Out with the stock drivetrain, in with the LS. The 350Z on the lift.

Kolby, KMC Auto

Kolby is the builder behind KMC Auto. He started out working for free at a friend's shop for years, then spent a few more years learning for little pay. He's now been a jet-engine mechanic for 11 years, the last 3 as a lead.

His builds so far:

  • First LS swap: white Nissan 350Z: LS2 and T56, both pulled from an '06 Pontiac GTO
  • Second LS swap: black Nissan 350Z: after the white Z was totaled, its LS was rebuilt fully forged and went into this car
    Walk-around of the black Z, idling.
    • Lower-pressure, lower-temp fluid lines: Aeroquip AQP socketless hose and AN hose ends (e.g. FBL1512 straight, FBL1532 90°, FCN0620 -6 AN hose). Good for up to 300°F and 250 psi, per the builder. Builder tip: simple and works great; use Aeroquip's matching AQP hose with AQP ends.

      Builder's tip: "Be careful with your wheel setup on these brakes. Some wheels won't clear the Akebono calipers. I ordered longer wheel studs so I could run about a 10mm spacer and push the wheels out a little for better wheel-to-caliper clearance."

First LS swap: white Nissan 350Z

The first 350Z Kolby LS-swapped, using the LS2 and T56 from an '06 GTO. After the white Z was totaled, he pulled the LS and rebuilt it with:

  • Eagle forged crank and Eagle forged rods
  • Mahle pistons
  • PRC (Precision Race Components) CNC cylinder heads and a Texas Speed MS2 cam (238/242, .600/.600 lift, 112 LSA as stamped)

Brakes
  • Front 4-piston calipers from a 2019+ Silverado/Sierra 1500
  • Larger front rotors to match (drilled and slotted)
  • Washers used as spacers on the caliper mounts so the 4-piston caliper sits evenly over the rotor (the stock calipers are sliding 2-piston)
  • Extended brake hoses are sometimes recommended for this swap, but the stock hoses worked fine on this truck.

Engine bay finish
  • All engine wiring harness loom redone with Sonoreboom split braided self-wrap wire loom from Amazon (comes in several diameters). Works and looks great, per the builder.
  • Silicone radiator hoses throughout (builder believes from Glenn's Auto Performance)
  • Lower-pressure, lower-temp fluid lines: Aeroquip AQP socketless hose and AN hose ends (e.g. FBL1512 straight, FBL1532 90°, FCN0620 -6 AN hose). Good for up to 300°F and 250 psi, per the builder. Builder tip: simple and works great; use Aeroquip's matching AQP hose with AQP ends.

FAQ

Straight answers

Is the parts list really free?

Yes. No account, no card. You can put in an email if you want updates for your chassis.

Why are some prices marked "est."?

"Listed" means we saw that price on the vendor's page when it was checked (Oct 2026). "Est." is a rough range. Prices move, so always check the link.

Does it do LT swaps too, or just LS?

Both, on one site. Gen V LT engines (L83, L84, L86, L87, LT1, LT4, L8T) are direct injection with a cam-driven high-pressure fuel pump and an E92-family ECM, so the controller, fuel, mounts and harness are a different swap than a Gen III/IV LS. The planner keeps them on their own path and the Build Sheet flags DFM, wet vs dry sump, and 8L90/10L80 TCM matching.

What about the new Gen 6 engines?

GM has announced the Gen 6 L76 5.7, L78 6.6 and LS6 6.7. They're listed as coming soon. We'll add them once real swap parts and controllers exist.

Will it guarantee fitment?

No. It's a planning sheet built from vendor and tech sources. Confirm fitment with the vendor, especially on pans, headers and steering.

What do I get for $24?

The full Build Sheet for one combo: compatibility flags, harness steps, VATS and tune notes, fuel setup, a first-start checklist, and video slots. It's printable and has a link you can come back to.
