I hear that the 2valve mustang engine is not good. is that true, and i also hear that you can make your 2valve a 3 or 4 valve engine, where can you get those parts, and how much? and how much of a difference will their be in performance? Also, if u take a 2valve and swap it out for a 4 valve, does that make it equivalent to mach 1 or a cobra engine, minus all of the extra performance parts that it already has?

By the time you swap out heads for 4V cobra heads then install 4 new cam shafts, valve covers, a whole new cam chain system, solve fitment, and retune the car/ reprogram the ECU it's cheaper to just buy a used cobra engine - and im leaving out a lot of steps. Plus it wont even be as useful as a cobra block, they are alluminum for weight and have a forged bottom end, and a helluva better intake system (which actually would be needed cuz urs would no longer bolt up to the 4V heads).

Excluding the 99 and 01 Cobras, which only have a forged crank but not rods/pistons.

03 and up are all forged.

And the mark VIII engine.

a little 2V with a big s/c can go past 800 HP to the wheels..... is that still no good?

my 2V has over 400 to the rear wheels right now.

thomas91169 · May 17, 2007

you can make good power with sticking with 2v. a good head/cam combo will go a long way, and be alot cheaper than a 4v swap, and probably perform better versus a stock 4v swap.

merc123 · May 17, 2007

Get a 2v long block...

ADRENLN · May 17, 2007

yea, i stuck it out with the 2v and im hoping for around 500rwhp this summer.

That is patently false.

01Steeda · May 17, 2007

it has alot of potential. in stock Short block form your going to be limited to about 400rwhp.. some push more and last but most dont.

If you can find a donor car for the 4V swap for cheap then it is worth it, otherwise put forged internals in the 2V and boost the crap out of it.

SaleenGT2001 · May 17, 2007

forget the 4V and buy a good s/c. you will not regret it!

04GTMustang · May 18, 2007

the 2v has plenty of potential the only thing that sucks about the 2v over the 3 or 4v is that it doesnt make as good of power with just boltons. But slap on a supercharger and it can put down some good numbers.

but than again..

"i have now offically spent more money on mods than i paid for my car! when will it end??"

.. no sweat, just thought it was funny. 2v FTW!

+1

Im at 479RWHP on the stock bottomend...yep a 2V . STOCK 2Vs arent fast...but with boost they REALLY come alive. BEST bet is to do like SaleenGT2001 suggested and through some form of forced induction at the 2V. Its not worth the hassle of going 4V unless your wanting to make over 800-900RWHP....because the 2V can get you there.

There are many different options when choosing a motor for your mustang. As with everything in life it has to do with what kind of cash flow you have and what kind of power you are looking to make. 2V cars are very reliable and can safely handle just under 500HP. The block usually is not the weakest link, it is the guts inside the block. On my car it was the main bearings. 2V parts are also less expensive than the parts for a 3V or a 4V making it a good choice for a racer on a budget. I would say build what you have, and save some time and head aches. Unless of course you have some one there who knows what they are doing and can help you along.

false. you'll barely get over 300 rwhp with heads/cams on a 2V. Buy a cobra or 3v stang and dont look back. The 2V sucks unless you want to spend a lot of money. By starting with a 4V, you'll have a much better platform to start with if you plan on doing some real mods. If you want a quick daily driver, get a 2V and just slap a KB, tune, exhaust and gears on it and call it a day. Dont waste any time/money on bolt ons. but then again, you can find a used 03 cobra for the price of what you'll pay with the right setup and supporting mods to have a safe 400+ rwhp 2V.

These motors are strong as hell. They can handle 400-450whp. Stock, they'll go 300,000 + miles (Taxi's and cop cars have the same engine). They'll respond decently to bolt ons, and blowers/turbos are even better. There are a lot of 1000+ HP stangs believe it or not.
