We have got a Vortech kit on its way to us. We have had great experience with the Vortech products in the past. From its quality parts to customer service from Steve and the crew. We will be looking forward to this kit. We already have a Greddt TT kit that's almost done. So I'll be looking forward to the comparison. From a fiancial stand point. This kit is def. better in price and the installation will also be cheaper.
Looking forward to the install. Here is a link to the Vortech install that's posted by Steve.

Jeff:
I would appreciate your perspective on comparing the two regarding the issues you mentioned above and I am sure others would be interested as well.
I think most mature readers understand that each kit will have its pros and cons and depending on cost, reliability, and targeted hp, the kit a person might select will be dependant on which of these issues are more important.

Hopefully no one will decide which FI system/kit to get based on only one source. I feel the more people do research and listen to installers, experienced modders, and review magazine testing and comparisions, the combination of all that data will make it clearer on which FI kit meets a persons individual goals for their car.
Jeff, you have a valid point, companies like Greddy and Vortech have been around a long time thus it is easy to do a little research on various forums to see how they are seen by consumers that have purchased their products in the past. Newer companies pose a greater risk in if they will be around 3 years from now and how well do they back their product????

The timing controller is not adjustable. It has a map of points based on rpm and boost. We will have a tuner kit available. I will get the part numbers and pricing up shortly.

It's going to be interesting to see how much the tuning kit will cost because if you buy the splitsecond box separately, it comes with the R4 software.
Also, since the splitsecond box comes preprogrammed by Vortech with some timing retard, it seems to me that even 11:1 is lower than needed.
The R4 software allows you to control timing retard, so since my installer had to do custom tuning anyway (the "stock" 350z settings as set by Vortech definitely won't work with the G35) I had my tuner started with 2 degrees of retard at something like 3000 rpm, increasing to 6 degrees at 6000 rpms. With that amount of retard, it is my opinion and the opinion of many I've talked to that 12:1 is safe.
I'd love to hear the official Vortech answer, however.

The short answer is 11.5 air/fuel ratio would be fine throughout the RPM range.
The A/F gets very rich at ~5500-6000 RPM partly because that is where the MAF maxes out. After this point, it starts to lean out to ~11.5 A/F at redline. The A/F up to ~5500 RPM can be adjusted with the split second box, above that you are relying on the FMU, so the only way to lean it out is to lower the fuel pressure which may make it go lean at redline.
Modifications to the engine increase the likelyhood that the Vortech supplied calibration will not be ideal.

Yes, that is my belief. Steve@Vortech has confirmed that the G35 kit will have different programming so I think that's it.

How hard is it to take off the air filter for cleaning??????
