Aftermarket Cams

Mattyb thanks but i have a RB20DET, so that isnt applicable to me.

A pair of cams + slide pulley gears is not too expensive.

Maybe $900 for the cams, $350 for the gears.

You can even keep your NVCS VCT with the Tomei set (not sure about HKS).

However for your $1,250 (say $1,500 to install)...

It is giving you $1,500 worth of power?

I suspect not.

how much would it cost to get a second hand rb20de exhaust cam, and would any other parts be needed to get that onto an rb20det?

Spose its a matter of what you consider value for money. Some people think nothing of spending $200+ in a night out. God knows my best effore was over $1k (bloody kings cross:D)

I certainly think my cams and cam gear are good value for money - I will get to enjoy them every time I drive the car - once they are in.

They cost a bit more than the figure you quoted above too.

INASNT - We can do any camshaft. We are the only camshaft manufacturers in Australia. Our facilities are the most impressive in Australia (Cause they're new and neat). And from a true engineering point of view - Yes ours are the best quality. TRUE ground finish, with an ultra-light series of cams on the market too. I have a bachelor of Mechanical Engineering and the boss (Dean Tighe) has an A.D. in Mechanical Engineering. Ivan Tighe makes valves now and co-designed the Repco/Brabham F1 V8, AND he still races his BDA powered open wheeled Kadicha Hill Climb race car. The thing is nuts - and he's 73!!

Crane Cams is American. Sorry about the blurb.

OK READY? In a bucket actuation such as the RB series motors, the camshafts need to be made from Iron. Problem is, you can't make Iron billet camshafts in the RBs length and diameter (Too slender- hard to machine) The way around this is we can make billets from our steel, then the buckets would need to be chrome plated and journals and lobes would need oil holes drilled. JEEBUS they look good but. Doing some 7MGTEs for Toyota in Canada, same style of cam and they look sweeeet.

Cost - Not sure call Dean

Or we can do what we do to almost every other set of RB cams (including mine) and build them up then grind them down, which does not require lash caps or spacing as the base circle is kept intact. Cost for this is $1200. Now don't go nuts cause there is HEAPS involved. If you saw how long it takes to set up, then grind, then build up, then grind and repeat and crack test and straighten, you'd shit yourself.

Call anyway and ask.  (07) 3271 6001

I take it the $1200 is for both cams.... right?? Also can you guys supply heavier valve springs? also at what price?

Sorry about all the questions..

Cheers,

has anyone had any experience installing a NA RB25 cam Into a DET?? And real info would be good.

[Steve]

BOOSTD, I was under the impression that JMS did this with their red R33 earlier on in the piece, not sure if they still run it that way, but might be worth asking?

I jus got a set of Tomei Poncams installed 256 duration and 8.5mm lift. And agree with Steve think is money well spent everytime i drive the car sounds mean 2:)

did u get for both intake and exhaust??

[BOOSTD]

Steve; I asked JMS that a while ago and they looked at me like I was daft. Said that rumour has no weight.

[T0nyGTSt]

How do you determine what lift, duration you need?

To be honest, the money is not the problem.

The price for a pair of cams + gears is not bad. And what 'Stage' do you need?

If they improve the response and 'feel' of the car, why not?

[Steve]

BOOSTD, looks like its time to dig up the old copy of SPEED, in which the car was featured. 90% sure they stated JMS used NA cams?

[lukevl]

JNR24- $1200 is for both cams. Remember, this is to build the camshafts up and grind them away. This keeps your base circle the same and negates the need for spacing the buckets.

If you think $1200 is too expensive, we can supply you with larger cams than the Tomei ones mentioned for $400. more duration and more lift. There are many options.

$350 for adj. cam gears. You can keep your VVT or shaft it. Up to you.

Yes we can provide stiffer springs - Iskenderian Racing. That is what I'm doing. Bit of mucking around but worth it. The springs themselves cost about $450.

Also Titanium retainers - $45 each. or $20 each for Chromoly.

TonyGts-t : Have you experienced our $1500 worth of performance? No? Well do your research on our product before heading overseas.

lukevl,

so if i sent you my camshafts it would cost me $1200 to get them done, i would be getting them done to get more bottom end and get the turbo boosting earlier? would your cams do this? Also if i had them done would it be a straight fit or would the head need modifying?

Thanx

Evan

[lukevl]

$1200 will get your cams built up and they will bolt back in to your engine without having to use lash caps or tipping your valves.

From what you are saying, we might be able to grind you cams down. This will cost $400 and will require spacing of the buckets. Like I said, we could grind a profile onto your standard cams bigger than the Tomei one mentioned earlier.

Also if you go for big-ish cams, like mine, you will need to relieve the cylinder head so the lobes don't foul the casting. No biggie.

BOOSTD, page 50 and 51 of issue 3 of Speed state that the JMS R33 has Tomei 264 exhaust and RB25DE inlet cams.

[BOOSTD]

I`ll ask Terry again when I see him.

[ILleN]

INASNT: Sorry bout latenes in reply yeah both intake and exhaust.
