11 turbo questions 95 accord
okay so let me get this straight i've been reading up some. okay so the turbo has 2 wheel one on the cold side aka compressor side for the chargepipe and one for the hot side exhaust side..
well if i'm correct the turbo has 1 shaft but 2 turbine wheel.. one a exhaust turbine wheel and a compressor wheel.. so when you 1st start the car up the 1st combustion that is made.. it goes thru the exhaust side.. thus spinning the exhaust turbine.. thus spinning the compressor wheel since its a shaft connected to both wheel.. than the turbo will begin to spool up... then the cold side of the turbo gets connected to a chargepipe.. the charge pipe than goes on one end of the IC.. ic cools it down for a few second than exit it thru another end of the IC with another chargepipe that takes place of the intake system that gets connected to the IM. #1. is this correct?
okay # 2. i heard that the bov is usually a flange welded on the chargepipe and u just bolt the bov to it.. wel my problem is that most kit doesn't come with a flange welded on the chargepipe.. so what do i do now..
okay#3. i know the bov is to relieve pressure when you switch gears so that it doesn't countine to build up pressure in the chargepiping from the turbo since your letting off the gas but what lets say if u didn't install a chargepiping.. wouldn't the air than escape back to the cold side of the turbine compressor.. spinning it backward.. thus spinning the exhaust turbine wheel and just exiting out the exhaust dumptube or manifold?
okay #4 the wastegate has 2 flange one gets bolted to the turbo manifold.. the other end.. i heard goes to a dumptube.. i'm assuming this is so when you've say you've build up(lets say 10lbs of boost) the turbine wheel won't just automatically stop spinning because you reach the amount of boost you want so does the wastegate open up and instead of spinning the turbine wheel on the hotside faster to create more boost.. it slows down because the wastegate opens up as a secondary exhaust to let out some air.. but if what i said is correct than what if u hold the throttle constantly and it spool up 10lbs.. even though the wastegate opened up.. since the turbine wheel isn't going to stop spinning won't it just make 10lbs of boost plus a lil more since the turbine wheel is going at a lil rate.. thus risking blowing your motor.?
#5. what does trim a/r .63 or .60.
#6. okay i know that the turbo get connected to a manifold or rather a header that goes to the block.. than the wastegate than the downpipe right
??
#7. okay i wanna boost my 95 honda accord ex.. for all these lil civics with gsr swaps and ls swap.. or even accord with h22, si. thats been talking ---- i want to serve all of them this spring hopefully. but do you think a f22b1 thats vtec will be able to do 10lbs of turbo and will that get me in the 220whp or 240whp range?
#8 for tuning i've been thinkin about getting a obd1 p28 civic ecu.. only problem is i can get one for free at a junkyard. is it cheap to get it sent in for chipping.. i mean i know i can find one chipped online for around 200.00 but will it cost that much if i can get one free and just get a chip put in?
#9 if i buy a used p28 already chipped i'm assuming its going ot already come with the owner basemap.. will they reprogram it or atleast delete it and use a new basemap for me can they do this?
#10 detonation is when the cylinder goes to fire.. the air gets so hot that the fuel ignites it before the spark does? casuing misfires? if misfire happens how does that make you throw a rod.. i could understand you'll get carbon build up or atleast you would be running rich right? because of the unbunrt fuel or no
#11. i plan on going with 450 cc injectors... colder spark plugs chipped p28 a nice basemap setup
I WISH YOU CAN ANSWER ALL 11 OF THESES QUESTION THOUGHTFULLY AND ALSO IF YOU GOT SUGGESTIONS or comments please free feel to post it.. PLEASE KEEP THIS THREAD FLAME FREE.. ALTHOUGH THIS IS MY 2ND DAY READING UP ABOUT TURBO...

Re: 11 turbo questions 95 accord
you seem to be grasping the concept pretty well.... 
#2 weld a falnge on or geta flange welded on.
#3 The bov prevents the turbo from spining backwards... it is verry bad for it to do so... so yes it lets out the presure when the throtle boddy is closed
#4 the waste gate dose what you said... lets out exaust so there is less of it to spin the turbo.... you can set it to any psi you want with the right spring and boost contorler.
and im done with help for now.. ill give som emore usles infor later. if its not covered by some one else

Re: 11 turbo questions 95 accord
Your f22b1 is a good motor for your power goals, you can definately reach those numbers without needing to upgrade the internals. The junkyard P28 will work great, you should be able to find someone to chip it for cheap and it'll save you alot of cash over buying one online. You can find answers to all your noob questions by doing some more research
