-18 actuator is there such a thing???? i won an actuator on ebay which was said to be a -31 for £16 now the guy is NOW saying that it's not a -31 but a -18 anyone know if you can get a -18 or is he just bullshiting me . He said these where the numbers on it 95-130 H1 29 430099-18 which mean nothing to me anyone on here know if it is a -31 or a -18 if it is an -18 whats the differance and are they anygood he said that it came off a stage 3 cossie.

 

Not sure about a -18 but I've got at home a -38, -62 & a some other obsure one!!!!

 

If the sale falls through I have a brand new in the box -31 you can have for £50. I know it is more than the above one but I know it is right as it was bought from Woodford

I had a -18 on my 3dr when i bought it. Looks identical to a -31 too. HAd no problems running 28psi through it but the lowest we could get it to run was 18psi

I have it sitting in my garage as I changed it when I changed the turbo.

 

-18 will be no good for the rs then don't want to run that much boost on a nearly standard engine

 

a -18 is a standard 2 wd cosworth actuator and is around 6 psi

 

oh well it's not a -31 what i bidded on so he can keep it cheers for the help guys

 

Tony - do u have any idea why we could not run it lower. Car was a stage 3 at the time, with hi/lo boost switch, we also wound the actuator all the way and 18psi is the lowest we could get

 

r4 nss have you still got the problem

 

RAN, possibly the amal valve jetting?
