OEM D-Series Intake Manifolds

when the last time I lay 2 sets of injectors, I saw a small difference in the contacts.

Your difference in contact is the difference between OBD1 plug (left - D16) and OBD2 plug (right - D14).

The difference between 190 or 240 cc is in the tip color (you have to remove them from the IM to check!). If the tip is green-blueish (exact tint changes over brands and models!) you have 190 cc. If the tip is more orange-red-brownish (tint changes as well), you got the 240 cc. And that is the same for both OBD1 or 2.

I've got them lying around in my room so I thought i'd take pics....
Connectors

It does'nt look like there's any difference here...
Colouring

Like you described Joris

So i have 240cc (red) and 190cc (blue).
Possibly the 240cc where of an OBD2 d16??

[ilya]

ok next week i will make the d16z6 IM swap to my d14! i have 50mm exhaust and simota heat shielded filter saxophonias had... i want to ask you, i am gonna to see a difference in power?? maybe 3-4 hp more???

[Law_]

you should notice the difference. not talking in figures ! but the feeling is different at least for the D16Y8/D15Z6 manifold

You will just need a need TB and IM gasket for fitting.

Hi all

Just wanted to ask which gasket to get for the TB? I'll put a stock D14A3 TB on an IM from a D16 (dunno actually if Z6 or Y8 it's from an ESI if that helps). I'll go an order the gasket but I still have the D14 TB on the car so couldn't take a look if it's any different to the D16 one so wanted to ask you guys if it's the same or which one should I order.

Thx

You should order the D14A4 TB gasket not D14A3 as it is restricted (hence the 15 more horsepower on the A4). For IM gasket use the one that fits the manifold, i.e Y8 manifold use Y8 gasket, etc. They should all be pretty close though.
