How to make an Activa CT perform....

[handyman]

Hello Gareth, I have tracked down a 306 XSi 8V inlet manifold and throttle body, so may be trying this on my test Activa. Will have a look at increasing the bore of the throttle body.

If it works well, will be after the 16V manifold for the Twin Cam head conversion.

Did spot a very nice four branch 16V manifold, but not suited for a turbo!

Hi Richard, would be interested to know the size difference in throttle body, maybe you could measure and report back? Also the differences in the inlet manifold?

If the throttle body is bigger, it should in theory reduce some of the back pressure and increase the boost. Is it a Solex as per the original?

Ever get a chance to do this?

I read the standard throttle body is 50mm and the XSi is 57mm.... i think it would make quite a difference with the matching manifold.

By replacement of the cat, do you mean complete disposal?

This bit of meaningless technology, the catalytic converter, has done more to make the internal combustion engine burn more fuel, than would have been the case if manufacturers had invested in other forms of technology to improve combustion. Just a cheap quick fix.

As an aside, the idiot who developed the technology, whose name escapes me, has only recently died. He was an American.

actually the catalytic converter works well, where it does restrict our power, the actual emissions reduces to a level that 1 car without cats = 100 cars with cats, that makes me still run cats on mine, or I feel like in a way i am killing the combustion engine by putting its emissions up. they sound so much better than hybrids and that whiring electric motor



good articles on the engine, pity the turbo isn't flanged generally, same for all peugeot's with the same engine too?
