Hi guys, I am just lining up to pick up a set of Eisenmann heat exchangers for my 3.4 project engine.

The engine will be a new build, new case, Mahle 98mm's P/C's, DC35 cam, and PMO ITB's. It will have a full engine management system that I have not yet decided on (Motec, the new Megasquirt or similar) with CoP's, twin plugged of course.

I am planning on getting the Eisenmann's that are cut back to allow a pair of catalytic converters should I decide to go that route.

Question is, can you make catalysts work with ITB's or is the control too poor at idle and similar to make it work and keep the mixture stable enough to actually clean up the exhaust somewhat.

I am not looking to make a low emissions vehicle, but since the car may well end up in a controlled jurisdiction in Europe, it would be useful to at least be able to pass emission tests for the year of the chassis - 1989.

Any thoughts or knowledge would be great!
