ZDrifter

The RB motors have Ignitor systems so there is no coil. Thanks for the idea tho. They just have coil packs that plug onto the spark plugs. So it has to go through the ECU but the wires I have tried havent worked.

Alright I have been searching for two days now and have not found the info that I need. I bought a autometer tach for my Z, has rb25 swap. I have the tach adapter along with it. Everything is hooked up and getting power but i read that the yellow/lavender wire from the dash harness is the tach signal. Well i didnt get any signal at all and then I got info from another source that its yellow/red, and still no signal. When I start my car all the needle does is jump and then back to 0 RPM. NEED HELP!!! thanks

Come to think of it, i pulled out my center console during the swap and didnt plug anything back in so if i get what your saying, to complete the power circuit for the hazard/turn signals the switch has to be plugged in? I would be so happy if its as simple as that, I will have to try it in the morning then let you guys know what happens, thanks for the info!

I dont mean to steal this thread or anything but I am having lighting problems aswell. My passenger side headlight wont work, drivers side works both low beam and high beam, and my turn signals arent working. I put a new relay in for the turn signals and still nothing, I also checked the fuses and they are good. I have been messing around with ground wires but cant get them working. I only started having these problems after my RB swap. so if anyone knows exactly where the grounds are or have any other advice that would help out a lot! Thanks

I cant let you know about the rb26 but i have a rb25 in my 280z with full 3" exhaust and FMIC, running stock boost. Its raining here in Oregon and I had the pedal halfway to the floor in 2nd and started burning out like crazy. I have driven it once in the dry and it'll burn all of first and I dont know about second yet cuz I got up to the speed limit. But I did have a street bike coming up on me on the freeway and I was in 5th and I just went about half gas and he didnt pass me until he dropped a gear but I didnt feel like getting any tickets.

Alright got my problems solved thanks to Garage 112 in portland. I got a fuel pressure regulator from them and they tuned it in and set my timing and the car is running amazing. Now its on to start with gauges. I have searched for info on the tach and found some saying that you might get a signal without the tach adapter and I have read that you need the tach adapter, so could anyone give me a firm answer?? thanks

I was actually driving it around all today and its running but really really rich. Likes to backfire and putter a lot and it doesnt want to build very much boost because of that. It seems to run better as I drive it more but still it runs rich so I am thinking definitly a air leak somewhere. But 3" from the turbo back sounds great!!! Hope to get some videos up for you guys soon. I got her to build a little bit of boost and she just took off I couldnt beleive it. but my friends like the 3 foot flame shootin out the back, hopefully I can get her running smooth here so I can see what she can really do.

New Pics check em out tell me what you think.

Thats what I call service.

Sounds like things are going well. My Z is in the shop right now getting intercooler pipes and exhaust, I cant wait to get it back so I can start driving it. Good Luck!

Car is officially in for exhaust and intercooler work hope to get it back by end of next week. pics to come.

Alright so I have a ruff measurement for you. From the original rear mount to the new front tranny mount its around a inch and a half. I put a picture up for you to give you an idea of what i did. Today I will be sprayin all the welds with spray paint to protect from rust, mounting the intercooler and hopefully getting some measurements for pipe. I orderd a Walbro off of ebay but it hasnt arrived yet so im not to happy about that or I would be putting in my new fuel lines, fuel filter, etc. Does anyone have any advice for the coolant lines, its kind of a mess from what i have looked at so far but if i could get some direction that'd be great.

