Please tell me, if there is any way to put a b18a or a d16z6 TB on a MPFI 90 si manifold. I cannot find a new throttle body, but I have alot of other engines at my house that I can take one off of Or even a d15b vtec TB? please help

 

You can use the z6 tb.

 

really???? you are my hero!! ok so do I have to take anything off of it or put anything on to it?

bump again...I really need this quick..thanx

 

you can use damn near any honda throttle body-D-H-B-----but keep in mind the location of the IACV on each one, some are different. but they will all work.

 

obd1 and up throttle bodies have the map sensor on the tb
obd0 have the map on the firewall

 

i got one for a 91 rex si 25 shiped

Honda has two main flanges for their Throttle bodys for the pertinent motors(D, H, B)
1) The first flange was for the 88-91 MPFI D-Series, this was used for a bit....and then dropped off the face of the world.
2) The second flange sprang to life with the introduction of the B-Series in 1990 and in 92 spread to the D-Series and whenever the H-Series popped up, it spread to that too.

 

so the FAQ at the top of the page is wrong also?

hmmmm.... for missinformation being flung around.

 

Why do I get more and more confused as paople leave comments?? Mr Latino, I am not understanding what you are saying. Will the d16z6 throttle body fit and work on my 88-91 si mpfi manifold?

Let me break it down further:

[B[THE ONLY[/B] Commonly found throttle bodies that will work on the 88-91 SOHC MPFI intake manifolds are the throttle bodies designed for those manifolds.

 

then how come i used to have a LS throttle body on my manifold, and a z6 throttle body on it now

 

B16A and B18A throttle bodies will bolt onto the manifold. You need to bore out the flange on the intake manifold itself so the B series throttle body can open up 100% with no interference.

 

what about the d16z6 throttle body?

 

I don't know if it will work. I know the whole IM bolts up, but theres no point to that.

If I were you I'd look for an LS throttle body and port match. If you are going to cam the A6 it will be useful, if you are going to turbo it will be useful aswell. It's useful all around without a tune.

 

dood why dont u just unbolt the damn nuts and try to put it on....???its more work asking everyone then just trying urself. if it fits it will work, u might have to bore out the hole a bit tho. i know on 92-95 d series that integra throttle bodies will fit cause i have a gsr TB on my z6 intake mani.
