Wiring a 280zx turbo motor into a 240z

[Shiin]

It's a question asked a lot and I'm sorry for asking again, but I had the thought of buying a used 2001 Celica gts or using the money to dump into the Z. I went back and forth on this for a day and thought that I can't leave my Z behind after all the work I put into finding it.

So Any here done this motor swap:confused: What else is required beside and long block motor including turbo ecu wiring harness and tranny. Is it hard to wire up? i has planning on buying the motor and go on vacation for a week off of work and put the engine in, but I want to adress most of the problems before I deside to stripe my car apart.

Thanks for your help:confused:

-ps. Sorry for the long rambling post.

I haven't done this conversion but I've done similar things.

This will sound obvious, but it won't be hard to wire up if you know where everthing goes. By that I mean if you are starting with a bundle of wires in a box marked 'wiring loom' from the wreckers you are screwed from the start.

The best way is to pull the stuff out of the donor car yourself. Work slowly and takes lots of notes, pictures, and tag everything you can. What's even better is if you can buy the donor car so you can have it there as a constant source of bits while you are doing your conversion. You can always drop it back to the wreckers later!

Thanks for the advise Rob.

when I'm ready to do the swap these tips will come in handy for wiring it up.

I have done this conversion and it is very easy! I also have the wiring color codes for the fuel injection harness. If you are still interested e-mail me...huetters@bellsouth.net

TURBO DATSUNS RULE !!

the stock harness is pretty simple to hook up, very simple especially because you dont need any of the emissions stuff, which deletes a whole lot of vacum and electrical right off the bat.

heres too options:

buy a junky 280zxt and beat the crap out of it for a while, and study that harness well

or

go to the junkyard, with the SOLE intention of grabbing that harness complete, even the stuff you will throw away anyway, get ready to rip a dashboard to shreds and at the same time be very patient with those connectors, saving those little rings that snug everything.

heres a breakdown of what you WILL need.

ecu

afm

tps

distributor

ignition transistor

boost sensor

head temp sensor

knock sensor

vehicle speed sensor (VSS)

this harness comes in one big pigtail:

-geen and tan relays, green is efi, the tan one i dont know, havent had any problems with it.

-fusible links

-alternator wiring

-injector harness

-tps plug

-distributor plug

-three or four efi grounds to the manifold

-afm plug

-unplug ecu and put somewhere nice

-leads to positive and negative on battery, not the cables themselves but the leads factory has wired to battery to harness

-leads to ignition transistor

-VSS is in the steering column, tiime to bash that dashboard in.

take your time and find the way to get all this stuff out of the car without ripping the harness at all, its not that hard, it does get tedious and may take you a couple hours.

I would also add not to grab the 81 turbo harness, it uses a crank angle sensor mounted on the crank pulley, and its a little harder to use than 82-83-which have the sensor in the distributor. dont trip if it takes you a long time to understand. The first time i took a harness it took me four and a half hours, i will now take me an hour or so to do a better job than i did the first time. good luck.

I have dont the swap in my 76 280z..

you dont need the vss or the boost sensor.... you need everything else.

also get the j-pipe, the oil cooler and lines
