New member, unique crx with a problem *FIXED!*
 

Hey glad to be a new member here, I was reffered to this place by the friendly people on RedPepperracing.com

Here's my story,
I've been every close to dropping my b18b motor in my 86 CRX Si but an oppotunity arose that I had to take advantage of and ended up selling most of the things I had collected to do my swap including the b18b and purchased this new car.....
Attachment 32447
Attachment 32448

Here's the setup

92-93 OBDI JDM B16a From the integra xsi. 170hp, 10:4 comp, ~80k miles. Brand new timing belt/oil pump at time of swap.
YS1 tranny with no grinds
Brand new Stage 3 6puck double sprung stage 3 clutch and 8lb flywheel
Hasport motor mounts
Crane stage 1 cams and COMPLETE valvetrain
aem cam gears
BRAND NEW GT32 Turbo w/78ar. internally gated at 8psi
LSD motorsports log manifold
johnny race car 6" intercooler
Precision 440's
stealthmode oil line kit
HF half radiator and slim fan(car runs cooooool)
2.5" mandrel bent intercooler piping
HKS "style" blow off valve
2.25" open downpipe (couldnt fit any bigger due to major room constraints)
OBDI PR3 ECU tuned by xenocron w/crome pro

Here's the problem which has eluded the previous owner for close to half a year now and the reason why he sold it to me;

Engine breaks up/misfires in most RPM's and will not rev past 6500-6700rpm. Also throwing a VSS code, speedo has never worked and accoding to the owner both things have never affected the car. It was tuned by xenocron and doesn't have its own tune just a base map. The car started behaving like this after a boost spike which blew a charge pipe but the car runs and drives anywhere, compression is 210 in each cylinder and leak down is fine. The MAP sensor has been replaced with I assume an OEM along with a TPS, Distributor king Dist, 2 other chips put in with no changes, and the 02 sensor remains uplugged because supposedly it runs much better this way :l can't imagine it being worse than it already is. I'm very new to this, so sorry if I ask a lot of questions this is only my third car ever. I'm going to be taking it back to xenocron to see what he can figure out but I'd like to hear some no bullshit responses/therories unlike what I've gotten at my short visit at honda-tech. I will do my best to answer any questions at all to aid in trouble shooting. Only thing I have discovered since bringing it home is that with the full exhaust now put on, it doesn't even sound like a honda.....more like a subaru wrx or a chopper. I'm gonna pull each plug wire and find out if I have a dead cylinder for sure, Thanks and glad to be part of forum, TT

Re: New member, unique crx with a problem
 

that does sound like a dead cylinder...try pulling your spark plug wires off one by one to isolate the bad cylinder...then check that wires that injector or that plug to see if its any good...maybe check your firing order too...try that good luck


check the gapping also

Re: New member, unique crx with a problem
 

yea doubtful its firing problem sounds like a shitty or clogged injector .. after full throttle run does one plug look diff from the rest??? also check your gap .. should be a .028

Re: New member, unique crx with a problem
 

Alright well I took a good look today and started pulling each plug wire while it was running, I was cut short by a few errands that needed to be run but unplugging #1 made no difference and unplugging #2 made a slight difference. I pulled the plugs and I can post pictures if requested, #1-Dry black and sooty, #2 black and wet, #3 Black and Wet, #4 Dry black and sooty.
My buddy also pointed out that while running the timing belt was shaking a decent amount and when turned off the belt has about an inch maybe a little more of play. Is it possible that when the overboost occured the tensioner loosened or broke and the timing hoped 2 or 3 teeth? Thats all for now, Thanks

Re: New member, unique crx with a problem
 

make a video of the cra running and reving and driving for us

Re: New member, unique crx with a problem
 

its possible bro but not likely .. post pictures of the plugs and replace the o rings on the bottom of the valve cover sunds like 2&3 might be getting oil soaked, id double check yor timing but my ---- was off about four teeth and it still ran and rev'd all the way to 8400 it was just slow as piss ... all honesty though it sounds like tps :y id try a tps then take pictures of the plugs .. if the guy didnt tell you it was replaced it probly wasnt

Re: New member, unique crx with a problem
 

I had a similar problem like this once. checked the plugs and gapped them down. sputtering went away.

