Heaps stiffer, no more groaning over kerbs either

I cant say as far as the handling goes because last time I drove it before the cage it was practically stock

[doo0T!doo0T!]

Oh yeah and on another note.....

I goes doo0T!dooooooo00000T! hondata FTW.

I finally got my obd1 re-wire job sorted out properly after a whole day of chasing a no-spark problem and hey presto, leaned in the window, turned the key and away she went.

I dont usually like to brag but I'd just like to say this....
Fuck I'm the Man. 8)

Not one single wiring problem, I am so stoked with myself, the obd1 ecu is hardwired into the OBD0 loom, so is the obd1 dizzy and it's working sweet as.
I get a code 8 for TDC sensor but I am certain thats because I am a tooth out, I just changed the cams and was a bit 50-50 about whether I'd got the timing right.
Still idles fine though despite the lumpy bump sticks.

The new cams have a buttload more lift than before, the lifter adjustment screws are adjusted almost flush with the top of the lock nut when they stick up about 4mm with stock cams.
Now I see why Trenchrat had to make custom lifters, they wont take much more lift than I've given them, especially on re-grinds with a smaller base circle.

Its currently running on a D16a1 stock tune modified for 560cc injectors and the duty cycle at idle is only 1-2%!!

I also went to Pioneer today and got another MSD cap so the Mallory and blaster 2 are up and running again.
I have finally put some filtration on it too, I wish I had a camera, I have run brake ducting from the turbo up and over where the washer bottle sits and have taken out the head light. A poddy now pokes slightly out the hole where the light would be. It's pretty rangimods but shit it'll do for NIMM.

Now all I have to do now is run all the wiring and switches for hi/low boost, launch control, data logging and full throttle shift.
oh and chase all the strange earthing problems with those pesky gauges.

This is going to be one angry mother crx if it ever makes it to NIMM :evil:
Things are starting to look more promising, i only hope the boost solenoid and 3 bar Map get here in time. 8O

[Bananaman]

Sounds like you are well ontop of things Mike. Can't wait to see the progression from mean street to BEAST!

Are you going to dyno it before NIMM?

[nzcivicracer]

Awesome dude, stoked you got it sussed 8)

How does it sound, any hint of bigger cams in there?

I found a thread on thezcr the other day, talked about putting B18B valve springs into the ZC head. A bit of milling required but meant it is easier to run bigger cams, plus have a better choice of valve springs 8)

congrats on the good wiring job

For sure, Speedfactor in tauranga, probably Thursday and go straight to taupo from there.
I have a land crusier I can borrow to tow it just have to suss out a trailer.....

It's hard to say whether it's the cams or a rough idle but it definately cycles/pulses a bit more than it used to and shakes a bit, certainly not as smooth as it was. I'll know for sure once it's tuned and smoothed out.

I have some bigger springs out of a 4g63 mitsi, I havn't put them in yet as there is no real need, I'm not going to be revving this engine hard.
The next motor will get the springs though.

[nzcivicracer]

Cool man. Shot gun a ride at NIMM if your allowed passengers 8)

^^ unfortunateoly i dont think he will be, you need a ful manz approved caged

Which is a load of cock and you can quote me on that.

It's built to MANZ spec and I can prove it so what's the problem? I can see why boltins could be a bit of a worry but this is no bolt in.

yeah well i spose you could argue what does approved mean.. built to specs approved by msnz??
because msnz approves cages via homologation.. you think if they wanted homo cages they wuld use that word

secondly, i could be wrong but dont you need a "full" cage - ie 6 points--front roll bars??

i guess you find out on the day ay??

Yeah you're probably right, mine is 6-point but it only has the one hoop.
For now.......

[DURTYEF3]

Good shit Mike, will be good to catchup @ NIMM, and hopefully the CRX is there, havnt seen it yet.

[doo0T!doo0T!]

Holy shit a lot has happened since the last update here..

Last weekend i carboned the roof to stop the filler cracking over the patch where the sunroof used to be, looks great pretty happy with it, a few air bubbles but not to worry.
Pics tomorrow.

I was out at strongs getting some shit for the Eg and saw this massive veilside wing on a CRX and thought I just have to have it as a bit of a piss take, it's actually higher than the roof
I whacked a bit of black paint on it and fitted it up rigth before leaving for NIMM. Wasn't going to say anything beforehand as it was supposed to be a joke but i think everyone thought it was for real.
The funny thing is though the car stuck to the road better at speed with the wing on. It actually works, the difference with and without the wing is quite noticable. I think I might bolt it back on for the next rack day too. Maybe it's not as much of a pisstake as i intended it to be.

NIMM started for me on Thursday morning when I left Auckland bound for Tauranga for a tune at speedfactor.
Things got a little complicated, a cyl sensor polarity problem with the dizzy wiring meant I was at Speedfactor for 11 hours mostly working away on the car in the yard before finally getting it running at about 7:30 pm with help from Jono Lin and Evan.
The problem had everyone stumped and the wiring solution goes against all the online wiring guides for OBD1 conversions. basically how it is now the cyl sensor is wired up backwards but it's working perfectly, prior to that it would throw an intant code 8 on start up.

Got it onto the dyno asap where a few of the boys were sinking a few bourbons and after a few hours and countless runs it managed to lay down 160wkw and 569NM of torque at 13.5psi!!
Totally stoked with that, thats pretty sweet going for a decompressed ZC and a tiny T25.
Some of the backfires the car did on the dyno were mind blowingly loud, like being donkey kicked in the guts and I swear there was a flame a metre long out the side of the car with one of them.
There was no detonation at all and no temp problems developing either.

