1977 Turbo LQ4 280z Build

Recommended Posts

Now that it has cooled down, progress on the car has been made.

 

I scored some free simpson 5 point harnesses for free. basically brand new still,

It was time for the first fitment test. she fit in there almost perfectly. of course the old trans mounts were in the way.

The engine fit perfectly as soon as the trans mounts were cut out of the transmission tunnel. The shifter even sticks perfectly through the stock hole.

Also, before it was too late, i decided on buying a new turbo. I upgraded to an 88mm turbo. The smaller turbo had an turbine wheel too small for the 6.0, so i figured it was best to upgrade while i can.

before engine mounts were made, i decided that none of the stock fuel system would be reused. The stock tank is being replaced by a fuel cell. the stock fuel lines and pump were no longer going to be used either. So i tore out the entire fuel system, including where the tank vents to. The worst part of this was separating the fuel lines from the brake line that goes to the rear passenger brake and then cutting the fuel lines into pieces, trying to remove the lines from around the rear suspension.

Engine mounts are made and supporting the engine.Huge thanks to my dad doing the fab work!An angled plate was welded to the frame rail to reinforce the frame rails, but 4 holes in each frame rail was drilled in order to make room for a threaded nut that was welded on the plates before being welded to the frame rail so that the engine mounts could still be removable. with the plate welded to the frame rail, another plate, similar to the one welded to the frame rail, was welded to the post of the engine mount, also with 4 holes drilled in the same locations as the other plate. with this, the mount will be able to bolt and unbolt from the car.look at the picture for reference. With attaching the engine mount to the frame rail, the original mounts on the K member will be cut off so there is more room for the turbo exhaust to exit.

The original plan was to use the stock exhaust manifolds, but the only way to get them to fit was to cut some of the manifold off and weld pipe to it, which is not what i wanted to do for cosmetic reasons. I looked into up and forward headers, which also can be used for down and forward headers, but i was unsure how well they hug the block and did not want to be stuck with a pair of headers that would also not fit. Instead, exhaust manifolds and the rest of the hot side is just about ready to fab up. I have my water pump temporarily installed and am waiting on the fbody alternator bracket to come in so fab work can begin on the exhaust. Mild steel is the choice of material as it is cheaper, plus it is very rarely humid out here, but the exhaust will be ceramic coated anyways to prevent corrosion and for cosmetic reasons.

Before a trans mount can be made, I ordered bad dog frame rails to reinforce the flimsy OEM ones. To prevent risk of fire, the interior had to come out,

The seatbelts, seats, carpet, center console, and some other odds and ends had to be removed. None of what was removed was being reused. Earlier in the build, I mentioned how rust-free this car was. as i was about to pull the first section of carpet, i was really expecting to see some major rust on the floorboards or something, but luckily, the car has really solid floorboards and it was a huge weight off of my chest!

Wow, it has been a long time.  Over the past almost 3 years. A little has been done to the car since the last update. Ive moved homes and took on 2 kids. The turbo hotside has been fabbed up. I decided to go with a ford 8.8 IRS 31 spline from a ford explorer. I used the t3 backing plates and rear coilovers that came from their q45 doff conversipn so i could run z32TT hubs. Corbeau A4 seats were mounted. The wiring harness was depinned. A fuel cell was put in. I just recently bought fuel line. Pretty much at this point is a domino effect. I need front coilovers and the front 5 lug conversion, brakes all around, wheels and tires (likely just do steelies to be able to drive it around for the time being), exhaust, axles and driveshaft, charge pipes, finish the cooling system, charge piping, and a few odds and ins just to make ot driveable. Still trying to figure out if some flex pipe should be done on the hot side and how to go about supporting the turbo to keep some strain off the pipes.

What manifolds are those? I am in the process of doing a similar swap in a ZX and I am contemplating doing an up-forward thing with modified truck manifolds. Any insight would be much appreciated! Awesome swap by the way.

Theyre home-built manifolds

Awesome build! My car currently has an SBC and the plan is to go LS based in the next few years. Let me know if you're gonna be at any local shows or meetups, I'm new to Las Vegas as of October of 18 (my car is still back in the midwest), would love to see some Z's in the area!
