I haven't been on the forum for a couple months, has this blown up yet, working, or waiting?

N52 trans gave up long before the engine, so they did an N54 trans. Really cool car. Same car that did 9,000rpm on the dyno repeatedly, was dyno'd with an open intake manifold (half cut off, basically making velocity stacks), and was the guinea pig for all their tuning. Also, only the outer block of the N52 is magnesium, almost everything structural is aluminum, so it's still quite strong, and it's proven.

The N52 was raced for years in Grand Am in both the 328i and 128i. The 335i and 135i never raced in such a fashion.

Pretty sure the engine had over 200,000 miles too, but I could be wrong.

But he’s going turbo and it will make substantial boost lower then 2500 and be making serious power quickly up the tach from there.
Too much hp, tq no matter how it’s made won’t make a difference in car not built for it. Power WILL find weaknesses.

Lets just wait and see what it makes on the dyno lol. This is a dyno graph by the other N52 Turbo I've been talking about at 12psi on the ebay turbo which is smaller then my boost labs 5855 turbo.

Also looking at ordering some precision racekwork ignition coils. N54 Aluminum intake manifold and a oil cooler. as well as the Milvs.

Hey bud, did you ever get this sorted out?
