Best place to source mild cams for the RB25det quickly and cheaply

[rev210]

I may require a mild cam shaft set for the engine rebuild.

Any ideas for a brand and quick supply.

The intake cam needs VCT, for a stock ecu.

[Steve]

Greenline are probably the cheapest I have seen - not sure on availability, best e-mail and ask them I suppose.

HKS cams are suitable with NVCS

[Sydneykid]

We use Tomei

[rev210]

sydneykid ,

Also what part No. for the Tomei unit's dude?

Hi Octane Racing in Rydalmere do Tomei.

Sorry guys, so many questions..........

GT1 first , http://www.hioctaneracing.com.au/

We use them (as Performance Metalcraft) for fabrication when our team fabricator is too busy or away. They do top work.

Rev210, they have Tomei camshafts in stock. Sorry my cattledog is at work.

Inasnt, yep the Tomei Poncams are designed to work with VVT. Don't bother with an adjustable exhaust pulley they are pretty much spot on standard, spend the money on something else.

Hope I answered everbody

Sydneykid thanks for the info.

What's the mildest grinds availible for the tomei Poncams?

[B-Man]

Rev - I think this is the mildest:

Tomei Cams 256 duration and 8.5mm lift compared to standard 240and 7.8mm lift

That's what I am putting in my car during re-build

[rev210]

B-Man,

What was the $ damage for a set of those?

These still use the standard hydro' lifters?

[B-Man]

YEs, I understand they work with the std hydro lifters - I'm not changing mine anyways - Unless the head people do that without me knowing about it.

Price - Well, I think I'm paying a bit more than normal - but I'm also getting a package deal and make up for it on other things - So you should be able to get better then $1200-1300 - Cheaper if you import yourself (But not quicker) you pay a premium for off the shelf stock on Oz......

Whats the high duration and lift you can go without having to do head work? 270 duration?

And with a high duration and lift say 270 what will the idle be like in traffic?

[Sydneykid]

Hi INASNT, if you mean "headwork" as in clearancing to fit the camshafts (not porting) then duration is basically irrelevant, lift is the issue. When we get the lift over 9 mm, we die grind the head to clear the lobes. Pretty simple, you can do it in the car as long as you clean up properly afterwards.

So to answer your question we have run 292 @ 9 mm without "headwork". We also have run 264 @ 10.5 mm and done headwork.

To answer the second question, based on my personal experience;

240 is standard GTST

248 is standard GTR

256 is a good mild street upgrade, go for 9 mm lift

264 is a good combo (street, track, circuit) go for 10 mm lift

272 is a good for circuit work at 10.5 mm lift

Anything more than that requires a big turbo/turbos to use it, to get the best a close ratio gearset or an auto would be my suggestion.

There are plenty of people running around with more than the above, but they don't seem to keep the car very long. They get there jollies from the doing (or the bragging) rather than the driving.

Hope that helps

[Guest INASNT]

Sweet thanks for the info.

[GTS-t VSPEC]

Rev210, Seeing as your selling the car, get the insruance company to pay for the cams, then I'll swap you for my stockers, plus I'll be your friend:D

Hey guys

does anyone know how a HKS step 1 (I think they're 256 whoops I meant 264) exhaust camshafts would go with the standard inlet Camshaft?

being step1 I heard they're ok for on the street, but would they work with standard inlet cams?

Also any ideas where I could get the stock exhaust Cams?

Im having no luck here in WA

[Steve]

HKS step one for exhaust is 264 duration, 9.0mm lift.

[Sydneykid]

I'm confused, I have seen 256, 260 and 264 described as "Step 1". Plus I have 264 described as "Step 2". So I just call them 256, 260 or 264, "Step" is a useless term.
