    Wow, I'm surprised it made such a dramatic difference! You must've had a crappy ignition system beforehand... O2 sensors measure air (Oxygen) concentration in the exhaust stream, with respect to the atmosphere. Less O2 in the exhaust gives a richer reading, no matter how much HC, CO, or CO2 you have in your exhaust. Your meter shows a richer cruise after MJLJ install, meaning you're burning more O2 (and fuel) thus leaving less air in your exhaust stream. Your meter also shows a leaner WOT after install, meaning you're now burning more of the fuel (and O2), enough that the O2 sensor now indicates a lean mix. FWIW...

    The uncertainty is about the valves not being installed. Maybe he temporarily installed them with the old springs and hardware? I'll clarify his procedure when I pick up the engine, and I can always double-check myself once I've lapped the valves and installed new hardware. I should be fine at 10:1 as long as I do a good job on the tune and minimize cylinder-to-cylinder variations. That will remain to be seen.

    Nice job!

    Quick update from machinist: P90 chambers are 44cc. Now I don't know how accurately he cc'd them, but I was expecting closer to 46cc. Thus, my compression ratio will be just about 10:1 depending on compressed head gasket thickness. This is a bit more than I was anticipating but I think it'll be alright given the nice chambers of the P90 plus the hotter cam. He's shooting to have the machine work and balancing done by early next week.

    Once you've floored it, you're on the main circuit. The only thing that can help there is a proper emulsion tube. The hypojets make the car more tractable and efficient at lower RPM. The butt-dyno feeling is one of more "crispness" and quicker throttle response. Frankly, I've only run the hypojets with Keith's e-tubes so I can't exactly comment on how they feel on their own, but Zedyone Kenobi (or something like that) on CZC got hypos recently and posted his thoughts on that forum.

    No.

    My first thought is, why? This is HybridZ and all, but what would the functional purpose be of a rear transaxle in this car?

    VLSD only came in Shiro editions I believe, but it would be good to clarify.

    I have a couple sets of wheels: http://forums.hybridz.org/topic/112897-wheels-bumpers-dash-door-r180-wiring-harnesses-etc/

    There's one for sale on SF Bay Area Craigslist: http://sfbay.craigslist.org/eby/pts/3862924237.html

    You might be able to register under SB100 but I think that may impose restrictions as far as how the car is used. I'm not well-versed in this so don't quote me. Just skip the political crap please. I don't go to HBZ to discuss pot-growing and what state may be a "dictatorship"...
  12. Leon
    Sure do.

    The reason I recommend hypojets is because they're tunable (that 4-in-1 thing) and Keith will exchange jets. I don't think Weber jet distributors do that, AFAIK. Hypojets really wake up the car, especially on the low end (combine with his e-tubes and it's even better).
  14. Leon
    Those are huge idles. Drop down the orifice size and to a smaller air bleed hole (not sure what F-number that would be). That should lean out your cruise mixture. I recommend Keith Franck's hypojets. They are way better at fuel metering than the Weber ones, plus they're tunable - it's like having 4 jets in one. Going through the process, are now learning the differences between a "running" setup, an OK setup, a good one, and a great one.
  15. Leon
    Yeah, we get it. "Dictatorship..." Please keep your political thoughts to yourself, at least at HybridZ (it's in the rules, after-all). I'm perfectly happy living where I live. Now get outta here you pot-smoking hippie!

    If you get cited for something smog related (e.g. blowing smoke out the tail pipe) you'll be sent to the referee, who will check you off once the issue is taken care of. The referee will know if the engine is non-USA, let alone if it's been swapped and not BAR'd. However, 1975 and older vehicles are exempt from biannual smog testing so people get away with it (until they do something stupid and get sent to the ref).
  17. Leon
    No. It's safe to say that a cammed L28 running lean with retarded timing and a new cat might pass smog. I'd be interested in how that car tests 6-9 months from now...
  18. Leon
    I'd expect to pay at least $6-8k for what you describe.
  19. Leon
    It doesn't matter, you're (technically) not allowed to use an engine that has not been certified for passenger car use within the USA.

    I'm sure the local Z-club can help. We have a lot of members in NY and I think Clive (EvilC) is the president of the NYZCC.

    Got a polished and balanced crank yesterday (thanks to stravi757)! It'll go into the shop for a quick re-polish (specs of surface rust on some journals) and probably check the balance just to be sure.
  22. Leon
    Crank purchased. Thanks!
  23. Leon
    Yeah, I linked that for him too. The thing is that the same link is on the atlanticz website...

    I don't have a specific number in mind, but as close as I can get away with. I'd be happy with .025-.030".

    I'd recommend a straight (not bent) intake. You can either have a straight runner with a taper/bell mouth at the end, or a fully tapered runner. Options for length tuning are nice (bolt-on air horns). Offer different head flange IDs (40mm, 45mm). Bosses for fuel rail mounts and vacuum taps for each runner might be nice as well.
