HKS Adjustable Cam Gears

[ph1]

I've got a shipment of parts leaving Japan this week, i may have some room left in my boxes so if anyone wants some cam gears to suit rb motors let me know.

price around $230ea so $460 the pair.

[two40]

Is this the adjustable cam gears or stock ones?

[ph1]

as it says in the topic

[two40]

Haha ha. I just saw it after I posted. What a dildo!

I'll let you know tomorrow night if that's not too late.

[Squizz]

what sort of gain do they give?

[two40]

Roughly 10rwkw. It all depends.

ph1 - I want a set. check your pm

[ph1]

golden week in japan has f**ked everything up, hks orders are minimum 1+ month wait at the moment so they wont be delivered in time for this shipment, sorry dude.

[two40]

No problem. Thanks all the same, maybe next time.

Even though you guys missed out on getting the gears, one small point to remember!

You can ONLY do the exhaust cam gear on the RB25DET due to the VVT on the inlet cam gear. It "MAY" be possible to modify or adapt the stock inlet gear or even the HKS one but it would be a bugga' to do it & not worth the cost for such a small gain ( around ~5rwkw max even on a full bolt on upgraded turbos etc... RB26DETT motor).

I gained roughly 10rwkw (so far) from doing the ext' gear (via 4' retard), I say so far as ECU issues caused problems @ dyno testing was unable to be completed

For anyone thinking of doing this mod I suggest waiting until you have a way of over coming the stock ECU's timing retard (the cause of the dreaded RB25DET flatspot) the adj' ext' gear only makes this problem much much worse :x you gain power but you get a very poor power curve (& the car will drive poorly).

Sorry to hijack the thread people, thought this info might help but.

Thanks for the heads up. Ethan 33 told me this just as I was going to order some from a local dealer.

Mot all 33's come out with VVT did they? The reason I ask is that my mechanic asked me what year my 33 was. He said that the late models have them but not the older ones. Weird.

No prob's mate.

My GTS25t is a late '94 model & it's has VVT.

If you look @ the black t'belt/cam gear cover front on (ie standing @ the front of the car looking into the eng' bay) one side has the alloy crank angle sensor (exhaust cam gear) the other side has a bulge (inlet gear) the bulge is to clear the VVT gear. Just back from the inlet gear on the side of the eng' is a long housing with an elec connector on it, this it the VVT solenoid. The VVT is there to improve bottom end power NOT top end!!! (So I'm lead to believe!?!?!)

I'll see if I can dig up a pic with arrows pointing to the bits in ?

[two40]

I'll check it out. Pics would be cool.

hi ive got a 1993 and its got vvt maybe hes talking about the r32

[ricknismo]

so any info on GTR gains

[RNGTR]

ricknismo, mine went from 226rwkw to 237rwkw. So its a worthwhile gain.

[ricknismo]

Is that with an after market computer?

[ricknismo]

what other mods do you have?

[RB GUN]

bump...

[phorj]

My old man had 159.5 on his R33 GTR.

Put on pfc, HKS cam-gears, Apexi filter in std air-box and an Apexi N1 exhaust.

with tune it's now good for 199.8kw at all 4.

still running stock boost, etc.

[DAHXX]

Mine went from 170 to 200 kw.
