b16t4turbo

i have a b16 bulit for turbo and its not running right. here's my set up.
block- dymanic sleeves, stock bore (81mm) je pistons with 9 to 1 compression on eagle rods.

head- stock type r with 1mm over-sized stanless steel all motor vavles to raise the compression .5, crower dual valvesprings and retainers, jg intake manifold, ctr intake and exhaust cams, skunk 2 sprockets, msd spark plug wires, ngk zfr7f-11 spark plugs, msd 6al with ss blaster, type r thottle body, missing link, str fuel rail, vortec fuel pressure regulator, rc 440 injectors.

turbo set up-custom turbonetics t4 ceramic ball bearing turbo, drag manifold, hks wastegauge, hks sequenchal blowoff valve, spearco front mount intercooler, greddy profecb boost controller, greddy turbo timer.

other electronics-apexi vfac, air/fuel ratio gauge.

well here's the problem, my turbo doesn't start to spool till like 6,000 rpm but the the car bogs down at about 5,000. i tried to play with the apexi and the most i got it to boost was 8 psi with the boost controller maxed out. i tried to switch to my friends 370cc injectors and they still bog down between 5-6000 rpm. i tried to use my 310cc injectors and it let me boost higher but it leans out. someone told me that it bog because of the injector so i tried all those other ones. i don't know what to do next, so any advice is very appreciated. thank you.

Are you running ANY sort of engine mangement besides the missing link?

b16t4turbo

no just the apexi vtec controller. i do have a hondata s200 with boost option but i was going to see if i could do it threw the vtec controller. do you have any ideas y it would bog like that?

Hmmm, if I had both of those, I'd stick the Hondata unit in there.

As far as the bogging issue, JDavis could probably help out...he's got a thread going somewhere in here about the afc hack recurve...maybe that can give you some insight.

b16t4turbo

there isnt a reliable dyno tech to tune here in fresno so i wanted to see if i could do this with the apexi. who is that and how do i ask him?

sounds like you have everything you need but you did not mention a fuel pump. what fuel pump are you runing?

Stewie

well, if you don't have the hondata installed, using a missing link with the afc is like running stock fuel trim. If you want to use the afc, you have to remove the missing link and intall 440cc injectors. From there, you have to trim down the fuel using the afc.

mod5

check your fuel pressure regulator... what is it set at?

thats the thing too, with the vortec fpr when i set it at like 55 or higher the motor starts to shake like its about to die down, but when i lower the pressure to like 30 the motor idol at like 800 rpm. is that right? what pressure do you think i should put it at?

can you explain this more please on how to trim the fuel and so forth. thank you.

mod5

is your vortec fpr 1:1?

you might want to check if your injectors are seated correctly? or you might have a crimped rubber injector o-ring.

b16t4turbo

yes it is and i just checked the injectors and it fine, no crimps what so ever. i all out of ideas. all i want is to see it run right but i might have to just take it to dyno, not unless anyone else have any other ideas. please help!

sporkcrx

put in the hondata and putt the car to a dyno. it'd be worth the drive

Without a FMU you're not getting proper fuel. You can't run a missing link and an AFC without the FMU. You can try the AFC Hack if you have 440cc injectors. Look up info on Hack settings. I have it on my car and it's great to 10psi.

b16t4turbo

at this point i will try anything. well let me try this and ill see what it does. you did say take off the ML and leave the FMU and just hack the VAFC right? thanks.
