hi everyone, as i said last time, i'm goin to boost it up my corolla, and i already have a Td04hl-13g turbo whith wastegate and blow off incorporated, and i think that i can use the JDM EP91 Starlet Glanza V inyectors (or starletGT inyectors), im goin to use an AFC controller, and finally a intercooler (i dont know what size i have to choose for have less lag for this turbo).
Ok, now i'm thinking, do i have to change the MAP sensor?, i need one from a turbed engine?
i have stock internals cos i dont find low compression pistons for the 4a-fe (i really think that theres no pistons for that engine) and im goin to use 8psi of boost, or my engine can handle more boost?
ohh there is something else, my rear brakes are drums, and i whant to upgrade them, i dont know if the usdm corollas have the rear brakes whith same fitings as mine (jdm/ukdm), or from what toyota do i can use the rear drums?
really, the afc and bigger inyectors are not good? what do i need, remember that i'm goin to use low boost
your stock computer management system won't be able to compensate for the change in a/f efficiently. it will always be fighting with each other. it doesn't matter if your running low boost or high boost. its the tune thats most important. with a good tune you can run 10+ boost problem free. and also with bigger injectors your gonna need a bigger fuel pump

thanx for your advise, what fuel management system do you recomend?
How much you spendin on dat man i got my 07 corolla N/a with nearly 230 h/p and 210 to the wheel
you have a 1zzfe w/ an auto and IHE and you have 230 whp...?
anyway, id imagine a decent piggyback would suffice, i dont see why for a low boost setup like hes talking about a SAFC and injectors should give him a decent tune...?
and also with bigger injectors your gonna need a bigger fuel pump
Not necessarily, alot of EFI pumps are capable of quite alot of flow, you're going to lose pressure if the pump gets too small.
Max flow comes with zero pressure and pressure is made by restricting flow.
As for management, piggyback suck, they work by cheating the existing ecu of sensor information. You WONT be able to use that reliably if you want to have decent boost. Fueling and timing tables go hand in hand, so you're going to be having a difficult time with them.
Standalone systems range from the very cheap megasquirt to expensive full systems.
Van Kronenburg managment systems (KMS) offers a standalone for around 700bucks.

well there you go, flash answered what i was about to say but with more info. and the general concept about the fuel pump you correct but he has an ae111 which i'm sure he will need a bigger fuel pump since he is going with larger injectors and the stock one would be as good. i suppose it'll depend on how much fuel and how much power he is making
to add, other standalone that exists are hydra, aem, apexi etc. they are the most costly but also the best gains when compared to piggybacks and the a/f controllers
For engine management you can use the 4efte map sensor from the turbo starlets with your ecu and some injectors about twice the size of the stock ones, its an old trick that will work really well. Also look into a msd btm for timing control under boost. a vafc is the same as a afc or safc, only difference is that the vafc has the settings to control vtec. A vafc can be used on a toyota with some bigger injectors and give good results. your rear drums should be fine, no need to upgrade if nothing is wrong with it imho. Upgrade the front brake lines, and brake pads, i am willing to bet that you can lock your wheels if you stomp the brakes . If you wanna minimize stopping distance i say get some really good tires and work from there. Your intercooler has nothing to do with lag. Ebay has nice fmic for under $100 .
