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

 

Also for the holset guys whats the best size hx40

 

the length in the manifold will cause a lag in spool time but not much, and you might have problems with drain if you go to low, but you can always get a electric pump

 

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.

 

you will also have a better top end if you do the setup your thinking about. doesnt domestic guys do this?

 

i want to keep down lag as much as possible. I'm still up in the air with this setup, i could mount it in the engine bay but the means alot of rerouting fuel line, wires, and so on

 

sell car buy new one. jk good luck why would u have to reroute those lines??

 

cuz he has fwd chevy v6 = pain the the mother ------- ***

 

thing will haul with some lag or not though so dun worry to much
