Injector size

KaliKarver · 05-19-2009, 03:28 AM

I'm going in for a tune in the next few weeks and I'm figuring my stock injectors (560's) will not cut it. What size should I run? Should I just modify the stockers or get new? Can stock be sufficiant? I've been told anything over 90% IDC is not optimal.

Car: '06 WRX. Mods: blouch 18G, perrin tmic & inlet hose, spt intake, titek catless d/p, tgv deletes, grimmspeed pnp exhaust manifold w/high-flow cross pipe, greddy evo2, hallman pro rx mbc, cobb ap v.1, walbro 255lph.

Car was originally road tuned with stock injectors minus the tgv's, catless d/p, and exhaust mani/cross pipe.

Also was wondering if anyone has any experience with pnp'd intake manifolds and if its worth the money. My main goal is to get the car to spool as fast as possible, not necessarily peak hp numbers.

Thanks

Talk to your tuner. Do what they recommend.

Hey let me know how tune went. Nice modlist

almost the same parts i have (still not installed). I have bought DW 650cc injectors. My tuner said they will be suficient for 18G.

I've got DW 750cc so I have some head room just in case later on. They're only like $30 more than the 650's.

There are alot of factors that go into choosing an injector like altitude, fuel you want to use, boost you want to push and with what turbo so it is best like said earlier ask the person who will tune your car.
