How can I make it faster?

How can I make my 4.7L V8 a lot faster?

Turbo Charge Kit?

Is it possible to put a turbo charger into WK gc 4.7L?

Contact Nick from my sig for Performance parts. And, take a look at the Speed Freaks forum at www.jeepsunlimited.com/forums. Be prepared, there are a lot of very immature Grand drivers there.

As I tell everyone that asks these questions....and nobody likes hearing it-- but it is a severe reality....

What have you done to make your rig STOP better? Vented brakes, pad upgrades?

BEFORE you do any upgrade to make it go faster.....it may sound absurd but it just may save your life...... MAKE IT STOP BETTER!!!!!!!!!!

I don't think anybody makes a specific, bolt on turbo for the 4.7L or any other WK, but you could check out STS Turbo. I think one of their universals would work--I think there have been some guys putting them in WKs...

I've used www.stillen.com for X-Slotted rotors on my WJ. They should have several sets for the WK. -They are a little pricey.

There is a supercharger for the 4.7. It'll run you about $6g though... Can't remember the website, let me see if I can find it

HO Cams, intake, performace exhaust. Kolak is a good resource for you.

edit: KRC Performance - http://www.krcperformance.com/krc/in...hk=1&Itemid=26

They have a lot of other performance stuff on that site as well.

What else would I need if I got the stage III on the universal STS Turbo? Intercooler?

You may consider a good intake and exhaust system. AirRaid makes nice setups with TB spacers. I used to have a similar setup on my 4.7 WJ. -Definitely noticed a difference in performance. Good NA upgrades will make a big difference in performance. If you turbo/SC it, make sure to post some videos!

P.S. Don't forget about that extra 50lbs under the boot.

Whatever you try for your engine, call Kolak. If you haven't done that, you're making a mistake.
