ITR Intake Manifold on b16aII

**SiR JDM** · 03-02-2005 02:24 AM

Hey guys... done some searching and researching, few questions for those that know...

I got a decent deal waitin on a ITR I/M (TB not included) ... wondering mainly 2 things...

1 - Ive read and been told of different experiences with the ITR IM on b16as.

Most comon story goes that a bit low end is sacrifced for a bit of top end.... mainly interested in the extremities of this... b16a is already torqueless.. i dont want to loose TOO much, but if a top end gain is seen then i am willing to sacrifice a bit... whats the main story with this ?

As i havn't done my exhuast yet, i was thinkin if a low end is significantly lost id do a 2" instead of a 2.25" .. but that might be pointless as the mod will be done for the purpose increasing my topend ?

Also im planning on using my b16aII TB... which i dont think people used in these stories?

btw - to add im running, and plan on running all stock internals.. bolt on modifications only.

2 - Reading various info all over the place i have a fair idea wats involved..
Different IACV is needed (got this covered)
New TB and IM gaskets (no prob)
Relocating IAT - The IAT Sensor is differnent on the ITR so there is a hole... I heard the b16a one doesn't fit ? if this is true, wat should be used in replacement of it?
Read most other things fit but are a bit of a tight squeeze?

I've got a ITR I/M on my B16A and I've got no complaints. Though my mechanic seems to think that the CTR I/M works better.

But it was a good upgrade. I'd go with it.

I thought that practically the ITR and CTR have the same manifold? Although they have different part numbers, the runners are slightly shorter on the CTR and throttle sensor placement the differences are negligible.... so ive read.

Looneee - Which other mods do you have with it? Did you use the ITR TB as well? Any difficulties/troubles when you changed over?

I take it they are refering to Throttle Body.

...to clarify a few things...
IM : Intake Manifold
TB : Throttle Body
IACV : Idle Air Control Valve (Oftern refered to as IAC)
IAT : Intake Air Temp (Sensor)

EK9 IM = EK4 IM, internal diameters are all equal to 45mm, but the TB on ek9 are bigger than ek4 though, it's 62mm

SirJdm - i got a port and polishd ITR TB and to be honest with u i dont think u will notice the power shift cos its that small. if u already have the IM then bolt it on, if not then dont bother. another option would be to PnP ur current manifold.
