-31 actuators
Can someone explain to me why i would need one and would my car benefit from having one ?? Ive got a standard turbo as far as im aware , chipped ecu , piper cam , airtec frount mount intercooler , full mongoose ! At this spec do you reckon id need one ?? Oh and who does the best one ??
Thanks in advance http://www.seriesoneturbo.co.uk/imag..._thumright.gif |
I believe the -31 has a lift pressure of about 8psi without pre load and a -34 has lift pressure of 14psi.
They operate using a spring which over time will weaken and not hold the boost pressure leading to a drop in performance. You will probably be replacing like for like with a -31. I would use the Garratt version supplied, amongst others, by msd. |

Just had a look. This would be fine. I think you can get some discount off that if you read the ads on the site banners for msd. |
yeah as said above, a -31 is a Cosworth actuator and is slightly stronger and will hold boost better under load.

Thanks for the replies fellas , very helpful !
Its not that ive been advised to get one , its that im restoring the engine bay and engine ! As im going to be stripping down the turbo and repainting both the turbo and manifold , i noticed that the actuator looked a bit buggered so thought if i was to replace it i might aswell go for a modified one like the -31 ! Good plan ??? |

Its not that ive been advised to get one by anyone . Its that im restoring the engine bay , including engine and box and ancillaries . As im going to be doing the turbo while the engine is out i noticed that the actuator looked buggered ! So i thought if i was to replace it i might aswell go for a modified one like the -31 . Good plan ???? |
Little bit of advice. There isn't a paint on the planet that will whithstand the heat of a turbo. Any paint you put of WILL flake off within a week. Ceramic coating or heatwrap is the only effective cover.
other than that yeah, a -31 actuator is a straight swap and doesn't have any adverse effects, just positives which is quite rare for a modification :lol: |
