Saturated injectors are used in almost all-standard production, 1998, engines because of the system cost and simplicity. Saturated based systems usually fire all injectors at the same time, once every rotation discharging half of the required fuel per cycle at each event. Some systems fire half of the injectors at one time and the other half at a different time. These systems are called "Batch Fire" and "Semi-Batch Fire " respectively. This system is used in 90 % of all general production engines (cost and simplicity). In almost every case Manufactures will only use Peak and hold injectors in High Performance applications or in Turbo applications. This is true in the Ford/Mazda family, Chrysler/Mitsubishi family, Nissan Group and the Honda/Acura folks as of 1997. General Motors/Toyota cars are also in this same family. OEM APPLICATIONS GM uses Saturated Rochester injectors in everything but some of the High performance cars, hear they use Lucas Injectors, and in the turbo trucks they use Bosch. Toyota uses saturated injectors in everything but its turbo models - all Nippon-Denso. Honda, last year changed all but the NSX to saturated, most all of Keihin make with some IPT. Nissan uses saturated units only, as of this year, Jecs or Hitachi manufactures. Chrysler/Mitsubishi - same deal - all but the turbos are saturated, Siemens or Bendix make. Ford uses Bosch or Nippon-Denso depending on the Model. All are Sat. except Turbo Models. Bosch and Lucas injectors are used in VWs.. BMW , Bosch up until this year, now Lucas --- European cars use an assortment of injectors

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
