2004 3L Started...Questions

[mosh]

I have a 2004 3L on my garage floor to replace my recently deceased (well damaged beyond economic sense anyways) ported 3L.

I loved my ported motor, but this time I'm going full 3L, with the possible exception of SVT cams....agonizing over this and examining every dyno and comment on the board. My rev limiter is at 7500 and I'm used to hitting it regularly. Can I live with shifting at 6300?

Anyways, I need a couple of quick answers from anyone willing to share:

1. How do you deal with the 2004's larger coolant outlet from the water pump to the crossover? I have my 2003 water pump too, but if I use this then the problem switches to the outlet to the block.

2. How can I adapt my 65mm TB? It looks like the IAC inlet is part of the 2004 TB.

3. I've ordered an NPG fuel adapter. I have 2 Taurus fuel rails, an 03 and an 04...which is better?

4. What is the easiest intake accordian to use? From my initial exam, their will be no need for an IAC connection and only one PCV. I usually custom mount my IAT.

Aside from this stuff I think this will go quick as I have everything I need at hand. Thanks in advance.

1. use the waterpump that is on the engine. no need to change the waterpump as the 3L one should be pretty new (depending on enigne milage).

2. no clue.

3. no idea. if the engine is an 04 I would just use everything from that engine.

4. could make something custom with pipe. or maybe get a NPG cold air intake?


and personally I like the SVT cams. in builds that are done locally everyone swaps in the SVT cams or they have gotten SV cams.

Thanks...nix the water pump question...on further inspection the hose fits fine.

Another question: What do you do with the two metal vacuum ports integrated into the bottom of the TB?

1. I just used the water outlet setup from the 3L engine and modified the rubber lines. For me it was a 2002 but you could still use the stock 2.5L setup and be fine. Many have.

2. Depends on the UIM. Any 2.5L UIM swap has the IAC run through it. The plastic 3L manifold has it in a different spot but still through the UIM. Are you confusing the EGR ports? If so just make sure the gasket seals well!

3. No difference. Pretty much all returnless rails are the same. Actually the earlier 2.5L setups seem to have bigger diameter though. Not that it matters for any sane horsepower build. (sub 500 wheels)

4. Build your own hard pipe or get a solid silicone piece. (which still means some custom fabbing) Single feed the valve cover vents. make sure the PCV DOES NOT tie into any other feed. Make sure the emission's feed (evaporative system) from the fuel cell is not exposed to outside air (i.e. leak) or the PCV will stick open. This makes it suck in crankcase air all the time. (i.e. oil vapor!)