Left speedfactor at 10:30pm, massive props to Evan, Lin and Jono for bending over backwards to accomodate me and make sure I got to NIMM with it raceable.
I cant speak highly enough of those guys and I will recommend Speedfactor to anyone in the Future.
It was genuinely refreshing to deal with a workshop full of professionals who really knew what they were doing, would listen to what i had to say and were prepared to give up their whole evening to make sure the job gets done properly rather than show me the door when 5pm rolls around. Hell they even offerred me dinner.
Speedfactor gets a big :thumbsup: :thumbsup: :thumbsup: in my book.

Finally rolled into Taupo at about 1am to find Timmiblc and Frost waiting at the gate, beers in hands pissed off their tits.

I was late to scrutineering because I had to chase all over Taupo looking for a bosch GT40 coil as we found my MSD blaster was poos on the dyno and was creating big missfire problems.
Finally found one, probably the only one in town, and got to scrutineering 10 mns before the shed doors closed.

Getting the car off the trailer drew a bit of a crowd as it was running super rich on cold idle (we never got to set the cold idle fuel trim) and it was idling real dirty and belching black smoke.
Sorry to those of you who introduced yourselves there and then i was stressed as hell and cant remember who i talked to. ops:

It weighed in at 883kg with a near full tank of gas on Evans 4 corner scales so based off that and a 15% drive train loss it's boasting a pretty respectable power to weight ratio of 4.9kg/kw or 281hp/tonne 8)

I missed my first heat as i was too busy with the spanners in the pit garage but when it was finally time to roll out by christ did the car fly!
It had no traction in 1st and 2nd, 2nd gear would light up both front wheels out of corners and third at lower rpm would over boost so i had a hell of a time juggling the massive torque steer, swap from under to over steer and vise versa as boost built and dropped.
The back straight was real fast, the needle was maxxed out on the pin past 190 and i was seeing the revlimiter in 4th just before getting on the picks at the end.
I have no idea how fast I was going.

I made the mistake of getting carried away in the moment and let it over heat, I should have been a lot gentler on the first outing but it was so fun i couldn't help myself.
My ride came to an end when the manifold blew out and the header tank popped basicaly simultaneously and that was the end of my driving at NIMM.
Got towed back in by the Wong bus with my tail between my legs.

At least I got to drive it and at least the missus finally got her spin in it around the track. She left permanent holes in the fabric of the passenger seat from her death grip with her fingernails.

It'll be back soon, just got to make a new ext manifold and it'll be on like donkey kong.
Just got to let the bank balence recover, NIMM worked out to be about $250-$300 per lap for me by the time I add up trailer hire, accomodation, fuel, damages, tune, last minute parts purchases and getting the tow vehicle road worthy.

[SLOTEG]

good to see you again mike, even if i only said 5 words to ya, as you were super busy ops:
car sounded AWESOME on the track, definately knew who was coming at the end of the front strait, all i could hear was rooooaaaaaarrr / backfire backfire change gear / roaaaaaaaarrrrrrr / backfire tire-squeel around the corner backfire / rooooaaaarrrrrrrr :twisted:
sucks about the problems ya had tho
looking forward to seeing it eat the track up again :thumbsup:

[Bigelboe]

Thing was savage as :thumbsup: Pretty good weight you got it down to aswell, especially with the 6-point.

EDIT: Pic of the damage

[lofreq]

looks like it wnt out in style..! that manifold's certainly done its duty and service boosting zcs for like 10yrs now

hope u had fun mike lookin fwd to you havin more fun wih the next evolution of the project!!

[mit5u]

was awesome seeing this thing in the flesh on friday

shame it didn't get a bigger run but it did sound awesome on song 8)

[mr.sky]

What is your actual torque at the wheels matey? 569Nm sounds like a raw figure. My skyline only had 450Nm at the rear wheels (252wkw). Hard to believe a 1600cc has more torque than a 2500cc :-)

Great read anyway been following your build for a while :thumbsup: :thumbsup:

drivetrain loss and different dyno readings too...

and honda turbo'd have rediculous torque...

the d16 is already pretty torquey due to rod to stroke ratio .. slap a turbo onto that ... and BAM!

and the torque on my turbo D is rediculous.. lifts the front end massively (well you know what i mean...

[Bananaman]

Post up your dyno sheet Mike, keen to take a look

I'd agree with mrsky... I find it hard to believe 569Nm of torque from a 1.6. Thats comparing with normal manufacturers torque outputs. And if you look at it logically.... How could an engine with 900cc less, a smaller turbo, less boost, and 90 wkw less put out alot more torque?

[d16a7]

its all in the drive ratio's in the gearbox... and a whole bunch of other stuff...

im guessing 3rd gear on the RB25 would wind out to around 160-165 whereas the little D box would only go to 140...

so its all in the way the motor puts the power through the gearbox..

im not prepared to go into this all but my mate with a rb25det skyline took a ride in my car and said it FELT more torquey than his skyline... although on a straight engine dyno with no gearbox would probably be a totally different story...

i would agree with that

It the usual story of it being a at the wheels reading need to divide by the gear ratio to see the actuall figure.

Oh and well done Mike good numbers 8)

[DURTYEF3]

Very nice to see out on the track for the first time and in the flesh!

Went well mike and i recieved a backfire to the face coming down the front straight (i was hanging my head out the side of the flag hole 8) )

Ashame you didnt get anymore time with it, but im sure you will in furture

You going to be at Night Speed Drags wars this week?

Maybe someone needs to bring a mobile welder to NIMM '08 :wink:
