LS2 fuel rail covers w/ non-DBW swap
I just bought these:

And when I set them on my motor I noticed that the passenger side hits the throttle cable bracket, I'm thinking because the Corvette they came off of was drive by wire? Has anyone made these fit without hacking them up too badly? Also, I think I'm gonna have to make a small hole in that same cover fo the dipstick because my dipstick hits the inside of the cover.

Re: LS2 fuel rail covers w/ non-DBW swap
Iansane put the LS2 fuel rail covers on his 5.3 and it looks like he has a cable operated throttle body. Here is the link to his cardomain look on page 2, idk I can't tell from the pictures but im not sure if the covers are just sitting on the engine or if he has actually mounted them.

Re: LS2 fuel rail covers w/ non-DBW swap
I want to say Ian's covers are from an LS1 which would have been a cable driven setup, but I will shoot him a PM to make sure. Thanks!

Re: LS2 fuel rail covers w/ non-DBW swap
LS1 Corvettes weren't cable driven, they were DBW. My understanding is that it's necessary to trim any covers to clear the TB and/or cable when installing them on cable driven motors.

Re: LS2 fuel rail covers w/ non-DBW swap
Pshhh...I don't have a magic wand! If I get a nice weekend this week I will try and test fit them so they will be ready for paint. I'm not installing them for good until they're painted though!

Re: LS2 fuel rail covers w/ non-DBW swap
i have the ls1 ones and can't wait to put them on my carbed motor, hopefully I won't have to hack them "too much" 
those coils area ugly as they come the covers will really set it off I think.

Re: LS2 fuel rail covers w/ non-DBW swap
Guys,
to use the LS2 Fuel rail covers you need:
LS2 Fuel Rails
LS2 Coil packs
This is because the LS2 fuel rail is larger diameter, sits lowered and is slightly different shaped then the LS1 (Shorter injectors on LS2) and the coil packs sit higher on the motor and have tall ball end studs the covers hook onto. I found this out the hard way when i bought a set to fit on a LS1
You need to cut a slot in the covers to allow the throttle cable bracket to sit into it, like this (you can kinda see)

Re: LS2 fuel rail covers w/ non-DBW swap
Hmm that's interesting. I'm gonna try and make it work anyways, I think I can do it, especially if what Pocket said about the coils being the same between the trucks and LS2's is true. I'll let you know what I find out, when I have time to work on it. I've even got a spare LS1 intake and fuel rail to mock it up with.

LS1 intake/fuel rail are the reason the covers wont work.
Their fitable, but alot of cutting & hacking need to be done

I bet you if you used duct tape you could make them work, or at least make them look like they are mounted

Actually the thought did cross my mind...it sure would make changing the oil a lot easier than if they were mounted haha!

Re: LS2 fuel rail covers w/ non-DBW swap
I dont know about duct tape...but some strips of good quality, strategically placed velcro could probably get the job done. There's always a way to make them fit.
You gotta clearance for the throttle lever even with the LS1 covers. IF you have a FAST 90mm or bigger intake, you'll need to also make the little cut outs that go against the intake bigger since the runners are bigger. Then depending on your heater hoses, you might have to cut in the back of the passenger side too.
Here are my LS1 covers on my old car.



On a side note...I cant wait to fill in the lettering and customize those covers. Seeing corvette bothers me.

Re: LS2 fuel rail covers w/ non-DBW swap
Haha..that was from the TPI motor. I had a vac gauge hooked up, and kept collapsing the lines I was trying to use. So I used a silicone line...in green, because thats all I had. It was hidden on the other car, and since I never hooked it up to the LS, it was all pulled out. Its gone now, and the gauge is still not hooked up because Im too lazy to run the stiff nylon line to a vac source.
I have to say..I have a TON of spectre and other importish crap laying around. I used to be a manager at autozone, and when the returned goods were "manager dispose", the went into the dumpster by way of my trunk. The stuff comes in handy sometimes, no matter how goofy it looks. I cant tell you how many cigarette plugs Ive used off of non-working neons and other stupid blinking lights hahaha.

Re: LS2 fuel rail covers w/ non-DBW swap
I think my passenger side cover will end up looking a lot like yours, hacked up in the back side. My heater hoses run a very similar route.

Re: LS2 fuel rail covers w/ non-DBW swap
You shoudlnt use the phrase "hacked up"... Trimmed to fit sounds much better!
Im actually thinking about getting another cover. And Bending some coolant lines out of copper tubing and hard mounting them to the chassis rail. Then make the connection at the heater core and water pump with short sections of rubber hose. Not sure what that would do to my coolant flow, but it should work ok. Should avoid having to cut the cover, and should allow for a cleaner install. Sort of like the 4th gens had with their alum tubing.
You can make em fit... Ide like to see a dry run with them just laying in place to see how they look. I sorta like em better than the LS1 style that I have...

Re: LS2 fuel rail covers w/ non-DBW swap
Id like to make some heater core tubes from bent conduit, but after fitting the HVAC box and seeing how little room there is behind the pass cyl head, I went with the standard hoses over top of everything. If the heatercore could be clocked differently and the outlets not directly over the engine, maybe rotated under the HVAC box it would be an excellent way to clean up the engine bay
I have to pull my heatercore this week, Ill see if it will fit in any other direction with new holes in the firewall

Re: LS2 fuel rail covers w/ non-DBW swap
I think I may be able to "trim to fit" the old heater core hard line from my car in a way that would be more visually appealing than my two over-the-top hoses. I think I can somehow make two short rubber hoses at the water pump end, into the hard line mounted on the frame, use a pipe bender to **** the line towards the heater core at the rear end of it, and use my 90* hoses to go into the heater core. I will see what I can come up with in the following weeks. Its about to be car show season and I really don't want to screw around too much, that and I am still persuing a full-time job, so my car money is all dried up haha

Re: LS2 fuel rail covers w/ non-DBW swap
Im thinking some short radius 90's off the heater core. Get them turned down as soon as possible coming off the firewall. Then ill custom bend some tubing to run it tight to the HVAC box, and down to the classis rail. From there, Ill run to the heater control valve, which Ill have to connect with rubber couplings. Then run the tubing over towards the water pump. Probably just bring them close, and then connect with some rubber elbows.
Im thinking about using copper. easiest to work with, dirt cheap, and I can just spray it flat black to make it blend in.
Just not much room over by my HVAC box. And Im afraid to put too many bends in the tubing because I dont know how well that has to flow. My gut tells me it'll be ok no matter what though.
If I didnt have that heater control valve, Ide be using russle 90* fittings off the heater core, and running stainless -an line.

Re: LS2 fuel rail covers w/ non-DBW swap
Whoa, what the fudge? What fittings could I use if I went with Russell ones and stainless line? I think I like that idea better, and my setup doesn't use a heater control valve...*excited*

Re: LS2 fuel rail covers w/ non-DBW swap
Haha didnt get that far.. But I imagine you'd have to use compression fittings on the heater core. You can probably get something for the water pump side of things. I think you'd have to tap the water pump after you got the standard fittings out.
I guess you can weld/braze threads onto where you need em...but Russels has a TON of stuff. Something has to be able to work.
It was just a brain storming session though..I never dug into it.

Re: LS2 fuel rail covers w/ non-DBW swap
Im going to look at my LS1 hoses tomorrow...IF I still have them. They are similar to the LT1 hoses..except at the water pump end.

Eh... actually...acording to the ebay add, these are for a 2000. I dont remember them being this funky, but if this is what I have, I dont think they'll do what I want. Back to the drawing board...
