On the a31 turbs intake manifold they only have one vaccume outlet where skylines have two so you have to run a t section one to your B.O.V and one to your bosst gauge if you have one.

Interesting article...ive learnt something new.  Always wondered what that phsssssssss noise was when I quickly buttoned off the gas in the Cefy. Cant be to good for the turbo?  But than it makes you wonder why they didn't install a BOV in the first place if it was going to be that damaging to the turbo?

So are the auto skylines due to a smaller sized turbo, compare the auto turbo's wheels compared to a manuals ones! and late 1992 and 93 GTS-T manuals have an even bigger turbo again not by much though and im not fully sure but I think thats when they changed to ball bearing aswel. Its only the ceramic wheel nissan garretts that are not robust.
Im getting there slowly at the moment

come again?

a quick note on the difference in ecu's between gtst's and cef's/laurels.  gtst's use a 256k chip wheras the cef/laurel use a 128k chip

i cant belive this topic is still going.
