i was wondering what would be better for a 10psi boost setup. at first i had decided on going with a walboro in-tank pump, dsm 450 injectors,resistor pack, and the AFC hack. but then some budget issues came up and now i'm thinking it'd be ok to go with a 12:1 FMU, inline pump, and keeping the stock injectors cus it'd be more budget friendly and would still be good for what i plan on running. would i still need an AFC eventhough i'm using an FMU???

the setup:
91 b18A engine
ARP rod bolts
T25 or 14B turbo
DSM IC and BOV
and one of the two fuel setups listed above.

 

I'd go with the 450cc, intank, and afc just because you can have more controll over it.

Me too. Unless you plan on boosting 5 or 6psi max, I say use the hack. Even with an FMU setup you really should use the AFC anyway.

 

Its all about the afc hack. Its about 1000000000 times better. I FINALLY got my turbo hatchback working again (motor problems) and running around town its just sooo smooth. No hesitation..just smooth acceleration...the switch between vacuum and boost (i shouldnt use the term switch because there isnt one) is just not there...super smooth.

i got 450cc's in the mail found em on the parts trader for 100$ shipped 45k on em the guy used FI cleaner every oil change so i can wait to put em in now i need a afc lol

 

Punct-u-ation.

 

450'S, intank, and afc if you have money issues, if not ditch the afc and get hondata or EMS!!

 

inline
450cc
afc hack.

you have all the bases covered

 

Afc hack hands down for your situation.

Question is the stock pump perfectly fine for AFC hack? Cause I wanna take my noisey inline out once I get my 440cc's I'm sick of the noise.....

 

thanx for the input. i was just checking. the inline + fmu setup was just to get boosted in the first place then later i'd upgrade to bigger injectors and either the afc hack or hondata depending on what i wanna do with my car.

 

eric, your stock pump is perfect for the afc hack. your running stock fuel pressures.

 

So if you run a intank, 450s, and afc, you dont need an fmu?

 

Correct. And in a post I made yesterday, asking that exact same ?, I was told that you dont even really need the intank, altought its not gonna hurt anything having it in there. I am keeping mine.

Could you also use and inline and an intank with a vafc? I have some dsm 450'ss and I'm in the process of installing them. I know the fmu will be ditched but will it hurt to run both types of pumps?

Oh yeah...I'm and running inline/stock injectors/fmu right now.
