My S13 "Silvia" RB20 project! (w/ lots of pics!)

[supersayianjim]

you should had just sent youre harness to carl.. its not too late though..

[HIGHFIV5]

Imma email you a wiring guide i made.I have no idea if its correct yet as i havent tested it but i took my sweet a** time looking and comparingthe guides and then tracing wires back to the pins to verify what they were.Its just for the upper harness so far but maybe you can compare what yougot and maybe add a thing to my guide even or maybe something willbe different. Its gonna be a wiring guide for dummies pre much to make it aseasy to follow as possible. Hope it helps!

well i got it on the car(needs a little modification) started with this..

and after banging it for a while( the wastegate pipe was in the way).then took it to my good friend at nissan(the first time it didnt turn out right. 2nd time looked better.

the o2 sensor pits perfectlyhttp://i495.photobucket.com/al...4.jpg

and finally in the car. there is proper clearance to the downpipe even though it is shorter than stock

there is a very noticable difference between this and the stocker. the turbo does spool up faster. i know you want to get it started(so do i) but this is

doable with the engine in the car. and you will be satisfied...

Nice, looks good. Clears the steering rod even more than w/ the stock elbow

Okay, so i talked to a local rb20 owner here from northwestnissans.com. And he said its probably my ecu. I turned my car on to look at the ecu lights when i noticed that only the red light is on. I remember on my previous swaps that the red and green should be on. So it could be a bad ecu. Luckily he has a spare that he can sell to me if thats the issue. It has to be... seriously... please be it... lol

[HIGHFIV5]

Ahhh. I emailed yeh that guide btw.Perhaps your ECU isnt getting grounded properlyor not getting power through the proper wires?Its possible.Hope a new ECU helps!Itd be alot easier than finding a wiring issue!

Hey yea, i double checked everything. It all matches up perfectly... And i did more research on my ecu. Some came with one red light so its normal. I did a diagnostic test and it came out 55. So everything is good to the ecu...

Weird thing is i took out one of the plugs and didnt smell any fuel. WTF, i know i hooked up the fuel pump correctly. I can just look at my pics lol

[HIGHFIV5]

Woot thats good news for my guide than!Im trying to make it impossible to have any confusionwhen it comes to the wiring guide.hmm weird... well at least now youve narrowed down your problem,and can start troubleshooting.Watch it be something retardedly simple like the Fuel Pump relaynot being plugged in HAHA.Good luck!

[locoluna825]

silvia aero.....??

[Seanzyyy]

please please PLEASE get this b**** running! everytime you try, record it. i'm pretty sure i speak for everyone when i say the first startup needs to be viewed by all of us.

does the engine turn over? do you have the green relays plugged in?

[CA18Magic]

Yup relays are plugged in. Even switched them with my sisters fuse box haha. Engine turns over but thats it. Did some investigating starting w/ fuel first. Pulled a plug out and didnt smell and fuel after a bit of cranking. Tried to listen for the fuel pump to prime. But didnt hear anything. So i pulled it out to check it. At first there was hesitation when i hooked it up to a battery. So i re did the connections and this time soldered it and shrink wrapped it. Now i know the fuel pump is good, pulled the fuel line at the motor to have fuel spew out everywhere. So good sign that its working for sure. I was double checking to make sure i had my fuel lines hooked up right. And from write ups for fpr installs it look'd fine. I then traced the hard fuel line to the rail... and look what i found... Looks like the line was pinched some how probably during shipping.

So, now i'm left with that issue... and a possible igniter issue. I have the spare z32 that i'm going to wire up using carl h and booztd's writeup zerothread/251366

But yea... i'll have vids. As soon as i get this up and running.

[Chris28]

Well at least you know what it is, though that kinda sucks. I'm sure you can fix it, probably don't have to buy a new rail. Take it somewhere and see if they can braze a new line on, or just cut it right before the kink and after the 90 degree bend and put some rubber fuel hose on there. If there is enough hard line before the kink you'll be able to get hose and a clamp on there no problem.

Good luck with the rest of it, car looks so sick. I'm throughly impressed.

[locoluna825]

wow, hope you can get it running soon.

chukis????

