is this enough info for a cam to be reground to specs?

 

 

no, it isn't. all it tells you is at what time certain events occur, or what the max value of those events is.

ie. valves leave the seat at x degrees, valves return to seat at y degrees, and at z degrees max lift q is achieved, etc

but what about the shape of the profile? the ramp rates, etc. you need a scan of a pair of physical camshafts to duplicate them.

I wander how much different a 4k TRD engine manual would be.

4 gears are used to drive the cam shaft on a TRD motor. 2 idlers 1 one cam 1 on crank. Was the weak point they actually had issues with them breaking.

 

Also TRD used 2 types of oil coolers a belt driven pump or one that bolted to the front of the cam shaft and came out the timing chain cover and was a pump. Also the oil cooler can be complimented by the TRD dry sump was one for sale in NZ just a few weeks back for a pretty penny :yes:

 

Also 4K TRD motor hand book like this 3K one doesn't really exist. But get a copy of the TRD parts catalog and it list 3K TRd and 4K TRD parts. Motor again is same the TRD 4K parts stage 1,2,3. never really existed only done for 4K. My TRD parts catalog only list 3K but a lot fits 4k,5k, etc.

shit that's rediculous

4 gears, so the cam runs in reverse to the usual direction, thus all the ramp profiles are different?

No

This is what a gear drive looks like

The cam still runs in the same direction.

When its in good condition the drive to the cam is positive no slack etc like what you get with a belt/chain. But the wear rate can be a little high, unless Teflon coated gears are used but then you miss out on the whine from the gears....

Yeh I wasn't sure if it was 2 idlers like that or in sequence. the wear rate should be lower with the 2 idlers instead of one because they share the load.

lol DAMN, I just payed almost 20 USD to buy this from american ebay and have it delivered haha

And there is a good chance it has a page missing.

I was tempted once to buy the ebay one...

 

But then I think there just coppies from the one on the net so held off...Let us know what kinda of copy you get from ebay.

 

As I think TRD ke70 is on the money ;)

 

Cameron

Or you could buy a copy of the 4AGE Engine Diagnostics manual that has my handwriting on the pin-outs page.

 

That's also available for a price on US ebay.....

 

The stupid prick even had my forum name in the title, as that was what it was called when he lifted it of the site that hosted it for free.

Does anyone know where I may be able to get a copy of the old Tosco tuning manual?... the link here is no longer working

I am wanting to build up a full race 3K and would at least like to have a read of the manual as a starting point

Thank you

No idea for above, but if you can get a part number take it to toyota and you should be able to get it, for $$$ though :)
