I'm going to decat the car soon and was after help. Do I go custom straight through or get a S/S cat back off the shelf so to speak and put in decat down pipes. Also there is the query regarding back pressure problems that can be caused by decatting, anyone know more?

Hi guys n girls. Wee question. Back in the day when Custom Car was king and I bought Street Machine Magazine, power mods invariably started with bigger carbs and a lumpy camshaft (usually fast road cam). Nowadays, you get ecu's, air intakes, exhaust upgrades as the way forward. What is the reason for this? Can the standard camshafts be replaced for power versions? Is this a waste of limited funds? Do modern engine management systems not accept the re-profiled cams? Just wondering.

What are the normal fluctuations in the injectors? Do you get any documentation showing this? Are the ones on ebay (for cheaper than norm) the injectors that are not quite so closely matched? Thanks

Have done search but only came up with 3 posts....2 of which were selling them.....seems he had problems getting them to run...but then i think he only had std chip and no fuel controller:- http://www.300zx.co.uk/forums/showthread.php?t=21577&highlight=venom+injectors & http://www.300zx.co.uk/forums/showthread.php?t=42236&highlight=venom As they have never really been mentioned on here im thinking why :confused: Is it coz their poo?

as you have probably all found the jap headlights are pretty useless and you cant see a thing at night!!!! i know you can get the HID conversion kits, but i wondered if there is any "cheap" option to getting something a bit brighter without having to spend into the hundreds (trying to save for a respray......and leather interior.....and some wheels.......and some ICE)? cheers, gaz!

Nice wheels there :cool:

I come in peace...as you can tell from my username i own a Supra, I can hear the groans from some of you already ;) (read some of the original posts) I'm enquiring on behalf of a friend of mine who is very interested in getting a 300ZX. Ideally he would like a manual TT (UK or Jap, LWB or SWB) on a newish plate with lowish mileage for around the £6k mark (don't we all!) is this possible? If so can you point me/him in the right direction and give a bit of infor on them. I've found the http://www.300zx.org.uk/model_variations.htm & http://www.300zx.co.uk/tech/buyingZ.htm which were very helpful. Theres a few of my friends who have a variaty of cars…

Anyone know where is the best place to get new body trims. The ones that go from the front window up over the roof and down the back window. Do they come in sets or seperate pieces. Also has anyone changed these them selves. Chrissyp

Hi guys. How do we test wether an AFM is fooked? Which wire do I look at? What should the voltage be? I think thats what the problem is. It got wet over a week ago and it;s been hesitating badly ever since. Air filter looks ok i.e. dry, splash guard is in place everything. Please help Ivan

when i start my car for the first time in the morning it runs lumpy as hell, if u touch the accelorator the revs drop dramatically, ive also noticed that when this happens i can hear a clicking noise coming from behind the dashboard on the drivers side. It sounds like a switch clicking on and off, this also happens without touching the accelorator the revs jump about and you can hear a clicking. Anyone know what this could be anyhelp please :smash:

These shouts seem a waste of time most of the time but I'll give it a go........... Fri or sat just gone, driving through town. Did make a mental note of the plate but forget now.

As my controller is at the menders i'm running 1mmm boost jets but i've noticed after between 1/2 and 1 hour it jumps into safety boost regular as clockwork now and won't change unless i stop the car then re-start it???? Could it be running too hot problems with fuel or something??? areid@empiredesign.co.uk

Further to my last post where the box changes late from 1 to 2 do you think changing the auto trans oil will improve thingd?? Mick

ok this is probably a really stupid question, but i fitted my grounding kit last night (cheers shrimpy!!! :hyper: ) and i also have airguide slam panels from smithy. i bolted the grounding kit flat to the bulkhead underneath the airguide panel - but this doesnt look right - should the grounding kit be on top?!? cheers peeps!

car starts for 5 min then cuts out and will not start when trying to restart car getting petrol but no spark. can anyone help :headvswal

Hi all I have a question!! Can you use LRP in a Zed that's been DeCatted?? We all know they have to run on Optimax or Super due to the higher protection or Octane Percentage Level but my past mechanical experiance tell's me you should also be able to use LRP if you are catless as it's intended for pre 90 cars (without Cats)and has a Higher octane rating (We all know leaded fuel had a very high octane percentage) But that's Almost unavailable!!! you can still get it at some classic car garage's... The only reason you could not use Leaded was because the lead will make the cat useless within minutes of use. The only thing that i think of that could prevent the use …

I'm wellpissed of as I'm supposed to be going to kings of Europe in 3 week and cars not running, run in, no exhaust system fitted as carn't get to Leons so he can finish it. No speedo (carn't get to Grasshopper so they can finish that) HELP!!!! S.O.S ffs

Guys Who's had what done and whats the pro's con's of either? Ta.

Next on my list of jobs to do is an oil change. I have bought some Mobil 1 5w-50 fully synthetic oil and a new filter. What I want to know is whether it is worthwhile doing an oil change with a 'cheap' mineral oil first to clean the engine out?. I am not sure when the last oil change was done and so I was wondering if doing this intermediate oil change could be beneficial. I understand the potential problems of using a flushing oil and so I thought that using a cheap oil as a 'flush' could provide some of the benefits with none of the nasties. If it is beneficial to do this, how long should I run the cheap oil through the engine, 5 minutes or 500 miles!?!

Went to collect my car from the mot and it wasnt there! The garage said theyd taken it out on the road to test the Limited Slip Differential. Is this true or were they just using an excuse to rag my car? Anybody else had an MOT where they drive the car on the road?
