Hi Guys, I am putting in braided lines to replace the vacuum lines but -4an is too big and $50 a meter, and -3an is too small but $16 a meter. so I have bought the -3 hose and some fittings from enzed to match but am worried about the internal differences in the hoses refer to pic. can anyone let me no of any problems I will run into with this set up? will it give improper boost readings/control reducing internal diameters?
Don't know much about it but I would expect a smaller diameter to be more responsive. Assuming it is not past the point of being restrictive anyway. Perhaps some pressure build up in some cases probably not here. ???
-3AN should be fine. You doing it properly with threaded adaptors for the BOV's and weld on joints for the wastegates and all that? Not much point doing it without it, just use sheaths over silicone if you only want it to protect from heat/rubbing. If you want to deck the engine out in braided lines then don't baulk at the cost, it will add up very quickly if you do it properly with the correct ends and all that.
