im having a problem sorcing a part its the external b piller trim (the gloss black part on the top of the door) ive seen some sites calling it the sail and a few calling it the b piller but no one seems to sell them are they even replacable? The only ones ive found are some stick on chrome ones but i want to keep the car looking stock. Mine are a bit scuffed like someones been using it to open the door with a ring on or something so are probly reparable if need be, any ideas?

right this is my maths. (rim width/half) to find the wheels centre. then plus or minus the offset to find out where the rear face of the wheel would sit. by that centre line so. (rim width/half)+? then measure the resulting number from the hub face out to the arch and see where it lies..... is that correct? ie a 245 rim with an offset of -33 would sit 89.9 mm away from the hub face. :detective: i think im right its just i cant spell very well and the maths isnt exactly top notch neither.

Hi, is there a good 300 mechanic in the South of the UK. I live near Gatwick.

Got the engine and box out in one today, only pain was, although i drained the gearbox oil, more gushed out the back as we lifted it at an angle, managed to catch most of it, but had to jetwash the drive off ready for tomorrow. Cleaned the engine bay of grease and grime, ready to paint then hopefully new engine and box in on thurs :thumbup1: Had no major problems apart from a subframe bolt spinning, but got that welded to get it off and a new one to go back in, so far so good. Took a couple of pics with the engine in the air, would have taken more, but got covered in oil. Will take some pics of the new one going in as its nice and clean :biggrin:

how much power auto box can handle ?

just fitted a replacement autobox today, refilled with oil to correct level but i can select gear 1 or 2. its as if something is stopping the selector from going into gear. it moves from park to drive fine, was to dark to see underneath at this point. also when in drive it stalls when i apply the brake. any ideas?

can anybody tell me the length of the tie rod and what size the threads are at both ends on a 1990 300zx many thanks john

hi all there`s no heating in the car ... motor blows air but it`s not hot ... any ideas why ? heating matrix bypass mod ? :)

I bought a sump plug a while ago from Z1 and fitted it yesterday whilst doing and engine flush. When I dropped the second lot of oil I saw some debris on the magnet. I thought - that's cool it's obviously doing it's job. But NO! The magnet on the end of the sump plug had fowled a baffle plate inside (I assume) and half of it had disintegrated and the debris was the broken bits of the magnet its self. I'm not sure if i have all of the magnet pieces but I hope so. If not, then that means there are bits of magnet debris somewhere in my block! When I compared the length of the two sump plugs, the magnet was about 4mm longer than standard - just enough to cause …

what is the rpm ment to be on tick over? as i think mines a bit low about 500rpm's.

anyone got a set of the z33 rays alloys fitted, the fronts are 225 with an offset of +30 so should sit lovely. the rears are however are 245 with an offset of +33 how would that sit? only other thing im wondering is that at 18" with a profile of 45 will they not be slightly larger than the standard oem diameter? and cause speedo issues etc?

How is an Engine Oil Made? There are two main components that all engine oils are made of, basestocks and the additive package. The base fluid typically makes up the bulk of the oil (70-95%). Additive chemicals are then added to enhance the positive qualities of the basestocks and to overcome whatever negative qualities there may be. There are two main types of basestocks, petroleum and synthetic. Petroleum basestocks are a purified form of crude oil and have been used as the base for automotive lubricants since motor oils were first developed. Synthetic basestocks, on the other hand, are chemically engineered in a lab specifically for the purpose of l…

Well what to do? Had my zed for over 2 years now and is still in bits. I just dont seam to have the time to put it all back together! I Have all the parts I need and extras plus some nice bits I have got from you lot hard Pipes, new decats, elec boots etc. Its now got to the point of just leave it in my garage as I might have time one day, sale it in bits or as one lump? Would be a shame to scrap it as the shell is in good nick. does anyone fancy a new project????

Hi, well car running well now except for missfiring on the over run, when I take my foot off the gas I get the banging out the pipes....Not all the time though. I am running 555 injectors at 16.5 psi if that means anything to you boffins out there ....lol.

Hi guys i have been reading though some of the old post regarding head gaskets and i see that you both say that its better to replace the engine or do a major strip down rather than do the gaskets if its been over heating. Now im looking to take my engine out for other work and i was thinking of doing the headgaskets while its out. I have no over heating problems at the moment and have not had any since i have had the car and as far as i know its not been done before. My question is am i better to leave alone or will it be ok to do with out having to strip the engine down any further than the head gaskets? Thanks dave

Need a bit of help here, When the car is not running i can slide throught he gears very easily. When the car is running it is quite stiff to get the gears home. I am running a Z1 shortshifter but am wondering why it is harder to change gears when the car is running? Is there something mechanical i should be checking as well as the fitting of the short shifter? Cheers

had my car back of zedword and alls been brill for days went out yesterday for a bit of a drive and it started to miss fire on cylinder 2 anyways investigating tonight and with the car cold it seemed ok and when it gets warm it started again 1500>2200 rpm but would go when pushed. does it on idle/costing no load speed checked all my cables and joins and plugs and all is good ... then i disconeced the O2 sensor on that side .. and bang no missfire and drives nice and smooth would a faulty/bad O2 sensor make a missfire PS i did read a few posts about the O2 sensor and testing it at 2000rpm as this is where it works thanks again …
