Double row timing chain worth it?

[chargedvx6]

There is an option for a Double row chain with or without tensioner. The with option makes the chain a bees dick longer to allow some slack.

Go for one without a tensioner IMO. The tensioners are a known failure point as they shed debris over time which can block the oil pickup and starve the oil supply.

i also have a doulbe row timing chain (rollmaster) $120 trade from repco and it comes as a kit. u could possible be asking for a variable cam gear setup which i have noticed that repco can get in aswell that is around $300-$350 mark. i also been told by a number of engine builders say to be on the safe side get off my lazy ass and buy a new one tensioner from holden and shove it in. dont use your old one as due to them getting hot and cold all the time it gets very brital and breacks very easy so go buy a new tensioner from holden and doulbe row timing chain from repco or bursons and be done with it. u dont want to be pulling it apart 10,000km later as the chain has to much free play.

The Rollmaster double row chain is 9 key way adjustable. Depending on which key way you mount the crank sprocket dictates the static timing advance. These chains are around $170 delivered from VPW or Rocket. You need to supply them the part number though because there wasn't a listing for the Ecotec last time I checked

Dont get a tensioner one when running double rows. Personally id just get a new single row with tensioner. I bought i jp performce billet timing set for $90 a few months back theyre adjustable aswell

JP and Rollmaster are the same company with the same sprockets. The JP set comes with a black Rolon chain and the Rollmaster set comes with a silver JWIS chain. There have been case of the JP set failing on some more extreme builds. None for the rollmaster that I've heard of though.
