300zx Knock/Detonation sensor bypass.

300zx Knock/Detonation sensor delete.

How to delete knock sensor VG30DETT Z32 300ZX

A question I see quite regularly is where is my knock/detonation sensor located & what do I do if I get a code 34 from my ecu.

The answer is quite easy you can buy a new knock sensor and relocate it for easy access in the future or the easiest and cheapest option is to bypass it.

The reason for this is unless you have your motor out or want to pull it out the knock sensor is basically impossible to get at. As shown in the picture 1 below it is located under the plenum.

First step locate your knock sensor plug as shown in Picture 2 it is located close to the firewall and roughly the centre of the engine bay the wiring will go down the back of the plenum & unplug the sensor.

Second step You will need a 1M Ohm resistor as shown in picture 3. You can purchase a 20 pack off ebay for around $2 and will probably be able to get one from an Auto shop for under $5. You will need to bend the ends to the required shape & plug it into the ecu side of the plug not the side that goes back to the plug as shown in picture 4.

Third step start up your car and you should no longer have an issue.

I hear a lot of people ask is it reliable and does it work. Yes I have done this on a drift car that is pushed to its limits every time it is driven & never had an issue with it being bypassed.

300zx Lock

The Nissan 300zx is not known for its good turning circle or massive amounts of lock.

I managed to get some pretty decent lock out of our silver T Top drift car with very basic mods which would of cost less then $100

Will be trying a few more ideas with our slicktop drift car to see how much Lock I can get out of it without using custom knuckles etc.

Slick Top Clutch Fitment

Have finally managed to fit the clutch in my slicktop drift car.

Decided to go with a ceramic 6 puck sprung clutch main reason being because I have used them for competition drifting and they seem to be very responsive and reliable.

Will post up a detailed step by step instructions on how to remove and replace 300zx gearbox and clutch in the next few days.

The Beginning

I’ve decided to start a blog following my journey into the world of drift car racing and all that comes with it. I chose to drift Nissan 300zx’s for various reason (which I will get into later) but mainly because they are one of my favourite cars. I’m fairly new to the drifting scene but certainly not to the mechanical side of things. I do all my own work on my drift cars and I will documenting it so that it might help someone when they work on their car. The Nissan 300zx (twin turbo) is a very powerful car but there is little to no room in the engine bay. This makes quick repairs very difficult and being a race car it’s important that I simplify the design to suit my needs all while ensuring I get the most power from it.

My Cars –

I currently have two drift cars (but 5 300zx’s currently).

The first is a silver twin turbo Z32 2+2 that hasn’t had a lot of mechanical modifications done to it. That being said, it still has atleast 400hp. The interior has been fully stripped out only leaving the seats and top part of dash in the car. Many deletes have been performed such as egr, AIV, Carbon canister and rear hicas to simplify things and also to remove unnecessary weight .

 

 

The second is a slick top Z32 fairlady 2+0 that I have rebuilt completely. I have considerably modified this car to suit my needs on the track. I’m only a few weeks away from finally starting it up again after many months of hard work rebuilding it. It will be vinyl wrapped, tuned and given a run on a Dyno as soon as I’m done putting it back together so I’m very excited about that. I’m hoping that this will have 500+hp output to begin with.

I’ve had to do so many things to my cars – mechanically that I have videoed or documented it so others may use as a reference. These cars can be a nightmare to work on and it’s always good to ask for help if unsure.

I’m always happy to give advice to anyone who wants it so just let me know if you have any questions.
