hello everyone, I am a new member here, and as you may be able to tell, i am the owner of a Honda Prelude. Please, don't diss on me, I'm not here to start trouble and be your ordinary "ricer." I have a friend with a '87 S4 Turbo II and he just recently bought the Apexi EBC. I pretty much joined this site, so I can learn more about the rotary and aspects that go along with it, so that I'll be able to help him with his car, because he doesn't have access to the internet, and he's basically right alongside me in terms of rotary knowledge. So I will now proceed with the questions, any help would be greatly appreciated.

First, are there any write-ups (how-to's) on this site(or any other site for that matter) pertaining to the installment of the AVC-R? He bought it but has no clue how to install it, so a link, or anything would be great. Concerning the wiring especially.

The next objects, I just need to know the location of them, as well as at what stages you'd need to modify, or change them. The Fuel Pressure Regulator, the Boost Pressure solenoid valve and the actuator. Any and AS MUCH info from you gurus would be kick ***.

And lastly, could anybody post a Vacuum diagram and an Engine diagram for me?

Sorry to sound like such a newbie, but hey I'm just an "exhaust leak" so I've got a lot to learn. I pickup quick though. Hopefully we can all get along here on this great website. Thanks in advance.

well, welcome aboard honda guy, have u looked into the engine management section and have u tried using "search"?

1SxyRXy

here is a link that will tell you everything you need to know http://www.fc3s.org/how_tos/electrical/avc.html
you are going to have to reroute the the hose for the stock boost controler back to its self or plug the 2 hard lines off. you will probley know what im talking about when you get to it

Well I tried searching for install write-ups and what not for the boost controller, but I will admit, I was a little lazy on the rest. I posted here because of the higher traffic in this forum, plus not all of my post is related to engine management. If a moderator sees fit to move the thread, by all means do so.

SxyRXy, thank you very much.

EDIT: couple more questions. That write-up is a little vague concerning a few aspects. I assume you have to run the two wires in the engine bay (there are positively only 2 wires that run to the engine?) through the firewall to the actual module or how would that work? Also, does the new boost pressure sensor that comes with the kit replace the boost pressure solenoid valve? This is why I need an engine diagram because I have no idea where some of these components are.

1SxyRXy

no problem. if you got any questions just ask me cuz i just installed mine not to long ago. i will show you a pictures of you is very important that they dont say to do

1SxyRXy

as you can see my solinoid on the left as for the other one you cannot see but they both go in the enginebay wherever you want


you have to uplug the big end hose from the TID and plug it off and after you have that done you plug off the stock boost controler solinoid hole

i dont like honda, but preludes are an ecception for me. anywho, look at the FAQ for FC's sticky. there you will find links to the FSM (factory shop manual). you either will find hords of wonderful information on what you need. or you will find one of those wonderful little "you are not allowed to view this page" things. its a gamble, but its also a very helpfull site.

BTW. ditch the honda and get a real car. i hear mazda has a good car. i think its called rx-7 er somethin.

1SxyRXy

the boost pressure sensor does not replace the stock sensor you just plug the one that came with the kit into the intake manifold. there is a little capped off nipple that you can plug it into its a little barried and hard to find but its on the left side of the engine facing the front of car

1SxyRXy

as you can see in this picture. 1 hose gose to the TID whitch is the turbo inlet duct which is pretty much the intake there are 2 lines plugged into it 1 for the crank case and 1 for stock boost pressure sensor you pull the one that goes to that off and plug it and as you can see on the turbo there are 3 holes on it. you plug one of the AVCR hoses to the turbo and the other to waste gate then you will have one open hose which goes to the stock boost pressure sensor you simply plug that off. in my pictures i just looped it back to itself because i had no plugs.


do you get it or did i just confuse the hell out of you





stock boost pressure sensor thats what it looks like you have to leave it there or you will get a check engine light


stock turbo well an S5 dont think its differnt but the top
right is where NO goes off the apex solinoid and COM goes to on the left side on the waste gate. you then will have a useless metal line on your turbo which you can leave or take off but that middle like goes the stock boost sensor which you just plug off

No one will "diss" you for driving a particular car in here. I mean where really laid back as well as help everyone that owns an Rx7 a **** load, so no worries.
The FSM is the most usefull tool we have in here as well as the search button on the top right hand corner. Just type in what you need to know and as long as you enter the right topic youll find what you need in no time.

Well, I partially understand what you're showing me. I wish those pics had arrows, but beggars can't be choosers I guess. All the blue wires under the hood I assume are AVC-R wires? And the 2nd to last pic you posted (the blurry one), those two red wires are the ones you're referring to? (The crankcase wire and the boost pressure sensor wire?) They're both located on the battery side or is it the air filter side? I'm assuming the air filter side because that's where the turbo inlet duct is right? Sorry, I know that all sounded stupid...

So there are two things that you have to plug. 1) The wire to the boost pressure sensor (stock) and the wire that comes with the AVC-R that's supposed to go to the Boost pressure sensor? I guess that makes sense if that's the case. And after all this, what do you do with the rest of the wiring that needs to be connected to the module that mounts on the dash? Run it through the firewall somewhere?

Also, just for clarification, the boost pressure solenoid valve is the same thing as the stock boost controller solenoid? Just two different names I take it.

Okay, after reading back over what I just typed, I realize, I am confused as hell, did any of my questions make sense to you?

rotoboy20, thanks for the tip but for right now, I'm content with my Prelude. One day, I want to get a rotary though no doubt.

RylAssassin, thanks for the greeting.

i should really use arrows i guess but anyways. the 2 red wires have nothing to do with the stock sensor. i actually took a picture of the blue hose. the bent blue hose are 2 metal lines that go 2 the stock sensor. you the one you can see but the other you cant which goes a little farther back behind the water pump.

Preyluder

So you just looped the blue wire (which was on the car stock?) to itself pretty much? I still don't understand what you do with the wire that goes to the crankcase sensor, which is underneath the boost sensor wiring. I do understand now that you're supposed to plug EVERYTHING off that is related to the STOCK boost sensor, correct? Once again though, what do you do after all this? That's where the write-up was quite vague.

I feel as though I'm pushing the limits here. Don't wanna **** you off, so if you don't feel like answering my 230,000 questions you don't have to. i do have to say though I'm extremely thankful for all the help you've given me thus far.

1SxyRXy

ok bare with me here for a little bit i will make a totally detailed walk through just hold on for a bit

1SxyRXy

this pictures basicly shows that its new pressure sensor that comes with the kit. the hose that comes off the bottom goes to the intake manifold

the line that comes off the pressure sensor ends up here at the intake manifold











tell me what you think

Preyluder

Well, all I can say is WOW! You went above and beyond man. Thanks for everything, I'm definitely grateful.

i guess we can figure out what to do with the rest of the wiring. I'm assuming all we have to do is run it through the car via firewall, under the dash and into the module box?

1SxyRXy

run it wherever you please just gotta drill a fat hole in the fire wall for the wires and be sure to put some reflective crome tape on the wires to keep some heat off them if they are close the exhaust like my car. here is where i mounted mine

i can still put my lid on it too
