2v-4v
 

if have a 99 gt can i get a 4v engine? such as the mach 1 or something

would it be worth it?

On an older car, say a 99, yes it would be worth it, givin the miles and trade in value. My shop just did a mach crate motor into a 2000 GT. Cost was just over $10K, for motor, intake, and full exhaust. Made 330rwhp with that and a basic tune!

I probably should know this, but what is the difference between the Mach 1 crate motor and the engine I have in my mach?? Just curious cause 330rwhp is a lot of RWHP with just a tune so obviously something has to be different from the regular Mach engines.

It's the exact same, but Mug said they also had a full exhaust, on a 4v engine thats an easy 40RWHP more

duh, I should really take classes on how to read better! ha ha ha

i was reading the 4.6 5.4 swap and would it be better just to go ahead and do that?

money wise which is better?

horsepower wise which is better?

and would doing an either of these take a lot of mods to make it work?

a subject near and dear to my heart. I suggest 4V swaps only to V6 cars because you'll have to swap out most of the wiring harnesses in the car and that's a serious beyotch.

A 5.4 is potentially much easier...like almost bolt in easy. You'll have to get a set of intake adapter plates from Reichard Racing if they still have any, and an 8 bolt flywheel and clutch, but other than that it's a pretty straight forward event. Minor exhaust mods are the worst of it.

You need to define what kind of money you have to spend and how fast you really want to go. I'm going 5.4 2V and it's pretty simple but I'm also building my motor with a forged bottom end and a little intake, head and cam work so I'll be looking for a good bit more power than a straight swap would yeild. Still a 5.4 is a killer alternative and there are companies out there right now putting the finishing touches on their own mustang 5.4 intake solutions (at much urging of myself and others).

I got my 5.4's for 80 and 550 bucks complete. They are common under a grand and there's really minimal work to install over and above your normal engine replacement.

If a 5.4 is in your future or you want to learn more, check out my thread in this forum. Anyone interested in a 5.4 swap.... yada yada yada is the title... It's constantly active lately so hop in and take a read.

um.... hell no
 

No not worth it in the least... for 10k you can gave your stock GT forged out and badass supercharger or possible even a twin turbo - a single for sure - that would put you car at 600-1000 hp easy... so there is no point in doing a block swap. esecially to a mach 1 - ;( - damn u can buy a cammer or a freakin roush 500hp n/a for that geez. :bash:
