbo. The internals have been beefed up and are now a lot larger compared to stock internals. I'll have exact specs of the internals later on this week. I will be running the JB4 stage 2 along with meth injection, e85, rolloface chargepipe, injen intake, evolution racewerks intercooler, Arqray catless downpipe and ARK performance exhaust.

Turbo upgrade specs:
OEM BMW N20 TURBO
COMPRESSOR: 56/42mm TURBINE: 47.3/41.2mm

HEXON BMW N20 TURBO
COMPRESSOR: 60/48.5mm TURBINE: 52/45.6mm


Here are some of the pics the guys from Hexon Racing sent me via email. I'll make sure to update this thread once I have the turbo in my hands.

















Hey there!

I'm researching different turbo upgrade options for my M235i and Hexon had an option for the N55. Could you please let me know how your experience has been?

Thanks!

Correct... I did blow my motor and I rebuilt it and tuned it again however the car is gone now. Had a pretty bad encounter with a center divider a few months back and the car got totaled
