I unbolted my d16a6 throttle body and tried to put it on my y8 manifold does not match up so which one do I need to get to flow the best and be easiest install.....second other then extending the wires on the map sensor any other like modifications I need to do?

 

You can bolt any b series and h series throttle body on the y8. I am puttin an h22a4 on mine. The s2k throttle body will work as well. I know there is a pic someone put on here recently of almost EVERYTHING you would need to know on installing that manifold. Try a search and you will find it.

f series work to, with alittle modifcation, but i thought ur a6 tb should work?

 

Integra TB's are a good choice. I'm running a GSR TB (60mm). You will need to port the manifold though if you want to run somthing bigger than the stock Y8 TB.

 

i've got a 1st gen b16a throttle body on my y8 with no modifications

ive got a B18A1 (58mm) TB on mine. i also have an extra one for sale if your interested. it includes the TB with TPS and dashpot, IAT plug with 6" of wire, 86-87 Si d15a3 throttle cable bracket, and an extra d-series throttle cable disk (puts cable at a better angle than the b18 one).

there are some instructions in this thread https://honda-tech.com/zerothread?id=573612

but heres my preschool pic and instructions:

sorry for the shitty pic...my wonderful scanner turns everything into garbage.

this is a 96-98 d16y8 intake manifold with a 90-91 b18a1 throttlebody, a 99-00 civic si intake in a 88-91 civic/crx. IAT wires have to be extended around a foot or so...IACV wires might have to be extended a few inches also, check to make sure first. TPS plugs right in...stock MAP is used. can use stock obd0 IAT, but have to mount somewhere in intake...or rubber boot for aftermarket intake if you dont like cutting nonreplaceable things. or obd2 IAT can be used with correct plug and will fit in intake as shown. i used a reducer in the line to the dashpot on the TB...cause one plug is big and one is small.

note: i had to use the stock d16a6 throttle cable "crank doohicky thing" instead of the b18a1 disk...because it set the throttle cable at a wierd angle. i also used a 86-87 d15a3 (civic/crx si) throttle cable bracket...cause the upside down d16y8 one didnt fit right for me. also...my y8 manifold didnt come with a IACV so i used one from a 98 f22** accord. if you dont run coolant to it one from a 89 mpfi accord will work if flipped backwards. all injector gaskets are from d16a6, fuel rail is d16y8 and fuel line is d16y8 (but stock will work if aligned right).

the fast idle thermo valve is unplugged from the harness and not used at all on the y8 manifold...it will not throw a CEL.

make sure to check TPS voltage...it will hold idle, i promise.

any reason you chose to use the stock MAP rather than the map on the "new" TB?

the 90-91 B18A1 TB doent have a MAP on it...it uses the same MAP on the firewall setup that the civic/crx uses. just run a vaccum hose from the TB to the MAP. one less set of wires to chop off the harness and lengthen.

 

you can use either one, i've used both different setups with no problems
