So I'm trying to take out the factory Mach 460 head unit in my 2000 GT. I got the tool and removed the cd player no problem. When trying to take out the head unit, I pushed the tool too far into the holes on the left side and i heard a little crack noise. Now I can't feel the spring with the...

Stupid me... I got carried away while tightening the plastic nut that you loosen to drain the coolant from the radiator. The stem of the bolt is still in there and it's obviously tight enough, so there's no leaks. I'm not in a rush to get it fixed, but I want to get the stuff so I can do it...

So as I mentioned in another thread, I don't like the stinkyness of my o/r prochamber. I'm running about 11.5:1 afr, so maybe that's why it smells a little more than normal, I don't know. Anyways, I was looking at cats on summit and jegs. Is there any one brand that is the best? I know...

I have an o/r prochamber with mac longtubes and I'd really like to toss the o/r and buy a catted h-pipe. I've searched the world over for a catted l/t prochamber, but couldn't find one. Does anyone know where to get one or any other catted l/t H? Thanks

I just finished installing my mac l/t's and o/r prochamber, to compliment my existing mac catback. I started it up last night. I know I'm supposed to have it retuned with the addition of these parts, but I took it for a very easy 1 mile drive just to hear it. I was very disappointed, I had a...

So I'm finishing up my week-long Mac longtube install and everything's done now... Except the prochamber won't fit! It seems they made the header end of the prochamber too wide, should I try and bend the pipes closer to eachother? Does anyone have any other advice for me? By the way, I...

I'm installing my longtube headers and am going off of this write-up: http://www.fnsweet.com/garage/lt_install/index.shtml On step 15 when it says "Remove the nut attaching the motor mount to the K-member using an 18mm socket..." Is that a mistake in size? Mine is bigger than 18mm, looks...

I have a 99 GT with a vortech blower, and all I have exhaust wise is a mac cat back. I want to buy some mac longtubes with a matching o/r prochamber. I want to louden it up and gain some power. Here's my dilemma: Where I live (Connecticut) we have to get emission tested every 2 years, they plug...

I have that parchment interior and it's a 1999. When I bought the car there was this black... gunk all over the little crevices of the plastic panels. It looked dirty and nasty but I couldn't clean it with anything I tried, 409, fantastic, armor all, nothing. Until finally... I mixed some Jax...

So I think I've overdue for a wideband a/f gauge in my car. I want to get this gauge: http://www.autometer.com/cat_gaugedetail.aspx?ref=search&gid=3604 because it matches my boost gauge and I have an open spot in my pillar. My question is this: I can get an LC-1 without the gauge for $199...

Okay I'm kind of taking this opportunity to think aloud. I've been thinking about what I'm going to do with my car. I'm turning 19 in a month, and one day I want to have my car be fast enough to run low 10's and not need to worry about ANYthing on the street, including those darn turbo Supras...

Can anyone tell me the resistance I should have on my mustang? I have the vortech mongoose kit, I don't know if that changes anything or not. I couldn't find any instructions about how to do this, if anyone knows a write up, please post it. I want to make sure my COP's are good because my...

Hi, I have a 1999 GT with the mongoose Vortech kit. Since then I added just a mph powerpipe and changed my setting on the x-cal from 6% lean a/f (worked best on dyno run) to 2% rich. It was running fine for about 4 months. Then it started to bog down really bad (maybe lug is the word?) not...

I spent the last hour searching through old threads about which differential fluid to use. I couldn't find a straight answer to my questions. I have a 1999 GT, and it has 75k miles. To the best of my knowledge, the fluid has never been changed, definitely not since 62k miles when i bought it...

Hi, I have a 99 GT with a mongoose vortech sq kit and the mph powerpipe. Lately, the car has been missing under load. If i were to put it in say 4th gear at 2500rpm and stomp on it, there would be a constant bububububububu almost like making your lips vibrate back and forth, that's the best way...

Sooo i have a 99GT and it's got (engine-wise): Vortech SQ supercharger Accufab TB and C&L Plenum Intake spacer Modular Powerhouse 4" "Boost enhancing pipe" I'm waiting to get it dynoed after the boost pipe, which will with a bit of luck land me at around 370rwhp. I don't want to get...

So I have a 99 GT with a Vortech sq, it was about 360/350 before the boost pipe. I encountered a late model firebird, probably around 99. He said he had an LS1 and that it was all stock, sooo we raced. there was some traffic so we could only go once. we went from 60-130 i started off in 3rd. he...

Has anyone removed the two far-back cats on their stock H-pipe? My co-worker (who has tons of experience with stangs) suggested the idea to me. The only problems I have with it are, will I need to get the MIL eliminators? and would I still pass emissions? I would chop out the cats and replace...

my car is "black" but in in the sun it looks very very bluish, milkyish, and not black. Is there anything i can do or buy to help me restore the car's original blackness, without repainting the car?

Hey guys, I was checking my spark plugs and cops since my car has been studdering, anyways, I realized this thing was unplugged, but I have no idea where it's supposed to go. Can someone PLEASE run out to their car and check for me, or if you just know, that's cool too. This could be the source...
