Turbo +/-'s

Yeah ^ I heard "Ceramic bearings" in the turbine help it spool quicker and assist with eliminating lag.

I like the idea of sequential turbos. Smaller one spools fast for take off and the bigger one takes over at higher RPM.

ok this is 2 evry 1 with a TRD supercharger on a V6 isnt it only 4lbs of boost and is it really worth it and wut can u beef it up 2 and the engine can safely handle , also i have a 4 spd auto so still worth it?

If your asking about the supercharger, then I doubt anyone would say it's not worth it. In other words, its really worth the money!!!

Parke10, I would say yes, even 4psi is worth it. I also have an auto V6 and was very happy the day I got blown . Check out my CarDomain page for more info. Until you do a fuel system upgrade including an EMS, I would leave it at 4psi. TRD messed around with this for a while and that was their safe limit for 91 octane pump gas.

You should look into the supercharger upgrade kit from URD. It includes all you need to bring it up to 6-7psi. From that point, you really need to do some serious engine work and decrease the compression if you want to take it higher. -JoeB

wut all do i needa buy for the fuel to ugrade to 7 or 8 lbs if any1 has already upgraded theres and got a good price plz tell me where and wut i needa buy thanks

That's what I was trying to tell you. Check out my CarDomain page, you'll see what I have done. The sc and the URD sc upgrade kit will get you to 7psi on 93 octane. I also have water injection and am getting 9.5-10psi effective pressure measured at the sc housing. -JoeB

doesnt water injection hurt yer pistons ,wont it pitt yer pistons

No. All the heat inside the sc absorbs and vaporizes yer water that you put in.

It's actually the exact opposite. They say that have run water injection, when taken apart, look like they've been steam cleaned. Piston pitting comes from running too lean a mixture. Detonation causes the pitting and water injection significantly reduces detonation. -JoeB

so even with 4lbs will it still blow the knock sensor?

No. You should be fine at 4 lbs.
