Demarosso New Member 4 Member For: 1y 5m 20d Gender: Male Location: Melbourne, Victoria Posted 14/02/23 08:00 AM Share Posted 14/02/23 08:00 AM Hey guys, I have have bought a BF gas + turbo motor a while ago, and the seller claimed that it has performance valve springs (Crows Cams) and some other goodies in it. It also came with a turbo exhaust manifold, turbo, external wastegate, intake plenum, etc. so seemed legit and I didn't check what's inside. Now I have finally opened the valve cover and did not find the promissed plazmaman head studs 😱, so I suspect valve springs may also be stock... 😱 Could you please suggest a way to identify if my springs are stock or indeed performance...?

I've found carnts will start telling the truth after they wake up from being knocked out and you start breaking their knees. It's not for everyone but it works 1 Link to comment Share on other sites More sharing options...

I am considering taking a spring from this engine and another spring from a spare engine. Then compare them, I.e. strength, height, etc. I suspect aftermarket ones would be stiffer and maybe a bit taller. Maybe that could work... 🤔 On 14/02/2023 at 9:10 PM, Puffwagon said: Ask the previous owner.

You will be able to push a stock spring down with your fingers somewhat easily depending on how strong you are, you won't be able to budge an aftermarket spring unless you're a maniac. 1 Link to comment Share on other sites More sharing options...

There is visual difference. I have now installed Dominator Motorsports 95 lbs springs. Edited 28/07/23 10:28 AM by Demarosso Link to comment Share on other sites More sharing options...

I purchased an FG XR6 Turbo last year. It's been tuned by a pretty reputable aftermarket tuner within the scene but they didn't list that valve springs were changed. Turbo, injectors, intercooler and a tune were all done. I'm guessing they were but can't tell for sure obviously. I haven't pulled off the valve cover yet, no need to as the car is running well.
