I'd go 1000's, straight up.

i would buddy but theres like a 500bux differnece in price, bitch of a cold start and exhaust idle. =[

Would 1000cc Sards be ok to Run a 26/30 on E85 pushing 400-500kw?

Sorry to hijack

theyd be fine, only reason im asking is maybe they might be to overkill.

I went with 750's and now looking at having to move them on for something bigger - given hindshight I would have saved money if I'd gone 1000's first time around.

What ecu are you using to be concerned about injector control?

I would go 1000cc, low impedance. Trying to make motor with 1000cc, high impedance, injectors idle would be an absolute prick.

The reaction time of a low impedance injector is a lot faster, hence the motor will idle more smoothly, than if you were to use a high impedance injector.

im in the same boat, in the sard range there are 2 options:

1. black top/orange tip, lag time 1m/s

2. light blue top/green tip, lag time .85m/s

is the 1st injector low impedence you are referring to?

i run 1000cc sards and bigger cams than mentioned and idle is no problem at all. cold start idle was never the greatest but i aint running the idle air control valve any more and never really cared as it wasnt a daily driver. I had to keep the revs up a touch for 30 secs and then it idled itself fine, dont think this is the injectors fault though.

1000's in a 14mm fuel rail. 1600's if you want to run e85. i have 1000's and at 376kw they are on 75-80% cheaper to get 1 set not having to buy smaller ones only to run out of RELIABLE headroom..

1000's idle perfect, just depends on your tune,, oh and ecu

      Starting again

      Had another look at the car and I noticed the fuel pump isn't priming on ignition. I'd taken out the pump from the boot to siphon out the old fuel, so maybe I've knocked something loose or broken a wire putting things back together. Will go back with a multimeter and try to work out what's stuffed. Kinda hoping it's the pump itself thats gone so I can upgrade it

      Yeah agreed, you can't assume that shop are they only people who ever had to work on it. It was just a guess on the mods based on how things were done back then. You can check the Air Flow Meters by the part number on their tags, they are likely either Z32 or Nismo ones (both read about the same but the Z32 one is a little larger while nismo is stock size but supports the higher airflow like a Z32). And yes, all that would get you to 450hp / 340kw To tell what is happening with the turbos, you want a photo of the tag on the core, that will say what it was made out of  (they can retain the front and rear covers to make the plumbing easier)

      1992 R32 GT-R Race Car

      By bardabe · Posted

      I'm selling my personal race car. 1992 BNR32 Skyline GT-R About eight years ago the engine developed the dreaded low oil pressure problem. I removed it and found the issue. However shortly after I moved half way across the country, moved my work shop, bought a house, got married, then moved my shop again to it's permanent location for the time being. in turn I do not have the time to race this car as it should be. In turn the engine I built for this car will end up in my street car and this car I hope finds a home with someone who can use it to it's full potential. The roll bar was built by Jason Noren Fabricaiton in Pomona California to SCCA and NASA Specs. The car used to compete in redline time attack and global time attack enthusiast class. It also has a fire suppression system.  The car is with me at my workshop in Kyle Texas, USA. Shipping it is no problem, I can personally deliver the car to the port of either Houston or Los Angeles. Any other port depending on where it is may require transport but we can always work that out.   The chassis itself is rust free, rear quarters and under fenders are free of any rust so it's a very solid foundation for anyone who wishes to move forward with it. As posted and at the asking price of $20,000 USD the car includes all of the following;   All OEM Body panels, front fenders, rear bumpers etc.  OEM Nissan Projector headlamps (Pictured N1 lamps were removed) OEM Nismo Side Skirts / Extensions OEM Rear Spats  Front & Rear Subframes are installed car is full roller Rear Subframe has Cusco Camber Arms, Whiteline HICAS Elimination Front Subframe has Whiteline tension rods and whiteline Sway bars w/ endlinks.  Buddy Club N1 Coilovers All chassis wiring and engine wiring is in tact. Attessa System is fully in tact and was functional before engine removal.  BCNR33 GT-R Brembo Brakes F+R with Endless MX72 Plus Pads, DBA Rotors & Stainless Steel Brake lines Billion Racing Radiator Billion Radiator Hoses Fluidyne Engine Oil Cooler Accusump System (trunk Mounted) 5 Speed Transmission w/ Transfer Case F+R Prop-shafts Rear Differential With rear Axles.  Nismo Gauge Cluster Nismo Clutch + Flywheel   Essentially what is needed to make this car running and driving again is as follows: A working Engine, an ECU, and time to put it together. The price posted is or best offer as I am willing to remove some components to accommodate price to a certain extent. If any serious buyer wants full detailed pictures, videos, or any questions I'll be happy to answer them. I believe this car is priced to move quickly considering it's a rust free and very straight chassis but always open to fair negotiation.  I can be contacted via phone or email. (+19517081648) email is juan@bardabe.com

      Some more info I found.  These are the last entries Yoshikiyo Fujii made on his blog before he passed away in 2009: http://blog.livedoor.jp/fujii_dynamics/ And finally this is where the workshop was situated:  https://maps.app.goo.gl/HhTPtHzt3WVcBTiEA
