What Phil said. You can just straight up buy a FRPP car. The new SC packages make me exited for the future of the GT500. The modified GT is so capable Ford has got to do something spectacular to the 500, or just can it outright.

Honestly, the GT500 is already almost at the limit where throwing more more horsepower at it isn't going to do it anymore, for me anyways. 440 in the BOSS is crazy enough as is. You're hitting the limit of what you can do on the street stoplight to stoplight. An independent rear with 500+ horsepower minus the blower and you've got me really really interested. I'd like to see a successor to the Cobra-R more than just another really heavy blown Mustang. Ford knows it's audience better than me though...

The rumors of an EcoBoost v8 with twin turbos and direct injection are still swirling. I've heard numbers like 650hp thrown around.

With the DOHC 32-valve heads, don't you have to worry about hood clearance issues? I'm especially wondering about the original Fox-4/SN95 (96-98).

You will not have to worry about hood clearance issues, the SN95 Cobra came with the 32v 4.6 and the Cobra intake manifold, so it should clear everything fine.

Not so much hood clearance issues as strut tower clearance issues. The SN95s won't have a problem as they eventually received the mod motor in both 2v and 4v flavors. The Foxes seem to accept the DOHC engines fine as well, provided you have the correct motor mounts. Several aftermarket companies make motor mounts and k-members to make the DOHC swap a bolt in affair.

Mustangs dont race in ALMS (and never have) or Grand am (which is what im assuming you mean by RSCC) They race them in Continental tire challenge and World Challenge these days. but you're right in that ford will sell the FR series mustangs to just about anyone with the money. This guy showed up at my last track day at monticello and was rollin around in the green (novice) group

Assume the Mustang is either a new edge or a pre-2010 5th gen. Ultimately it is cheaper to buy a 4v engine out of a junkyard or whatever than it is to convert a 2v or 3v. It's not so much the heads as it is all of the little parts that make it so expensive to do. Everything bolts up (unless you have an early 4.6L DOHC block with knock sensors, but they just need to be ground down), but you'll end up paying more than you would for a used 4v. Hellion makes good poo poo. John Urist is the owner and he knows a thing or two about turbos. He also happens to be the NMRA Super Street Outlaw champion for the last 4 years in a row (albeit with a Procharger supercharger). HPP Racing is another good turbo kit manufacturer if you're interested in going with snails.

Oh yes, very much into snails! I think I like the Hellion single-turbo kit. Anyway, last question about the head swaps and I'll bury it after this: what about 5.4L heads - same deal as the 4.6L heads?

If you're talking a SN-95 GT swapped to a Cobra motor then the only part that may not work is the upper intake manifold. The Cobra manifold was huge and I'm not entirely sure the bulge in a 96 Cobra hood was fully cosmetic. There may be rubbing issues but I'm not sure. You can image search an SN-95 Cobra and see that little bump. GT manifolds were tiny little squares that looked like a dust buster would be more effective up there.

VibrioCholera posted:The Cobra manifold was huge and I'm not entirely sure the bulge in a 96 Cobra hood was fully cosmetic. There may be rubbing issues but I'm not sure. I'm not 100% either for the SN95s, but a cowl hood for one of them will run you a couple hundred tops if you look at Mustang classifieds on corral.net. At any rate, the only real answer is to drop a '99-'04 Lightning engine into your Fox, cut a hole in the hood, and re-create the Muscle Mustangs and Fast Fords project Frightning.  10 second ETs with the stock Lightning engine in a four eye chassis.

Anyway, it's the whole "buy a car which she can [learn to] drive, but that I can also enjoy when I drive it" problem. She's expressed anxiety about driving my Skyline due to the whole right-hand drive thing, and I want to give her the chance I never had by teaching her how to drive in a manual, rear-wheel drive vehicle. The Mustang GT is just the current front-runner; I've changed my mind a few times throughout the course of the summer.

Taaaaaaarb! posted:I assume you're talking about the Mustang, but which one? The dead man clutch was the 944 I learned in. I had been driving for 13 years by the time I learned stick (only legally for 4, hooray for rural areas), but 300 hp for learning to drive stick was intimidating even to me, doubly so because it wasn't my car. Even knowing the mechanics of how a transmission works and knowing that I was doing nothing that could possibly gently caress it up, I was nervous as hell. Shifting into second was nearly as hard as getting the car rolling in the first place. I would seriously suggest buying something more forgiving in the transmission department on the cheap, cheap enough that you don't need a loan anyway. Then trade it in for the Mustang/other fun car a few months later once she's comfortable with it. Choosing the right car will prevent you from biting it on the depreciation and you've got that trade-in value to deduct on top of any extra you save up on a down-payment. My second time with a stick was for that same friend's newly acquired (by marriage) 1995 MX3. 88 horsepower and even less weight than the 944 with a heavier flywheel and I was an expert within the hour.

I have a recipe for you. Stock dimension shortblock with forged internals. MHS ported 2v heads MHS turbo cams Stock intake manifold BBK 76mm plenum/throttle body Single turbo kit with a Master Power T70 turbo with a .81 A/R housing Fuel system Magnaflow cat-back exhaust Depending on the turbo kit, fuel system, and if you supply the labor or not, you can be in this for as little as $5k or as much as $12k.

Hypnolobster posted:That sounds fantastic. Stop complaining It would be fantastic if the guy who did it for him had done more than a half-assed job and the car hadn't already been beat on by previous owners, which included a 17 year old girl (Which I admit would have been hot when she had it). For instance, until I drove his MX-3 I thought clutches were supposed[i] to have two levels of tension in them instead of a smooth action. Pressing the clutch down for the first ~2 inches provided about the same resistance as your average throttle pedal, and then suddenly ramped up to trying to press down on a brick wall. But the friction point was 1-1.5 inches [i]after that point. Being new, I thought the sudden extra pressure meant the clutch plate had been pulled out of contact with the flywheel, so now I was the only thing pushing back on the springs. Because of this, even when told where the friction point was, my body just refused to believe that it was anywhere other than that spot. You can imagine what kind of havoc that played when you're trying to learn to shift smoothly. That just covers the clutch itself. I could probably make a megapost about the problems this car has. Most just weren't noticeable until the LS1 got put in, thanks to the shifting weight and the doubled power.

In near record time, skip shift in the 2011 Mustang can now be turned off via hand held tuner. No need to fool around with jumpers like our neanderthal LSx neighbors.

Haha, in my goat I like to play a little game where I try to keep the skip shift light on for as long as possible (it only comes on at a very specific window of RPM and speed). Current record is almost 30 seconds.  And for the record it can be disabled by a tuner too (although I dunno if any handheld tuners can do it).
