Hey Steve I remember you now, awesome I know at least 1 person.

Don't have pics of my update from tonight, But I heat Wraped the Down pipe on the exhaust and shot it with some High Temp Ceramic to stop the heat wrap going all crappy.

Then spent some time sanding through some surface rust spots around the window.

Horn still isn't working I need to find some sort of Grease or paste that's electrically conductive. Its hard to explain but the pin that pushes against it seems to be touching enough yet when i trace it with a multi meter there is no circuit.

Anybody else had this problem ?

Edit> ok so not getting pics was lazy, Yay no more rust around the window. Oh and if you do ever use header wrap put on some gloves and tape them over your sleeves I got fibreglass shit everywhere but manged not to get itchy from being prepared.





also did this just for fun

make sure its clean 1st of all, failing that, make sure the spring pushing it down still has some tension in it

Wow Been Busy on the car since the last update.

* Exhaust Re Fitting
* Wide band sensor fitted into Exhaust
* Power Wires and fuses run through firewall for data logger
* DIY wheel alignment done
( close enough to get me to a proper laser alignment place )

* Fittied a Flash new K&N high performance/race oil filter and dropped the running in oil with cam additives for some mineral 15/40 to finish running in before a switch to synthetic Ams Oil

Wired up my new Ignitor module, the old one still works fine but i don't want miss fires under boost in 5th gear at high rpm when something could easily be ruined from it.

This car has also been fitted with a brand new crank angle sensor and other "prone to failure" on old cars kind of stuff

Bled the clutch up & bypassed the stupid clutch damper with a 280zx brake hose, clutch still feels a bit light considering its a heavy duty one. Must investigate this further.

Picked up my 3pc rims, i love them they are pretty dam 80's bad ass.

Center bore needs to be opened up to fit so here is a pic with them held up to the car instead & other misc pics.

tomorrow is day 1 of Road tuning.










To anybody thinking tuning an EFI system is going to be cheap or easy

"cos its a computer and it can just sort itself out"

is way off the mark, it seems you need so much crap to do it.

*Laptop
*ECU which connects to laptop ( http://www.nistune.com" onclick="window.open(this.href);return false; is what I used in my original ECU )
*Data Logging unit
*wide band Sensor for Data unit
*Display gauge so the driver can see the air fuel mix ( and back the hell of if it lean spikes or something )

and the hardest part of all is somebody who knows what they are doing.

I don't but my very experienced engineer/fabricator/expert on many things has tuned a lot of cars and is doing this with me.




As you can see here I have added a proper spare tire as the space saver requires pumped up by a tiny air compressor to save on space aka supercar style
