i own an 86 toy pu carbed im swaping to efi will the carbed fuel lines work or do i need efi fuel lines

cutboggers

You'll need the efi line so that it can screw into a fuelfilter right there on your block. + u need the EFI tank for the high pressure pump

thanks for the info but will i need to change my head as well or can i use the carbed head maybe a cam swap or can i use the old one

head should work

myyota

The head and cam will work, you just need everything else to make it all work.

mudtoy1986

sweet well i think i have all i need
intake exaust entire harness tank and pump
all that is left i guess is the acelorator cable and fuel line wich ill get from toyota the fuel line that is if they cost the same as the one for my 90 its about 60 bucks i work in a salvage yard so parts are pretty easy for me to get i scored all the efi stuff for free

Really? So, there's provision for the intake manifold and the EGR?

mudtoy1986

provision? whats that mean ? well the egr was seperate from the intake

thook

Means something provided....as in, the design of the head provides for EFI lower intake and EGR components to be attached to the head....like openings/ports and studs or bolts, etc. So, there is provision or provisions for them.

cutboggers

Well actually the carb and efi cam specs are different however
I would not think that you nor me could tell the difference between
them.

No they aren't, they're the same exact part#. I have the original toyota micro-fiche slides.

cutboggers

hmmm maybe just good aftermarket ones are different.

Knock Sensor!!!!!! 22r does not have a place for a knock sensor and you need it

cutboggers

not to get too off topic but what exactly does the knock sensor do?

jsn_stockard

In a nutshell, it kinda works like a vac advance. It adjust the timing to keep you from trashing the engine. My friend bought a 93 4x4 that had a 22r in it that they put efi on. When he would hit 2grand the check engine light would come on and it would loose power. It threw knock sensor code and engine was dead in two months. I wouldnt do it.

cutboggers

lol yeah not good. So could the knock sensor be the prob with some of these efi 4 bangers running kinda doggish on the bottom end? like below 3k rpm

jsn_stockard

Usually not. Usually you start off fine then get a sudden power drop anywhere from 1500 to 2000 rpm and a check engine light. It usually does it every time you dirve it. The power drop in my friends truck was very noticable, like he lost 5o horses.

cutboggers

lost 50 horses? damn. musta been down to nothin

TOYOTA 1

haha, ya that would put me at negative 25hp
