we need to add some vr6 bolt ons
 
#5 ·
Like what? Nothing really cheap for the 24v engine, they did such a good job engineering it there's not much to upgrade besides ecu and cams and exhaust. Now if your budget for bolt-ons is a couple-few grand then you get down to business without going turbo. 12v a little different... might be a few more options.

Hey, how about a Potential Buyer/New Owner "things to look for" list? I started one in a post a couple of days ago...feel free to dig it up and use it if you like. Or I can if you like -- would I just copy and paste into a new thread? Mike

I meant something more model-specific (MK4, in my case). Like this:

Brake light switch: the correct one is green.

Hazards: if you have any problems with your hazards or turn indicators (the turn indicator relay lives inside the hazard switch), then it hasn't been done.

LATCH system: look for some stickers on the bottom of the rear seat uprights.

Other things to look for (not recalled, but upgraded):

Coolant temp sensor: new model is green (old is black);

Backup light switch (if your reverse lights don't come on and you have a manual tranny): figure out if you have the black, bolt-on-from-the-top version or
the screw in version and replace accordingly;

Clutch switches (manual tranny only, of course): there are two next to each other - if you can start your car without pressing in the clutch pedal (or you're having cruise control issues), replace them both;

Door lock module: if the courtesy light on your driver's door doesn't light up when the door is open (and the bulb is good), you may have to replace the door lock module -- there's a non-replaceable (not easily, anyway) micro-switch in the module that "tells" the car's ECM when the door is open and, when not working, all sorts of little gremlins pop up (do a search if you need to replace the module, there's been lots written about it);

Trunk lid microswitch: if the courtesy light on your trunk lid doesn't light up when it is open (and the bulb is good), you may have to replace the micro-switch on the lock mechanism;

Fan Control Module: A/C stopped working suddenly? Compressor not engaging? Most likely your FCM needs replacing: $50 online (or $200 from a dealer) and about an hour of your time.

High-mount cupholders: if yours aren't broken, don't worry -- they will be soon enough.
