These are listed for the G35/350Z, but I think I read on here that they use the same heads as the FWD VQ35's. I'm not sure if they'll plug into our harness or not. Has anyone else heard of these?

if u look at the application charts, its available for the max. for $995, i will let someone else test them..lol

If you think you need more spark voltage, you can keep your stock coils and use a $50 DC-to-DC power supply and raise the voltage to your coils from 15 volts to 24 volts, and you just need to tap into one wire.

I used this quite successfully to spray 150-shot to my old 3.0, and I opened the spark gap back up to .035 with no misfires. I have the same setup on my 3.5 today, set at 15 volts - no problems...

I use the PST-P90W power supply. $48.75 each plus shipping.

I thought you were running it on 16v.... Ive been running mine on 16v no problems lol.

And Im boosted with 8psi, yet Im still running .41 gap with no spark blowout

Nope, it's 15 volts at the moment - but I'm not spraying yet. Then we shall see. I do have 1-step-colder copper NGK plugs installed, set to .035 for the future.

Glad to hear the Boosta works with your boost (heh) that's actually quite a gap for 8psi, isn't it?

Whoa, You can use a laptop DC toDDC converter to boost spark? This is the first I have heard of this. I'm going to have to search the threads to find the procedure.

Yup - I did this - maybe 2 years ago - to get enough spark for my sprayed 3.0. It's pretty simple to install - there is one common feed wire for all the coils going through one of the connectors up by the battery. It's listed in the FSM.

The power supply has some connectors for IN and OUT - cut off the connectors to get to bare wires. There is one pair for IN and one pair for OUT. Connect the ground wires together and connect to the battery (-) terminal. Once you locate the red wire going into the connector for coil power, snip it and connect the power supply IN (+) wire to the harness side and connect the OUT (+) wire to the connector. Set the slide switch to 15 volts initially, and your car will start right up, if you get it right.

Be sure and protect the power supply from rain water. I mounted mine in front of the battery, where it's easy to change.

Need more spark? Set the output to 16 volts. This power supply will go much higher, but your coils might not like 22 volts.

I've had it for just over a year (thanks to grey! ) with no problems at all. And I've been running it on 16v since day one with zero problems.

BTW,

AllMotor- gap was at .49 with no problems
8psi- Gap is at .41, again, no problems