Hey thanks man. I'll continue to post onto this thread even through paint process haha. Thats the fun part. Getting on the right track to getting it running.. man, whole other story.

As for the kink, that was the first fix that came to mind. But its super close to the fuel rail itself. So if i were to cut the kinked part out, there wouldnt be enough room to put a hose and clamp securely onto it... I could cut it right before the bend, and try to straighten out some of the tubing just enough to put a hose there. I dunno. I'll look at it closer tomorrow.

So i re-pinned the clips to fit the z32 igniter. Still no luck with getting some kind of start up. Even some hesitation would be nice....

[Chris28]

Yeah man, I'd be surprised if you got it to fire at all with that kink. What material is the fuel rail? If you can weld to it (probable) then just cut it off flush with the rail itself, cut about 1/2" off the good straight part of the feed hard line, and weld that onto the rail where you cut off the kinked portion. All you'd have to do at that point is get a 1/2" longer section of hose to cover the part of hard line you cut out.

You've probably thought of that, but I want to see this thing run haha.

lol, yea ME TOO!!! I've even though about cutting it flush... then tapping it with a 1/8 npt barb fitting like this And just just attach the fuel line directly to it!

[Chris28]

Do it! Can you find that part locally? I hate waiting on the little things.

[CA18Magic]

Do it! Can you find that part locally? I hate waiting on the little things.

I'm gonna try. There's a domestic tuner shop local to here. But unlike all the import race shops around here... these guys actually have stuff in stock. A lot of fittings, nitrous stuff etc etc. So i'll stop there tomorrow.

Just for a confidence boost... you think thats keeping it from starting? I would atleast think it would studder right? Unless its so backed up that no pressure is getting to the injectors. AAghhh i hope thats it. Ive dont everything else. And i know my wiring is straight.

[Chris28]

I'm 99% sure it's that. Practically no fuel is getting to the injectors so in turn only 1/6 of that fuel is actually going into each combustion chamber. Since you pulled the plugs and didn't smell fuel I'm willing to bet that's your problem.

If not it could be injector wiring, if you're bored I'd at least make sure the injectors are getting power.

[locoluna825]

noone answer meees...

[supersayianjim]

HEY CA i had the same problem when i tried to start up my rb at first. and it was........the fuel lines were on backwards... fix youre kink and swap the lines going to the fuel rail with the other return line and see if it works!!!

[CA18Magic]

If you have time, take a pic of how you have yours set up? I have the lower line going into the fuel filter... and the hose from there going to the fuel line that brings it to where the kink is... and the return hose is connected to the line closest to the oem fpr.

[CA18Magic]

GOOD NEWS! SHE LIVES!!!! Fixed my fuel rail problem... but still didn't start up?! I was literally pooping my pants. haha, so continued to do more research.. and found some stuff on youtube of a guy having the same issues. After 4 vid uploads he did he finally figured it out. ANd it was something that even i didnt read anywhere!

So the one thing that was keeping her from waking up, was connecting pin 16 eccs wire to the two orange wires on the 2 green relays. He had an automatic too.. so maybe its the only thing needed to be done differently? Either way, i'm happy! Video will be at the end like promised! Keep in mind, not everything is hooked up yet, and the throttle cable isnt bolted down yet either.

Orange wires on both relays to orange wire pin 16Fuel rail fix.And for the VIDEO! http://www.youtube.com/watch?v=AB1eu_EEH78

[Wongger]

Congratz duudee!!!

I know its kinda early and you just want to drive it how it is for awhile, but...

Future plans?

Btw thanks for the intercooler link!!

[lilrussian]

Man this is sick!Congrats on starting her!I remember the problems with the RB20 in my friends 240sxBut in the end it's all worth it ehh?

[HIGHFIV5]

Glad to hear yeh have it running man!Cant wait to fire mine up! Kinda weird tho..on my harnessthe orange wire is already connected to those twoin the green relays...Wonder why yours wasnt?

[troskinatior]

Yeah, it started.

I can't wait for more updates

[Noxy]

Hmm. This is useful info since my car was an automatic... Congratulations on getting her going! Hope she stays that way!

[CA18Magic]

So, this is my first vid of it running and idling good. Still havent timed it, soon though.
