Holy cow dude did you even look in this forum? im not bashing you ... but if you just read the sticky thread in this forum your answers are there. i have a 260 (same as a 280) with a rb26 installed and it fits fine.
10K plus is what you will need and that may not even get you on the road if you cant fabricate.
the stock internal can handle up to around 550 rwhp with fuel and turbo upgrades
If I remember right what happens is the oil gets foamed up and it also acts like a tornado and draw the oil out of the pan. Once this happens you start starving the motor of oil and boom. I know track RBs get seriously worked over in the oil system department so they will survive road course abuse.
Good example is that duralube or whatever demo you see in schucks. in the that clear box with the gears. If you turn if fast it draws up oil out of the bottem. If you can amagine it going 8000RPM well you get the picture.
Mine ended up being 51 front 49 rear with the RB 26 in it for total of 2750 with me not in the car and no gas in the tank. Mine was gutted with a stock dash with no heater core, one FRP racing seat and a mild steel 10 point cage.
I came in about halfway thru. And was wondering about all the talk it took about 5 minutes of watching before I found out what was going on. I came in right as pit stops were happening when shummie almost took out barricelo coming out of the pits. THAT would have been hilarious.
Loosing intereste quick
havent decided yet. its either going to be 920cc or 1000cc injectors just depends on pricing.... i have heard the 4 digit injectors start getting real expensive
Dont know what the duty cycle was but we had to turn the Fuel pressure way up to keep it from getting too lean on the top end. It made 610RWHP .... I think if i really pushed them may have gotten 650 but i think they were close to being maxed. And just using all the math formulas for figuring injector size for projected HP says there too small.
Smack me around but i wasnt sure how to list these in the classifieds if its an auction. min bid starts at 375.00 Need to upgrade my injectors and these wont do it anymore.
they are top feed Denso injectors and will fit most top feed applications. they came out of my RB26.
