Okay I read reread and read once again the post on the Disco Potato...

Question I have is relating to the size injectors, MAF, etc needed for the Disco Potato...

I plan on bolting on a GTIR manifold onto a SR20DE with S4's and UR 4 Pulley set. I'm leaning towards the O2 Induction manifold.
Fuel needs will be satified by an Aeromotive fuel rail and FPR. Also a Walboro 255LPH fuel pump. I want to know what injectors, MAF would be needed to get around 220-250 whp?

IF I get JWT's 4 bar program then I should get 370cc's? Yes/No?
What about the MAF? Is the stock one okay or should a get a 300ZX/I30 MAF?

Of course all the other necessary components wil be added but aren't relevent.

If you are set on running a fuel rail, then you aren't gonna run 370s; plus, they will top out at the power level you want. If you already have a FPR, then just go with the 50lb injectors, 4-bar program, and a Z MAF. stock MAF won't cut it. You'll end up turning up the boost anyways, no matter what you say now :)

You can make 280 whp with 370's @ 4 bar, 2 mm overbore stock maf and JWT programming for it all. See Andreas Miko.

Running 4 bar and 370's @ 12 psi on a .54 trim T3/TO4e and still pig rich.

Well I'm not bent on running an new fuel rail or anything, but I like to be on the safe side and replace neccessary fuel components. I wasn't sure you could run a FPR on the stock rail, so I assumed I'd need a new rail. I know you need a FPR when running a 4 bar program with the 370CC injectors. I also know you need 50lb injectors when running the 3 bar program. I'm not sure which route to go because I hear for HP around what I want, you can go either route.

I don't plan on going over 250 HP, if I do then it will be in another car because this is my daily driver, I dont have another car, so this has to be drivable in all conditions it would be san-turbo.

Ecu: 4 bar 370CC/3 bar 50lb?
Rail: stock/Aero?

You have to get a reprogram anyways, so that cost can be ignored. Since you already own a FPR and rail, there's no reason not to go ahead and do the 4 bar 50lb program. Injector cost is comparable, and it doesn't cost you any more to go from 3 to 4 bar fuel, so it will be nice to know the headroom is there in the fuel system. It will go nicely with a Z MAF. If you get a bored DE MAF, you will be at its upper limits with your initial power goals. I strongly recommend you build some headroom in your system - you will be glad you did in the future.

Thats cool, I havent bought anything yet... only thing i have is the fuel pump that I bought when I was gonna turbo my Integra.

I have the cams on the way, otherwise I'm still in the decision process... my next purchase will be either an exhaust of UR pulleys, then I will start with the turbo components...


So being that I dont have any fuel stuff, should I still go and purchase a rail, fpr, and the z maf?
