4.6 performance help
if you have been around the block so much why did you put on irs on your mustang makes no sense at all. or the irs swap mean you went to a straight axle but if you actually put irs on a mustang you arent very smart
Labor must be cheap where you live. Around here 1 hour of labor is $100+. Plus there is no way you can even get parts for $400. Maybe if you get them off ebay or something I don't know. Lets say it is $400 in parts then add around 3 hours labor for the rear, another $400 for the front diff and 5 hours labor for that cause it's a pita. That's $1600 so 2k is a little high 1800 is possible and 1600 is about the cheapest you'll get. Now I'm gonna specify I'm including axle bearings and seals and carrier bearings and all because you'd be a fool to go deep enough to do gears and not do those.
To the other guy about the motors, I know you're right the engine blocks and heads are the same, I figured you were comparing the whole setup in the mustang to the setup in the trucks. The intake makes all the difference in the two different vehicles, the hp/torque ratings of a mustang gt and f150 are not the same.
Theres more than 1 kind of racing in the world... I would hope somone who knows so much about mustangs would know why someone would want to swap to an irs. :P
I was originally going to put on a torque arm and watts link but it was still my DD at the time, so i didnt want to consequences of them. An IRS handles just as good as a basic TA/WL setup without the ridiculously rigid ride. It was a no brainer to swap in an IRS(and it was free)
And to the guy ranting about someone speaking from experience... there are thousands of others on boards that will tell you the same thing i did... and there are timeslips to back it up lol.

O now see why you put a irs in your car to help but it still makes no sense if i was going to make a auto cross car it would be a fast light car not a bulky mustang that will still lumbar around its to heavy in my opinion i would rather see a rx-7 that is stripped and revs to the moon do a autocross track all that mustangs are they are not known for handling each to their own i guess
Once you address the crappy 4 link suspension design a mustang handles as well as anything else.. Not to mention the IRS gets a GT closer to a 50/50 split ratio of weight distribution. I would love for you to take a ride in an american iron car...and tell them that they should be using an rx7 or something else... lol

man im a huge mustang fan one day i plan on having one. but right now i needed a truck... autocross just isnt a mustangs forte. i hate foreign cars but i can respect the fact that they handle ten times better than a american... and if your gonna sit their and try and say a mustang with a irs will handle just as well as a subaru not happening and then the subaru will go wax the mustang in the quarter ... once again im going to state im a huge mustang fan
Right now you sound like a complete armchair qb... until your doing it, your internet opinions are just that... opinions. The people with AWD cars usually are some of the worst out there because they depend on the AWD to make up for their lack of skill... and they usually come in a few seconds back. The cars that are the competitors are your RWD miatas/s2000s/cobras/vettes. And YES, the IRS handles just as well as a torque arm/PHB setup on a live axle... so yea it handles pretty darn good.
Again, your comments are that of someone who has not, and probably will not ever do it, so you might want to just sit this one out and stop making generalized comments about something your not familiar with. Their are tons and tons of guys on the net that autox their mustang and have great results doing it.
lack of skill come on now im just trying emphasize that awd will handle better and they do people running s2k and miatas those are both foreign. and they probably do very well tbut the fact is a mustang was meant to go fast in a straight line not on a track you throw any type of power at the mustang your just gonna spin you throw a bigger turbo injectors and all that other stuff at the subaru it will handle it in the corners mustang wont so then you arent running your car to the full potential and your irs was free probably because a dude with a cobra was like **** this **** give me a 8:8
"the 4.6 in a cab or mustang is not the same motor"
Actually it is exactly the same motor. The different motor is the 4.2 - 6 which was stroked for more torque. All the F150 engines from the years of these threads can get the job done for a truck, so I never understand what the problem is with the "poor performance" questions. I guess it depends on whether you want a truck or a street racer.

And the IRS is an 8.8, again, i would assume you should know this based on the fact your dishing out so much hardcore knowledge on a sport for which you dont compete nor understand apparently.
The IRS was free because the guy with the cobra was pushing 600+ to the wheels and didnt want to snap his halfshafts when he launched on full slicks. My car launches better with the IRS than it ever did with the SRA. They are just more expensive to make stronger, so people would rather swap to an SRA. And to say AWD is better for track driving is foolish. An STI/Evo was designed for off road/onroad racing... not circuit driving. Look at what the real teams use....RWD cars are the way to go. The guys that race them in autox just use the AWD as a crutch... and more times than not end up killing cones because they cant overcome the understeer that those cars put out while on nice grippy tarmac.
