N/A cars that Have ITB's as standard

[SystemParanoia]

Just wanted to compile of list of cars that came from the factory with ITB's fitted by default.

i'll start with a few, but i know there just has to be way more.


MX5 - proposed


BMW M3


TVR's ( various flavours )






so... any more?

Toyota Corolla Levin......20 Valve Black top

With the exception of the North American market S52, all normally aspirated BMW M car engines have featured an indvidual throttle per cylinder, likewise the Z8 that shares the E39 M5's S62 V8 and also the McLaren F1's S70/2 V12.

Gonna be slaughtered for this, but anyway, can someone tell me what ITB stands for? I'll hand my PH pass back tomorrow

OK, I'm going to get slated for this, but what advantage do they have and how do they differ from other cars?

As far as I am aware, having the throttle plate as close as possible to the intake valves will mean a faster response as there isn't a few litres of vacuum (or at least low pressure) in a plenum for the air to get through first.

[Eighteeteewhy]

E24 M6

[thinfourth2]

Surely any single cylinder car would be in this list also

Alfa 33 16v, two sets of two ITBs

More power!!
Much more flexible and no compromise to the inlet side of things unlike a plenum chamber. None of the bodies are linked.
Just recently installed some on the 205 (see gallery)......did I mention the induction noise is unmistakable

190 upgrade for S1 Elise and Exige had ITBs I believe. Not exactly standard but available from Lotus.

My Caterham R500 has them as standard, and through the Pipercross Airfilter they make an addictive Induction noise.

Here is a picture when I was building the car:

The S1 Exige and 340R had ITBs as standard from the factory even with the 177bhp engine.
