intake manifold

Whats the difference between the following 2 manifolds? performance or just looks?

Just 2 note neither of which is my car my mate just sent me sum pics, but i have both manifolds. And he also sent me a 3rd pics of sum independant throttle body which i cnt afford 2 do, so out of question but will post 4 u all 2 c.

the top pic [cultus manifold] is the jdm inlet manifold and flows better than the stock one the second is stock uk gti the third is alot of money as you will need managment


steve

can u just change from uk 1, 2 the jdm 1 or do u need 2 change allsorts?

its pretty much a straight swap, get it bored out to 60mm while its off the car, just incase you decide to change the TB later on

yea yo can and it helps if it comes with all the genuine brackets and what not

I have 3 engines with the uk type manifold and 1 with the other. I've read alot about the fuel rail's been differant 2, is this true and also is it worth changing?

Also wot is there any difference between a K reg motor and a N reg? is there any?

Thanks John

The MK3 fuel rail has the fuel return lines on the outside and the MK2 has the return on the inside of the rail... MK3 better flow.

Only really an issue if you want high hp.

If you have a Cultus manifold then its worth changing as you will get some gains + they look better. Or sell it as they are worth £££.

There are a few little differences between the UK GTi MK2-MK3 engines.

The fuel rail as above, plenum accessories Pipes/valve's..., Cam cover breather holes... some have hollow cams.

R the hollow cams better/lighter? can u tell by taking the cam cover off or do u need to remove them?

just take off the cam cover you will see there are holes inbeetween the lobes they dont really make a difference
