Once I found the correct slip yoke I didn't have to shorten my drive shaft either. Wasn't too hard of a swap. Glad I did it even though it blew my budget for the turbo. I'm sure I'm not the only one that a 4l80 swap turned into a 6.0 swap also.

 

OK I'll let u know if I need them.

Hey so I think my stock fuel pump just cropped out can I put my 320lph pump in and be ok? I have a return style fuel system with a stock fpr on the rail.

 

I bought a walbro gss340 for my turbo kit. And my fuel pump just died also. So I installed the walbro without any problems.

 

The pump has two grounds. One is really light gauge. Where do I wire this to?

 

The gss340 is wired to the factory harness. Haven't had a problem with it yet. Only thing I don't like is having to cycle the key twice.

 

change the unit
paint the hot side with heat resisting paint
change any clamp or v-band in the hot side
blow off valve and wastegate tial are awesome and cured my problem with on3 kit
cold side i didn't have any problem with it works great
injectures am running deatchwork 80 ls1 style with holly hi-ram
pumps i ordered them through a garage who did all the work

tranny if it's 4.8 it will take some beating but eventually will die so upgrade is a most

good luck

 

 

Isn't that the truth. I have 3 busted 4l60's laying in the shop that the 5.3 on N2O lay waste to before I wised up and did the 4l80.



OP... looks like you got it finished! Even managed to keep the coolant tank in the factory location. When test fitting mine, I couldn't see the oem tank fitting.

Did you go SD or hide a MAF somewhere? Any problems with the dump tube on the gate heating up the AC compressor? Seems my tube heads right for the compressor?

 

The coolant tank is moved forward over the battery tray with new brackets I made. I haven't really seen anyone else go with this exact placement but I thought it fit well and I retained lots of factory lines with minimal trimming.

I was going to stay maf and try to use my k and n air box/maf set up but I put my overflow there lol. And I had to switch to SD anyways because my charge piping had the bung for the iat sensor so I ordered one from ballenger and used a 2bar map. I saw the issue the dump tube I haven't done anything with it yet because the truck isn't even running yet waiting for my tune. I'm a stainless steel tig welder so extending the pipe a Lil further won't be a challenge for me. But if it's heating Urs up looks like I'll have to do it. Not my daily so idk how much of a issue it's going to be for me. Thanks for the heads up

 

That's a great idea. Never thought about that even. Most everyone seems to use a universal tank and mount it up near the firewall.

You're actually farther ahead than I am at this point. I ended up pulling the kit, putting the longtubes and N2O back on for the rest of the season to get a couple passes in before the track closes for the winter. The wastegate dump tube location just raised a red flag for me. I've got a short list small things like this I'd like to address when the kit goes back on.
