anyone know what the settings for Xspurt 1000cc are? using a power fc with stock regulator, was given info on the deadtimes and at 14v its 0.990, thats all i have.

my old nismo 555's were - 62.5% 0.18ms

what should the new settings be? 37% 0.990ms

???

I did have the data sheet here but I can't find it. Just give Aznew (Injectors online) a call, they are quite helpful. If you have any issues I can ask them today, I have to go and pick up one of the new Walbro 416's they got in stock for me.

Thats where i bought them, i asked about it and they said all they have is the deadtimes list, so that has 0.990 at 14v

deadtime is same as latency is that right? so its 0.990m/s

if thats right then i just need to work out the first part. What are they charging for the walbro, i didnt know they had them, ive seen them for $190.

They are around the same price then.

I have the dead time report here, that is correct for 43.5 psi but it will climb exponentially the higher the fuel pressure and if the voltage is lower. Most tuners will have used ID's and ev14's before so I doubt you will have any issues.

i was hoping to put them in and start it up this weekend thats all, ive sent an email to the tuner, so hopefully he responds by the weekend.. :yes:

looks like i wont be using the stock reg, just got a turbo smart one, do you still use 43.5psi with 1000cc injectors or do they prefer a bit more pressure?

Standard injectors are 370cc and .63ms

Your new injectors are 1000cc and .99ms

370/1000x100 = 37%

.99-.63 = .36

There's been some debate about the standard injectors latency so I'm not 100% sure about that but it should be close enough to get it running.

      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.
