Hi guys, me again!

Now I've got the exhaust sorted (and soon to be manicat), I'm after an uprated inlet manifold.

Been looking at the Dbilas Inlet, it is however bloody expensive!!

Researched the 2.4 option, this doesn't appeal to me.

What other options do I have? Car is a Vectra C.

Thanks in advance for any suggestions.

You could get rid of the egrvalve with a egr cheater and blank it off.
and i tried the vw polo mod described on this thread
so you get rid of the steel pipe that goes in your inletmanifold under your throttlebody.
i noticed a much better gasresponce and a better stationar running engine.
just go to the vw dealer and ask them about the plug they wil probally have them in store, very easy mod .
and porting and polishing your throttlebody is a good mod 2.
And meaby a k&n replacement airfilter?or other brand filter wil help to breathe better.
and get the small conepipes out of your airfilter box.

just my 2cents what i tried thanks tho this forum :p

Cheers for the info so far guys. I'm going to purchase the EGR cheater and blanking plate.

Still not too sure what to do on the inlet side. Might just go for the 2.4 inlet and forget about being able to remap the engine
