I would suggest searching and posting on the American RX7 forum. Its far more active than this place so you have a better chance of getting a good answer.

Unfortunately every bit of useful info online relates to USA spec FC's, which got a whole different emissions system + electronic ignition etc.

I know that its to let air into the aft rotor when using engine braking to prevent pops and bangs. (Presumably because the stock ECU isn't smart enough just to cut fuel)
But I would have thought it would need an air source.

All the more reason to go stand alone to I can remove all this junk!

On my car the AAV solenoid (the yellow one) only has one end connected to the rats nest the other end is just capped off?

Is this normal?
On the vacuum diagram from the training manual it appears to be capped off as well, but why fit a valve at all if its going to have one side capped off anyway.

Can anyone shed light on this?

For some reason in my head I thought they were supposed to fit the front.

I'm searching for a car out there with the same as our front ones, it must exist. No way am I paying £50 each. (Which is what some fleecer on eBay has them at!)

Let us know how you get on with the Poly bushes.
I'm doing a full replacement of all suspension bushes this year, but I'm leaning towards standard rubber replacements which won't shake my teeth out.

Might be S5 only .. I should have checked when I was doing the rear brakes

I did make them fit the back anti roll bar though, so not a completely wasted purchase.
I had to grind off the extruding aluminium bushing to get the the alignment true, but it worked.

Would just like to point out that the Passat drop links are not interchangeable.
At least on an S4. Don't know about the S5.

Thanks.

I'll try without one first, given the engine has no lamda sensor, I can't imagine a cat lasting very long, the American one has extra air pumped in with the air pump, which of course I'm hopefully deleting.

Second question, does anyone run without the heat shield? The things an eyesore haha.

Great stuff!
It looks like the anti-afterburn valve has already been removed and capped off in the past, but taking the pump off should mean I can remove a load of piping from the engine bay and tidy things up a little.

From what I'm reading in the manuals I can find, I think the UK cars 6 port actuation system is activated by intake manifold vacuum so shouldn't be affected by the air pump removal.

Thanks for the quick reply!
I do actually have a somewhat friendly MOT tester who would probably ensure that it passed emissions wise, but I'd rather not have to rely that if I can.

I was thinking of stand alone, but I have plenty going on just to rebuild the car in standard form. (Although luckily no real rust found so far) so I think I'd rather get the car running and driving and then go megasquirt down the line.

I'll post up a build thread in a bit if people are interested in that kind of thing?

Hi guys,
I'm restoring an old FC NA that I picked up cheap on eBay last year, I'm still in the process of stripping out the engine for a rebuild, and I'm hoping that I leave out some of the emissions stuff and that awful looking reactor / manifold when I put her back together.

I've done a search but can't really find an answer, and a lot of info relates to the American version whereas our UK version seems to use an older emissions and ignition system.

From what I understand, I don't need a cat as it obviously never came with one, but I do need to pass my idle emissions test, so my question is, providing the engine is running well, can it pass this test with an aftermarket manifold and no air pump chucking extra oxygen into the manifold?
