Hey guys...

I know a bit about my car atm but im still learning as I dont know what I am looking for in cam gears..

All I know is I want some HKS one cos they look tops lol...

anywayz can someone give me the basic lo down on cam gears ie. what I will gain and what specs to look for...

my end goal is to have my car safely running 240 - 300 rwkw...

Also I read a big load of bitching about whether you need 2 for rb25det...

Have you been in a car with that sort of power before?

Im not trying to be smart or anything but i found myself chasing numbers as well. I got to 230kw but now have it backed off to 190kw and its more than enough for me :happy:

Some people have found a gain, some have not, and some have gone backwards

So take each case as it comes.

IMO - There is nothing to be gained from cam gears on the RB25 with stock cams

I ran my car with a stock head over 300rwkw with response/power as good as people with cams/cam gears and whatever other fruit you can think of.

So take it as you will

I also doubt you will get any value out of a cam pulley without an aftermarket ecu/pfc.

You can throw $$$$ at it and it likely won't do squat unless you can tune for it, and for that you need a pfc/haltech/wolf etc.

I thought it was well known that there was gains to be had from an exhaust cam gear on R33's stock cams, aftermarket ecu or not. You retard it up to 4 degrees.

Generally cam gears can be used to change the characteristics of the power. Ie you can swap some top end for earlier boosting and more mid range power. It's up to you, the tuner and the gains/losses involved whether this is worthwhile for you.

I have 260 odd rwkw and I think I would be happy with another 100rwkw but then again I said that about 250rwkw when I was at 190.

As for specs, they all do the same thing. Get a cheap one I say.

i mean 150 bucks for a cam gear! its cheap enough to throw it on... ill get back to you if it makes a difference :-P

Yeah, they are cheap :stupid:

But i've seen a few loose power and some get nothing out of it.

And then i was ok.

Each to thier own, by all means give it a shot dude :)

As you said, they arent expensive. Just the tuning time.

Also - just get your stock ones modified to become adjustable. Might not look "flash" but work the same way and half the price of HKS items

Or just go in for the group buy thats happening at the moment.

$140 a pair. Cheap as.

Yeah i was just going to suggest that too! I cant see how $230 each for a HKS gear is justifyable. Like they look good and all but geez.

Go for the group buy, theyre at 140 a pair now, u cant go wrong with that.

    • I'm hoping I just don't have to do an engine rebuild NOW. Doesn't mean I won't do it at some point. I think a plus point is that the car presumably ran on or close to stock power nearly all it's life so far. Only the Owner I bought it from actually increased power with a standalone ECU and blew the OEM turbos. And after it got thee 2860s it wasn't driven an awful lot either.   That is what I meant. With the twins coming on so late (4500-5000rpm) I hope the rods won't want to exit the block prematurely. And it still being a 26 means the torque curve isn't gonna hike up all that much.   It didn't blow up on the dyno when they tuned it to 500ish crank. So I suppose it'll be okay for now. They did put a Tomei head gasket on first though which did not seal at all, and they redid it with a Cometic one. Which I hope won't be my water leak.   Mainly anything oil. So far all it has is the N1 pump, oil restrictor and a filter relocation kit with a cooler.
    • 15000? ish? Something like that anyway. It wasn;t so much a wear as a tear that then spread. Might have lasted a lot longer if not bothered by just one incident, whatever it was. I took a punt. They are really comfortable and do a good job of holding. My daughter HATED it when I first put them in, and probably still does now. She has sensory issues and hates the way they are all up your business. I'm 197cm and 95kg. Not fat or particularly wide, and the XL size seat is the rigth fit. If I was any fatter it would start to get too snug. Any skinnier and you'd possibly want the smaller width.
    • Mrs rs focus came factory with recaro cs  sportsters in it and they a pain in the ass to get in and out of with the really high bolsters, once you were in them they were one of the most comfortable seats I have ever sat in
    • The NA 2.5 has very little torque. You won't feel much. Those trannies are also a million years old now and it could well be f**ked. First generation electronically controlled autos will often refuse to kick down, ete, etc, depending on what's wrong with them.
    • Yes, but no but yes but no. Those "it's fine up to 500HP" rules and everything else like it were all determined back when the cars were 10 years old. As they are now 30 years old.....what do you reckon the chances of something shitting the bed are? I'd say they are much higher now than they used to be. You might be lucky. You might be unlucky. Spin the wheel and find out. Yeah, nah. It's actually exactly the opposite. Making boost early and having heaps of torque able to be generated right in the middle of the rev range will do more to damage an engine than having to rev it high to make the power. Think about the load on the conrods, bearings, etc, to make 400HP at 4000 rpm, vs 400 HP at 6500 rpm. So someone has already "let the Nissan out" which is how we describe the increased chance of a fiddled with engine to have had something done wrongly. Many more engines that have been opened die than stock ones do - even if you into consideration how they are treated wrt power levels and the like. Again, not saying that yours will definitely have been put back together by a moron. But the possibility does exist. It's still a lottery. Spin the wheel. What weakspots?
