Painted And finally the final install after countless trails.

Upper plenum and throttle body adapter and flange welded together Final cleanup for paint

Throttle body adapter built Smoothed out to look like one piece.

Throttle body had to be on a angle so it wouldnt hit the distributor. Removing the rough sandcast off lower and upper parts of the intake Getting a rough idea for the measurements. My CAD design of what needed to be built for the thottle body so it wouldnt hit the distributor.

Fitting the gas and diesel together Welded Grinding the welds smooth Winter of '07-'08 the real work begins Fitting

I wanted to try something different that many have not done. I found 1 fast z's page on the Maxima's LD intake on a Z, and I decided I am going to do that. I found a LD intake on ebay and won it for $15. I had a 280zxt intake laying around that I would use for the intake flange, injector bungs, and the throttle body flange. Its taken 4 months of on and off again work, but its together and will be running this week. What I started with My zxt manifold cut

The 300 is at my parents, and is my brothers... I live 6 miles away.. I keep forgetting to bring a 280 flywheel over there... But this question in void now. Turns out the scaring on the flywheel was just a oil residue... So it came right off and the flywheel turned nice. So thanks anyway.

Did some research, found nothing but more questions, and part numbers. Asked on Zcar.com, but I seem to have attracted the douche bag purists that just want to tell me how that question is stupid. Will a 80's 280zx non turbo flywheel bolt up to a 80's 300zx non turbo crank? If not, does anyone know the dimension or bolt pattern difference? The reason I ask is because I am helping my brother convert his 88 300zx from a auto to a manual. He bought a donor car and was told engine and trans are in good shape. Well the flywheel has a nice gash around the inner part of where the clutch rides, dont know if turning it will get it out. But I have a pile of 280zx flywheels that I am not using... Thus the question.

Picture of the internal regulated alternator jumper wires Red to Red, and Blue to Blue I have the diode taped off, but it is in the yellow with blue striped wire I believe.

You have to unplug the external regulator and jumper some pins and install a diode on the return charge wire. I will take some pictures tomorrow of my setup.

Yes, it will be a throttle cable now. I am glad I kept all that linkage on the throttle body for the 240sx. But as Clifton said, I dont know of any power increases, I am looking for a different style, and maybe throttle response. But if there are any power increases, that would be nice.

Bottom half is all welded, sand cast is pretty much off both halves, a bit rough now, awaiting final sanding. Just waiting to get off my lazy ass and get the throttle body flange welded on the top half. Throttle body will be mounted TPS up

Thanks.

Anybody use this on a 81zxt engine with a z31 eccs upgrade?? It would just be used for a little while until I get my NIStune.

Ive been watching some GTS's on ebay and they have been going for $3 to $4 grand lately. Jason and Scott, I would love to go dragging... I want to come out there before the weather gets nasty. Maybe I will have more boost by then and I wont look so slow against you guys

WOW!!! that thing hauls! Rode in it and I got a little nervous when he hit 3rd and was flooring it around a long sweeper corner. Raced him later that night and he was at 11psi, and me at 12 on a stock zxt engine and turbo, and I felt like I was standing still. Then we went again this time him at 20psi and I felt like I was going backward!! So Scott, you convinced me to go turbo... Convinced me to get a RB. Now I cant wait till 2009! Maybe we should buy 2 at the same time

For a relay you will have to run a constant power, ground, switched power, and a signal. I am assuming you know what prongs on the relay that you are using do what? Constant - Usually from the + side of the battery. Switched power - Ignition switch or another source of switched power. Because you are doing a Turbo swap with the turbo wire harness, you would run this to the Blue/red wire that runs out of the ECU. This will control your pump correctly and it will automatically shut the pump off after 5 seconds when the car is not running. Ground - anywhere on the chassis or - post on the battery Signal - this wire sends the signal of +12v to what ever your relay is going to run. So this wire will connect to the power side of your fuel pump. No need to cut the whole harness. Be sure you have the power wire that goes to the fuel pump.

Sticky?

SUCCESS!!

Thank you

Good! Glad to see you got it to work.

are the 280zx flanges that go into he diff compatible with a 300zx diff?

That little black thing as you call it is the trigger. A NA car has a seperate ignition system totally different than the turbo's. The turbos ignition is in the ecu its self. How it works; The CAS reads a wheel on the crank, or a chopper wheel in the distributor depending on your year. The ECU reads the signal coming from the CAS. To fire the spark to the coil, the ecu grounds itself sending a signal to the trigger to fire the coil. N/A have transistor ignitions

Well changed out the fpr to a z31 turbo regualator, up's the fuel pressure about 5 to 10 psi, and that seemed to make the difference. pulls good, never goes into the red at WOT, so hopefully it was just a fuel pressure thing this time.
