You'd have to be mappable management too, so you could go the whole way and fit tbs/management.


That's wrong on both counts.

Carbs won't make the car fail an MoT if they're set up right, the same as fuel system, if you have injection set up badly it will fail, but get it right and it's fine.

A X14xe conforms to 1995 on emission rules, i.e. needing a cat to pass.
With carbs you can't run a cat, and carbs cannot fuel as accurately as fuel injection(just because of the way they work, mechanical), so carb engine emissions are always higher, and it will fail emissions if the engine is fitted into a Aug 1992 on car.

Trust me, i had this problem on my cousins corsa sport when he wanted fit T40 dellortos to it.

Ignition management will need to be mapped to get the advance curve, and idle advance etc correct if you dont want to melt your engine.

still cheaper and easier to gte an inlet management. And you will see the same gains!

Management... You don't need mappable management for carbs, you need ignition management, that controls the spark using a trigger wheel, it doesn't even need connecting to a computer, costs about £100, I'd like to see DECENT fuel/ignition management for that...

better off with gettin a lexmaul or mantzel inlet than running carbs on an xe. no point making a new engine run on old upgardes. I would say a good inlet and map would get you more gains than carbs. Throttle bodie are a different story though!

only thing is you would need some sort of after market management to run the ignition, there was a total vauxhall article about fitting r1 carbs to smallblock xe's had some prices aswell

reading daz's thread about carbs and was wondering if i could get carbs on my sport?

what sort of price/power figure will i be looking at or would i be better to get a mantzel or similar?
