What would you do?

[scott5]

I decided I am going to keep my mustang and put some time and money into it. But not sure which way to go power wise. Its going to body shop in next couple weeks to fix some things, adding a cowl hood, 03 cobra bumpers with the cobra in the rear shaved smooth, debaged and getting a flat white paint job. So here is what I am in the air about. I am not going turbo, its going to be SC. It will be getting a MMR900 shortblock with ported 2v heads and blower cams. Here are my options. I either go the Tork tech kit with a whipple/kb/tvs, a KB 2.6 for 2v setup, or a Centri (t-trim, YSI, Novi2000). Looking for 600-700rwhp. This will be infront of a T-56. So which one would you choose and why and if centri which one? This car will be 85% street and 15% 1/8th mile strip.

Kenne Bell, definite no brainer. You're going for big power, they already make a big blower specifically for a 2v. Strap it on and pump out some boost, great for the street and 1/8th mile.

I'm not a centri fan personally, Tork Tech would be an ok option but you'll have initial cost of their kit, then buying a blower as well.

In a few years I'd like to do the exact same build with mine honestly lol

 

[jymboslice]

Ysi or a novi 2k, hands down. I wish I went with a YSI instead of my novi 2000 actually. Kenne bell, no way. To expensive, for what they are and heatsoak would suck.

 

[triple-s]

Coming from my experience I went from a 2.6 to f1A cause the heat soak from the twin screw was ridiculous plus I made more power with the centri on same amount boost.

 

[Stang Lover]

Snail. Just something about hearing the idle of a centri & getting the crazy looks.

did you really just compare a 2.6 to a f1a? :dw:

no kidding the f1 made more power

 

[slow2v]

oh and OP why not use stock 4v heads and cams instead of "wasting" your money on the 2v shit? its extremely easy to make the power your looking for with sn95 cams and termie/mach 1 heads

He'll need: 4v heads, cams, valve springs, valves, retainers, the cam gears/chains, intake, throttle body, throttle body cable/bracket/cruise cable, front cover, new headers, coils, the wiring harness. Aren't the alternators different too? and the coolant crossover tube.

Those are just off the top of my heads. All of that stuff adds up and can get pretty expensive..

I'd just go with a high compression 2v motor, with ported PI heads (or trick flow heads), a nice set of cams, an edelbrock intake, and a centri blower.

If he sticks with the 2v stuff, everything is readily available and won't have to search around for anything. The 4v swap is not hard to do but can be a pain in the ass to get everything, relatively inexpensively.

CENTRI ALL THE WAY they sound amazing and make power... go with a cog pulley system with the F1A or the YSI

 

[Blkkbgt]

I voted KB 2.6. The low end TQ of a twin screw is nice on the street and should provide plenty of power. You can easily make 550rwhp and have room to grow.

I looked into tork tork tech kit with a whipple some time ago and honestly I don't feel it is worth the trouble or the cash.

Even though centris can make amazing power I am simply not a fan of them on the street due to the lack of low end TQ.

ive done the 4v swap twice. you buy a mark viii motor for 300 bucks and go from there. he would want sn95 cobra intake cams which would run him under 200 bucks and he could use the stock b heads which are great for boost just like the stock intake. headers, springs, and a tb would be aftermarket shit that you should get either way so that doesnt matter. the other shit is so minor and compared to the expense of after market cams and porting heads he would save money and make better power while be able to say he has an OEM top end

much more impressive then a cammed and ported motor

 

[redfire04gt]

what about machine work on those 4v heads? I would want them to be looked over before slapping those heads on any new shortblock.

To each his own but I don't agree with what you said above...a stock headed 4v is not more impressive than a 2v with h/c/i that was built by the owner rather than just slapping stock heads on a shortblock. Personally I would rather have my built ported cammed 2v motor over a built stock headed 4v with my same setup. Regardless if it makes a little more hp.

The 2v with a centri should easily get the OP to 6-700hp if setup correctly.

 

[redfire04gt]

I voted centri by the way. A D1SC would get you there. An F1a would get you there with less effort and give room to grow. Although, the F1a would be much more expensive to get setup correctly on a dedicated drive system.

Since you said mostly street use then a kb is the way to go. I may be biased a little but over 600 to the wheels with a kb is about as fun as you can get on the street

so a cammed and ported 4.6 making 600-700hp is more impressive then a stock top end 4.6 making 800hp?

:lol:

Depends on the way you look at things. I'd be more impressed by the work done to build the 2v to those numbers. Everyone knows its easy to make power with boost on a 4v. Not as many do it with a 2v. The underdog is always more impressive to me.

 

[froush]

yeah but a stock head/cam 4v with the same boost out of the same blower will usually put less down than a built, h/c 2v with the same blower and boost. The guy who got me hooked on the kenne bell had an 03 termi with a kb 2.2. He was pushing 18 psi just like me and on the same dyno with same timing made 570 hp. Mine ran out of fuel at 5500 rpm and i made 580 hp. I know numbers are numbers and thats about it but i feel like my little 2v in this case is way more impressive.

A well built 2v with the correct combo heads/cams will flow better than a stock 4v. But if the 4v does some work then obviously they will have the advantage

You said above to get mach 1/terminator heads. So which is it? Mark 8 heads or C heads?

 

[01SilverGt]

Whatever you do don't buy the tork tech blower over a centri or kb.

 

[blacksheep-1]

Although a KB fan, it still depends on what he wants to do with the car, the centri probably does make more power, overall, but unless he drives it in the banzai mode all the time I would think the KB would serve him better. I just drove back from the race at Road Atlanta (to Tampa) in my KB-2v, got 20 mpg with a 3.55 gear and the speedo rarely went under 80mph. I don't think you could pull that off with a centri. I drive the car often with all the accessories and a 93 octane tune, I have about 30Kmiles on the KB at this point.
