D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
hi, we are having problems making boost, gauge is not showing nothing at all ,also the BOV is not going off,
here is my setup: 5G HATCHBACK CX D15B8 ,140,000 miles running strong IHI RHB5 TURBO ,welded to STD MANIFOLD {8 PSI} GREEDY TYPE-S BOV DSM INTERCOOLER QUESTIONS: if i set at 8 psi , should i av the BOV adjusted to hardest or softest or in between ? also who has to be done for me to make boost ? stupid question but i have ALL MY PIPING SET TIGHT, AIR TIGHT, and no exhaust just small down pipe, i HAVENT DROVE Th car just revved it to 6 grand in neutral and the wastegate didn't open, or the BOV, can someone please help me out, and if u do send me your PAYPAL: as i will senD 25$ if u give me good help and explain, thanks TK AUTOMOTIVE |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
Drive the car but make sure the boost guage is hooked up so u can monitor your boost and see if it goes higher then needed. My car wont make boost untill i drive the car. oh and how do you know the wastegate is not stuck open? i would deff. suggest driving it and slowly build boost untill the wastegate opens if you have the engine management for it and is ready for 8 psi dont drive it w/o engine management.

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
oh and as for the BOV you have to set it according to your car/turbo setup i would start soft and tighten it untill you hear compressor surge then back it off a hair. You have to drive it to do this also. Drive, listen, adjust drive, listen, adjust ect...

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
Usually it needs to be under a load, aka driving the car before it starts boosting and for ---- to start happening. Since your only pushing 8psi I would just leave the bov cause your not really pushing a whole lot of air. If you start to hear the bov while building boost then you need to crank it down some more. If nothing then just leave it. Paypal is hndphilemon@tds.net

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
get a dx head and ecu like 100 bux from the junkyard, or find a buddy most people end up throwing a dx head away. (d15b7). the d15b8 and d15b7 are the same motor only difference is the b8 has an 8 valve head and the d15b7 has a 16 valve head. it is a strait forward swap and can be done by a noob in a day. d15b8=70hp d15b7=104hp. its all in the head cheap 30hp bump

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
can a D16A6 head 16 vlalve from a crx si ?
my WASTEGATE is closed and not stuck as i had tested it and it moves, ok so also i hae a 91 civic map sensor with check valves were do i hook up the check valves ? straight to the IM right, and which way should the check valves be set . and last thing so with 8psi should i b ableto hear my type-rs BOV ? and ur saying start off with soft and then tighten till u hear compressionsearge and the back off a bit, now does anybody have a diagram on how to hook up the wastegae and bov and boost controlle a i hard they all hook up together ?? and m turbo has alitte nippole onthe housing should i block that ? and the first person that wrote info to me i think he did a goodjob and answered most of it rigt ? wats yor paypal ? |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
also how long cn a turbiun without any oil ??

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
ok take a vacuum line and run it from your wastegate to your turbo's compressor nipple.
take another vacuum line and run it from your bov to your Fuel Pressure Regulator ( you will have to get a vacuum T and but it in the line that goes from the IM to you FPR and then hook you bov line to that ). The boost controller you should hook up when u get to the point where everything is running and working good at the wastegate setting ( you said was 8 psi ) Then when it is all doing well and your engine is tuned for it then you take the ( assuming manual boost controller) and hook it up between the line the goes from your compressor housing to your wastegate, just cut the line and put in in between and start off with the boost contoller setting all the way down and slowly turn it up untill you reach the desired boost level. As for check valves i dont think you need to put them in unless your running over 10psi but im not 100% sure. if you have everything done correctly and your getting a Check Engine Light when you hit full boost then you need check valves otherwise don't worry about installing them. Oh and if you get the CEL then just turn off the car and re-start it and it should go away untill you hit full boost again. all the the cel will do is put your ecu into limp mode. Yes your BOV should make noise when you let off of the throttle. It might need to be tightened up, just keep tightening untill you hear the noise then when u first hear compressor surge back it off a hair so you dont have any surge. Anyway how did you make out with he first info are you making boost yet?? Also if you are not when driving it then check the charge pipes for leaks because thats 99% of the reason there isnt boost when driving and make sure you didnt blow your vacuum line for the boost guage out i have dont that before and u can tell when you see the guage at zero and the engine is running.

