hello fellas i have a few IM questions.... the engine is a b16a2

take a look....


-is that line suppost to go to the external map senor ?


what suppose to be bolted down here under the TB?



best regardfs moshik galimidi

 

I don't think that TB is from an Si...

My factory throttlebody had a MAP sensor on top of it. The only ones that I know of that use the external one are the 1st gen JDM B16's.

 

do you have usdm b16 or jdm I have the 2 gen b16 and my map sensor is still the same way. To get by just plug the line on to the m/s it works but i am getting a new tb.

 

FITV

 

the engine is from a civic vti so i think its edm.

 

the top line is just a vac port. you can plug it to your map if you want. for the bottom of the throttle body, just make a plate for it and seal it or bolt a fast idle valve under there and make sure to run the coolant line to the intake manifold or side of the head.

 

that is an obd1 throttle body. The top line goes to the evap canister and the bottom port is for the FITV, as was already mentioned above.

 

thanx.... so where is the map nipple? i can seem to find the sensor on the IM.

you know what, I think that is an OBD0 throttle body now that I look at it. Do you know anything about the car that motor came from? Looks like it has an obd2 wiring harness. . .

What car are you putting it in?
most obd1 and all obd2 (i believe) map sensors recieve vaccuum directly from the IM, whereas the older style are remote mounted and recieve vaccuum like shown here:



maybe if you measure the opening of the throttle body we can figure out what car it came from.

 

i know that the engine came off a civic vti.

but i dont know the year.... is it 1994?




this engine is gonna replace my D14A4 that i dont know if its obd1 or obd2..the ecu is a "P3Y" so im gonna replace the whole harness.. to which obd that engine is.

the car is a 1997 EJ9.


p.s.
are obd0 and obd1 sensor connectors looks the same?

 

yea, that head is a 94.

obd0 connectors are a milky, opaque white color. obd1/2 are a grey or black color.

 

that looks like an sir2 to me

does the Im say p30? I know my p30 has an ext map as well. obd0's said pgmfi on them, the obd1s had the line on the top of the IM and the obd2's were blank.. correct me if im wrong.

my obd1 sir2 motor had a throttle body map sensor.

 

well mine is a 92 maybe early obd1's had ext map sensors?

 

-so which nipple on this IM is for map sensor?

-are you guys sure that its a fitv under the TB?

can i use a D-serise FITV?

 

Not sure aboue edm stuff, but it looks like you have a first gen TB on a 2nd gen engine and manifold. You should measure it, 1st gen TB's are 58mm, instead of 60mm.

why??

the TB is 62mm. (masured from the inside)

and i noticed that it has a port for the map sensor.... :sillyme:

 

^^^ no its not! Only the ITR comes with the 62mm TB, and its a OBDII style with map sensor mounted on top.

You need to measure from the backside (butterfly side).
