To the uninitiated, changing an S14 headlight bulb may seem a simple job. How wrong they would be!
Access to the back of the headlight units is so restrictive (especially on the battery side) that you would find yourself fiddling about for up to an hour blindly trying to get your fingers into very difficult spaces. Note that access to the S14a headlights is much better.
I have read via a US forum that many people think this guide is pointless and that the bulbs can be changed easily without removing anything. The bulkhead clearance may be more generous for models fitted with the US KA24 engine as opposed to the SR20, so if you can do this, great. For those with SR20s without Japanese or Donald Trump hands, this guide is a piece of piss and much faster. Until you do it, you won't actually understand. It is also interesting to reflect that this process was shown to me by someone at a Nissan dealership. Where time is money, you need to ask why they do this if it's unecessary and much faster with them in place...?
Ever thought how loud the road noise is coming from the back of your S14? There is a very good reason for this: when Nissan were thinking of ways to save money on this car, they discovered two massive gaps they could avoid soundproofing. By dealing with these, the amount of road noise is quite dramatically reduced.
A lot of people like to make their S14 a bit more anonymous by de-badging it. This is fine, however, when the Nissan badge is removed from the bonnet, you are left with two locator pin holes to fill somehow. This is why I preferred the replace the badge with an alternative.
In the UK, many owners of Japanese cars are afflicted by huge front bumper 'bricks' for mounting standard length number plates on. If the car was designed without a 'brick', its never going to look good with one! This can be easily rectified by 'de-bricking' or removing the plate mount.
