SeptemberSquall Posted September 26, 2008 Report Posted September 26, 2008 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.

Rolliac Posted September 26, 2008 Report Posted September 26, 2008 I wander how much different a 4k TRD engine manual would be. Quote
camerondownunder88 Posted September 27, 2008 Report Posted September 27, 2008 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. Quote
OniBerserker Posted September 27, 2008 Author Report Posted September 27, 2008 get a copy of the TRD parts catalog[/url]hey cam where can i find a copy? Quote
Gavatron Posted September 27, 2008 Report Posted September 27, 2008 That first cam is pretty large. All of them are but the first one is wild. 53 91 87 55 Overlap of 108 degrees Inlet Duration 324 Exhaust Duration 322 Quote

philbey Posted September 29, 2008 Report Posted September 29, 2008 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. 4 gears, so the cam runs in reverse to the usual direction, thus all the ramp profiles are different? Quote
towe001 Posted September 29, 2008 Report Posted September 29, 2008 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.... Quote
philbey Posted October 6, 2008 Report Posted October 6, 2008 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. Quote
7FOUR7 Posted November 5, 2010 Report Posted November 5, 2010 lol DAMN, I just payed almost 20 USD to buy this from american ebay and have it delivered haha Quote
TRD ke70 Posted November 5, 2010 Report Posted November 5, 2010 And there is a good chance it has a page missing. Quote
camerondownunder88 Posted November 5, 2010 Report Posted November 5, 2010 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 Quote
parrot Posted November 5, 2010 Report Posted November 5, 2010 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. Quote
farrell3k Posted March 13, 2012 Report Posted March 13, 2012 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 Quote
19914afc Posted March 13, 2012 Report Posted March 13, 2012 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 :) Quote
