View Full Version : big port head
right,
im about to put a big port head on mine as my stem seals are shot so its a good time to upgrade.
what will need changing on engine? if anything?
am i right in believing map will need adjusting
ta very much :)
Your standard inlet manifold wont fit.
I dont think the map will need changing tho.
good point phil...didnt even think of that! cheers
i think it will fit just its not big port!?
can anyone confirm it wont need mapping?
I'm keepin an eye on this thread as i've got a spare large port that i'm building up over the winter months.

007 being the proven best flowing big port mani with r32 throttle body
cheapest quote i got for t'body is 175+
007 mani is approx 499
This might sound like a pathetic question, but whats the build quality in the 007 like? As i'm after a bit of engine bay eye candy i want something that not only works well but looks good.
Gay i know. lol.
Neh shouldn't need mapping but for max benifit you should.
Just got my car up and running there with small port head ported and polished. Port sizes comparable to a std largeport.
Everything seems fine after 42 miles touch wood :)
You'll need a full head gasket set.
Is the large port head VVT?

Any head can be VVT, you have just gotta put the bits in! Get rid of the VVT as its known to cause ussues.
Mine hasnt got VVT.
Decent head bolts?
its a ported out agu head
get a big port head and a big port 007 intake mani with r32 TBhave you got all this then?
have you got all this then?
no but if and when i upgrade my intake manifold this is what i will do!
would i need ibiza cams or the large port cams?
cams would be similar spec anyways not a great deal difference, not like lumpy rally cams.
But if youve got a large port head on it then more air will be entering as well as the tb your getting so more air = more fuel reqd so to get it running correctly without runing too lean you should get it mapped bear in mind the the air mass drawn will be greater.
is the ex port and int been enlarged???
then yes it will need mapping. you got bigger maf on?
also change your dv to the cold side
ive been meaning to do cold side DV
how cum you siad i need it with big port?
currently have 3" maf
its better with both small port and large port as it doesnt disturb maf to run weak causing it to burn out
currently getting hunting idle. been told its due to not having cold side.
that sound right?
