Seattle_Al Posted August 13, 2004 Share Posted August 13, 2004 Has anyone here put more aggressive cams in their Pathfinder? http://www.nismoparts.com/catalog/?section=318 http://www.jimwolftechnology.com/customer_...l.asp?PartID=26 Looks like it wouldn't be much more difficult than a timing belt job, except you have to take off the valve covers, distributer, and rocker shafts... Or am I getting in over my head... Link to comment Share on other sites More sharing options...
SnoViking Posted August 13, 2004 Share Posted August 13, 2004 I think Mr Jim did cams... but im not sure.... let me know how things go if you get them. pat Link to comment Share on other sites More sharing options...
88pathoffroad Posted August 22, 2004 Share Posted August 22, 2004 Jim hasn't done cams, no. You'll need to disassemble quite a few things to put new cams in, plus replacing all the lifters. Altogether not too horribly difficult, but not too simple either. If I had someone give me the cams, I'd do it myself, but the $400+ price tag kinda keeps me from messing with them at this point.

Come on, Mr. Moneybags, you know you want to. Any idea what the added cost of the valvetrain work, along with anything else that pops up, would bring the bottom line too? Quite a bit, I imagine.

Diesel Boy Posted August 24, 2004 Share Posted August 24, 2004 Why would you need new lifters?? (ignorance) Link to comment Share on other sites More sharing options...
88pathoffroad Posted August 24, 2004 Share Posted August 24, 2004 Why would you want to run old lifters with new cams? They suggest replacing them with the cams, in any case. Better safe than sorry. Link to comment Share on other sites More sharing options...
Seattle_Al Posted August 24, 2004 Author Share Posted August 24, 2004 After looking closer this weekend, yeah, the whole intake manifold would have to come out, too. Factory service manual lists all of the steps, but doesn't mention which gaskets need to be replaced. The JWT cams I'm guessing would be too hot for a daily driver. But the stage 2 Nissan cams (.430 lift, .262 duration) look tempting. Hmmm. $600 for the cams, plus 12 $10 lifters... (lifters should be replaced for the same reason that you should put them back in the same order if you remove them for valve work: they develop specific wear patterns for the hole they're in, and mixing them up could make them wear much faster...)

Guest bryan89 Posted August 24, 2004 Share Posted August 24, 2004 they say you need to replace the lifters, but with what? stock ones, just new. i just had my heads rebuilt because my waterpump seized up and my engine overheated, hence warping my heads. anyways, while they were in there i told them to put new lifters on it. this was less than 10,000 miles ago. would i need to replace my lifters again?

I think it may have something to do with wear patterns on the lifter and cam. Something like the lifter is supposed to rotate and the wear pattern will be circular. If you were to put this on a shiny new cam the wear pattern in the lifter may wear down the cam faster. This is all something I thought up based on one caption I recall reading in a repair manual for an S-10 so ... . But I think that if your engine is under 50,000 mi. then they don't need to be replaced. Link to comment Share on other sites More sharing options...
