Need fuel system/setup tips I need some help figuring out what to do with my fuel system and my pcm, if Im going to a 382 bore setup, expecting maybe 460rwhp range. Car has stock 26# injectors and stock fuel pump(2000). Id rather be safe than sorry, but if I dont need this stuff then ill skip it.
Thinking about 30# lucas-style injectors (too small?), and maybe a walpro or katech fuel pump...any thoughts? Also a good vendor who has these items?
Im a bit worried too because I have an Ed wright PCM, and its locked against LS1 edit, so does the pcm need to be adjusted for these changes, and if so do I keep doing ed wright or try and get it flashed for LS1 edit tune? Suggestions on best way to handle this?
Insight from similar experiences or setups appreciated...

Re: Need fuel system/setup tips depending on how long you've had your fastchip tuning, it may or may not be locked.
either way, ken can get you a file you can program over top of ed's file to make it all go away.
if you just go 30's maybe 36's you can get it ballpark with a maf translator but edit would defintely be better since you may want timing adjustment for the new motor.
since 36's cost the same as 30's basically i would get those (svo) and a walbro 340 intank pump and hook it up yourself, fairly easy.. and save a hundred bux or so from what racetronix sells.

Re: Need fuel system/setup tips Pick up the Plug and Play ARE 340 walbro intank pump. 30# injectors will be fine on a 460RWHP 382. Also get your PCM reflashed and tune it on the dyno with LS1 edit and wideband.
Good luck,
Chris
ps- If you are planning on spraying I would go bigger on the injectors. If all motor, 30# SVO's will be fine. (actually 36#'ers at Ls1 FP)
What vendor are you going with on the 382?

Re: Need fuel system/setup tips Its going to be JPR's 382. I dont plan on spraying it anytime soon (hopefully never if I can maintain my senses), but there is always a chance that down the line I could decide that I need to go faster and dump a mid sized shot into it. Stick with 30#?
Whats the easiest way to get the PCM reflashed?

Re: Need fuel system/setup tips 24# SVO injectors in our LS1 engines (having 58psi fuel pressure) will flow 29.25#/hr. This should be plenty for your 382.
BUT like the other gentleman said, if you are going to use nitrous or add a supercharger, you will need bigger fuel injectors.
