Guest dnm Posted November 1, 2008 Share Posted November 1, 2008 came accross a site that offered a timing gear set rather then the stock chain, but have since been unable to find again. does anyone have info for such a manufacturer/retailer? and pros/cons to such a conversion? I have a basically stock '81 280ZX i found for a fantastic price and as i learn more about the line i am really falling in love with em. but i would like to build up the engine soon and from what i know of american muscle cars gears can be much more precise. any and all info/perspectives greatly appreciated.

Smokescreen Posted November 1, 2008 Share Posted November 1, 2008 I would be interested as well. I also come from more of a muscle car back ground and have wondered why there aren't any timimg gear set ups for the L28's. Now to hear that somebody offers one I would like to hear if it has been tried and blah,blah,blah:wink: Quote Link to comment Share on other sites More sharing options...
Guest dnm Posted November 1, 2008 Share Posted November 1, 2008 smokescrren was jus lookin at your post lol. hella nice job. i paid 600 for mine but it sat in the vegas sun for 6 yr.s. it was towed home on a flat trailer but with a fuel pump replacement she fired right up and ran like a banshee. that was 3 mo.s ago now and have since been doin basic engine upkeep mostly as well as reading everything i come across about the Z line. should i happ across the sight again you'll be first on my list to send to. 5 biker uncles tought me all about american muscle never dreamed i'd be interested in a foriegn model.

Dragonfly Posted November 1, 2008 Share Posted November 1, 2008 Disclaimer: I am going on hearsay and what I have read with the following comment... so please prove me wrong. From what I understand there are no "timing gear sets" for the L series engines and the reason is because of the distance between the crank shaft and the cam shaft, this distance is much greater than in a V8 and does not have the width needed to place the idler gears required for a gear set. Now this I know: There is an idler gear set that can be purchased for the L series engines that replaces the tensioner shoe with an idler gear and the plastic/metal giudes with idler gears, this system requires manualy setting the timing chain tension and therefore frequent testing and resetting but it reduces (to a small degree) parasitic drag in the engine and it allows more accurate timing with a higher red line when used in conjunction with upgraded ignition etc. etc. In a nut shell what I am saying is that if your engine is not built to an extreame degree (balanced, blue printed and full of forged parts $$$) this idler gear set is nothing more than a "cool" part that requires extra maintenance and attention.

Smokescreen Posted November 1, 2008 Share Posted November 1, 2008 The dynamics of the L series and how they interfere with the timing gear set up make sense and as for me, I am running nothing but stock so fancy "cool" parts are not for me:). Thanks for the clarification Dragonfly. Yeah DNM, I totally got a suprise when this car fired up. Obviously 170k ain't nuthin to a Z!! I came from muscle but I sold it all when gas prices went astronomical.... Now I own a true coupe, no back seat and plenty of potential.
