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

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......

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. ;)