Re: New member, unique crx with a problem
 

Like I said the TPS was replaced and I have the original in a baggy. I will take pictures of the plugs tommorow and upload a video of it running and driving. Have one update, I tighened up the belt tensioner, cleaned off the plugs and hooked up my buddy's d16z6 ECU. It ran so shitty I couldn't even rev it past 1500rpm so I gave up on that immediately, I figured that wouldn't work lol. So now I have the b16 ecu hooked back up and now it won't even idle, hopefully thats because its so shitted up from running the d16z6 ECU.

Re: New member, unique crx with a problem
 

Here's video of it driving, pics of plugs and revving it still to 6500rpm to come......

Re: New member, unique crx with a problem
 

I know why the VSS code is coming up and your speedo isn't working. The cable that makes your speedo work isn't plugged into your tranny. And your VSS works off that. You can find the cable on the back of the tranny. Plug it in and it will work. ;)

Re: New member, unique crx with a problem
 

aint that some ----! U said u changed the tps sensor i know, but get a multi meter and check your voltage output at the ecu to see if your getting the wright signal there. also through in some new ngks for the hell of it.

your fine at WOT, you could also have a vacume leak somwhere

Re: New member, unique crx with a problem
 

nah a vacuum leak might make it run shitty but not sputter out like that .. also if it had a vacc leak it would have a boost leak .. is it just me of is it not even hitting vtec ... ur ecu may be in limp mode

Re: New member, unique crx with a problem
 

I can't tell and the last owner said vtec isn't an issue but I never heard or felt it while driving :l IDK

Re: New member, unique crx with a problem
 

lol did the disable closed loop mod .. if not ..lol vix your codes and see what happens

Re: New member, unique crx with a problem
 

I would def check your voltage at your tps and calibrate/adjust it.

Re: New member, unique crx with a problem
 

what ecu is in it, what program is running it?

Re: New member, unique crx with a problem
 

get any code figured out before you attempt to figure this out. i hate these threads, "yeah, i have a CEL, but i KNOW its not the problem, what else could it be". ::)

Re: New member, unique crx with a problem
 

CEL's bother me very much and its the first thing I usually take care of but in this case the previous owner said himself that the only code it throws, which I have checked to be accurate, is a VSS code and the car ran fine for 2 years like this with no working speedo and a vss code. I will adresss it as soon as time permits though.

Pr3 with street tune by xenocron on chromepro

ososlohatch- You might be on to something there, like stated I'm still learning but I would imagine having the o2 sensor unplugged would substitute for the "mod"? I guess I should probably get a wideband too...

Re: New member, unique crx with a problem
 

Your injectors are fried in two of the cylinders or your resistor box is fried. What probably happend is something grounded out to the frame and fried the injectors or resistor box because the resistor box in the older hondas like that is grounded to the frame. The reason I say that is becasue a buddy of mine (B20Accord) had the same problem on his '86 accord after a severe grounding issue. Replace both of those and then see how it runs. Try the injectors first that's what fried on his.

Re: New member, unique crx with a problem
 

Re: New member, unique crx with a problem
 

Right well that means I'm gonna have to call the second last owner and ask him what the hell is going on with the VSS wiring in this rats nest, fun stuff when your working 50hrs a week second shift.

Only cylinders I haven't found wet with fuel up to this point is #4 and I was told these injectors don't need a resistor box.

Re: New member, unique crx with a problem
 

Right well I didn't know a VSS code can possibly cause VTEC to not engage, I also have no idea how the VSS is wired up on this car as mentioned above but.....lol....I just went oustside with a flash light for shits and felt around the top of the tranny and felt what I believe to be the whole VSS unit and it twists left and right freely :P I also needed to connect the actual plug for the VSS too though that didn't seem to do ----. No way this is the fix to my problems but I'll have to wake up way before work one of these days and check it out better. Definitely need some insight on this though.....

Re: New member, unique crx with a problem
 

does your car have a clutch saftey switch?
if u rev a b16 with the clutch in (and posibly not moving) the V-T doesnt come on

Re: New member, unique crx with a problem
 

props for doing this to a 1st gen bro. ;D

Re: New member, unique crx with a problem
 

last time i heard of a turboed honda that sounded like a subaru, there were broken ringlands. And you said there was a boost spike before-hand?

