4.7L Performance Upgrades?

I looked around but couldn't find any threads that summarize the best set of HP/Torque upgrades for the 4.7L Gen 1 motors. Specifically the 2002. Anyone have any suggestions?

 

Headers

 

get jba long tube headers, throttle spacer. good free flowing exhaust to start

It depends on how much you are willing to spend, I am enjoying my JBA short tube headers, LSD, and rear sway bar. Decent power gain, and much better application of total power.

 

Well then. It appears that Dirty Deeds is in San Diego. And I'll be damned. So am I. Gonna give them a visit.

 

Yes, visit him. Ask for Keith.

 

Switch it out for a 5.7l

 

Turbo kit. It looks like a good deal. Just run max 5 psi, and it should be fine. https://www.ebay.com/itm/4-7-Toyota...oC5xBDPztS4bsujQQjNpj4_m0kfsd7qavNpYvj364BI3g

 

Why? Swapping for an LS is a third of the cost and makes more power.

 

What is ‘LS’?

 

It's a Chevy motor, you know the American brand with the French name? I believe it stands for "Le Shitty"

 

I'd stick to the UZ family. Swapping may sound cheap at first, but it'll open up a can of worms and may not be cheap at the final stage.

 

Love this, but I'm in California so it's a no-go. I'll probably just go with long headers & new exhaust.

 

LSD = Limited Slip Diff? Is your truck a 2WD or 4WD? Mine's 4WD & so far I've not felt need to add LSD too. Hell, I barely have oppty to use the 4WD. Lot's of long nasty dirt roads in Baja, but not much of a rock climber (at least not yet).

 

Remote turbo setup?

 

Long tubes aren’t legal in CA either. Only for off-road use.

 

Wouldn't show up on a visual inspection.

 

I know recently they got a little more strict. But now they only hook up the OBD. But still walked around my wife’s car making sure. I had to remove her Volant intake as it’s not CARB legal here. And on my previous truck they were looking underneath making sure I didn’t modify catalytic converter‘s.

 

You can have Keith from DD to create mid pipes for you that would pass emissions.

 

For you in Ca, install the turbo, and remove it every 2 yrs for smog check. Lol.

 

Doing a google search for Phab, all I found was Amazon and EBay ads for the one above, and a number of posts in Jeep forums either loving or hating it. Do we know anyone who is running it?

 

The kit in the installed pic at the bottom isn't the same. That turbo is from Turbonetics and its aimed in a different direction. If they're using pics of somebody else's work as an installed pic that scares me.

 

I guess I need to start a thread about California Legal Performance Mods eh?

 

Sure. You can title it "Behind enemy lines".

 

Denso 12 hole injectors for better mid range power/torque and higher gear shifting points.

 

I’m running that kit above. You can find my build by googling turbo 03 sequoia. Should pop up. I go over some of the good/bad stuff.

 

4WD, and the LSD is great for added traction while in 2WD.

 

If you really in cali, then you can't do shit to it.
buy newer 5.7 is your only option.

 

Still a few things he could do. Gearing, 12 hole fuel injectors and coolant throttlebody bypass mod. I’ve heard the fuel injectors really make it nice. And gearing always makes the truck feel good.
