Hi Adam, It really depends on how much boost you'll be running. If you do it up so that it's only just closed then it will give you around 7psi boost with a straight signal hose and no bleed system. You should be able to move it by hand at this stage. If you plan on running 14 or more psi of boost, I would do it up just a bit further than that so that it only just can't be moved by hand and can be levered open with a screwdriver relatively easy. It is not an exact science by any means, but the tighter you go the more controlled it will be (spikes / creep) but it will result in a higher default boost setting.
DO NOT use a cardboard or paper gasket. They will burn a hole in them within around 20km of driving and you'll lose boost and things will turn to shit. Cardboard gaskets simply do not work with turbos, end of story. Get a steel gasket if possible, GCG turbos will sell you one by credit card over the phone (sometimes 2nd hand) for around $10 to $15 plus 5 bucks for an express post bag. A 2nd hand steel gasket is good enough and infinitely better than a cardboard one. You can also get a sheet of asbestos gasket paper and make one up if you wish. I have also had good success with simply slapping a heap of Maniseal goop on the 2 faces and bolting them together, provided that the wastegate flap has anough clearance without the gasket. If the 2 faces are flat and there are no clearance issues, this works incredibly well considering the cost and simplicity. Also common garden variety cork-gun silicon can be used as it does not burn. Try for a steel gasket first or just use maniseal and it'll be sweet. -----Original Message----- From: Adam Jackson [mailto:[EMAIL PROTECTED] Sent: Saturday, 10 June 2006 10:55 PM To: [email protected] Subject: actuator & gasket question I've got a new wastegate actuator for a new turbo and i'm not sure how tight the wastegate should be set? Tight as possible or simply closed? Also with re to gaskets on the exhaust manifold (sr20det) i've gone to two different places and both could only supply cardboard/paper gaskets to suit the sr20det. Would this gasket cause any problems? cheers, Adam www.sr510.com -- No virus found in this incoming message. Checked by AVG Free Edition.
