What size injector's ?
 

Im currently re-doing my lq4 from carburetor to efi. I cam across a lsa Supercharger for cheap and rebuilt, So I went with that. My problem is I'm not sure how big to with injector's. Or will stock ones be enough

Set up
Lq4
L92 heads
Cam specs.
112° love separation
Intake. Exhaust
Duration. 281. 283
Valve lift. 0.571. 0.573

I'm ether going to do a 18% or 14% overdrive gilmer drive from LSXconcepts

I could not resist it, lord I tried, but what is love separation? Sounds like something I tried many years ago and cost me half of everything.(except the car thank God)

From what I've seen once you move past a stock LSA with 5 or 10% overdrive you will max out the factory injectors.

Either

DeatschWerks 90LBS are plug and play for the LSA or Injector Dynamics 850.

The image looks like you already have an overdrive (smaller) snout pulley. I would become familiar with this chart. you want to make sure you don't over spin the blower.

You will need a good fuel pump set up. Something like the CTS-V twin pump with a Vaporworks controller.

Right on I appreciate it, looks like I should be good with the 18% overdrive. I've looked into the id850's and apparently they stopped making them and replaced them with id1050's. I'll take a look at the deatschwerks. Thanks again. I'm a little ways out before I get to the fuel pump won't be on the road till next summer
