Hello, My current set up is a H23A VTEC 1994 Prelude with a DRAG turbo kit, Tial wastegate,MSD 6BTM ignition, Magnecore wires, NGK 3330's spark plugs with .028 gap, Blaster SS coil,Prodrive oil pump gear, Eagle rods, JE 9:1 pistons, Ferrea valves, retainers, springs,valve stem seals, guides, keepers, 3 angle valve job, The block is sleeved and I kept the stock bore, ARP headstuds, ARP main studs, ARP rod bolts, Clutchmasters Stage 3 clutch, JDM H22A LSD tranny, JDM 345cc injectors, JDM P13 ECU, Missing link Map sensor bypass, FMU, Turbosmart dual stage boost controller, Forbidden motorsports shifter, Tanabe racing medallion exhaust. I am running 10lbs on this set up currently. Is this too high?

My questions are:

1. what is the max size injector you can use with the VAFC?
2. with proper tuning with a wideband would this help me run less boost and have more power?

It just seems that in the higher rpms the car kinda bogs? Too much fuel?

Please help if you can. Thanks.

The biggest size injectors you can use I belive is 580cc. I am currently running 580cc with the vafc. The bad thing about using the anything bigger than 450's is the part throttle hesiataion is really bad.

cool thanks for the reply. as of right now the VAFC hack and some 450's seem just in my price range. Later on I will add the AEM ems and wideband. Thanks.
