'91 RS LS1/4L60E swap w/ a few pics... Just figured I'd post a few pics.
Donor car: '99 z28
Recipient car: '91 RS
Mounting - Used Hawks Third Gen LSx swap motor mounts and trans cross brace.
Powertrain - Stock LS1
Induction - 90* Silicone coupler to connect the TB to the MAF, large K&N filter right off the MAF.
Fuel - Used the fuel tank and fuel lines from the donor car, swapped it directly over. Had to trim the rubber filler neck a few inches shorter to get it to fit.
Wiring - Used the stock wiring harness and used the under hood LS1 fuse blocks to power the powertrain.
Cooling - Used the LS1 radiator and dual fans.
Drivetrain - Stock trans, stock converter, swapped over the '99 rear end 3.23/posi/disk brakes to replace the 2.73/non-posi/drum brake equiped stock rear end.
Misc - I deleted the heater/AC box in the fire wall.
Possibly unique procedures:
-I took on of the TC trottle cable mid lines from the donor car (ASR equipped) and moddified the adjustment section to be the exact length needed to use it as a non-TC throttle cable. Fits perfectly.
-Instead of wiring up the stock gauges to work, I installed the 4th gen gauges in the 3rd gen dash and they all work flawlessly. Had to trim the cluster gauge cavity a little to fit them, but now they sit in their nicely.
I have more pics if needed...

If you have anymore pics of that guage cluster in the car i would love to see them. I know your dash is slightly different from mine but i would like to make that work with mine. Alot cheaper than a speedo converter box for my cable speedo or adapting to the old style tail housing. thanks.

Not the prettiest, but it works great... If you have anymore pics of that guage cluster in the car i would love to see them.
