Clear RB25DET Timing case

[GtstCoupe]

does anyone know if there is a clear timing car avail. for a rb25 ive herd the the rb26 fits but it is tight.

If you've removed the vct hub it will fit, if not it wont

[GtstCoupe]

what is the vct hub

[BU5TER]

that round thing that sticks out infront of the intake cam gear

You can buy an adapter plate for the RB26 cover to fit the RB25.

Have you fitted one?

how would i get an adapter

[BU5TER]

ok in the pic below notice the bulge in the cam gear cover to the left of the CAS (crank angle sensor), behind that bulge is the hub for the VCT

Now if you check the pic below of the RB26 clear cover it does not have that bulge, so adapter or no adapter it will never fit on because it does not have the space for the vct hub

i see now what a bummer

dont lose hope just yet....

might pay to drop them a line

Well that's what I was told when I called Advan - although the adapter cost nearly as much as the cover, so I didn't go ahead with it in the end. Haven't actally seen it myself though.

Try a hole saw. That will leave just a small, fairly smooth rotating part protruding.

That's the VVT actuator on the front of the inlet camshaft;

and what does this vct hub do

[GTRgeoff]

Variable cam timing (VCT) for the inlet cam, switched using oil pressure.

I'm thinking a piece of mdf with a hole in it and a heat gun and the original cover may do the job.

Use the original as the base, cut away what is not able to fit. Start with gradually heating the area you want to deform then lay it over the base. Use the mdf with the hole (or a thick wool lined set of riggers gloves) to form the clear cover over the bulge.

Basically there is nothing to see with a RB25 so why bother?

[GtstCoupe]

well if you put on funky gears and belt theres is.lol

[GTRgeoff]

As seen in SK's pic, the exhaust wheel is covered by the CAS, and the effort to put one on the inlet side is prohibitive. No-one makes one for RB25DET as it has the VCT.

i may try what gtrgeoff said

HKS make funky purple timing belts too... I reckon the clear timing cover is just as blingy as the snazzy stuff you want to show off beneath it! looks hot... dont know about 50000 k's down the track tho...
