My 95 SC400 VVTi Swap...

My 95 SC400 VVTi Swap...(Now complete!)
Edit: 7/22/16 - Here is the very first drive. I plan on writing up a long post relating to the swap but for now, I'll leave you guys this:
So a couple of months ago I ran across a deal I just couldn't refuse (less than 500 dollars) on a 99 SC400 shell that had a 90% complete VVTi swap in it. Seeing how my 95 has almost 300K and leaks oil like a Mitsubishi (i.e. every possible location), I decided that it's time to start getting this swap rolling.
I bought my car for $1900 bucks last September, and it needed some cosmetic stuff for the interior (which I had), and the paint is rough in places. I haven;t driven the damn thing in 2 months due to expired VA inspection. Damn exhaust flange is warped and I just don't have the drive to replace it, so i'm going to keep the car parked until it's time to take it to the garage for surgery. The only things I have modified to this point is changing the Pioneer system to the Nakamichi (hey, when you have every piece to do it on the shelf, why not?), and switching over to the 96 keyless entry system (so I could have a remote and trunk pop).
The 99 i bought came with the following:
Engine
Trans
Driveshaft
ECU
Cluster
Keys
Steering Column
All relay/junction boxes/computers and wiring from the fuel tank forward
Fuel tank and pump/sender
Full stock exhaust
So far I have had to buy a shifter (thanks SMWallis, you are my hero), and a throttle cable (weirdest damn DBW system I have ever seen).
At some point i'll buy the 3.26 diff, but it isn't necessary to complete the swap. I also need to buy a correct radiator.
My plan is to essentially is to swap every harness from the kick panels forward into my 95. The fuel pump ecu and sender should plug right in.
So the good thing is, when I purchased the shell, the seller had a battery in it. It fired up first crank and ran like it was brand new. I really like the exhaust on the 98+ car (different resonators), it sounds reserved but not afraid to get vocal if needed.
I'm putting together (slowly but surely) a website that outlines some of the information on the swap. Its at http://sc.pogoism9.com/tiki-index.php. It's a slow process due to real life making me do **** that I don't want to do (i.e. work), but it'll get updated every week or so. Right now there are a few manuals and curcuit information posted out there.
I want to have this whole thing done by the end of August.

Very nice! I always wanted to do this swap. Good luck!
One other thing I was just thinking about, it might be easier if you went standalone. AEM Infinity supports DBW, so it might be something to think about it. You would probably just retain your harness, and add the DBW portion to the ECU. But since you have everything, it should be easier, just more man hours

Picked upa new 99 dash, glove box, console, etc. Also got a 99 column (w/ 3 spoke wheel!), to match the airbags I bought (for 50 bucks each I might add). Also ordered my "project re-seal" engine kit. Just want to change all seals, timing belt, water pump, etc. Work should start in a coupe of weeks with the teardown of the 95 front end for the rewire. Heres a parting shot of the car as it exists now. I just put a tiny bit if gas in her to make the drive of shame to the garage this week.

I was pretty damn excited that the old girl fired up first try. As far as I know, there aren't many 92-97s riding around with a vvti in them (not sure why, other than immobilizer).
It was funny. I put the exhaust from the 99 donor car on it, because mine had several holes in it. I could barely hear the motor from behind, and what little I *did* hear was coming from the front because the hood was off.

As far as I know, the early electric throttle systems used a cable to actuate an accelerator position sensor, which in turn fired the throttle motor. There is a failsafe built in though. If the ecu senses a problem with the electric throttle it cuts power to the motor and the throttle plate is actuated via the cable, but the butterfly will only open approx 30%.
