Modify question .......

Can i use FD intake manafold on S4 engine ???

Because i m going to port my N/A engine and put a TD07 in it.... and i need to spend a money on intake parts..... I m thinking it is possible to do it, and i m thinking should i use FD intake parts or FC turbo intake parts , if possible fitment ???? thax

 

From what I understand mazda put alot of research into the stock manifolds and they flow best. From the results of swapping intake manifolds it was proven that there are no reliable benefits from doing it.

You should be able to port them out a little

Besides... it wont fit

 

Yes they fit. FEED makes an adapter. Use the search button you will find a great thread.

 

thax guys..... cuz i don't want to use my stock n/a intake, i need the FD one for it..... plus i m going to put an intercooler on the car , so i think FD intake is better

 

For n/a manifolds? You have a link for this? I'd like to see it.

BTW, What are you looking at as your budget for your turbo install? I'd be interested to see how it balances out vs. a full swap.

 

This will not fit on a 6-port N/A intake manifold with a generic adapter. You would need at least a 3 inch tall adapter to make it work, not to mention input for secondary injectors.

However if you may use a small adapter to make it fit onto an S4 or S5 turbo lower intake manifold.

 

Put a film of vaseline on both sides of that new gasket when you put it back on. Or put a film of red rtv on the removable part to ease later removal. DON'T use any *glue* type adhesive when you reinstall the gasket.