I actually got the tranny finally totally welded in today. I will measure this for you but you have to think about where your motor sits, because if it sits more forward than mine ( cant get much further back then mine) then this wont work. So i will measure that for you tomorrow but just keep that in mind for when you make mounts. I suggest putting the motor and tranny in the car, if you already have the motor mounts made then stick the motor in there bolt it in and put a jack under your tranny. This allows you to jack it up to the exact point where you want it (height and side to side) After you have it where you want it, measure your width between bolts on the rb tranny and then drill your holes in the Z tranny mount. When you have that done bolt your mount on, then use cardboard to make stensels for your mounts. Make one for each mount, 3 of mine ended up being the same and the other had a rounded side for the tranny tunnel to fit in that part that slopes away. After you have them made bolt them onto the mount and tack them onto the tranny tunnel. Remember that the tranny will sink in the mount when you take the jack out so try to compensate for that so you tranny is as level with the rear end as possible, this is important since it will ultimatly put less stress on your drive line. After you have them tacked in then weld away, have atleast two people for this because the tranny tunnel is very thin to weld on so you have to go slow and watch for fire, make sure you pull your carpet away from it and the paint on the interior will bubble and catch on fire if you burn through the tranny tunnel. Just take your time so you dont burn through and use water to quench it. Now that this is said you can understand why i cant give you my measurement unless you used my mounts. But if your confident that your motor is the same placement as mine then i will still give you the measurement. Sounds like you are using mounting plates which is what i was going to do, welding a plate flat to the tranny tunnel then the ears onto that, but plates wont lay flat in the tunnel so its useless, already tried that route haha like i said before i found it best to make stensels for each ear in the tranny tunnel and it turned out that 3 of them were the same and the other more rounded. I will take pictures for you tomorrow and take measurements to help you out, i kno that a lot of 280 guys need this info so whatever you guys need to know ask away and i will help you out the best i can. For new info that i have.....I recieved my intercooler today...drool... i bought it off of ebay from just-intercoolers, they actually have a intercooler sized for a 280z also fits mustang and 300zx. Its made with the inlet and outlet on the right side so you dont have to run the intercooler pipe across infront of the motor if you are using the stock intake. I will be mounting that tomorrow along with fitting pipe. After that it goes into the shop for the exhaust and then I can start driving it while i complete more things on it!

Good call EMWHYROHEN i just switched out my oil pressure sensor today, easy as pie...

I dont know if your talkin about strait up motor parts but the Z lower wiring harness can be adapted to the RB motor with only like 2 changes in connections, its easier using the Z harness but you have to change the relay for the starter and alternator cuz the stock z one will burn up. I havent tried it yet but hopefully tomorrow im going to see if the oil pressure sensor from the Z will fit the RB, if so you can use your stock gauge.

I got the motor around the middle of June and it took my friend and I a weekend to get the motor mounted. The tranny mount took about a week for me to finally figure it out. And yesterday I just got 3" stainless for my exhaust, 2 elbows for my intercooler, and i have 8 feet of 2.5" stainless for the rest of my intercooler piping.

Alright guys i have made a lot of progress so here it is... Tranny problem has been taken care of. I found the easiest way to mount it is to use the stock l28 tranny mount and custom make ears to fit each point in the transmission tunnel, drill holes in the ears bolt them onto the mount and put them up to the tunnel and tack them in. I wish i would have just done this from the start it is by far easier then making a new mount and all that stuff. With that taken care of I am having my driveline made and hopefully will be done monday so I can fit it and hopefully not have to go back to the driveline shop if they screw up. After about 6 hours of work today with wiring and putting oil in the motor it is running. A lot of the stuff is jimmy rigged together just because i wanted to hear it run before my warranty runs out. Definitly sounds good no knocking or anything of the sort so I am releaved. I will try to get pictures up for all of you guys tomorrow as i plan on hooking up heater hoses and tiding up some vaccum lines and fuel lines. I also ordered my Walbro today and should be here middle of this coming week. After that it is getting all the wires nice and then getting intercooler, piping and exhaust.

So I have ran into my first problem, for the tranny mount i made a piece of square tubing to go across the tranny mount place and then two pieces on each end on top for better placing for the mounts on the tranny tunnel. Well my tranny tunnel isnt flat enough to weld/bolt tranny mounts onto it. I have looked at other transmission mounts and noticed there tunnels are a lot straiter then mine so im kind of at a loss. on the passenger side it is perfect for me to place my mount, but on the drivers side its not level at all and only 3 of the 4 corners will lay flat on the tunnel i can take pics tomorrow but does anyone have any ideas for me? im at a loss..... but as for other things wiring starts tomorrow how fun!!! and i got my pay check so its time for more goodies like a driveline, but not until my tranny is bolted up.

Heres the link to my photos, hope you guys enjoy! Thanks for the help J. Let me know what you guys think. Tranny mount coming soon... http://album.hybridz.org/showphoto.php?photo=8105&cat=500
