Is there enough to be gained from Cam Gears to make them worth the hassle on my Tomei poncams? I've read mixed reviews on the gains not being worth the tuning time and risking not tightening them properly when going between degrees on the dyno.

Thoughts?

Any material difference between tomei and HKS cam gears?

for memory the old style hks ones were crap and the bolt would slip on the face of the gear,

could be wrong thiugh

I've heard the new ones are better.. I just stuck with the tomei ones

The early HKS ( green/purple) the gear ring was made of a softer material and would wear down and skip teeth, I had this happen lucky it was only 2 teeth and it didn't do any damage, I still have them but can not upload pics

Cam gears on RB26 is one of the best value upgrades you can do, IF you have them dialed in properly

I settled for the Tomei ones and dialed them in at 2 degrees advance on the IN and 2 degrees retard on the EX.Will compare dynos vs stock and decide what to do from there. Re-dialing them in as not as easy as I thought.

Please elaborate Mr Shepherd. They're a good upgrade over stock that's for sure.

The type Bs will give some extra peak power on the dyno but will do so at the cost of low end response and overall drive which is what adjusting the cam gears reduces, in a drag race two GTRs with the same simple bolt ons setup the same, one with stock cams and one with type Bs and both with their cams dialed in properly and everything being equal, the one with stock cams will win

no they aren't, they cost way to much in the bottom end of the rev range for tiny amount of gain they give in the top end of the rev range

    • Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!
    • And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.
    • I have an R32 Fenix rad. It is good.
    • All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents   
    • Been a busy but productive day. Axle and hubs acquired. All fitted up after a bit of modifying. Need to sort out wider mudguards and running light reflector covers but other than that the trailer is gooood to go !!
