4G swap in a 3000gt?

Congrats again buddy..!

I love your no hype thread progress

Wheels look great....are those 275's out back? Looks like it could use more rubber..

Well here's a little hype since I can't wait to build a longblock with a twinscroll T4!!..BTW, decided not to f around. TS T4 is by far the best mix of spool and top end; gives great streetability and should help stalling the auto.

Yeah. 275 in back. Needs more low. Engine swap definitely saved some weight so it's riding a little higher front and rear.

edit: I think the rears look bigger/wider in person. After relooking at those pics, they look like they are tucked as much as stock, but that's definitely not the case.

Oil leak? What oil leak? That's just sweat from all that horse power

Any video. I want to see how my brain would react to this car driving down the road. lol

[familyMAN]

No video driving. It's just an awd auto with no power at this point. Looks just like any other 3S (well not "any" since I have the only double staggered wheel setup on a 3S) until you pop the hood. With an open downpipe, it's hard to tell what kind of engine is in it. Sounds pretty good though.

You aren't having to reconfigure a new output, or add wiring. You are reconfiguring the existing tach input, already wired in to the tach etc, to be an an output inside the AEM.

The ATDSM site explains it in their COP setup info. Ignore all the parts pertaining to wiring the COP, and the CDI(which is 90% of it), and just look at the EMS settings for the tach:

Well, this isn't as easy as I hoped. The rpm pin on 3S ecu is not used at all in AEM 3S ecu. (It is however used as the rpm signal in a DSM ecu). So, I'll have to de-pin and switch it to another low side output. I "think" it should go on a low side ground driver, but since the 3S AEM EMS isn't actually made to send a tach output I have no idea if there are resistors and "crap" that should be in the EMS box to make it work. Waaay out of my knowledge base here.

After seeing it in person, its mind boggling how much space there is in the bay now.

And on a quick ride for just steady cruising it honestly didn't feel much (if any) different from a stock 3S. Car still gets up and moved just fine with this low end proof of concept set up he is running. Whether or not it'll be long term viable and what he wants to do...can't say for sure ATM, but I wouldn't mind doing it in place of a fwd NA honestly.

Did you look inside the 3S version to see if it isn't wired up? It seems like the DSM has it ready, and it just needs to have the settings changed.

It might be easier to use another lowside ground driver from 3S EMS. That 3/2 ratio could be a pain to do outside of the ECU.

Since you used the 3S EMS, what power transistor and coils are you using, 3S or DSM?
