I am building 2.2LR ported stock head HKS 272's FP Black running on e 85. I know i am going to have to upgrade my fuel system again i am planning to do a buschur racing double pumper and most likely do upgraded custom braided fuel lines and an fittings as for injectors i am unsure. i am planning on pushing this turbo to the limits and want to over build the fuel system so what would be a good size injector i am thinking FIC 1680's.

 

like a lot of people will say change out those HKS cams for some GSC S2 lol

 

yea those hks cams are not to good i heard. i would go with gsc s2 are kelford 272.

 

depends on you who ask i guess.....us supra guys love hks cams?

 

well they suck on Evos

 

I recently put a build together similar to yours

2.2 Cosworth Crank
156mm Carrillo Rods
85.40mm CP Pistons(10:1)
Cosworth M2 Mivec Cams
FP Black too

For fuelling I have a Walbro in tank feeding an inline Bosch 044 and RC Engineering 1000cc injectors. I also on occasion use a 10% Methanol in tank mix and the fuelling is more than adequate

 

To overbuild your fuel system for your needs the 1680s will do. The one thing that is currently kind of a drag is the 1680 is only slightly less than the 2150. Both are marvelous but if you are only looking to spend on what you need the 1680 and dual pumps will get you there.

aaron

 

i am making good power with the HKS..or was i will see how they do with this set-up. i was planning to get FIC 1650's however i may just step up to the 2150's i just dont know if it is going to be harder to tune. also i think i will just stick with the double pumper and custom -8 feed line. also what is a good fuel pressure regulator?

 

from what i hear the 1650 low impedence are a terror to tune. the high impedence 1680 and 2150's are supposed to be great!

 

i may just go with the 2150's in that case

 

swap those cams out!
