Deleted User	the RB ecu should adjust timing for you. if not just adjust it with a timing light to where you think it will be best.

Find a early 90s Z32 ECU and throw it in there, you will notice a huge difference is the car and the you can chip the Z32 ECU which will save you money on a AEM, granted you won't have all the cool AEM features but it's still a tunable ECU

How can I get there? Looking at the stock specs of the RB25, I don't think I would need to upgrade the fuel system (given 370cc injectors). I know the turbo needs to be upgraded as well as some sort of ecu. Therefore, are there any turbos that are direct fit replacement for the RB25? What about ecu choices? I was going to use a Vipec drop in ecu, but at $1500, it is out of the budget. Anyone here do a maf to map conversion as well? Thanks, Jeremy buy boost gauge...buy better turbo...turn up boost...walaa...victory
