KB 2.6L on 2003 Mustang GT 2V

codycat91 · May 18, 2012

You should be able to find a better deal anyway on a smaller blower that would be safer too

Guess I will think it over this weekend - by the way what would be safe boost to run with the KB 2.1L SC, heard 9-10psi but nothing definitive

wicked96gt · May 18, 2012

Where did you find the 2.6L kit that cheap for! I want it! ha

Mustang Racer · May 18, 2012

IMHO I would get it. either run it at 9psi or save up for the built bottom end and then put it on but either way its a good blower and gives you plenty of room grow.

White03GTanger · May 18, 2012

So would I need to run a underdrive crank pulley if so what size and which brand, because the largest pulley KB has for the 2.6L will only get the boost down to 13 psi with the stock 6.5" pulley?

It will work just fine on a stock motor. Just toss a 9lb pulley on it and rock it.

You wouldn't need different fuel rails. The ones currently on my car are from a 2001-04.

9 psi with a 2.6 is safer on your motor than a 2.1 on 9 psi, ait's are lower and less stress spinning it

So i would still need: Injectors, Boost A Pump, throttle/cruise cable, and SC pulley (what size did you have when you were running 9 psi? 3 7/8")

Have a 2003 GT Auto with mods listed in my signature. I can potentially get a deal on a used KB 2.6L kit and would probably need to put another $1000 (BAP, Fuel Rails, Injectors, throttle cables, 9 psi pulley, spark plugs) into it on top of a tune to complete the kit. This option is cheaper than buying a new KB 2.1L kit but wanted to know if I would be alright running a 9 psi pulley on a KB 2.6L with a stock motor?

Thanks in advance

Off topic, have a video of your exhaust?

Is that a 2v specific blower or would you need the tork tech kit?

a KB 2.1,2.6 and 2.8 can be bought 2v specific (so can the 1.7 and 2.2 but KB does not produce those anymore)

White03GTanger · May 18, 2012

Shaun: Will upload video tonight or tomm, I love that sound, curious to see how it will sound with a blower.

Cody: The kit is made for the two valve, do not need the tork tech conversion

3.5" sc/6.5"crank, it's a 13psi ratio for a stock motor at sea level. Up here in Colorado with ported heads and cams I saw 9psi.

You will also need a bigger hood.

I wish I had your problem of wanting less boost. :lol

White03GTanger · May 19, 2012

So I will need underdrive pulleys, do I just need the underdrive crank pulley or should I get the kit with alternator and water pump?

Doesn't look like any place sells just a underdrive crank pulley

The guy I am getting it from used the stock GT hood and cut underneath the hood scoop to clear enough room for the SC

NO_PI_NO_POWER · May 19, 2012

Cool on the hood.

8 rib:
Innovators West 8 Rib 10% Underdrive 5.875"
If you want smaller they might be able to do it, but there might be a larger SC Pulley available also if hood clearance allows.

Just do it man, Run it till it blows:rockon

1sickSTANG · May 19, 2012

All depends on how much power u want , and how much you wanna spend, add 2500 for a forged block and run 550HP +. Run the 2.1 kit stay around 9-10 psi push 400rwhp and run it as a dd.
