Wouldn't a VQ have lower emissions than a boosted SR? or am I missing something here?Q45tech wrote:Why would ethical people consider violating the Federal Clean Air Act by installing a larger displacement engine?
^^^^^ these are the people that are involved in the EPA that are the reason we cannot update our refineries, build newer more efficient refineries, and dig for oil in our own land..... These people are the reason GAS is so freaking high.... federal clean air act.... blah blah blah..... the same people that say diesel is more polluting than unleaded.... Diesel is more pure and easier for the earth to break down, but since its black smoke it must be bad.... only in america!Q45tech wrote:Why would ethical people consider violating the Federal Clean Air Act by installing a larger displacement engine?
Useful! I had been looking for a breakdown like this! Does anyone know if Rev-up heads bolt on to Non-Rev-up FWD blocks? And does the HR intake manifold bolt on to Rev-up & non Rev-up heads?SPiG wrote:Between the FWD and RWD VQ35DE (not including Rev Up, HR, or early pathfinder)
these are the same:pistons (compression is the same for all at 10.3:1 from the FSM)rodscrank etc.heads everything inside the heads including cams and VTC
These are not the same:Block (mount oil panintake manifoldexhaust manifoldscoolant linesheadgasket (FWDs have 2 layer, RWDs have 3)
All it really does is make you source some more parts like the oil pan and IM, and make custom motor mount brackets. It can be done and for significantly less money than a RWD engine would cost.
The Nissan VTC on the VQ35 is continuous so it is NOT on/off, and cannot be controlled without a complex computer to run it. There are ways around it including disabling it, but you will lose torque or have to use the stock ECU or an expensive standalone.
I am personally disabling it for my swap since I think I will have enough torque with what I have planned.
Darn, I was hoping that would not be the case...tre4s13 wrote:Plenums are obviously different....pathfinder, 350z, maxima...etc
But after comparing the 350z manifold to the maxima manifold per fsm....I noticed they're perfectly the same from head to gasket to manifold...BUT from manifold to plenum there's a difference in the top for the runners....maxima is circular, 350z is square.
The maxima has 6 circles perfectly inline with each other...
The 350z has 6 staggered squares......
Bolt holes are nothing the same.....
So it's safe to ASSUME that you can use ANY plenum with its corresponding manifold to whatever vq.
