4G swap in a 3000gt?

Pretty simple to understand that 4cyl vs 6cyl simplifies to 2/3

Allegedly simple to understand...This is the forums we're talking bout here..

Thanks. I understand now. Only thing I don't understand is that the AEM is no longer receiving an rpm input but I guess it doesn't matter if it's calculating/generating its own.

It's RPM is calculated from the cam/crank signals. That is the actual RPM of the engine. That RPM input from the PTU should really just mirror the signals sent to the PTU to fire the coils, so the ECU doesn't need that for RPM measurement. The purpose of that RPM feedback is really more for a misfire diagnostic on the OEM ECU. I don't know if AEM actually used the RPM input for that, but I would suspect that they don't.

Another potential plus of using the RPM output from the AEM, is that the tach signal might be smoother when you are on the rev limit or launch limiter.

Are you going to mount the turbo front facing?

Brad thanks again for a possible simple solution. I will definitely try it this weekend and let everyone know.

Audible, not sure on what turbo I'm going to get yet. Forward facing is not really on the list since there isn't a good place to get fresh air without completely redoing my FMIC and radiator setup that current works well. So many good options for turbos to choose from its tough to decide....simple bolt on...red or black...T3 cast mani (couple cost effective options) with an HX40 T3 or something PTE 62/6466...or build or buy a T4 twinscroll and really work an HX40 or various other options.

Need to shake out these little bugs first and get settled in new house. Really considering finding another 2.4 block and building a whole long block that I can just drop-in in a few hours.

long block that I can just drop-in in a few hours.

How nice it must be to be that easy again!

It takes me 3hrs to pull a 6g including removing hood and front bumper and not rushing to set a record. 4g may be a little less since radiator can stay in, alt can stay on and intake mani can stay on. Installation is a little quicker since my mtr mts were made to fit my car so they fit better than the maximal solids I have for the 6g which always fight me a little. Not much difference in time for removing an engine though.

Yeah I guess it only took my 3.5hrs this last go...

We need more, HIGHER RES pictures... I want to see the interior too

Interior will have to wait, but here you go (car hasn't been washed in a couple of months so it's pretty dusty)...........

Hood is on now after some trimming. Angle of engine is perfect. Any more forward tilt and Tcase angle is off and rear of timing belt would be too close. Any less forward tilt and front of timing belt would definitely hit. I "think" I can fit a timing cover, but need to order one to check. That would definitely make me feel better.

May need some solid subframe bushings up front. I watched the engine jiggle a little on a mild shift when I took a lap around the block without a hood and open downpipe. Engine also settled when off hoist on the bushings and I know the mounts aren't moving when at rest. Oh yeah, I guess I forgot to state...........It drives!!!! My Frankenstein'd engine and Frankenstein'd driver side CV Axle works Got it up to 60mph according to log (sorry neighbors!)

Couldn't remember if I posted this. Driver's mount and front roll stop. Still need to make a rear roll stop. Not really a big deal until I start launching it.

Nothing earth shattering, but it works.

Needs tuned badly. Will work on that over the weekend if I get time. Slow as poop with no timing and really rich, but it has instant spool with a 6cm 14b on a 2.4 9:1 with e85..lol. Proof of concept complete. Pilot phase testing over next 3 months, then final stage in 5 months
