Guest Venture-Z Posted March 12, 2003 Share Posted March 12, 2003 There are no emmissions in Oklahoma, so is there any way to just get rid of all that junk? I saw a picture of an L28, de-smogged with a billit fuel rail, and a polished pleneum. It just looked so clean, and un-cluttered. Another question, can I cut the webbs out of a webbed manifold? Also, is there any difference between a 78' and an 81' FI system Quote Link to comment Share on other sites More sharing options...

z-ya Posted March 19, 2003 Share Posted March 19, 2003 Get yourself a book on Bosch L-Jet fuel injection so you have an understanding of how the system works before you start removing stuff. Off the top of my head, here are a few things you can get rid of: EGR valve charcoal canister I'm sure they may be more items that are not needed. Remeber though, a lot of that stuff is there for cold starting, and drivability. You start removing that, and you'll have a poor running engine. Also, when you see modified FI L6s with not a lot of hoses and or wiring, they are probably running an aftermarket fuel computer. That's what I'm running: http://www.sweetspotproductions.com/psanders/01-28-2002/DSC00013.jpg Pete Quote Link to comment Share on other sites More sharing options...
Guest polarity Posted March 19, 2003 Share Posted March 19, 2003 since this came up. What type of system are you running. about what does a fuel system cost? what are the advantages? Billy Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 19, 2003 Share Posted March 19, 2003 I'm running a WolfEMS v3.0 ( http://www.wolfems.com.au ) computer which controls both fuel and igniton (notice no distributor). The complete setup, including fuel pump, rail, injectors, and pressure regulator cost me around 2K. The main adavantage is programmability. You have precise control over fuel and timing. The kind of control you can't get out of a stock ECU and a mechanical distributor. Most of these types of programmable ECUs have other features like cooling fan control, data logging, and real time displays for debug. It's well worth the investment if you are planning a lot of engine mods, or plan on running a lot of boost. Pete Quote Link to comment Share on other sites More sharing options...
fl327 Posted March 20, 2003 Share Posted March 20, 2003 you can gut everything dang near, but i would keep all the cold start stuff, its nice. i took off the aac on my z, and starting up takes a minute, but thats it, it just takes a little longer to warm up, it still kicks over in the dead of winter like a true EFI. really want to de smog it-CARBS Quote Link to comment Share on other sites More sharing options...
Guest Venture-Z Posted March 21, 2003 Share Posted March 21, 2003 I came across a Holley 390 and manifold. I think im going to run that with an HI-6 system and just scrap the FI. Quote Link to comment Share on other sites More sharing options...
Guest Venture-Z Posted March 21, 2003 Share Posted March 21, 2003 Now I just need to know what wires I can get rid of. Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 21, 2003 Share Posted March 21, 2003 I still think you are better off with the FI, but I like a car that runs well, and one I don't have to screw with. I've had SB Chevys with Holley carbs, and it was always something. Mostly cold starting problems. If you pumped it just right, it would start. If you pumped it too much, it would flood. Anyway, the stock FI system is more than adequate for most modifications (header, exhaust, intake). If you are swapping just to pretty up your engine bay, I dont' think it' s worth it. If you don't think a stock FI system can look nice, take a look at these: http://www.zccne.addr.com/Convention_2001/show/DSC00020.jpg http://www.zccne.addr.com/Convention_2001/show/DSC00060.jpg http://www.zccne.addr.com/Convention_2001/show/Image120.jpg Pete Quote Link to comment Share on other sites More sharing options...
DatsunBoy77 Posted March 23, 2003 Share Posted March 23, 2003 If you are going to go carb, do yourself a favo and use edlebrock. You wont hae the same problems as with a Holley. Holleys need constant rebuilding and adjustments. With an edlebrock it is mostly plug and play, but it is usually good to tweak itfor the best performance. Also they will last years before they need to be rebuilt. I sell both of these products and can tell you it is usually better to go edlebrock. O yeah, i have been wanting to remove some of them damn emmisions crap because i need room for intercooler piping. That carbon canister will be the first to go seeing how i am already missing some smog equiptment from the turbo swap. Quote Link to comment Share on other sites More sharing options...
Guest Venture-Z Posted March 24, 2003 Share Posted March 24, 2003 Those are some really nice pics, but I've had nothing but trouble with my FI system. I bought a set of Weber 34/36s but after reading what a nightmare they where to tune I traded them for a 4-barrel set up complete with a holly 390. I'm going to run that for a while, and if I really hate it I can switch to an Edelbrock. Quote Link to comment Share on other sites More sharing options...
TomoHawk Posted September 23, 2003 Share Posted September 23, 2003 ...That carbon canister will be the first to go... Can you tell us how you will be bypassing it without that 'fuel smell?' Thx. Quote Link to comment Share on other sites More sharing options...
