Has anybody ever tried this mod on the V?

The engine will run like garbage if you did this.

Any particular details you can give on this? Like, perhaps, why?

Advance timing refers to the ignition timing. When you advance, it lets the spark burn sooner than the time it takes the piston to get to TDC, thus having a longer burn, more combustion, more power. The only downside is knock. So to compensate for knock, you have to run higher octane fuel. But the process of doing this correctly involves messing with the TPS sensor which can result with incorrect idle speed. The service manual should indicate the degree tolerance specs of the ignition timing, shouldn't be no more than 1 or 2 degrees. So the only benefit from this is a very slight increase of throttle response, so it won't do wonders. And at the expense of risking engine damage in terms of knock and pinging and spending more on higher octane, its not a good mod.

Im sure somebody will try this out and be the guinea pig, hopefully

Even I'm skeptical doing this mod myself, there's a bunch of guys on another forum who are doing it. Some are already experiencing knocking and weird noises from the engine, others aren't.

If you use nitrous you retard timing

How do you even advance the timing? I know in older cars you can just rotate the distributor a bit. Stock is usually about 15 degree and people would bump it up to 17 in the 240's and other older nissans. Usually neeed to run higher ocatane fuel to prevent knocking. On a V with no distributor how do you even do it?

This was done on my 240 but I didn't notice enough of a hp gain. Not something I would bother messing with again.

 

[Hschlick84]

If the V has no distributor, then I'm not sure. I can look through the service manual and check out the section it's located.

You have to bring it to nissan, unless you have a standalone

What would they do (speaking intentionally)

 

[robj80]

Nissan can adjust the timing with their consult. It's all computer controlled unlike the old school days. I highly doubt nissan will actually do this for a customer though.

 

[android49]

Lots of Spec-V guys get it done at the dealership actually. Most of the time its to retard timing for a turbo or high nitrous shot. I have heard of N/A builds advancing timing though.

 

[Hschlick84]

On my car, there is a distributor bolt that can be adjusted about 5-10 degrees CW and it can retard the timing significantly.

On topic, Nissan can do this if you request them to on the V.

IF you do this, then you MUST burn premium, or else blow your motor.

 

[Hschlick84]

You could use at least 87 octane, but that's really pushing it. Best bet is to keep it above 91