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
i wouldnt run a turbo w/o oil but if you did i would think it would last very long at all maybe a few days im not sure. :-\

FUEL CONTROL/MANAGMENT, i do nt careif this makes all the horsepower and how ong it last i just want t hear it, and run it and feel a slight difference, so my question is do i need fue managment ? or will my fuel setub b ok for a bit , and then chip my cu and run richr and urbo ecu ? |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
Dont run a turbo with no oil, NEVER, even if its just idling.
And don't actually send people money for helping you out, we can do that for free. |

Also i dont run a catch can so i cant help ya there, but the line from your compressor to your wastegate can be long or short ( probably better to be short ) As for management you will at very least need to run an FMU which i would not reccomend. I would get some DSM 450cc injectors and a basemap from xenocron it would cost you maybe $100 if you are able to read and chip it yourself, otherwise send him your ecu for idk i think its like $80 and get some injectors for cheap, check the local junkyard for cars with big injectors and make sure u have your injectors before you get an ecu shipped because he will chip it according to your injector size. |

u name it, we have civc,crx,delsol,intera,nsx,legend any honda/acura tuer part or oem, we also have a local pick-n-pull junkyard soi can get u anything, u name it, i would be happy to send u something to show u im not an ass just using people im a friend that just needs help LOL, but whatwill hapen if u just run it on my cx setup ? at the very least should i get a dx ecu ? im new to the turbo thing, our shop is for high compression buildslike m 94 civic vx that i have D16A6 block and D16Z6 had and hae 14;3:1 CR and hitting 12's, its full out built, andnow we are turboing this civicv cx i had laying around to c wat we ca do to it just for fun LOL
and i have money to jew out for help, and quick honet responses and no BS that i will pay money fr over lots other or like i said send hi a part as we have a ---- load and scrap shells that have parts inthem once we get what we want out of them , so let m know |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
OH and what is LIMP MODE ??? ??? ??? ??? ??? ??? ???
|
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
limp mode is a safe mode that takes power away from your engine i think its more or less safe fuel maps.
|
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
oh and for your ecu, you need more fuel and a dx ecu will not do that, you have a few options.
A FMU is cheap and simple to hook up but not a good choice. It raises fuel pressure at a ratio to boost. For example a 12:1 FMU will raise fuel pressure 12 psi per 1 psi of boost you run. so if you run 8 psi it will raise fuel pressure 96 psi over stock which would be 128psi fuel pressure which will actually push/force more fuel into the engine under boost and you keep your stock injectors but depending on the ratio you go with u will more then likely have to get a better fuel pump. you could get say a supra turbo pump, or mustang pump, or buy a $100 walbro pump made for your car like a stock replacement just capable of alot more fuel. Another option is to get a Apexi SAFC which is also not a very good option and you would need bigger injectors and someone to tune it and it is more expensive then chipping your ecu which is 100 time better. If you want to feel boost for more then one pull i would deff. get some kind of fuel management. Not only will the reliability of your engine depend on this but so will the power that it puts out plus an ecu will take care of the check valves, you would just remove them because your ecu will need to use the map sensor to see boost to change the map accordingly. To sum it up i wouldnt waste my time going through all of the work and time putting a turbo on w/o some decent engine management. |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
oh and i need a stock throttle body for a d series if ya got one laying around nothing special im just tired of my engine not being able to idle properly. ;) yet again you dont have to.

