My Detailed 2jz-gte/240sx swap

[Steve2jz240]

OH YEAH!!!

LOL!!! its goin down very soon guys very soon!!!!

[ronin083]

nice

[edward644]

welcome back. my 2jz swap is done. thanks to this guy...

[Steve2jz240]

why not just send your wiring out?

For the little money it costs to have a 100% working product. is worth it. Let alone if you "try" it and it fails your out time and money. then you have to pay someone to track down your problems.

Tech2 motorsportsDr. Tweak (Pheonix tuning)uhm Rukus racing does wiring too.as do a few others now.

$500?ish from Tech2.

the whole point is to be able to save the $500 and put it towards something else.. The wiring REALLY IS NOT DIFFICULT. if you can find a switch 12v and a constant 12v source on you 240 you can get the motor to run for free. I can start the motor on the ground without it even being in the car. Stay tuned im not far just working on a few things around the shop so i can have a few days to work only on the 240.

how's it coming along?? its been a minute i figured you would be done by now!!

you are the prophet, and bringer of twin turbo 6 cylinder hotness.

take your time.

EDIT:: thats the first thing you'll have to show us, is how to get a constant 12Vfrom an S chassis car... and why that even matters!?

once you give a 5 year old explanation of the most basic/ minimum involved.

our adult brains will grasp the rest

not everyone is mad of money. thanks to him i didnt pay $550 and i got to put it into something else in the car.

what year is your zenki

[ayeesha_240z]

Hi,

I am from Houston, TX. got 1995 240 sx SE and thinking for last three months for 2jz engine swap. I think i'll wait a lil to see these thread and i'll go for it. I am so excited to see a 2jz on S14.

Mr. Steve ALL THE BEST AND WISH YOU A VERY GOOD LUCK.I was searching through google and found your thread. I read it from 1 to 5 pages and then register myself to see how ur project will end. To me you are like an inspiration. Hogh five for you. My budget is also 6 K. So please provide as much information you can to help us. Take care.

[azienbabyboi]

damn alot of good find huh. i want to see that 2jz running! awsome engines

Just a little update...

ITS IN!!!.........

Mounts are custom and easy to make and the engine sits extremely low. it could go a tad bit further back but im happy with the result.

Late Night Update:Well I found some time today to tidy up the engine bay a little bit, and install the fuel system, run the SS fuel lines, and install the IM and the fuel pressure regulator! lot of fun and i think it came out ok. here are some pics of the progress (turbo is not installed just mocked up to kind of see where to route the IC piping)a must have...Sard....Unlike any of my previous swaps, im going to utilize the stock body harness connectors.. Basically what we need is to find a 12v switched (which means is "hot" only when the key is in the "on" position.. And to do this we use......ThisNow when the battery is hooked up, and the key is on, check with what i showed you above to see which pins are "hot" on each plug. If the pins u check are hot when the key is on, and not hot when its not than you have found your 12v switch! (switched on when the key is on)

Right now im working on an s14 but the s13 is not much different at all. Still the same principal.I found that the white colored plug at the top of the three connectors is ALWAYS hot and we probably want to use that for our alternator.. (we will venture into that later) on the black plug that is on the very bottom we found that the wires colored White/red stripe and Green are our 12v switched which one of these are actually directly related to the dash board electrical system... Now, we found our 12v switch what do we do now?? Well, if you want to do it right you will want to wire in a few relays for what we are going to use these 12v switched for...On the 2j motor there is an additional plug for the ECU that doesn't come with the stock harness (ill take a picture tommorrow) our switched power need to go into this missing plug that you can actually get from any str8 6 cylinder lexus from a junkyard, or just pm me and cause i have a bunch. and if you like to learn about relays click here. http://www.youtube.com/watch?v=By8tbu4AqtA Goofy lookin nigga but he's knows his relays and its a great starting point if dont know s***... I know you guys are gonna have some questions so feel free to ask because ill be happy to help. This is just phase 1 of the wiring ill get more into detail with pictures and stuff the further i get. Thanks

here's another decent explanation on how relays work..http://www.youtube.com/watch?v...lated

[Steve2jz240]

