ekupathy87 Posted March 27, 2010 Share Posted March 27, 2010 did anyone ever make a TB spacer for our 3.0's? i have been pondering whether or not this would help my truck, and I know someone who could make one, if i had a spare TB to mock one up. I just thought I'd ask first to save the trouble. Link to comment Share on other sites More sharing options...
MY1PATH Posted March 27, 2010 Share Posted March 27, 2010 (edited) somone did for their rig. I beive they said they could feel no benifit from doing so. I think they spaced it up to 1/2". I am also under the belief that a spacer used on a carburator style intake manifold is pretty much useless. What will benifit you is gutting out your mixture heater as that is a nearly useless restriction in the intake. and there are other good reasons to remove it... http://www.nissanpathfinders.net/forum/index.php?showtopic=25383&view=findpost&p=469472 Edited March 27, 2010 by MY1PATH Link to comment Share on other sites More sharing options...

GrimGreg Posted March 28, 2010 Share Posted March 28, 2010 Yeah, 88 did make one out of plastic IIRC. He had a write up on it once upon a time. Link to comment Share on other sites More sharing options...
frecklecolouredbrain Posted April 1, 2010 Share Posted April 1, 2010 What will benifit you is gutting out your mixture heater as that is a nearly useless restriction in the intake. and there are other good reasons to remove it... http://www.nissanpathfinders.net/forum/index.php?showtopic=25383&view=findpost&p=469472 I tried this a while back and had nothing but trouble; almost like she was getting TOO much air. I suggest eku, that if you're gonna try this look at the mixture heater first. There were 2 different heaters between 87 and 89. One had 1cm spaces in the grid(like mine), and the other had 3mm spaces; so I think nissan figured out the restriction issue and corrected it.

Tungsten Posted April 6, 2010 Share Posted April 6, 2010 the main restriction in this engine is the size of the valves, they are very small Link to comment Share on other sites More sharing options...
MY1PATH Posted April 8, 2010 Share Posted April 8, 2010 the main restriction in this engine is the size of the valves, they are very small I disagree, I think getting the same ammount of air in there at a higer velocity is a good thing unless your trying to build a high rev motor. Now I think having a little more cam duration instead of a bigger valve would be more benificial. It seems the Heawork section at redz31.com give the same idea... http://www.redz31.net/pages/headwork.html#valves Link to comment Share on other sites More sharing options...
