So everybody knows that one of the best, and most expensive ways to make big power gains is forced induction. But i like many cant afford a 6K supercharger setup. I have done a little homework, and and i found a solution. Independent Throttle Bodies. This set up is basically the equivalent to a low boost supercharger, when properly tuned. The only issue is that he only v8 setups i can find are for chevy. My question is, does anybody know of a ITB kit for the titan, or a good fab shop that can make one?

i think those are being run on the 350z wit hthe vk56 in it .. i belive its the drift car .. can anyone else ring in on this
:google:Individual throttles allow high speed throttle response and increase in power by reducing pumping loss from a conventional intake system.pedalhappy1053 said:

Yeah it looks like a great idea. So theres a throttle body for each cylinder? What do you do with the intake manifold? You still use it? OK OK OK I should use google
it really depends on the kit you buy. some come assembled with a manifold, and others just bolt directly to the head
I found one!

your guess is as good as mine for injector size

Yea the air is hot but if you think about it when you buy an intake all you get is smooth pipe and a filter. this creates less resistance and allows more air to enter the engine, allowing it to be more efficient, creating more hp and tq numbers. An ITB setup is the same, just on a much larger scale. now, instead of having one source of air split for eight cylinders, each has its own sorce of air, allowing much more to be delivered to the motor creating more power. so i guess if you think about it, its like a turbo, but instead of having a turbine to create a vacuum, the motor is using the vacuum it already creates, but it is essentially stronger because the air does not have to travel as far to reach its destination. Now dont get me wrong i love forced induction as much as the next gear head, but its like the saying goes, "their is no replacement for displacement."Toomnymods said:

yes you still use injectors because the motor still needs fuel. if you check out the pic above you can see the fuel rail still attached. as far as tuning it, you would have to take it to a dyno for a few pulls, and a reflash would be in order to take care of the air flow sensor i assume. im still researching it, but it looks like some modifications would have to happen. if anyone knows for sue please chime in. anyway hope im explaining everything clearly
It would have to be converted to MAP based intake mass flow calculations. I don't know if our ECUs will listen to MAP only readings for load calculations. Well, you can run a single maf to a single large volume plenum and still get itb benefits or a dual plenum setup etc. But, most ITB setups use open air "velocity stacks" or "trumpets" for the best gains. Who knows... good luck if you try it!
Yea i really want to but its looking like this is something that i would need to take my truck off the road for a while to do, and sense its my only ride, its gonna be a while
There is an IBT set up for the Titan and I've personally spoke with them. Man it's been so long I don't fully remember the conversations.
going from memory.....the ECU in the Titan is completely replaced. You need a new fuel pump......all the throttle bodies....rails...it was fairly expensive.
And unless you put an agressive cam on the truck with the valve springs to go with it you won't reap the benefits of a high reving IBT system. Cause you'll want to bump that rev limiter to 6500 to 7k.

And when your all finished with it.........you can let me borrow it :upsidedow
bleh why cant these idiots do a turbo setup, that is what most titan owners want to see, i want to see this trucks motor pushed to the limits.. screw a 30 hp gain, go for 150-200Nismo4life said:
if one of these guys would do a turbo setup, we might get some help from the aftermarket folks for cheaper pistons/c-rods etc..
that is the only reason we have cams is because of chris forsberg, if he wouldnt have wanted them we'd still be under 310 rwhp
well if you want why dont you fab one yourself, along with low compression pistons, rods, springs, not to mention all the other stuff you need just to prevent engine detonation. and have you looked under the hood of your truck lately? not a lot of room for piping and an intercooler is there?
Nismo4life said:
lol PLENTY OF ROOM, with a turbo you could get rid of the airbox and it's piping, also could re-locate the battery to the underside of the bed, thier is a ton of room for a twin or large single
and believe me i will have a turbo truck within the next year, just need to pay off this tranny i just had built the total cost of it was nearly 6k with labor, i figure if i'm already in 20-23k on my truck already screw it what's another 10k to finish it off with a built motor and twin turbo kit
