240SX Stereo Installation and Upgrading

Speakers

If your 240sx is Still equipped with factory speakers, it is highly recommended that you replace them. Even on a well kept, low mileage vehicle the foam surrounds are likely rotted beyond repair simply due to age (this was even apparent on a well kept low mileage S14 Kouki). Complete speaker replacement will benefit audio quality more than any other Stereo upgrade

LSx: Intake

Filed Under (LS1) by twistedsymphony on 13-09-2009

Tagged Under : , , , , , ,

Which Intake to use:
The Factory intake piping likely wont fit in your S-chassis, Some aftermarket GTO setups might work with a little modification but it’s so easy and relatively inexpensive to just piece together your own that there’s no good reason not to.

There are three different setups that are relatively easy to go with, I’ll will discuss all three. Read the rest of this entry »

S13/S14 Clutch Pedal Comparison

Filed Under (Drivetrain, Interior) by twistedsymphony on 10-09-2009

Tagged Under : , , , , , ,

Every so often the question comes up “is there a difference between the S13 and S14 clutch pedals”. The answer is “YES” however the differences are slight. I had spare clutch pedals from both an S13 and S14 handy so I took pictures of both so you could easily see the differences.

S14 Kouki: Return Faded Taillights Back to Black

Filed Under (Exterior) by twistedsymphony on 10-09-2009

Tagged Under : , , ,

The Problem:
Ok so I wanted to buy kouki tails for my S14 since the day I brought it home. After finding what I though was a good deal on a clean set I open the box to find out they’re faded as hell… the black surrounds look Grey and almost purple in some light.

After the ’09 CIP meet and seeing nearly every set of kouki tails there looking faded to garbage it’s pretty clear that this isn’t a unique problem.

The Idea:

I’d used spay on Vinyl Die on plastics before to good success so I decided to test it out on the taillight and see how it goes. This is just generic stuff that I picked up at my local Auto parts store. It’s designed to repair or re-color interior pieces. Read the rest of this entry »

S14 How To: Build an Amp Bypass/Delete Harness

Filed Under (S14 Specific) by twistedsymphony on 07-05-2008

Tagged Under : , , ,

Those who own S14’s with the factory CD player also have to deal with the factory installed Clarion amplifiers in the trunk. The existence of these amplifiers make installing an after-market stereo somewhat of a pain. Since the amp is made by a name brand and tuned specifically for the factory speakers, it’s actually in your best interest to leave it be, even if installing an aftermarket head unit. When doing so it’s advised that you use the pre-amp outputs of your head unit and NOT the speaker outputs that normally connect to the factory harness. You’ll want to look for an “amp integration” type harness when utilizing the factory amplifier and not your head unit’s internal amplification.
