I have a GTR front diff/sump. After taking the diff cover off i found the crown wheel has 48 teeth (should be 37 for a R32 / R33) and the markings show LS48.11 What is the ratio ? I think it works out at 4.3+.1 ? Strange as i thought R32 & R33 are 4.1 and R34 3.5 Any thoughts please

The 48:11 means there are 48 teeth on the crown wheel, and 11 on the pinion. Which is 4.364:1 . And I'm guessing 'LS' means 'Limited Slip'.

The previous owner has obviously changed the gearing for some reason.

yes and standard 32/33 GTR is 4.11:1 (37:9 from memory). the GTS4 35:8 (4.375:1) is a common upgrade as you can get front and rear that fit into a 32 GTR. I can't say I know what comes with a 4.36:1 ratio... if you've been having any AWD problems it's worth checking your rear diff to make sure the ratios match.

Thanks for the replies. I should explain that i have a R32 GTR with standard diffs and purchased this one as a spare (diff & sump) I was just checking the condition and found the odd ratio. Would this diff center fit another nissan diff housing eg. 240K/Skyline ?

It looks like no other ring gear/pinion patterns are compatible with the F160?

There might be something out there, but I'm not aware of it.

Do you know of any, I want to severly drop the ratio up front and put a 3.26 or so in the rear

The closest you'll get in terms of that sort of ratio for both front and rear diffs is from R34 GTR, which is around 3.6 from memory. That's in terms of reasonably readily available, there also might be something aftermarket, of course.

Unfortunately I need lower than the gtr ratio's

      When you crank your car, and hit it with a timing light, can you see a steady crank timing?

      Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
