Very nice looking install... out of curiosity, do you think that stock exhaust manifolds/cats could be squeezed in?
Did you have to do anything extra for cooling?
What did you do for fuel feed?

Impossible to use any combination of factory LS manifolds. Steering shaft is in the way every time. Custom headers required and shaft goes between the runners.
I am using part of factory hard lines, I have AN fittings brazed onto the end of them, then they connect to Corvette FPR and Braided line from FPR to the rail with a EFI Adapter.
Here is a picture of the FPR assembly.

Do you think one of the stock manifold flipped upside down would work? (sharp turn on exhaust tube to run someway)
Mostly curious because of Calif smog. My stock engine is rapidly approaching 300k and I've considered an LS swap.
Are you using the stock BMW pump?

Exhaust should be ready tomorrow and tuning should be done Wednesday.

So the driver side manifold would be an issue? Passenger side would work?

Good news and Bad news.
Good news is exhaust is done and car was being dynoed.
Preliminary numbers it made 400whp and 380wtq.
Bad news is car lost fuel pressure 5 minutes later, 0 psi at the rail.
Replaced fuel regulator and it still sits at zero. So my brand new walbro pump took a dump! I hate those cheap *** pumps! Going to get a Supra Denso pump. So no car until tuesday
400whp would of been so nice today! GRRRRRR..........

Kaane,
My Walbro (external) fuel pump lasted 15 minutes before it crapped out. Curiously, the replacement one sounds different and quieter.....maybe the first one was defective from the start.

I've had my walbro for a few years now (unsure of the miles) w/ no problems. Used one in another swap and had no issues. There are a ton of knock offs out there though.

So what are you going to do about smog test? Smog keeps me from wanting to do a swap in anything newer then 1975. I've already went through B.A.R once.
