2JZGTE Swapped S-Chassis thread

I'm really not too nervous extending the harness and making it work in my S13, but I was happy to pay a professional to do this for me. The only thing I could imagine is the throttle by wire issue but I'm still not 100% clear which 1JZ VVTI's have this feature

Still waiting on a response from Freed Engineering, haven't tried my luck with Tech2 or Chase Bays as I saw some negative feedback on their harnesses earlier in this thread.

The two options I'm considering are the panicwire that has been mentioned and Tweakd Performance (kind-of leaning towards them as they are fairly local to me). I have talked to panic wire though and they seem very knowledgeable and are very willing to help dial in your setup.

DBW wise, the full drive by wire throttle bodies are labeled "ETCS-i". The other "ETCS" labeled throttle body on 1st gen VVTI's is still a semi-DBW setup, but can be bypassed into a normal throttle body setup much easier once you swap out ECU for an aftermarket setup. The OEM ECU monitors the throttle body and uses it for Traction Control, along with other small adjustments for fuel effeciency. From what I've read, sometimes wide open throttle can be slightly delayed on either TB because of this.

One other note with the ETCS-i throttle body is that the throttle body is essentially the idle control, so if you swap it out, you will need to also swap out the intake manifold for older models with their own IACV. This is interchangeable with either first gen 1jz VVTI (ETCS TB models) or very 1st gen 1JZ (TT setup) intake manifold.

If you intend to keep your OEM ECU and have a ETCS-i throttle body, this is one semi-pricey option:

Thats strange wiring specialties posted this up not too long ago

https://www.facebook.com/12990602369...type=1&theater


I even ask if they would do a pro 1jz vvti they said 'it coming soon"

[bmaddock]

Hey thanks guys for clarifying the DBW and harness options. This thread has cleared up so much for me.

That is odd Wiring Specialties would post that photo, especially considering they told me yesterday through email that they weren't interested.

Technically you can do this, however if you want to use the OEM ECU, the ECU will go into "limp" mode if it doesnt receive feedback from the TB. You can't even unplug the sensors without it doing this. The only product I've seen that allows you to bypass is the AMUSE ETCS controller but it is pretty hard to find.

No matter what, unfortunately it does get pricey just to get a regular cable setup. I'm using an AEM V2 and I still plan on trying to swap out the throttle body and intake manifold from a 1st gen 1JZ to get full control as I don't believe the AEM is capable of idle control via TB and I have the newest gen TB.

I've only ever had these mounts on my swap but they are great. The engine torques the slightest bit under WOT revving but there doesn't seem to be a lot of vibration transferred. I'm running open down pipe so it loud inside the car no matter what. Freed swears by them so I went ahead on got them (not from him though).

Alright, so I just finished installing this bad boys.

Everything works as intended but, I do not know where to get the tach
signal from.
Any of you guys know and can guide me in the right direction?

BTW, Big thanks to Broadfield for building me this sweet cluster.
Need great looking gauges and custom work?
Give the man a call.
Awesome person/seller.

hey guys, posting from the uk here.

my 1jz s14 I've built has always had a temp issue when drifting, it's struggling to keep cool with both electric fans switched on (push fans)

bonnet and front bumper off are the only way of keeping constant temps under 100 degrease Celsius

I've done this lately after seeing the viscous unit done on a few jz swapped sbodies

first of all, I got myself a gktech s14, these are excellent fans

then I had a milling machine chop drill out the Toyota pcd into the Nissan sr20 gktech fan, they also took a little off the Toyota unit




so I chopped out the front end, my friend paul is a tig welder and came and pretty much made all the front end tube

moved the rad forward so that it's against the vehicle front frame lower parts (cross member in the uk)



with moving the rad forward though the rad hose wouldn't reach

he made up an extension pipe



basically I'm now waiting to get the car back out and go drifing again, I'm desperate to know how much of a difference it'll actually make

FAN SHROUD/COWLING will be on shortly, it's currently sat in my mate's workshop

Once you have the shroud on it, it will probably work like a dream.

