Just curious if anyone has seen a 2.6L kenne bell on a mustang gtthat still had stock internals? Alot of my friends think that its not possible I on the other hand think positively... I think that running it a 9 psi and a good tune would keep it under 450 hp... I sure as hell am no expert (not even close to one)so how aboutgiving me some feedback on this...

Of course you could toss it on stock internals. (I think!)

But that sure as hell doesn't mean your engine is going to make it back home from your tuner.

Blower size has nothing to do with it. You are right. Keep it under 450rwhp, even around 400rwhp would be better.

Should be fine. With the Boost-a-pump and spark and a good tune, you have nothing to worry about.

The KB website is not recommending the blower for a stock motor car. I have a feeling this is because its simply too much blower, and your going to be way under the area where it is efficent running only 9 PSI on a stock motor GT.

In other words, the 2.1 will probably make more power at lower boost levels on a stock motor car.

+1 the 2.1 KB will give you all the power you could ever use on a stock internals engine. My 1.7 KB will give me in the 420rwhp range at 10psi once i get her tuned......the 2.1 has more potential than mine and is a great blower

nice mach 1 man classics will never go bad.

I have been looking at which KB to get also.... D'Agostino Racing told me that the 2.6 will be fine.. they are made for high hp applications (built engines) but they could through a really conservative tune on it and could get it down to as low as just above 400hp if need be. I am personally still deciding on which to get (2.1 or 2.6).. but either way you should be fine with the right tune.

You should also consider what exactly your goals are (and think realistically).... cost of the both units with install and custom tune are (and these are actual estimates that I have gotten)... 2.1 is around 6200 plus cost of any gauges you want... the 2.6 is 8300 plus the cost of any gauges you want.. plus a new hood (b/c the 2.6 will not fit under the stock hood)... and that is just to get around 400-450hp.. once you start to build up your car to take higher hp you are looking at basically replacing everything on the car to support it.. forged internals, tranny, clutch, axel, suspension, brakes, etc.. this adds up to a lot of money real fast.. b/c if you don't replace all that with beefier stuff to handle higher hp then things WILL break.

for 12# boost or less, the 2.1L KB would be a better choice... unless you want to buy my 1.7L KB kit. It worked fine at 12# boost (includes 8-rib pulley upgrade package). The only reason I took it off was to convert my motor to 4v.

Keep in mind10 lb of boost is10 lbs of boost whether you get it from a 1.7 or a 2.1 or a 2.6 blower. The diference is the size of the blower (will it fit under your hood?) and how fast you have to spin it to get the boost. The larger units are more effecient. You don't have to spin them as fast and they don't drive the boost temps up as high as the smaller ones. These are good things. I have had a 1.7 with 10 lbs of boost, intercooled, on stock GT internals for the last 15,000 miles on my daily driver and couldn't be happier. It's all in the tune!