SURE i have about 5-6 D series throttel bodyies, what u want stock ? ported ? i have some that have the flap polished, also u ant a dx ? or and z6 ? let m eknow andPM me yourplace were u want me to send it to, thanks TK and we just bought this kit for 200$ ,complete kit so ---- if i can make the 70 HP cx a TAD FASTER for 200$ and no more then why not. but yeah so u think i will make it any faster without fuel managment ? how many APPROX ponies should i get , the turbo is like new o shaft play, and i have mounted a DSM intercooer i me fender, and have a greedy type-rs BOV { CAME WITH} and hav oil coming from blcok with no restricter and out to oil pan with big line. what can i get 20 30 40 50 60 horsepower on a NON FUEL MANAGED USED D15B8 ? i know u cant be accurate but estimate ? oh andi pu o some got boost stickers so thats 5WHP RIGHT AYWAY , , , , , LOL |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
honestly your going to blow your engine probably imediately if you dont have any management at 8psi at least throw in a pump and a 10:1 fmu it would take like 30 mins to install both of them and it will actually run for a little while. get a used vortech fmu even 12:1 would work. get a walbro 255lph pump. if i still had my fmu id give it to you but i dont have a pump or fmu. and if you get a ecu and injectors it takes the same amount of time to install and it would run a hell of alot better and last 4X longer on just a basemap. i cant explain how important it is for fuel management on a turbo engine.
If you run a basemap and injectors w/ 8psi you could get anywhere between 45-80hp increase depending on the map and setup probably 50hp but w/o management you get a broken engine http://www.-------------/catalog/chip...cus-p-277.html = chipping kit w/450cc injectors or http://www.-------------/catalog/chip...ecu-p-154.html = chipped ecu with ectune or chrome and some450 cc injectors Walbro pumps and fmu's are found on ebay and plenty of other places As for the throttle body if you got a ported z6 laying around that would be awesome but ill take anything that will work on my engine obd1 92-95 |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
ok sounds good,
yeah ihave aported z6 2 of them i can send u 1, its from a 94 delsol si, so OBD-1,,, QUESTION: myBOV is it ok if i hook it up to the PC VALVE POR on the INTAKE MNI ? and can i hook up the boost aguge to the fuel preasure line and T it off ? and if i n hook the fuel preasue regulator will i get more fuel ? is it better then nothing ? an i dont cae if it blows as its not mine eactely it my buddiesbut i will tell himabout this, but if he decides to buy it or not i dont know LOL, but yeah ill send out friday ups, and let m eknow on the above, and last what octane should i run ? 93 like on ll of them or can i do e-85 ? |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
ok get some management unhooking your regulator is not a good idea and hook both your bov and boost guage to t's on the fpr vacuum line

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
OK BRO, i di wa u sai,i canked it to 14 psi ON ACCIDENT, and blew my intercooler piping as didnt have it tight on there, ONLY TOOK IT TO 3.5 RPM and it made FULL BOSST !! BOOST=DRUG, LOL anywase thankyou i sent out your T-bod cost me like 4$ so no biggy, and now
DONT worry iturned it down to 4 , i have compressor surge, should i make the turbo SOFT ? also, my trbo on the weld there is a VERY SMALL TIRNY exhaust leak, can i use jb weld or should i use exhaust fix weld stuff ?? and last, it didnt bog down, idealedpefect everything runs perfect i might not need fuel managment, just put in fuel pump bigger, also HOW long should i let the turbo spool down ? i dont have a timer yet so, and also does HEAT wrap help ? ICANT find a FILTER that fits my turbo which is liek littel over 1 inch LOL, ill pot pictures and video ok ? and u will get yor T-body wednesday the guy said, thanks |

didi you send that $25

Thanks for the t-body ill let ya know when i get it Deff post some pics and vid. |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
i ran the ---- out of it , everything works GREAT,
BUT i am getting BACKFIREING when downshift, and i turned the BOV all the way to SOFT, and still have compressor surge, MABEY thats how the BOV sounds ? ill post a video mabey, but yeah the engine had 65HP nowfeels like my H22 swaped hatch , LOL ok man thanks ALSO i used E-85 , just to try it out and it akes my car shut of on a redlight, and so with 90 it run great, so should i run which grade as u think ? and if i have WHITE SMOKE coming from exhaust on 6-9k revving then whats that mean ? i have NO BLACK smoke at all, thanks |

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
No ----. 95% of this is covered in a BASIC, UNIVERSAL TURBO FAQ. The other 4.9% is a basic Honda-only TURBO FAQ, the last .1% is setup-specific.
The truth is you should stop worrying about crap like small exhaust leaks or engine bay temps, and focus on the most importing aspects such as how the motor gets fuel, and how the turbo system actually works. Research "TURBO CARNAGE" for a better idea why you should learn all this before you even BUY the parts. :1 |
Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
a6 or b7 head yes there both the same. if you use a a6 head you will need either and adjustable cam gear or a y7 cam gear. the b7/a6/z6/b8 will all be off by half a tooth. head and ecu will net u 30hp for under 100 bucks at a local junkyard. your bottom end can take about 200whp on a really good tune so if ur running somthing shaddy like fmu i wouldnt push much past 160whp or go any higher than 180whp on a basemap.

Re: D15B8 IHI TURBO, CAN I HAVE SOME INPUT ?? IM NOT MAKING BOOST !
spoon feeding but if i get the throttle body then it is worth it :6
