How to increase power?
Lumbering Jack:
Thanks for the help again guys,
Had heard the 3.5 mazda was a good lump, haven't seen many about though. before I bought the 130 i nearly bought an old ex military chevy pickup with a 6.2 gmc diesel in it but no-one would insure it sensibly [-X Friedn of mine has one and it doesn't even know it's got a 3 tonne compressor behind it up hills :twisted:
would it still mot without a cat or would I need to put it back on for the test?
Been on Allisport's website but it's under re-construction at the mo - anyone know what sort of money one of their intercoolers is?
I've not had any probs as yet with the veg, changed filter early on and have a spare ready for if I need it

A diesel does not require an CAT for an MOT.... it also doesn't need the EGR set-up.
The current 2008 MOT system for Diesel (i.e. compression ignition) vehicles only requires an Opacity test, (i.e. smoke) and not an actual emissions test as per a petrol (spark ignition engine).
A catalytic converter does not actively effect smoke…. This differs from a diesel particulate filter (which is also exempt from testing at the current time)
The only requirement is that the max smoke value for a turbo charged diesel is a mean (of the last 3 smoke tests) not exceeding 3.00m-1. For a initial 'fast pass' the smoke value must be below 1.50m-1.
In simple terms.... the only reason a modern diesel have CATs and EGR (along with other things) is to enable a manufacturer to meet the current EU legislation (for example EU4/5), but once a vehicle model has been type approved, and sold to the customer... the customer is technically free to do what they like regarding emissions, as long as they meet the requirements of their country, which in the UK is just the MOT test.
This can be confirmed by reading http://www.motuk.co.uk/manual_740.htm compared to http://www.motuk.co.uk/manual_730.htm
