4.0

What's up y'all I am planning out a single turbo kit for my 09 4.0L. Before anyone says it, I'm doing this just for fun and because I finally have some adult money and a garage. I've had this car since high school, and always wanted to V8 swap it. However, I came into a steal of a 96 GT. Now...

I have a 2006 mustang v6 and I'm wondering if anyone has tried one of these dampers out? Also where should I mount it ok my car exactly? Universal 6" Engine Torque Damper Kit Blue Brand New | eBay

Hi everyone, I have noticed that my passenger side headlight on my 2005 V6 is always misted up and the drivers side headlight is fine and never seems to mist up. I thought that maybe the drivers side stays clear because the intake system is that side and I thought that maybe more air flows...

Hi everyone, I need some advice urgently please. I have a 2005 V6 Mustang in the UK and I recently purchased an S&B intake system, a Boom Tube axel back exhaust and some stainless steel shorty headers that I got off eBay for about $100. I think a guy makes them from scratch or something. Very...

Over at MustangForums.com they are trying to put together a group buy for a metal thermostat housing to fix the problem with the plastic ones breaking. They need 30+ to get a group buy price of $135 each (versus the single unit price of $179). Group Buy Alluminum Thermostat Housing! All...

So I've owned my Mustang for a couple of moths now and I've dumped a decent amount of money on making the exterior look Great, also my Ford Racing Dual Exhaust arrives tomorrow (Hopefully). I love this car, but I feel the need to have a V8. So here's my question, I've heard that its smart to buy...

I recently bought a 2005 4.0 v6 vortech h.o v2 supercharged mustang, 3.5" exhaust piping all the way from the headers.. But recently i was drinving my car and the gas was almost out and then all of a sudden my mustang starts to kind kick and feel really rough when coming to a stop or slowing...

My 06 v6 4.0 has an automatic in it, and I wanted to swap out the transmission, I bought what I thought was a T5 but when I looked at it, turns out it was a T3650 for a 4.6 V8, will this tranny work on my 4.0? Or should I just go trade it for a T5? Thanks in advance

I'm sort of undecided as to whether or not I want to save up for SSM's 2+ Heads. It's just heads, no cams, and they run about $1600. Now with gaskets, studs, specialized tools, and the the endless misc which will go wrong, I tallied it up to about $2k. I really love the idea of making N/A...

Hi, i have a 2005 mustang with a manual transmission, trying desperately to find a turbo exhaust manifold to put this turbo on my mustang. Ive looked everywhere i could possibly think of, and havent found a single one. I pretty much have everything else, and i need this turbo under my hood...

okay, so we went out and raced again today and i had a 130lb passenger to video. Here's the link to the video. YouTube - 2009 ford mustang vs 2006 Nissan Sentra Se-r Spec V What does everyone think?

so the other day me and my friend had a little argument about whose car is faster. He has had a truck since 16 and finally got a somewhat performance car. The interweb said that the spec v runs the 1/4 in 15.2 while the mustang is pretty much right there with it. His is stock my mustang has...

Okay so I'm really considering a remote turbo setup for my 4.0L with dual exhaust. Basically, I'd be replacing my mufflers with two turbos (obviously going to be a little turbo lag but its a big enough engine that I have some torque low end). I'm trying to figure out: A. What size of turbos...

Just joined the thread and the thing said to introduce myself.:yelwacko: So my name's Jake, I'm 17 so the v6 is all I could afford, I have a 2007 4.0 Redfire Mustang. All that's done to it right now is my sub and amp, shorty antenna, dual exhaust with an H pipe and flo pros, blackout panel...

I am looking to get some underdrive pulleys for my 4.0. My question how is it possible that we underdrive the accessories and there are no downsides? Doesn't it have to make the A/C run a little weaker and generate less power with the alternator? If there really were no downsides wouldn't Ford...
