M30 Swap - e30 Fuel Pump Change?

[porschelou]

Just curious - we haven't had our car on a dyno yet but it feels like power rolls off around 5k. We have a b34(new rebuild/b35cam/head work) in a 86 325. Do I need to up grade the fuel pumps for the m30 motor? Just curious what others have done.

I'm always afraid of running lean.

Don't be afraid, install a wideband and know.

Okay - I have a LC-1 I have never used - guess I'll weld the fitting in and see what is says..

Wasn't sure what the "standard" is with a 325 "e" fuel system suppling the M30. The hard part for us is that we can't drive the car on the street. Might have to do a couple of quick runs I guess.

Thanks
