Long @ LT Motorwerks sent over an N54 car today for me to help tune. It's a Nissan RHD 240z with an N54 single turbo retrofit! Absolutely the craziest thing I've ever seen.









Unfortunately after closer inspection I found a few little things that have to be addressed before we can fully tune it. Can you spot the three problems in this picture?

[Snertz]

Neat! MAP sensor, O2 sensor, and TB vacuum port?

Haha was wondering what they did with the O2s when the first pic popped up on IG.

[viperware]

Clean. I wonder if an N54 would fit in the Gozer.

[Pure Turbos]

Ha! That's neat!

-O2's not per bank and a mile away from the motor
-CP coupler is going to pop off
-Pos lug on the alternator should be capped
-Tmap is hanging out in the engine bay!

[Payam @ BMS]

I remember before I joined BMS Me and Anthony were supposed to work on it. He never brought it to us though. Glad its actually working!!

Haha yes the three obvious problems I was talking about was the o2 sensors being so far downstream, not seperated by bank, and the TMAP sensor not mounted in the chargepipe. But the chargepipe does look loose and there are various other minor things. Another problem we ran in today was there is no OBDII port.

This is absolutely insane. Thanks for sharing.

Oh, ya. He's going to need one of those...

Nice! )

Terry, please share if single bank O2 issue will be solved

Lol, i wonder how they change spark plug on sixth cylinder

[samstryker]

1. Throttle body connector is unpugged
2. Charge pipe needs map sensor bung tapped into it
3. No throttle body bypass air hose

Sick project! I'm so happy to see the n54 being swapped into different chassis

All that work and no standalone EMS?

That is a great point

[Tony@VargasTurboTech]

Pretty clean for what it is. Needs a lot more than tuning help thats for sure. Shouldn't it be a requirement, that the person performing the engine swap at least know a little bit about the motor he is swapping in? Good luck with that one, looks like a can of worms to get working properly.

[Terry @ BMS]

Whoever made the turbo manifold and pipe did a nice job but missed some basic steps in terms of the O2 placement and such. Don't think they knew much about N54s in particular though. Also wish they would have gone with a PTE compressor. But at the end of the day even with 600whp or whatever this car will be stupid fast.

[cebrailbakan]

Shocked

[JuniorB]

Now I know I can do my n54 swap! Terry, does that even run? Doesn't that need a n54 ecu,or standalone to run the direct injection?? Insane piece! Keep us updated with the progress!

[Terry @ BMS]

Yes seems to run normally using a factory DME and harness they cut up a bit. They also put in the gateway and E series N54 dash modules. The fuel gauge doesn't work and the DME throws like 20 faults for various missing things it would normally have out on the CANbus like stability control, SRS, etc, but car runs and drives fine as far as I can tell. Once the o2 sensors and TMAP are sorted we'll see if it makes any power.

Very cool, must've been fun getting that up the driveway.

[THE BEAST]

Can you share drivetrain set up ? What tranny, driveshaft, rearend, gear ratio, and rear suspension set up plz.
