I wish I could help you. However, I don't speak your language.

I would advise that you do a search.

Gearbanger is a ford tech and a cougar enthusiast he will help you out...

My guess is that making that car into an 11 second car is going to be very problematic and expensive.

You say you beat a GTP, that is about as impressive as smoking an 18 wheeler...

a 95 Cougar's 4.6L isn't even an NPI motor, it's pre-NPI motor so I'm not sure much will swap with 96-2004 Mustangs without upgrading the heads & intake to a later year - maybe pulleys but that's not going to make much difference. Yeah, 99-04 PI heads & intake are your best bet since you have to swap them anyway - just about any 2V 4.6L performance parts are geared towards the PI motor and mostly for PI motors in a Mustang.

I think there are two problems with the Mustang headers in your Cougar - one is that the pre-NPI heads have different exhaust ports than NPI/PI heads and the other is that the Mustang headers won't clear the Cougar chassis.

A head swap is still going to leave you a long way from 11's though - those Cougars & T-birds are heavy compared to an already not very svelte Mustang - so you've still got a lot of work to do after that.

The best place to find Cougar & T-bird info TCCoA - I highly recommend spending a lot of time reading through their tech articles and browsing the forums - they really know their stuff over there.

I am also a Cougar/Thunderbird fan and I am familiar with these cars. I do see a couple of "problems" with the plans.

While the 4.6 modular motor in the Cougar is very similar to the Mustang, but there are differences. The exhaust is actually closer to a truck style exhaust in that the headers are in a Y configuration which flow into a single pipe through the drive tunnel. Then into another Y pipe dual muffler configuration.

Bottom line, a Mustang exhaust will not work.

To me, one important difference between the cars for the home shade tree mechanic is the 4.6 Cougar/Thunderbird motor can not be removed from above with a crane. The car's craddle design means that the body is "lifted" off of the K-member/motor/transmission. This places a motor swap in the shop league as special lift equipment is needed.

A PI head swap can not be done "in car" because the oil pan can not be dropped "in car". So, while something like a PI head swap could be done, the motor removal makes the job harder than first glance.

The suspension is totally different between Cougar/Mustang. Nothing will interchange.

Even the wheels/rims will not interchange. The bolt pattern is 1/4" smaller on the Cougar.

I sure that you have noted how much softer the transmission has been set up on the Cougar. This can changed with a shift kit and tune.

A Mustang's underdrive pulleys should fit the Cougar.

I had a 97 Cougar that I really liked. It was originally purchased to be a "sleeper". After owning it for a while, I discovered that the job was going to require much more than what I could do in my driveway.

Beside, the car drove GREAT, got good gas mileage (20 city), and was a very smooth ride. So in the end, I decided to just drive it.

Good luck.

PS, recommend to not posting threads about street racing. Trouble!

Whatever man, sometimes you gotta do what you gotta do the OP's post WAS garbage... Quit whining in tech.

Don't confuse whining w/ somebody that feels for someone whom obviously has a disadvantage and wants help, you can defend your "buddy" all you want but this is a place for everyone which whom wants help, sounds like your kinda of biased for some reason, info is for everyone who wants to better themselves. Quit being sheeple! Quit whining about me whining in tech:Zip2:.

Hey Winters98GT/trombonedemon/Kilgore Trout,

Since I do not have a long history with this "forum" thing, I do not know about the "history" here. I wonder, is it worth asking about?

Or will I regeat leaving the "tech" world for the "talk" world?
