i have a 01 gt 4.6 16 v can i convert it to a 32 v

 

Yes you can

 

So just buy heads and pistons

 

Heads, intake, headers, timing cover, etc. I know there is more just don't know what exactly. Pistons aren't necessary to replace.

This is the best thing to do if you want 4v and on a budget.

Sounds expensive

 

Yes, it is.

 

Well in a sense your gettin a whole new motor. Either way its gonna be a pricey job

 

Would it better just to stroke it

 

That would probably be more since you would need mods to support that.

 

Mark 8 swap, cheap dohc engine

 

Mark 8 swap, cheap way for a dohc motor

 

I have seen many other people here in the past talk about motor swaps on the SN95 cars. Those who have done it often regret their decision. Just some friendly advice, I planned on doing a DOHC on my 97 GT and once I priced it out it was simply not worth it. There is a great deal of difficulty doing motor swaps on these modern 4.6 Mustangs. Even if you do get a healthy 300+HP motor in your GT you are most likely going to have constant drive ability issues plus your GT simply isn't built to handle that extra power.

I highly recommend that you sell your current GT and upgrade to a Cobra or Mach1. Not only will you get the DOHC you desire but you also get upgraded brakes and suspension to handle that extra power. To upgrade a GT to Cobra specs is usually less reliable and more expensive than getting the real deal. I have seen several people make this mistake and pretty much all of them have regretted their decision.

Best of luck to you whatever you decide to do.

 

If you really want a dohc 4v motor then I recommend just buying a cobra. It's not much more than a gt (unless u want an 03-04 obviously). It will be worth it because the price you'll pay for the 4v conversion will probably be more than the price difference of a cobra.

 

I'm on the other side of this. I wouldn't sell you car. For me, its more rewarding to build it the way you want. Even upgrading to a Cobra or Mach 1, you'll still want to make improvements. Would I go DOHC? Probably not. But a well built 2V and supporting suspension and brake mods can be had for right around, if not less, the same price as buying a Mach or Cobra. And if done right it will outperform them. Just my opinion though.

 

You just got your GT just enjoy what you have for now

 

I couldn't disagree more, modifying a GT to outperform a Cobra is not easy. If you compare the value of a GT to a Cobra of the same year (with the exception of 2003-04) you are looking at about a $2500-3000 difference. For that $3000 difference you are getting a lot more car. Better engine, transmission, brakes, looks, seats (01-04), suspension, IRS (99-04). Even if the original poster wants to modify a Cobra it is still a better starting point than the GT. Factory fast is always more reliable and affordable than modification.

 

I guess it really comes down to personal opinion and also to end goal. For me, the only true factory fast upgrade would be an 03-04 Cobra (and there would still be plenty of would change even in building that car). If you just want to keep it stock or even full bolt ons, then sure factory fast is better. Looks and interior are subjective in my opinion and really dont matter considering its fairly cheap and easy to upgrade those. Short of buying an 03-04 Cobra and keeping it completely factory, I would not buy a cobra for the IRS, I dont think its worth it. Factory suspensions on all Mustangs leave alot to be desire performance wise and even in ride quality.

For 2500-3000, I could build my 95 GT to outperform a 95 Cobra in all areas. Would it be by much in every area, probably not. But it would still perform better.

And to a more radical, I could build an 01 V6 to easily outperform an 01 Cobra for considerably less then buying a low miles 01 Cobra.

 

I agree with your last part, the 1994-95 Cobras are not that big of an upgrade over a GT, probably my least favorite Cobras because of how minor of an upgrade it is. The 4.6 is a totally different animal, I feel even if you want to modify in the future the 4.6 Cobra will always give you a better start point. The 1995 Cobra is the same engine as your car with GT40 heads, not much else. With the later 96-04 Cobras they have a completely different engine, with much broader power gaps. A DOHC 4.6 has way more mod potential than a SOHC 4.6. Even simple upgrades like a cai, tune have huge power gains over a GT. If you plan on supercharging down the road you will get tons more power with a DOHC!

The brake upgrade is an expensive one that you would already have with the Cobra. Sure it may not be the big Brembo kits on the new cars but they are plenty good for a light weight SN95. I agree the suspension is not perfect but is probably the best balance of what you will get for ride and handling.

For the original poster's car, a P.I. 4.6 w/ 260HP the upgrade to a DOHC is at minimum going to be 45HP with a 96-98 car and 65HP with a 99-01. I don't see you getting that kind of power along with all the other upgrades within that $3000 window by modifying the GT.

 

He could get this

http://www.summitracing.com/parts/tf...tcombocontents

$3100 and has everything you need to do the swap. The kit typically nets right around 330-350 RWHP on 99-04. I even read about somebody with a 96 GT who saw 315 RWHP. So assumng a 20% drivetrain loss thats right around a possible 120-140hp on a 99-04 and 130-150hp on a 96-98. And thats with a stock intake and a mild cam. spend 800 on the intake and you could see a possible 25-30hp. And all thats on a stock motor. So its possible.

Is it easier to just sell it and upgrade, sure. But my point is that its possible to upgrade a 2V to be right there with the 4V and at a similar platform to start bolt ons. Its all about what you truly want, but the possibility exists.

 

I agree that it's possible to be competitive with these upgrades but you have to consider labor costs. This is a pretty difficult job for the average mechanic I know I couldn't tackle such a project. Funny thing is that aftermarket heads and intake on a 96-98 4.6 will give you more power due to higher compression. So I agree that its possible but I still feel it's not cost effective if you are not mechanically inclined. Also the cobra will hold its value better too.
