   Twin Turbo L28 1 2

   Been doing a bit of Z reading up lately (I am a Z anorak, I know ) on different performance upgrades that specialists have offered for our Z's. Stumbled on 1 company called Cartech in the US, apparently they offer/offered (not sure if they still do it) an L28 conversion which featured twin turbochargers feeding a plenum chamber that formed the airbox for three choke Mikuni Carbs. Anyone else heard of them?? Anyone else got this setup?? Anyone got any links with more info?? Power is reputed to be in the 350bhp region. Why haven't we all got this? Janspeed offered a conversion featuring a Roto-Master Turbo. Standard FI was retained with two extra fuel injectors added…

   remove/replace oil pump

   Guys, I'm slowly addressing all of the little problems on my Z and next on the list is the grimy, oily oil pump. Its obviously leaking or weeping from one of the gaskets/seals and needs attention. Are there any tricks to removing and replacing the oil pump? My Nissan workshop manual mentions that the Distributor must be removed first... I'd rather leave it alone if at all possible. Your thoughts? Hayden.

   What does it mean when there is tiny little bubbles in the oil or on the dipstick when I pull it out. Also would anybody know about the lock up on an automatic tranny, a mechanic I took it to told me about it but didnt explain it very well, and my car has been overheating still and I was thinking it could be the lock up on the tranny. Thanks

    Puff of Smoke

    Okay folks, I got the 73 out of winter storage and drove it today. I primed the oiling system first then fired her up. As I was driving I noticed a puff of smoke out the exhaust in between shifts. Anyone have a guess as to where the oil is getting in at. I would guess a valve stem seal. Havent run a compression check yet. Car was great before put away for winter. All gauges good while running. Could it be a PVC valve issue pulling some weird issue under the valve cover? No smoke while idling or under throttle in any gear, just between shifts. Thanks in advance.

    distributor question

    March 18, 2004 by malder

    How much play does your distributor rotor have? I know there is some centrifugal advance that will move if you really twist it, but I'm talking about just turning the rotor with minimal pressure. I am asking becausemy rotor has about ~5-10 degrees of play. I am just wondering if this is making it difficult to get the engine timing just right. thanks Matt
