Engine was off 02 with 50k miles which included all
LS1 accessories power steering pump, TB, etc

prepping the engine bay.


I started off by removing most of the wiring. Me and my brother have already experienced a ls1 swap in the past his his 3rd gen.

After hours of working on his car I gained a bit more experience and my set up was a bit more organized..

My engine was far gone I was ready to start prepping the engine bay for a better quality look.

My previous set up consisted of a cammed 350 mated with McLeod bell, mn12 GTO tranny and 4th gen rear differential

My intentions is to build a reliable 80s performance vehicle with the LSx drivability performance, yet fuel efficient, with modern interior and able to say I built this car.

I used esi data output for all the schematics for the 4th gen wiring.

Im attempting to run the evap and a fully functional cluster.

The process took a few months the only problem I came across was using a ls2 bell housing and finding the right starter. After researching the least expensive starter was the OEM Mitsubishi starter for lsx goats.

I purchased the ls1 with a k member and brake set up off ls1tech member.
As well as the fuel tank and dashboard.

Small appliances were supplied by the local parts store
All the fuel fittings and adapters were from others online or summit

Al work was done by myself with help of my close friends
And soon enough need some exhaust work for the y pipe

i started off with dissembling the old dash . Cutting grinding and bending metal for a test fit on the new dash .


Soon moved on to the 4th gen vents these fall right on top of the 3rd gen unit.. Modded and cut for future usage.






After painting the engine bay I left it plain and simple.
Main red wires were to control the ignition supply.
the instrumental work was done with extending wiring and merging the 4th gen cluster plug mostly color matched

i used two power distrubution blocks. from the battery as the main 12v source and power with ignition.



before with tpi wiring

after with Spohn motor mounts in place.


using the ls7 clutch kit




Moved back to the engine and worked on the smaller components
Used autometer adaptor fitting for the individual gauges for my oil pressure and water temp. aside from the cluster .


Used a summit radiator and hoses from AutoZone to run the cooler routed back to the power steering pump unit fuel rail fittings and evap controls etc,



Here I used 90* swivel fittings from the local speed shop
As well as compressor fitting which I used to shorten the 4th gen fuel feed line

Over view of the 4th gen fuel tank


I extended the wiring from the evap canister module, and the sending unit up to the dash .a whole lot of wiring.
Re worked on the quick disconnects and added fuel hose with some good clamps. These fuel lines were routed up by the rear area united to the fuel filter and hard lines to the front on the engine bay.

I used the walbro fuel pump a few mods. And this is what it looked like with a opening in the cargo area for easy access sealed up pretty good.

Cut 2.5 inches off the filler neck to clear the fuel door


The sending unit harness extended sodered and united to the control plugs




Once I received my harness from lt1wiring . Couldn’t be easier.
Pictures below everything was test fit and included with the obd2 port, fan relay, fuel pump relay and extended 2.5 feet for easy installation




Just scaring u guys a bit.. jk a bit unorganized but wire loom can take care of this.

The rest of the wires on my cluster plug consisted off the signal off the harness vss, oil temp

You're only 100# off. Here's one recent thread that has info for a couple of LS-swap cars. It seems that the ballpark is around 3300#.

I'm really curious to find out how my heavy pig GTA is going to turn out...
