Changing inlet manifold from 42mm to 50mm??

[Rhodri 0]

I want to change my inlet manifold from the standard 42mm to the bigger 50mm on my 2.0 16v.

 

Is it a straight forward swap or do i need anything else? I will be changing the throttle body to a 1.8 16v one which has been ported and gasflowed

 

Cheers Rhodri

Straight Forward Swap! But You can only buy the 50mm Gasket that goes between the top and bottom inlet from VW :(

Alright great stuff. Thanks for that. I wasnt sure if you had to mess with the injectors or not.

No, but they can be a total pain to remove if they have never been out!!!!

What a swine don't think they have been touched since the car left factory!!

gaskets cant be that much though can they . i should be doin this soon too

No not the gasket the injectors might be hard work to remove

gaskets are quite expensive, about £10 each i think.

Remove injectors when the engines warm, they come out easy then

so need a gasket in between top and bottom intake do we also need a gasket

where the bottom intake attaches to the engine ? the other thing thats i havebeen thinkin about is what difference would gas flowin the manifold would make . where would the increase in power be if any at all ?

cheers fellas

I flowed my old 50mm one, you prob wont feel any difference.

The head to manifold gaskets are the same whether 42mm or 50mm

Did you flow and port yours yourself if so is it easy because i just dont have the skills to do it myself if its difficult. :(

Would also like to change from 42 to 50 thou on my 1.8 16v
