Hi Fellas,

I currently have 312 rwkw and the injector duty cycle is at 81% (using nismo 555 cc injectors), without a FPR

My aim is to get my power up to 360-370 rwkw. Using basic extrapolation ((0.81 x 365))/312)=94.7%), I get an injector duty cycle of around 94.7%.

However, if I install a Fuel Pressure Regulator (FPR), I will be able to increase the pressure, thus, making the injectors flow a bit more.

Anyway, I need you opinion on what power you think the injector's would max out using a FPR with my 555cc injectors.

My tuner is very confident they will make 360-370rwkw safely, as he has done it before.

Please place your vote!

Cheers

Your vote would be greatly appreciated!

I used 740's - i knew the power i wanted, so i purchased injectors to suit it. :happy:

Im not a fan of FPR's if you've gotta buy injectors, you might as well buy the correct ones as i see it and use one of the better Nissan OEM parts.

For what you need, it'll be fine however to add in a FPR, bump a few PSI and make what you need.

without bumping fuel pressure your 555cc's would probably max out at around 330-340rwk

So generally speaking, how much more power does a FPR provide?

Also, are there any disadvantages to having a fuel pressure rgulator over bigger injectors? (Does it increase the chance of damage to the fuel pump? Or increase the risk of split hoses? Can a FPR damage injectors?)

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
