Default Hello everybody [pics]

i've been lurking CL for the past few years, gathering much information about the SC, waiting for my time to get my own. I finally picked up a nice 93 5spd blk/tan the other day from a CL member, and as soon as i get the requisite paperwork, im going to tear up the streets! (legally of course )



Planned mods:

- 20% tint
- Rain Defletors
- 2.5" exhaust with magnaflow mufflers
- BFI

As a token of my appreciation to all that have given helpful information i have the complete 93 (wiring should be the same for all years) wiring diagram.

Welcome!

You should also clean up those headlights, it'll drastically change the look of the car...

Thanks for the link! =)

You're right, the headlights are a bit foggy, especially the pass. side. The driver side one is pretty much clear.

No problem. Helping those who helped me.

Your SC was one of the reasons i wanted one in the first place

Any kind of good rubbing compound, a rag, and about five minutes....and your headlights will look like new.

Nice car, btw. Excellent choice. Slam it on some nice wheels, and youll be straight pimpin. Ha,....like me. lol

car looks great.

beware the 2.5" exhaust on the 3L. Unless you are talking about a single exhaust, that is WAY too big and your performance down low will suffer hugely. Your car will get super loud and ultra slow until about 4k rpms when the pipe size would be only modestly justified by the flow of the exhaust gases.

2" mandrel bent or 2.25" crush bent is the correct exhaust sizing for a stock 3L. If you want to boost, all bets are off. Anything larger than this will present too much room for the exhaust gases to get lost on their way out of the engine. This is bad news for performance.

Hey Blizzy I have an (sc300)with a greddy mx exhaust it's 2.25 in piping ....would I gain anything by replacing the center cat/pipe with a 3 inch mid pipe or would it be over kill. I'm also concerned about it being to loud ?

Sorry for the thread jack... Nice SC you got there

2" to 2.25". Like Mark said, too big and the exhaust gasses get "lost" on their way out. 2" would be my preference on the 300, 2.25" on the 400.


Also, WELCOME fellow Jerseyite!
