indivisible throttle body
 

Has anyone done an indivisible throttle body build?

I don't really plan on racing my 370z so I thought this might be a cheaper way to get some more HP rather then doing a TT build.

Any thoughts?

Individual tbs will end up costing far more than you think.

one nation, indivisible, with liberty and justice for all :tup:

Individual* Tb's will be about twice as much on our cars since we dont have a cable throttle setup. thats why they old 350z de motors could do them on the cheap

ahhhh

I was looking at ITB for a 350z, didn't think it would be to much different.

Thanks for the info guys.

Looks like ill keep saving for that TT. :icon17:

ITB $4K
Stand Alone ECU $2.5K
Tune and Other 1K

That's the rough of it.

That's a lot of coin for unknown results.

ITB for 370Z
 

Check into other car manufacture's (BMW-M series cars) that have ITB naturally aspirated induction. Bola (BolaInduction) now makes electric ITB for Chevy & Ford engines. If going the mechanical ITB route; Hilborn ITB comes to mind which will entail deleting the ECU controlling the engine.

You will need to know the flow of the cylinder head in cfm in naturally aspirated induction. I am not sure what the flow rate for stock 370Z cylinder head.

Good luck!

You will see greater returns with 4.08 rear end and tuning motor to 8000 rpm. Then spend time getting weight out of the car. Lightweight flywheel, aluminum hat brake rotors

But if you can't part with ITB here you go

Now what does that run?

$3600 for just this. But GTM will also be making a adapter to make it work with FI. But don't forget you will have to get a full stand alone ECU (roughly $2500+) and convert the throttle from drive by wire to cable. Super sweet.

Yeah that's pretty crazy

I thought those were largely pointless without a tuned plenum to house them.

Not sure I understand? No plenum is used. You have to tune each ITB to each cylinder.

that and your car will probably need a fresh tune every 2-3 months as the weather changes:roflpuke2:

It might. But stand alone ECU's can do a lot. Not sure

a standalone offers adjustability, but you'll usually get OOR between seasons.

Aggressive ITB setups work in places where the weather stays the same (like socal), but they're a nightmare in places with seasons

Meaning, I believe ITB's tend to work better (are easier to tune, yield more consistent idle, throttle response and power) housed within a well designed chamber rather than having each one completely open to the air.

That way you can pipe in cooler air (unless you have them sticking out of the hood), even out airflow, more easily meter airflow, more easily filter, and set up a more stable source of vacuum.

Like this Toda High Power ITB Surge Plenum Honda S2000 F20C AP1 S2K [17110-F20-000] - $1,370.00 : Real Street Performance Engine Parts, Pistons Rods Cams Valvetrain and More

or these OEM set ups at bottom

AutoSpeed - Multi Throttles

more stable source of vacuum? the plenum would still be before the throttles? vacuum is after the trottlesand if you hooked the map up to the lines they have there while it would still be more susceptible to pulsation it is still a shared reference to all cylinders. i agree the plenum would be nicer for maf and cone filters, and a servo box combined with a box to simulate an inverted referance from the servo spoofed through the ETB wires would let you hook it up to the factory car and run it DBW, maybe they are working on this?
