MODIFICATION , THROTTLE BODY ( 4G Accord / Ford 65mm + B16 Manifold / TB Spacer )

[Accordtheory]

Even if you had identical voltage vs. %throttle opening #'s between the 2 throttle bodies, u would still have uneven voltage vs. aiflow #'s between them., due to the different diameters.. How close is the voltage output from the tps at the same throttle opening? This might affect "acceleration enrichment"? My car has lousy throttle response, and it supposedly because the chip isn't perfect for the TB and manifold. Why would you ever need a bigger TB than the integra one anyway? (i also have the same manifold) I am curious to see how much of a difference increasing the TB size makes on a dyno too.

i fixed the tps problem: i slotted(not adjustable normally) the sensor and moved it a hair clockwise.

I dont see how this t/b would affect the iacv or fast idle valve. On my manifold they both WOULD HAVE run off straight vacuum. Besides, neither are necessary, their more trouble then their worth. Ford t/bs dont have and "idle screw" but it does have an adjustment for the linkage-stop which i didnt have to touch.

As far a vacuum, just tee in somewhere.

if i remember right some of the older fords (late 80's maybe) had adjustable tp sensors. might make things easier.

Did anybody figure out how to fix the weird idle problem?

[1988starter]

Nope I don't think so but I still have the TB 140 + shipping

[Vanilla Sky]

use longer mounting studs

[mykwikcoupe]

actually yes they do just srew in. use a stud extractor like with your head bolts and they come out. Id recommend tapping them for the replacments. I dont like press ins since the ripped mine out of my thunderbird heads

[gfrg88]

what does putting this spacer help in?

[A20A1]

it increases plenum volume

[mouchyn]

and doesn't really do a damn thing to an engine like the A20 unless you're already SERIOUSLY modded.

so what ford throttle body works , im hopefully going to a junker this weekend. does it bolt on or do i have to modify it ... does it fit up to the stock manifold.... if i ge the b16a manifold

[Sporno]

what do i do if i cant weld it , can i just bolt it on or something. with the stuff i do to the car failure is not an option. and if i get a b18 manifold caould i take the injectors and stuff off of my current one and put that stuff on the new manifold?

[Sporno]

ok that makes more sense nw. so when i go to a junkyard ( hopefully this weekend ) i just get the B18A manifold and its fuel rail adn im good to go . how much u think it will cost? at a junker that is

[Sporno]

could i take my stock throttle body for now and use that with the b18a manifold? also any chance it would be under 50? i need to know exactly what to get when i go .
