1jz 180sx

Recommended Posts

hey guys in the process of building a 1j powered 180sx..atm its getting the fire wall and gear box tunnel cut out and boxed up but just wondering if anyone can wire the motor up or no someone that can? just running stock ecu cheers 0425 379 094

just getting cut out and boxed up so its easier to work with...stock ecu b fine for stock motor a mates jzx90 makes 237kw with stock ecu so thats plenty for a 180

fair enough. i can get to all my bellhousing bolts etc with just a mildly bashed firewall.

 

as for wiring try helps metalworks, i know craig has done them before

yueah not keen on bashed fire wall looks tacky..yeh ill speak to helps..he modded the knuckles and is doing all the mounts n shit

I hope your aiming to use it for the track cos you will have some major traction issues lol

 

As for wiring it up, it not hard at all if your not after aircon / TRC / ABS / and shit like that.

 

 

 

From memory you need to feed ignition to 5 wires,( ECU, Coil, Injectors, etc) then wire up the Alternator wires. then Starter motor +ev (its on the 1jz loom) and its trigger wire and finally a big phat earth wire.

 

 

the rest is sensory outputs to the dash or external gauges.

 

Water temp output is YELLOW-green and its on plug IK1

Oil Temp output is BLACK-yellow and its on plug IK1

Oil Pressure is YELLOW-black and its on plug IK1

Check Engine light is BLUE-yellow and its on plug IK1

Tacho is BLACK and its on plug IK1

Speedo is RED and its on plug IK1 *this same signal goes back to ECU or else it may go into limp mode* or stalls at times.

 

Oh also The speedo and RPM will need to be interfaced with the 180 cluster. i think an ADC (Analog to Digital Converter)

 

its not much. you should be able to use your original Fueling electrical setup. and bypassing the ecu as from memory 1jz powered cars use a fuel pump ecu which cross communicates with the 1JZ ECU.

 

 

 

 

 

Anyways this IS NOT a guide. not at all. but its something to show you that really there is not much too it encase someone tries to charge you an arm and a leg. "which i am sure they will try to"

being such a light car " especially in the rear" its the torque thats gonna make it so much fun =D A ~230rwkw 1jz would probably yield 650Nm or something stupid like that??

 

i was going to go with the 2jz path for my 180 but pulled out of it because to be honest on the streets it will be useless. and that's what i wanted it to be for. i am more of a Hills guys so there is such a thing as too much power :(

LOL you pulled out of a jz conversion due to not having enough grip? You cannot be serious!?

rightio. i had 280rwkw with my 1j s14 and it had heaps of grip...

 

 

 

i guess i should have emphasized "hills" a bit more when talking about traction issues :P

Yeah mate, personally i owned and modified 1jz and 2jz GTE powered cars, and in the heavy chassis they come in it was interesting enough. Throwing that same power into something 400kg lighter and with a very different geometry .. well you don't have to too bright to hindsight the rest.

 

I must say though, i love hills driving and the adrenaline from it all. I only ever owned an import because of that. so chasing big numbers is definitely not a practical or wise choice, nor does chucking giant wheels and rubber in attempt to overcome traction issue's.

 

 

But yeah I don't want to divert this thread any further from the OP queries. =)

I was quoted $1500 from numerous workshops to wire my 1j up into a corona, this included 4s n more (toyota specialists).... all I wanted was for it to start, i dont care about traction control, tacho etc... I knew there wasnt much to connect but I got no idea where to start with the loom as Adelaide jap supplied me with a nice butchered one around the igniter.. Hence why its not wired up now...

If some one wants to do a cashie throw a PM my way... like I said, nothing fancy, just want it to start so I can move it.

I've finished my 1j conversion and had been driving it around for awhile (That said, im taking the engine out right now to rebuild it :

 

Anyway, I used a microtech... the standard computer was going to be a huge problem (mating the nissan wiring system with the toyota loom just wasn't going to happen) for me although a skilled electrician could handle it... be prepared to fork out for it though.

 

The car is SOOOOO much better to drive though... the weight distribution feels better... the power delivery is awesome (even really laggy turbo setups are better - more torque)

 

:D

 

Just make sure your wallet is nice and full...

I drove my car only in the hills and even with all the traction issues it was still far better than my old 'well suited' CA... Control the power with the right foot... The full boost was used rarely in the hills but was well worth it... the torque of the 1jz made it much faster in off and low boost situations...

The only issues you would have with using the original ECU is the speedo / tacho.

 

AS long as the ignition is wired up correctly everything else is ECU regulated and is between the engine and the ECU itself.

 

the check engine light, oil level, etc are all just signals which any digital gauge can read.

 

 

A lazy electrician or a no so wallet happy customer would rather a microtec as its so simple to hook up and they could eliminate so much unwanted stuff easily.

 

 

IMO if you going the microtech way but aren't aiming for anything above 220ish RWKW, your better off with stock ECU. as it will be cheaper. "i think"

 

microtech alone is what $1000? then you need it installed and tuned. ?? i could be way wrong with those prices but yeah..

 

 

as the above post says.. it all comes down to how big your wallet is AND what other components you want running in the car.

Using the microtech allowed me to trim away most of the wiring in the car... in my case, I ended up re-wiring the entire car myself (every single wire removed and only those required were reused)... stock computer was worthless since I have cams, large turbo, large injectors etc etc...

 

That said, yes the stock ecu is cheaper and the driveability with 'bolt on' level of modification is far better with the standard ecu.

 

I should also add... a big factor for the microtech was also that I hate having 'half done jobs' ie... tons of wires running around for an ecu that isnt using them (the toyota loom has lots of crap on it... controls and sensors for things I wouldnt use). When I look at a loom and see 80% useless wires, I look at other options.

 

(I would not recommend a microtech... hard to tune well - neither would I recommend a stock computer :

be aware i think he on hoilday for a week or 3 . then is travelling to WTAC event. so no flaming if he enjoying his rest. :P

 

best place to go for it tho as he has *JZ motors in his blood. crazy fool . he would replace EVER motor known to man with them if the option were his

BIG WORM on this forum is a gun with toyota stuff. has 2 Cressidas with old 1jz and new VVTI 1j's all running factory wiring running perfectly both engineered and rego'd.

 

will be able to conatct him through this forum search BIG WORM will be cheap and done properly is aircraft engineer.

Australia is known as the best country that is showing many forums so that people may interact. Hence I am portentous to follow essay pro reviews that can make everyone more negotiable for materials.
