low mount turbo header
Ok hello everyone I have a 2.3 gm quad 4 in my beretta. i want to change up my turbo setup i'm really looking in to buying a hx40. I want to mount the turbo below my headlight behind my bumper so this means having a pretty long header. My old setup had a log manifold and spool was fast. My question is will having a longer header cause more lag? Also in mounting the turbo there it will cut down on my intercooler piping by a few feet. And also would i have a oil drain problems. Thanks guys

if you design the header well enough, you should not see much of a difference, if you keep the primaries sized to the exhaust ports spool should not be a huge issue with a properly matched turbine...in which an hx40 may be a little big...but i'm not an holset expert, so i do not know what they like

it depends on what you want out of the car. i know i just recently took my pro-made ram-hornish manifold off in favor of a HMT log and i would never go back.
But thats cuz i like to go when i wana go, with the tubular it was like a stock rex waiting to get kicked in the *** at 5k rpm. it was a big ol kick but the log lets it happen alot quicker.
I knoticed from my experience that when the turbo gettings spining it pegs max boost quick with the tubular, but the log starts building earlier and comes on much smoother.
