hey guys,i own a 95 sc400 with a 2jzgte swap auto,,i am in the middle of converting to single turbo(presicion 67) and my power goals would be 600hp...i want to upgrade the fuel system and piggyback system...what do i need to upgrade the fuel system..? i know i will need a walbro fuel pump,upgraded fuel rail,injectors ,regulator is there anything else? and as for as piggy back system...i would need more then a safc..can i use a VPC? i know i am using an aristo ecu but is there anyway i can make a VPC work..i would go standalone but i am on a very tight budget and i know i can purchase a vpc for those who wanting to get rid of them..

vpc is designed to replace AFM with MAP-

Aristo 2jzgte ecu does not have AFM, so VPC is kinda useless.....

so what is the best piggy back i should go with? i figured the vpc will be useless..but i know the safc wont cut it also..would i need to get a mk4 supra ecu? to make the vpc work?

Try looking into AEM's FIC. It's a fuel and ignition controller. You can use an AFC depending on how big you go on your injectors. With an AFC you can only go 50% above the stock size. So for example if you're running 440cc stock you can go up to a 660cc injector and still tune with an AFC. The FIC is a better system because it does more than just fuel it allows you to play with your timing. They are fairly inexpensive somewhere around 400 bucks. Check them out!!

never heard of this AEM fic..i will look into this..would this be better then the AFC?

I think so. It does timing and fuel, where the AFC only does fuel.

you really dont get it do you?

jdm ariso or MK4 ecu > usdm mk4 ecu due to MAP only, no afm.

if you want full piggyback control over fuel and timing, just use Greddy E-manage ultimate with the JDM ecu

or get a real standalone.

why would u want to use a 15 year old HKS VPC anyway?

if you want 600rwhp, get your tuners choice of standalone, install it and tune. then you will be ok.

single or double fuel pump depending on your choice of pressure and pumps.

2x mk4 oem denso or 2x 255 walburrito would seem the popular choices
