K Series TRD Camshaft In English

 

Try that.

Will be A LOT of work to fit a TRD cam shaft:

 

Stock cam on left TRD cam on right. Notice the bearings for a TRD cam are HUGE and the lobes are longer. Will need to bore out bearing area of cam and fit larger bearings if you get that cam.

 

Or just get a stock cam regrind it to what suits your car and done..lol Much cheaper.

Looks like that trd cam would also need matching gears and chain to suit aswell,

 

cheers phatke30!

[camerondownunder88]

You got a good eye phatke30

 

The TRD cam doesn't use a chain.

 

They use solid gears like Holden motors. small bracket with bearing holds gear bolts onto block and new crank adn cam gear fitted.

Like this picture shows..

 

For what it is worth, You would be better off getting a standard cam reground to spec as we have better technology these days when it comes to cam profiling..

What with that centre gear MM???? is that a TRD item or something? Or is that very much custom?

[Sam_Q]

damn that would be a noisey setup!

 

I know some people would be horried by the sujestion but in concept couldnt you give the cam to a lathe grinder and take the bearing size down to stock?

 

why do you think they did it anyway? to reduce head wear?

[camerondownunder88]

TRD gear drive system is an off the shelf can buy option Taz that isn't custom.

 

Also TRD 3K I believe can bounce around the 10,000 to 11,000 RPM mark. At 11,000 RPM cam is doing 5500 RPM stock cam only should go to 3150 RPM so I guess they run bigger bearings to help with load more oil film around it and surface area for oil to work on. And the trust face is bigger so I dare say the gear system put extra axial load on the cam shaft.

 

You could grind it down to size no worries. But I think with a reground cam you can get a way better cam profile and keep the TRD one for a collectors item hang on the wall..lol

 

Also the TRD 3K had 150 HP and bigger valve springs so I would also hint the extra valve spring load might of made them run bigger bearings.

[Medicine_Man]

Yes that there is the genuine TRD 3K gear..

[Philbo]

The centre gear would allow the cam gear to rotate in the correct direction. It spins the same way as the crank gear. (Imagine the chain drive)
