No, I have a wiring harness thats made for a 240 with an RB so it will pretty much be plug and play. should make for an easy time, lol

I would never put that cover over this motor, to each their own, but i do not like them at all so it will be staying the way that is. haha

[jdizzy204]

why did you put the RB in before painting the bay?

[TwoHarbors240]

To make sure the solid mounts i bought fit up to everything right, and the firewall needed to be beaten in so the starter would fit. it would be dumb to paint it and then realize everything will go wrong, lol, ya know?

[TwoHarbors240]

Another update, its getting there

[TwoHarbors240]

Did quite a bit today, some more pics!!

[junn]

very nice

looking good

[TwoHarbors240]

got the downpipe, dump tube, wastegate, throttle body, and some other little shit buttoned up as well. didnt figure it was enough of an update for pics so... yeah

[higgzy]

are you mounting the heater hoses back up? also how close to the firewall is the engine?

[TwoHarbors240]

yeah it gets pretty cold up here so i am going to be hooking them back up. I would say there is well over an inch in between the head and the firewall, fits excellent

[TwoHarbors240]

Ok, so im having some trouble with the route of the fuel lines/system. I have an aeromotive fuel pressure regulator with 2 inlet ports and a return port on the bottom. If anyone could shed some light on the situation that would be great. thanks

[TwoHarbors240]

Everything is starting to fall into place now, got the radiator in and the hoses hooked up, mounted the fans on to it, got the intercooler mounted and the piping ran, most of the main harness is hooked up, also got the gauge lines ran through the firewall.

Still need to mount the regulator and lines, hook up the lower harness, do some vacuum lines, and run the wires for the wideband. other than that its getting real close!

Here are some more pics from the update

[TwoHarbors240]

ok, so on the main RB harness I have, there is a plug that goes up under the dash on the passenger side. This harness was made for an 89-90 240sx (with a white plug) and my car is a 91-94 (with a brown plug). Does anyone know where I can get a diagram for both so I can rewire it correctly? Seeing as how the colors dont match up..

[omgRWDgoodness!]

Glad to see I'm not the only one that'll be running dual Mishimotos as pushers with my RB Make sure to cover how you wire those up!

[TwoHarbors240]

Ha, yeah I had to run them on the front of the radiator. They wouldnt even fit in between the motor and radiator if i wanted them to, i tried..

[dmp316]

[TwoHarbors240]

[TwoHarbors240]

Okay, so Im pretty sure that everything is wired up as it should be, but my lights, gauge cluster, power windows, locks, climate control, and cd player dont work. Does anyone have any incite on the situation? Thanks

[Hiighboost2]

Looks awesome! Nice build man!

[TwoHarbors240]

does anyone have any idea whats going on with the wiring?? the car starts, the fans work, the wideband works... but i have no power windows, lights, cd player, climate control. nothing.

If you find out what the problem is with the wiring lmk, i'm gonna be doing a very similar swap soon. Are you using a premade Wiring Specialties conversion harness? What motor mounts and motor swap mounts did you use? Sick thread bud, i'm bookmarking this bissh

[alexanderig]

car looked clean to begin with but looks great now. and motor is looking beastly. i didnt see it but how much power are you looking to make? and after 4 years it looks like your patience is paying off

[TwoHarbors240]

it makes 440 whp on 110 right now, looking for similar numbers on 93 this year, if it gets retuned. Would like to see 500 in the future

[higgzy]

nice to see it going man! hope you sort out the wiring

Keep the updates coming!

[TwoHarbors240]

Still havent figured out what the deal with the wiring is, im stumped so it still sits..ugh

And after about 5lbs of boost it starts to cut out and backfire, so im guessing that its gonna need a tune before it comes out anyways.

[StryfeS13]

Check your 75A fuse in the fusebox..I blew mine out once when re-installing my motor and the exact thing happened to me.

I guess I grounded the alt wrong or something.

[SkylinePowas13]

this is awsome man ,keep up the good work

[boyou2]

you put PU engine mounts?

You should change it, it's very stiff, my car is shaking at idle :/

[TwoHarbors240]

Solid mounts are a good thing, thats what i wanted. it moved around a lot before