Re: New member, unique crx with a problem
 

Dude you SHOULD fix any problem with your car. Things you think don't matter really do. Like someone else said before Check your TPS and recalibrate it. I took mine off once before and couldn't figure out why it wouldn't rev past 3 grand. that was the problem. Now go fix those things and then come back and tell use whats wrong still.

Re: New member, unique crx with a problem
 

lol 210 compression = not not bad rings

Re: New member, unique crx with a problem
 

wait, your car shouldnt have wires for the VSS, only a cable. you have a cable cluster and a cable driven VSS, if not thats why the speedo doesnt work.

BTW: a VSS code will cause exactly what your car is doing, dont believe me, oh well. FIX THE OBVIOUS.

Re: New member, unique crx with a problem
 

Yes you got it, from what I understand I have a mechanical speedo and an electronic VSS which is going right to the ECU so the speedo is neglected. What I need to do is convert back to mechanical at the tranny, run it to the speedo, and run a different VSS off the cluster which will send the signal to the ECU, right? I do believe you thats the reason I went out in the dark to look at my VSS, if this fixes the problem you get a BIG damn cookie :P I just don't see it being this simple, oh and the last owner said the VSS was disconnected to rule it out as a possibilty.

Re: New member, unique crx with a problem
 

sounds like the last owner does not know his ----, I would not trust him on anything he said, fix your ---- and get back to us

Re: New member, unique crx with a problem
 

my 89 turbo stang does the same thing, well, used to, if i still had a MAF ...that's what i found to be the issue, but then again ...i know dittly squat about hondas,

you don't have an A/F gauge ?

do these things even have an air flow meter ?

Re: New member, unique crx with a problem
 

No A/F gauge nor boost gauge which is already on it's way, it was parted out before I showed interest in the car. I'm going to do what I can to tie up these loose ends that we have discussed once the sun comes up, we'll see how it goes.

Re: New member, unique crx with a problem
 

Damn rain >:( will do it tommorow. Previous owner sent me a message saying Chromopro has a setting that disables the need for a VSS signal to engage vtec, didn't say whether thats in effect or not though.

Re: New member, unique crx with a problem
 

hf crx's of that year 85 to 87 have vss built into the cluster.

you need to swap out the speedo on the cluster to an hf, and then splice the wires into the ecu.
87 si's didn't come with vss

i just put the whole hf cluster into our 87 inorder to run obd0 for turbo edit.

Re: New member, unique crx with a problem
 

Well he's the one who installed and bought everything for the turbo setup so he has to know his ----, though if he REALLY
knew I guess he'd stil own the car. I've been contemplating bringing it back to N/A to simplify things, besides it ran a 14.3 on azenis N/A, good starting point. As soon as the rain passes I'm attacking it, wish me luck :-\

Re: New member, unique crx with a problem
 

lol that is the gayest thing i have ever read ... your lack of knowledge has nothing to do with your turbo kit .. u just dont know what your doing ;) :-*

Re: New member, unique crx with a problem
 

No what I was implying is that he did his homework and probably knows his ---- because he chose each individual item in the turbo setup, installed them and got succesful results. It wasn't a kit from a company or a suggestions from someone else, also keep in mind that before the overboost it worked perfectly I've seen video.

Now, today I fixed the vss code by cleaning the VSS connectors and securing the unit better, I also recalibrated the TPS and nothing has changed.

Re: New member, unique crx with a problem
 

Stumped? :P

Re: New member, unique crx with a problem
 

Did you replace the resistor box and injectors? Stick a voltmeter on the injectors and make sure they are all getting power. If that is the case then replace the injectors.

Re: New member, unique crx with a problem
 

We have progress! ;D Although I found the timing belt had a little play the last owner said he checked the timing so I could cross that off the list.........well I checked it myself this morning and guess what? Yep was off about 3-4 teeth, must have happened when the overboost occured, which he though was VERY unlikely. So now it sounds like a real car and goes to 9000rpm, except for one thing........it never puts you back in your seat ??? It sounds really ------- mean but just doesn't get out of it's own way, any ideas? I'm thinking its a mix of 3 things, turbo isn't right for the application, needs it's own tune on a dyno by like Jeff Evans, Vtec possibly not engaging still. Thanks for all the help I'm halfway there now, TT
