ITR intake into b16a

**shurman** · 07-04-2006 06:53 AM

i am a noob and what im saying is logical to me but... as i said i am noob.
if 'i' fit a ITR manifold with a bored 70mm TB and add DC2R injectors and fuel rail and regulator. more fuel + more air = power??
and 'i' had a power fc tuned properly, with a decent exhaust (header/cat/catback) would 'i' make more power/better torque??
please dont noob bash... im learning over here

this should be in the newbie section

im sick of people thinking if i put parts from a better car into my car it would automatically run just as quick.

its a pretty good question... stop noob bashing this poor bugger

its like asking would CTR cams give gains on a b16a.

but im sure if u search you would find the answer to you question

the ITR injectors are the same 240cc/min as a B16.

You will gain absolutely nothing in replacing fuel rail.

Larger Throttle Body & Intake Plennum will cause the intake charge velocity to DECREASE, regardless of more air volume coming in.
Net result will be less response early throughout the power band, with possible gains up top.

It's not as simple as more air = more power!

the stock fuel system for the B16A is fine for an internally stock NA engine.
even with tuning, without having done any headwork or internal work, the ITR manifold and a 70mm TB is unlikely to give gains on a B16A.
like i said earlier, you're better off spending the money on many other things first.
the IM is a modification which you shouldnt be considering till much further down the track.

The long rod combination of the B16 does not lend favourably to slow velocity intake ports & large volume intake plenums. Hence the reason for cam overlap.

The B16 needs high velocity to make early power, hence the reason for the TB & Intake manifold sizes.
