tommyboy Posted August 21, 2007 Share Posted August 21, 2007 I just bought a 60mm 240SX TB to put on my N/A 1981 280ZX 2+2 and I noticed that there is only one vacuum hole on the TB, when there are several on my stock one. Well, my question is, do I connect the vacuum line that runs from the T.V.V. in my thermostat housing and my vacuum advance on the distributor, into that hole, or should I buy a piece of air tube and make my own vacuum hole on it? Actually, do I really need to have a vacuum line connected to the distributor? I mean, I know that it advances the spark when the engines cold (Under 131 degrees F.), but I live in AZ where it doesn't take that long for the engine to heat up. So, could I even take the T.V.V. out of the thermostat housing and plug the vacuum opening on the vacuum advance of the distributor, or am I TOTALLY wrong on this subject? BTW, sorry for such a long post.:mrgreen::mrgreen: Quote Link to comment Share on other sites More sharing options...
naviathan Posted August 21, 2007 Share Posted August 21, 2007 It doesn't advance it just when the engine is cold. The stock vacuum port for the dist is a ported vacuum line that only applies vacuum when the throttle is cracked open so it advances as the engine RPMs increase. Yes you need that.

Alrighty, so like I said, my TB from a 240SX (just got it) only has (what seems to be anyway) 1 vacuum port. So can I install the vacuum tube that's connected to the T.V.V. and the distributor to that port, and the other vacuum tube from the T.V.V. to the manifold?

naviathan Posted August 22, 2007 Share Posted August 22, 2007 Slow down haus...No need for the bold lettering. By the looks of the location that port will be a ported vacuum port and yes you use that for the dist. Quote Link to comment Share on other sites More sharing options...
tommyboy Posted August 22, 2007 Author Share Posted August 22, 2007 Sorry for the lettering, it's just that I'm car-less until I get everything back on my engine, and this is one of the last things that I need to do. Thankx a bunch for the help Naviathan!!!:mrgreen: Quote Link to comment Share on other sites More sharing options...
