Lets Talk d-series

[~Sp33~]

Same engine internally, only minor differences with things like flywheel teeth/clutch etc.

Those things are year dependent not because it's a ZC, same thing happened with the D

And this is why I always tell people to message you with their D-series questions

[ep3rsteve]

slightly related...anyone know if a EF8 b16 hi flow cat + exhaust system will fit/bolt onto a d16/zc EF7?

[seanizshort]

Ep3steve. The head won't bolt strait on. D series and B series have different manifold bolt thingys. Dosnt even fit. Sorry to bring bad news.

[trism]

but other than the manifold itself, ie from the cat back, yes it should fit.

[dougie_504]

But unless it's an aftermarket cat-back then don't bother. OEM one is small.

cheers guys... from the cat back is good enough. I've heard that headers from some integras are interchangeable?

older integras with a D series (d16a)....yes.....but why bother ?

Wondering if they were different/better seeing as there are no/hardly any after market options available. But all this is making me realise how untuneable the d series is. Still happy with it though lol.

if it hasnt got it - get a HD clutch and lightweight flywheel , such as a TODA. This will open up the feel and revs on the engine and make it alot nicer to rev out around town. Best bang for buck mod on a D series.

I disagree ben...a decent header for $120 would be the best bang for buck imo

Which does nothing ! (especially on a D series)
A flywheel , does not increase HP. But it increases response and will make your car faster in all aspects. So , putting $300-400 into a light flywheel , is far better investment in a $120 header that does nothing. Id bet the same amount of money on anything else...will not produce the same results or "feel" or "smile factor" to the owner/driver.