A 12volt (v) constant is a power from the battery that is CONSTANT (always live even when the car is off) this is needed for the ECU memory.. have you ever noticed that when you disconnect the battery in some cars and connect it back the car doesnt start up the same. maybe shakes a little or runs rich for a short period of time?? Well the computer (ECU) learns different values, like fuel trim, cold start, yadda yadda yadda. for the computer to retain these "memories" the computer has to have a 12v constant source... A switch 12v source is just about the same its just that its only hot when the car is in the on position.. For the 2j we'll need a switch (12v) to the computer also we'll need one for the ignitor, coils,injectors, map sensor (which is only 5 or less volts but the voltage is controled by the computer) injectors, VSV's and a few other engine components.. It sounds like a lot but there are actually 2 wires on one of the 2j's engine harness plug (The other big gray plug not the one that goes into the ecu) Later i'll show you guys the exact plug and what wires to pull out and give 12v's to.. i highly recommend using a relay and maybe even a aftermarket fuse box i'll show you guys later. I usually I like to have the engine running independently of the car if that makes any sense.. i Make my own fuse/relay box so that diagnosing a problem for who ever im doing this swap for wont be a pain in the a**. they can just go a see if they blew a fuse or whatever, besides having the 2j harness mixed in with the ka harness plus its easier for me to explain in person how it works and what goes where. more info and pics to explain what the hell im talking about later...

[ayeesha_240z]

Wow.............it looks great. I am so excited. Whenever your car will be ready plzzzzzzzzzz let us know. I might come from houston to visit that...............i cant stop thinking about it.

Thanks for sharing your build.

[Kalypso]

watched the video, very helpful! the second vid link is busted tho.

OK so 12v source... that's comes on with the ignition.

ignite the engine outside the bay, and alsocustom fuse box, a plus.

how do you send fuel, when its on the floor? step by step starting a 2J on the floor would be a better way so explain things. because if you can do it on the floor, you can put it in any car.

to start the motor on the ground you would basically need some 18g wire, a battery and a bucket of gas and a fuel pump with fuel lines... first you find the feed and return line on the engine which both are located on/near the intake manifold.. hook one line to the fuel pump and the other end to the feed line under the intake. Second you hook you return line onto the fuel pressure regulator and run that line back to you bucket of gas. Ground the fuel pump to the battery/engine and test the + wire on the pump to the + side of the battery the pump should run..

Next on the big block connector on the harness there are a 3 wires you need to pull out and hook to a 12v source (the battery) 1 is the switch for the starter and the other 2 are for the ignitor, coils, injectors(ill show which later). the ones for the ignitor go to the battery positive side. the switch for the starter only touches the positive side of the batter to crank the engine over. next we plug the ecu to the harness, a few more wires from the 2nd plug on the ecu go to the battery (which ill show later) GROUND THE ENGINE which means hook the negative side of the battery directly to the engine via a battery cable. Everything is live now so all you have to do touch the starter switch wire to the battery and vvvvrrroooommmm. be careful because the motor isn't mounted to anything and can tip or whatever... Better yet, ill post up some pictures in a few to make things a little easier to understand

[edward644]

hey bro did you find out how to wire the A/C for the car?

[ayeesha_240z]

Hi,

I got a quick question is that a 2jz VVTI two way twin turbo engine?

[Kalypso]

hey bro did you find out how to wire the A/C for the car?

...worry about starting the motor first then come back and ask that.

google!?

you are my hero this explanation is everything that's needed... you did it Steve thank you.

3 wires for coils ignition and ect... would be useful, this is all we need.

[edward644]

yeah bro.... i already started mine up. all i got left is A/c

[Steve2jz240]

well here is a video for those who are still reading and watchin... http://www.youtube.com/watch?v=djwEr_VW9WA

[Ramonesfreak2010]

^Sick engine, sick ride, sick video. lol Keep it up.

[Flicktitty]

wtf? 87 octane?

[Philipio]

Ever get your speedo working?

[nevertheless]

holy balls!

[Steve2jz240]

wtf? 87 octane?

thats the old gas that was still in the tank.

[Steve2jz240]

Ever get your speedo working?

this company makes a device you can screw into where the stock r154 cable comes out of the transmission and it turns the signal from a cable to a electrical signal but i lost the bookmark to that site.. i may just use the dakota interface thingy in conjunction with the ABS sensor

[Kalypso]

goddamn steve... you pump these cars out!

[Steve2jz240]

goddamn steve... you pump these cars out!

haha. the streets and the track need em'..

[edward644]

man its sick i like it.

[RMerritts]

definitely a bad a** ride, might have even swayed me away from my ls1 swap to a 2jz swap.... thats pretty tough considering Im a hardcore chevy guy.

[cole d]

I'm new to nissan always loved the 2jz I've been torn between LSx or 2JZ after seeing that video I'm leaning towards 2jz. So you guys that are doing the swap are buying the engine and transmission separate?
