when you buy the kit you get either a 91 or 93 map. I have no idea why they used 94 octane for this dyno. also keep in mined that aps is in australia. i guess they have 94 octane there.

 

It's happening now for the guys that are interested, contact Tuan at GRD in Chicago, contact@grdperformance.com

Thanks

Signing up. I wanna give YOU all of my money APS. Thank you for the hard work and completeness of your creation.

 

The APS single turbo system will be tested on the G35 overing the coming weeks and with some luck it will be nearly identical to the 350 Z turbo conversion, I'll keep you guys updated with info.

You don't need a Unichip dealer for the intercooled single turbo system install as the APS turbo system will be complete with a safe and powerful tuning map.

Happy boosting.

Peter

 

There's a really good chance that this will be the case, hopefully the same group of supplementry parts which upgrade the TT system for G35 will be suitable for the G35 single turbo system, I will let you guys know as soon as I have firm information.

Thanks

Peter

 

Correct and the APS single intercooled turbo system is not a difficult system to install (I reckon about 2 days for the average guy who likes turning a spanner) and there also will be a set of comprehensive and easy to follow install instructions and diagrams supplied, all good.

 

The air intake system is supplied as part of the APS single turbo system, an aftermarket exhaust system should have little impact on the AFR, we have allowed for this in the tuning maps that APS developed.

It's more likely that the VQ engine will need some additional tuning for high boost, bigger cams, lower comp, etc, etc.

Peter

 

I sure would love to see this kit fit the Sedan 5AT. Any APS tuners in Northern California that maybe willing to undertake such a project? Do you have any recommendation Peter?

 

This will depend on the fuel octane used and exhaust system performance, I'd say somwhere around 360/370 WHP on 91 octane fuel and up to 400 WHP on 93 octane fuel with a low restriction exhaust system.


I believe the ''pretuned'' APS computer will offer a good deal of engine safety and piece of mind to G35 owners and in addition this APS engine tune will accommodate most basic mods that we'd expect to see on the VQ engine.


I doubt these components will impact of the engine tuning strategy greatly (the fuel octane will have a far greater impact), I'd be far more concerned with lower comp ratio, bigger cams, etc, etc.

It's fair to say that at some point of modification that a custom map/tune will be best to guarantee the optimum level of performance and engine saftey.

Thanks

The engine management is all plug in (no soldering or cutting of wires) so this does simplify the APS single turbo conversion a good deal, here's a link to the plug in computer http://www.airpowersystems.com.au/350z/ecu/ecu.htm

Hope this helps.

Thanks

It does though 94 octane is very common on the east coast of the US, the fuel octane does vary greatly in the US though 91 and 93 octane is the most common unleaded fuel.

The 91 octane tuning map is supplied in the base APS single turbo system though a 93 octane tuning map will be available from select APS dealers.

Peter

 

The only thing that I dislike about APS is as a G owner our kits cost more than the Z kits. Why? because there additional parts? that doesn't make sence the kits should be priced the same.

 

Does GRD offer it?

 

So you can't specify in advance the octane fuel you are going to use (ie 93) and have the Unichip pretuned for you? I plan on installing the system myself with my mechanic during a weekend to save on install costs... but if I can't have it correctly tuned out of the box for 93 octane, what's the use? (since I'll have to bring it to SGP to have them tune it for 93 anyways)

 

I read somehwere (I think on 350zmotoring) that APS has one their tuners coming to the US to work on the 91 and 93 maps. You should be fine by the time the kit comes out.
