here are some links to those items

here is a complete kit includes
AFM/INJ/INJ clips
this will give you most items, after this you just need the adj. fuel pressure regulator and you'll be set.

ADJ. press. reg kit LIPP
1
this allows you to control the amount of fuel entering your fuel rail, it will make it so you are going to be killing your engine with an overflow of fuel and possibly burst your lines. although the walbro pump is very stong and can take alot, i still recommend this adj. pressure kit.

if you really want there is another removal system to get rid of your Fuel pulse thingy, i really dont know what that does but its ugly and not needed. and here a link for that kit to.

fuel pump

there are diffrent types of pumps availible, the walbro is the easyist one though, it will go right into your tank just like the stock one. pushes 300% more than your stock. and will allow you to do your 550cc/+ injector system , now dont order the venom injectors, they have been highly known to stick, and this can make a really big issue. so i repeat DONT ORDER VENOM INJECTORS, RC are the best so far. PTE "precision turbo engine" are the next best. i am running the pte 550 and are sweet so far.

injectors
1 - supra sport
2 - ebay - 1000cc injectors availible from these guys also

these will allow you to use your pump to its full potential, and plus they are almost needed when you upgrade to your Lexus v8 afm, i've heard of people not changing the houseing but just the sensor and running somewhat lean. i dont know this for fact but its just something i have recently heard, DONT ORDER VENOM INJECTORS THEY STICK AND WILL CAUSE MORE PROBLEMS.

AFM
1 - supra sport
2 - these are used and imported from jap. but very low mileage and clean and work.
for injectors with the lexus afm 550cc are good 680cc are better. but i dont see why you cant go bigger maby even a 750cc like i posted

now just to make things even simpler, i will say that i recommend getting a fuel controlling system like the apexi safc "ebay you can find them for like 25$- 100$" all of these items together with forsay the 550cc injectors you should be good up to 450hp-500hp. if it comes down to the point you still are hitting fuel cut then the next item recommended would be getting

1. HKS FCD - fuel cut defender will remove your fuel cut system and if i remember right you should be able to adjust them to were you want your fuel cut to be set. HKS USA Driving Performance - Homepage

2. i should have put this in the list of items because it is very important to watch your Air/fuel ratio when doing anything with your boost and fuel. but recommend any digital system that will use a wideband sensor. not one you tap into your stock 02 sensor. wideband is very accurate warms up faster. and is a real time reading. and very good for tuning may i put.

i personally am running a AEM UEGO w/wideband, and so far its pretty sweet, others recommend or use the Powerdex AFX-Air Fuel RatioMonitor

now your probably thinking to yourself, damn this is alot of money. but in the end its all worth it. you will get some more horsey's and you will be able to boost up to 18psi "not recommended on your stock ct-26" or 17.99psi so i have been told i'm not sure yet since im still in the process of breaking in my motor :P- - -||____XD

hope i helped you all out with your questions. i'm willing to help to what i know so ask again and ill reply back for you
