DatsunBoy77 Posted April 7, 2004 Share Posted April 7, 2004 Yeah, when i meant cheap i meant less that 550. Probably still up there just around that price, because i am sure trying to get a group to buy them through whoever their distributor was would be very difficult. Also, i know it is wrong to copy it but it something you just have to ask. Maybe change some of it to where there could be something it could use to better their design, if that is possible.

HS30-H Posted April 7, 2004 Share Posted April 7, 2004 They claim that the part is safe up to an estimated 13,000 rpm without failure, based on calculation rather than practical experimentation. They have never suggested that an L-series 6 will ever rev anywhere near that. Quote Link to comment Share on other sites More sharing options...
rc's240z Posted April 7, 2004 Share Posted April 7, 2004 HS-30H is it possible to get one of these through your connection? Quote Link to comment Share on other sites More sharing options...

HS30-H Posted April 9, 2004 Share Posted April 9, 2004 Pics of installed setup: http://alansphotos.fotopic.net/p3712799.html http://alansphotos.fotopic.net/p3712800.html http://alansphotos.fotopic.net/p3712823.html Notes: Stock ( mechanical ) fuel pump cannot be used if the KAMEARI Twin Idler tensioner is installed Some fettling of the head casting may be necessary - especially around the inside radius of the timing chain inspection cover recess and fuel pump mounting recess. Each individual head will be different in this respect........ Quote Link to comment Share on other sites More sharing options...
fl327 Posted April 9, 2004 Share Posted April 9, 2004 This might be the dumbest question but it makes me curious though. Does this twin idler pulley (impressive piece i must say) let you pull of the head without hanging up the timing chain on a block of wood? It looks like you could tension the chain up by pushing the allen heads out so that a head gasket job could go by that much quicker? Quote Link to comment Share on other sites More sharing options...
HS30-H Posted April 9, 2004 Share Posted April 9, 2004 The adjustable part of the tensioner is attached to the head, as you can see. If you are taking the head off, then you can't adjust the tensioner to hold the chain tight. So the short answer is 'no'. In my opinion, this could go two ways. If you want to take the cylinder head off the block, you either go the whole hog and take off the front cover and sump ( or at least loosen the sump bolts ) or you take great care to hold the timing chain and not let it slip off the crank gear. There's no spring-loaded plunger anymore, as its replaced with a free-rolling gear. That gives nothing to push down against with your block of wood or purpose-made chain tensioner tool. However, it also means that there's no plunger trying to pop out of its housing and push the chain with it...... I'm sure it would be possible to pull the head and not let the chain slip, but honestly speaking I think its more difficult with the Kameari setup - and I'd rather pull the front cover and do it properly. Of course, that's only my opinion. In the normal run of events, I don't usually plan to be pulling heads off all that often......... Quote Link to comment Share on other sites More sharing options...
fl327 Posted April 9, 2004 Share Posted April 9, 2004 I respect your opinion, trying to do things official is a good thing. That piece looks great and im sure it will give the owner of such an item great satisfaction knowing theres one less thing to go wrong. Ill live with my rubber guides and do my headgaskets the way Nissan tells me, with a block of tapered wood and a clothes hanger Quote Link to comment Share on other sites More sharing options...
HS30-H Posted April 9, 2004 Share Posted April 9, 2004 I don't think I spotted the clothes hanger amongst Nissan's official tools I don't see any problem with using the standard Nissan chain tensioner system, and Kameari themselves still sell the standard Nissan parts for even very high powered engines. Nevertheless, they found that chain-whip caused problems with cam timing ( and even some related engine failures where valves touched pistons ) in very extreme situations. This is why they developed their new tensioner. Its NOT meant to be a 'bling-bling' part, and I really hope that everybody understands this.

Lockjaw Posted April 12, 2004 Author Share Posted April 12, 2004 Actually, once I install it, I should be able to answer the question of removing the head while leaving the chain it. I was thinking perhaps you could actually do that. The parts are beautiful too. Its hard to not appreciate the workmaship and quality that went into the manufacture of them. Plus you know, the few of us that have them, well we are exclusive. I also saw the benefit of the set-up was controlling the chain for these higher output turbo engines. Mine goes from off boost to on, and into the rev limiter in first gear very quickly, this pulley set-up should really help there. I suspect it would help more for people making more power then me too. I would also expect them to vigorously persue anyone copying their design. Its obvious from looking at the pieces that it is a very well thought out and engineered kit. When I say it looks to good to put in an engine, you have to appreciate the quality of design that makes it up. Its awesome looking. To bad it doesn't sit outside where someone can see it.