Tach signal wire is on the small 4 pin plug of the ignitor.

also the gauges look great.

[kalel540]

I found this picture:


I am assuming the signal comes from plug A but, what pin is it?
Thanks in advance.

Its pin 1 or 3 on plug a. Let me check

EDIT: It seems to be pin 1 (IG-) from what I can find on the interwebs.

Id check mine but the car is in storage haha.

Anyone know how this http://zilvia.net/f/showthread.php?t=544928 air intake kit fits with s14 vvti 2jzgte stock turbo setup?

1) Does hood close ok?
2) Do you have to move fusebox on s14?

If you look closely on this pic, http://i1092.photobucket.com/albums/...psac237f32.jpg , there are 2 rubber hose barbs without the hoses connected. One is on the intake, and one is on the hot pipe. I wonder if they had to leave those off for fitment, or if they just forgot to put them back?

In the process of a 2JZ-GTE VVTi in my S13. My motor was missing the Throttle Position Sensor, and the vendor is out of stock currently. I know a US TPS will work, but I am not sure which one. Either

a) 1995 Supra GTE TPS
or
b) any VVTi TPS from a newer model IS300, GS300 (2JZGE)

Can anyone confirm with one is interchangeable? FYI the coil pack wires are the same on US VVTi cars.

I know the ETCS motor thing is compatible but might not be 100% drop in. IIRC you might have to take take off part of the cam and flip it upside down to match the IS300 one. AS for TPS, that should be interchangable. I have both an IS300 and 2jzgte vvti which helps for these situations. Let me know if you want any pics or anything.

Those barbs are just the hoses between the Hot side and intake and the stock BOV goes in between. I am sure they just forgot to put them back on, that shouldn't affect fitment.

As for the fuse box, looks like it would fit with some massaging

Did you ever get your car running?

What would be awesome would be if you could tell me the part # that is on the 2JZ VVTi TPS! I should be able to easily cross reference that TPS online and order a new one.

[240sxrb30]

That is tight tolerance on that fan setup. Shows me I can't use the clutch fan setup.

Went and looked at my VVTi in the garage, hope this helps

Picked up a few more parts for my swap, and my AEM infinity should be here in a week or so. Getting close now to finally getting this thing running.

[jbjslambert]

who is need of getting their DBW (drive by wire) VVTi throttle body to work like a regular cable operated one?

this will only work with guys that have a standalone ECU and do not want to use the motor operation at all...

I will need at least 10 people to make bulk CNC run.

i would be! around how much these will run?

i have a new 2jzgte T4 twin scroll manifold dual gated for 38mm tials
price is 900 + shipping + paypal ImageUploadedByTapatalk1421373219.471375.jpgImageUploadedByTapatalk1421373270.083692.jpg

1jz VVTI or 2jz VVTI? And same question as above, about how much? I'm interested..

[S13project]

also interested for 1jz vvti

[jbjslambert]

I am hoping to keep the cost down, the first one is already made (mine of course)lol, labor was free on that one. I am talking with a CNC machinist about running a batch based off of mine. initial setup will cost, but i am sure i can get it down to 50-60ish shipped. depends how many is made in the first batch.

like i said, this will only be to make the throttle body cable driven. gears will be removed and tossed. I will later produce a kit for OEM ECU guys



3 guys interested so far

[Mister.E]

Can anyone identify this sensor for me please? It's on a 1JZ-GTE non-VVTi intake manifold.

if I'm not mistaken, I believe it's the intake air temp sensor

[Drink&Drift]

For those of you with cooling problems, my setup works flawlessly and never goes over 200 degrees, even under hard driving and hot weather. so i figured i would share and provide some tips. i also highly recommend running a power steering cooler, the steering is much more responsive and smoother. you'd be surprised how high the fluid temps get without one under normal driving. same with an oil cooler, its almost a must.

[AS240]

Does anyone know what the alternator amperage output is on a 2jzgte vvti from Jzs161 Aristo? I've been searching and can't find a definitive answer.
