Man I'm impressed, you were able to maintain your cool with all that neighborly gunfire going on in background, while you were explaining the tbi 2 LS1 swap conversion on your 88 Chevy truck. Good video minus the gunfire.
I found out how important fuel pump year to year is. I got 95 Caprice figured 92 at junkyard would work. No TBI has less pressure than tpi. I broke down bought right pump worked perfect. Vats on LS swap kill injectors. So computer needs vats deleted and rear o2 sencers.
1. Did you have to upgrade your fuel pump ? And do you have any part numbers for that? 2. What Trans are you running and did you have to make new cross members ? Thanks for the video. Think you did a great job
I use a fuel pump for a 97-up Vortec truck. I do not have the part number, I just told the counter guy I needed a pump for a 1998 Chevy C1500. I was running the donor's 4L60. I will be upgrading to a 4L80. I used the stock 88 C1500 crossmember. It's back about a half inch or so. I bolted it to the trans an ddrilled new holes where it landed on the frame.
Nice truck, im building a 1991 fleetside. Im going through my tbi truck engine bay harness and what did you keep from it? Maybe a video showing what you have left from the tbi harness? Thanks
Did you use the stock 4L60E? I’m fixing to do the swap on my 1995 Tahoe. I dumped 2 grand building my trans last year, so I’d like to know how you made it work.
Can you make a video of how you got the transmission shifter lever to work? Or explain how ? Doing a ls swap on a 89 silverado and i cant seem to figure out how to get the transmission shift lever figured out .
Waiting on my 88 to get delivered I bought out of state, planning on diving into it fast for a swap. Was there any rubber lines anywhere on your system that needed replaced? This setup still working good for you with no issues with the higher pressure from an LS system? Great video and very helpful.
First off nice build, I’m doing the same thing but mine is a z71. Not sure if some asked this already but how did the tbi sensors like the temp sensor hook up to the ls harness. Thanks
Start off by not doing anything with the tbi harness, until everything is wired. Just go in the stuck tbi harness and find your gauge wires. Depending on your LS harness you'll either reuse the tbi harness connectors or clip them for the LS harness. I highly recomend buying a prebuilt harness specific to your truck.
HAMMETT SPEED & CYCLE thanks so much for your response, I really appreciate it. Do you have any suggestions on who or where I should get a pre built harness for my 88 from. And who did your ecm. Thanks a lot.
Just curious, I have a 91. Noticed that my ECU has an input wire coming from the A/C that kicks up the engine idle when it’s cycling itself. I know you omitted the air conditioning but I’d like to keep mine...I guess I should try and obtain an LS ECU diagram, determine whichever one it is on the connector and tap into that? This will be my first one as well. I believe it’s just a single wire.
When I had my harness built the guy left a wire for me to connect to. I'm not sure yet how all that is connected. This swap was done on non existent budget, and ac wasnt priorty.
Agree, that’s a a/c request wire, on 91 harness, thats all u need, then hook it to a/c request pin from ls harness ,, Ls pcm will command the a/c now, in conjunction eith low/ high pressure switch located on a/c lines,,,
Real good video. Do you have air and do you know what the ls1 came out of? Got an ole 93 at I'm going to put an ls in soon. Couple more weeks of overtime and I ought to have enough money and the time to make it happen. Not my daily just an old truck my dad had for along time. He was going to junk it. Everyone calls it old Red. I just couldn't let it go to the scrap yard. Going to make it better than new. Thanks for the video
The generic swivel fittings you show are those for the fuel lines? does it take 2 of them if so? I didnt notice but was the AC compressor left in place or was it removed? Thanks looks great
Where did you connect the switch ignition for the fuse and relays ? Because Idk where to get the the switch 12v because when testing it drops to 6v. So I need a location to where to connect it to
Nice video. I plan on doing a ls swap in my 78 regal but dont know where to start. I know i want to get the motor and transmission out of a 2001-2006 suburban or tahoe. What all would i need to do?
Find a donor truck. Avalanches are great because of the Avalanche only parts. Take the engine trans and anythi,g drivetrain or wiring related, part out the rest of the Avalanche.

If you use the Car Shop mounts they drop in. The trans cross member is pushed back about a half inch. I just drilled new holes in the frame. A lot of the other mounts have slotted holes so you can move the engine where ever you need it.
@@LonH77 I've read like I'm sure you have the update and downs to the nv3500. I just plan on freshing up the motor and probably a decent cam to spice it up while I got it apart. I still wanna use the truck for work like pulling the camper and what not so I'm not sure what kind of cam would be suitable yet. 350/400hp would be nice and the 5spd should handle that but anything more sounds like it's just a matter of time before it has a catastrophic failure.
As for as the clutch goes I'm do t gonna do anything radical maybe a stage 1 or something slightly better than stock. I'm going for a more relaxed clutching work, we did a stage 2 or one a buddys truck thinking it was cool shit but I didnt care for the sudden grab when trying to take off or riding the clutch a little bit on a hill or stoplight.
$2500 doing it yourself. $1500 for donor vehicle. $250-$500 wire harness, $100-$250 computer flashing, $200-$500 exhaust, $200-$500 fuel system (depending on what you start with). Now subtract whatever you sale any of the parts from donor vehicle.
Factory truck manifolds. Everything fit great, no chopping or modifying. I pulled it out of the Avalanche and it dropped right into the GMT400 chassis.
