RB25 pulleys

[justified2.4]

Does anyone make lightened pulleys for the RB25, I can find them for SR20, but can't seem to find any for RB25det.

I would think Greddy/Trust would make some.

[vendetta]

i think gfb makes them...(go fast bits)

[Steve]

I have seen them for RB26, cant remeber what brand, but they have them on the greenline website.

I would love to know if they are the same for RB25.

GFBs pulleys are available for SR20s and WRXs.....haven't seen them make one for the RB25 yet...

the TRUST ones i found were only available to the RB26

[Zman]

wat kind of benefits would they give?

[justified2.4]

the benefits come from reducing the power that is taken away from the crank by accessories such as power steering, alternator, etc, since the load is lightened or the pulley is sized for optimal power the crank is not robbed of other power. Not typically a big difference, but does look good as well for dressing the engine up.

You can drop a few kilos off the weight of the pulleys if made from alloy. The under driven pulleys reduce some accessory horsepower drain and importantly reduce high rpm water pump cavitation above 7,000rpm.

Dropping as much as 4 kilo's off the front pulley rotational mass will give a gain similar to lightening the car 200kgs in the first gear. This is the same priciple for the flywheel.

The difference is large enough on a road car, good for spooling the turbo faster ,as the engine will rev quicker due to reduced inertia.

An excellent mod, overlook it if your a 'bolt on' boy, or if the engine harmonics don't agree. The RB25det ought to be fine.

I'd say the trust pulleys could be 'made' to fit.

[Zman]

wouldnt an engine be 'out of balanced' if your reducing weight from one end of the engine...

ignore this if i have no idea

[T0nyGTSt]

Engine response would be up by a big amount. With a lighten flywheel the thing would spin up like a mines r34 gt-r.

Anyone got an idea on price???

I reckon they would be piss easy to install if you do them with your timing belt.

Ring them up tomorrow. Ask when they have the bloody RB25/26

I've been offered a Greddy pulley set to suit RB25 for ~$500. So I guess that they do exist then.

[justified2.4]

For those that want pulleys for the SR, there is a company here called Unorthodox Racing, not sure if you know of them that makes pulleys for a reasonable price. I am thinking about sending them some stock RB pulleys to see if they can make alloy ones.

[Steve]

Sounds like a plan justified - please keep us informed:). Any idea how much they charge for a set?

[T0nyGTSt]

Why couldn't we make up a set locally???

Someone here must be a turner and fitter?
