PSI did a Pure Turbo upgrade in this 640i!
How do you feel about the N55 platform?
We can tell you we love it a lot more with some upgraded bits!
The Pure Turbo stage 2 upgrade for this 640i is engineered to reach 500+whp. Some of the features of this upgrade are:
-Upgraded Point-Milled Billet Compressor Wheel
-Upgraded HiFlow Turbine Wheel
-Dual Compressor Oil Seals, Dual Turbine Oil Seals
-Large Diameter 360 Thrust Upgrade
-Extensive Turbofold Modifications and Machining
So we paired it up with some other upgrades such as an intercooler and JB4 to see what we can push out of her.
What stands out the most to you about the 640i? For us, the retrofitted front bumper makes all the difference. This isn’t something we see often, so this was a treat for us. This bumper absolutely changes the look of this thing and we love it.
