Roller Rockers or Extractors

I have been given the green light to spend my tax cheque on the car. It is not a huge amount so I am looking at 3 options:

1. Yella Terra 1.72 ratio Roller Rockers (ST2027) at around $510 plus fitting
2. Pacemaker extractors @ $850 including fitting
3. Advance headers @ $850 including fitting.

I am leaning towards the Roller Rockers at this stage, but is it worth getting them before I get an exhaust - remembering that I can only get one or the other at the moment, so I need to go for which one will give me more punch now. The car has a 3" cats back system already, and has good pickup from about 2500/3000 rpm - I'm hoping the RRs will give it a bit more down low.

Am I on the right track, or should I get the extractors first, so that the RRs make a bigger difference when i eventually fit them (next year?). Help! Anybody fitted the RRs at all? Did you fit them before any exhaust work? Did they make a noticeable difference?

Re: Roller Rockers or Extractors

hi JC..
Im pretty sure everyone will agree that, the exhaust system will give you heaps more gain than the roller rockers!! But as I found i lost abit of lower down torque, it was rather un-nerving, but once the car was chipped the difference was huge.
The difference in power form the valve lift, to extractors will be quiet minor im sorry my friend.

Re: Roller Rockers or Extractors

Yeah go the extractors first. BTW, the advance headers are only $390 to buy off the shelf, $460 to install is way too much. Even with the pacemakers you are paying around $200 installation which is still too much IMO but closer to what I would expect.

Re: Roller Rockers or Extractors

i agree pipes first... but after seeming those prices EDXR8 quoted,

If you turn up with your headers under arm, couldnt be more than $100-$150 to fit?

Ignition got his paccies supplied and fitted locally up here for around the $650 mark afaik

Re: Roller Rockers or Extractors

Thanks guys - as usual, I got impulsive, so RRs are on the way - also the $350 saving on the price of extractors will go towards the extractors - just need to add to it until I get enough. Also, might get the extractors done at the dyno day if i can convince her indoors! I am also looking at other options for extractors - perhaps some second hand HM headers (bluedriver??).

I agree the fitting charge is a bit steep, but each place I've talked to says it is between 3 and 4 hours labour, so $200 is about right.

Now, anyone know how to fit RRs????

Re: Roller Rockers or Extractors

Roller rockers are a waste of money. Get the exhaust!

Re: Roller Rockers or Extractors

strip the upper manifold off, flick the ignition leads outa the way, remove your sexy rocker covers and then just TDC and remove and replace with your new RR's


We actually fitted the FMS rockers but no doubt the process is the same
