thanks explains alot

but why is it not in my service manual is cause service manual is for a 4 port
sorry guys not to cluded up with 4-8port diff

Well it is one of those topics where you have alot of different opinions, there has been "tests" done by some forum guys somewhere that claims the 4 port flows better and therefore could give more power.....

Aperently the 8 port has better low down torque....

As for drifting use.....more torque down low helps loose traction so it is ok, but in my experience, if there is any delay or problem with the system it delauys your power sticking your nose in the ground and then pulls, this only happens when you change gears.....

My opinion, disconnect it or put on a 4 port head....

The only answer that I can think of is that the japspec manual is not availible on the net where most get theirs.....

no prob with it just saw it there and was wondering wtf it may be cos saw one on my cuz astina and got me thinking what mine used for thanks for the info draco much apreciated

Glad to help....

Again if you search you will find the answers you want.

Connect a vacuum line to it, it will give you more low down torque. Unfortunately the 8 port head wont flow as much as the 4 port.

All this means is you have an import engine in your car...

Just another tip.....obviously you have a imported motor in your car....make sure your papers show the same number, if not change it to the right engine number....otherwise you might find your car confiscated because of the wrong engine number....

draco dont worrie it all the same ive had the car cor and relicenced so all info is correct and nubers are same on my licence

gary it has a vacume line on it already there nuthing wrong with it just was wondering what it myt be and i would search if i knew what it was

how mus i search sumthing dont know what it is type funny thing at back of ca18det motor in google

that why i ask here for trusty info 😂 😂 😂

thanks for the help guys

also funny thing is my car is registerd as s14 i dnt know why when it is a s13 jap spec if you read this why did you register as s14

So was mine...

are cams on the 4 port and 8port any diff myt be dumb question but just concerning me

Cams are exactly the same but you can get the intake cam from a 4 port N/A JDM head for a power increase

is this a good mod and what power increase you looking at
plus where can i fine one from someone with a ca18de ( a sentra if im not mistaken)

i was just reading bout a 8port swop and says you must put oil cooler back does the 8port not have a oil cooler or what must i add a after market oil cooler

Ok if you sure the engine number is right, that's good, I baught mine, they put it thrue the test and all, about a year and a half afterwords I checked the engine number when we did my turbo and guess what....it was wrong!!!!!!

everything that has been asked in this thread has been covered thoroughly.

i urge you to use the search function and trawl through the information like most of us have already done. if you dont know what you are asking about, get a little bit of info and then go searching.

thanks.
