Andy (Xylemer) glad to see you on the board.

There's no need to be humble, when you've put together one bad-ass car.

Great job, and I look forward to seeing it completed this week.

Monday Night, Andy and I worked til 2 a.m. @ Southern Imports to get the motor running.

When we attached the AEM EMS ECU, it started first crank with the AEM supplied base map.

I was very impressed with how simple the box is to use, and I want to thank Sean Morris for taking my phone call late at night to confirm we had the configurations setup accurately.

We still have lots of work left to be done, and these are, by no means, final images.

As you can see, there are aftermarket gauge sensors that need to be hooked up. The boost controller is not installed, the intake for the turbo still needs to be ordered, downpipe has not been fabricated, and the upper intercooler piping has not been polished.

But the motor runs, and that's a success in itself.

Yesterday, I transported the car to Texas, and will be finishing up the car here.

Once again, thanks to Andy Vaughn @ Southern Imports in Murfreesboro, TN. He, by himself, built 95% of the car that you are fixing to see. He is a amazing fabricator, engine builder, and friend. Thanks again Andy!

Here are the images and the start-up video:

Makes me wish i went with a 26 man.. so hot!!!

are you running a twin scroll turbo as well?
You might of already mentioned what turbo it is. but i didnt find that info.

Also, what engine management did you go with?

EDIT: GT4088R....... Thats twin scroll isn't it?
I am cretin that i want a GT35R or GT40R twin scroll

but first i want to get my stand alone (i hope this week)

So, have you done any tuning on the sucker? When does full boost hit? Congrats man, absolutely amazing.....

RB26powered74z · 06-19-2007, 06:56 PM

Thats one top notch job there...... props!!

We now have everything finished with the motor minus the installation of the new 24x12x4 intercooler that arrived today.

I want to thanks Matchless Performance (Addison, TX) for the fabrication of the downpipe, which came out better than I would have ever imagined. The welds are amazing, and extremely clean.

Here are the latest images:

While I still have the interior to finish off, here are the completed exterior shots.

This 240SX has been four years in the making, with 30 corporate sponsors on the stage II build.

I want to give a special thanks to Andy Vaughn @ Southern Imports, and Chris Hamilton (tuner) for their work on the vehicle.

ch1873857 · 06-25-2007, 02:34 AM

took awhile to take it all in. its clean as shit. wouldnt change a thing. but the wheels are meh..but i realize the corporate sponsorship thing. definately a car to be driven

Just hadn't bled it when those photos were taken. But it's been bled now, and I should have some dyno graphs to post soon.
