Ok so I will problem look at getting that kit soon with the .81 a/r. How big of a difference will it be spooling wise compared to the .68 and also any idea at about what rpm the .81 will spool at?

So when I find out about the fuel pump and other lines etc. we can go from there then? Or based on what I told you any idea what I might start looking at purchasing?

Just a guess: the .68 a/r will spool at about 3800 rpm, and the .81 a/r will spool at about 4100 rpm. Ask Sound Performance to verify this prior to the purchase.

Step 1 we need to get your fuel system right. Please remove the spare tank cover and post photo(s). One step at a time - we'll do it all properly and plan a rock-solid upgrade path for you.

Are you going to install your AEM, or sell it and go with a simple 'piggyback' fuel controller? If you're going to sell the AEM, you can start this step in parallel. Again, here's a link to a good fuel controller that will get you to 650rwhp (6spd) no problem:

I just placed the order for the turbo kit from sound performance for the 67mm turbo kit with the .81 ar and a quick spool valve to match.

I also took a look and had the shop my car is currently at verify but there is no secondary fuel pump just the fuel injectors and fuel rail. So should I go on ahead and buy a walbaro 255 fuel pump?

So then will my AEM Fuel Management not be enough and I will have to either go with the Apexi or full standalone?

Please do not buy a fuel pump. Again, you need a complete fuel system, so please do not peace-meal it together one component at a time. You'll need lots of fittings, electronics, mounting bracket, regulator(?), hoses, etc., etc. I need to know a lot more before we can decide what to do. Could you post some pictures of your engine bay? Also, could you post some pictures of exactly how your current fuel rail is plumbed?

Honestly the easiest thing to do would be to get an entire fuel system from Sound Performance, and then ask them if they can delete the fuel rail and injectors for a reduced price. This still isn't a perfect solution because we don't know exactly what size & thread fittings go into your fuel rail. Even easier would be for you to remove your current fuel rail and injectors, sell them, and then put in the entire Sound Performance fuel system, front-to-back. However, that's probably not the most cost-effective...so let me know your tolerance for work/rework and cost and we'll figure out exactly what to do.

Please send me information on the AEM "Fuel Management" unit that you have. A link to the AEM website is fine.

I think then what I will probley do is to just buy the fuel system from sound performance just so then I know I am getting everything I need and everything will match up and work in unison without having to second guess. Is the fuel kit from sound performance include everything that I will need?

Ok sweet so I will purchase the fuel system tomorrow and will I need anything else? Like will I need to get camshafts or some kind of new electronic or anything? Yeah I wish I had the full standalone that would be great haha.

Also with the fuel system should I just select getting the 880cc injectors since they are no additional cost?
