Been doing a lot of research on shocks and boost.The shocks I think is sorted I will talk about that later.Anyhow since owning my forester turbo and from what ive been reading book figures for the car ive seen is 170bhp and 177bhp which ever one that's surposed to be.Anyway since owning the car ive changed the turbo to a TD04 from a WRX and don't get me wrong there is a big difference but it never delivered boost like a WRX or various other models and I no it does need mapping to finish off.I have other mods fitted as well like a 3inch bell mouth decatted down pipe and decatted middle section as well.But anyway lol I was looking into restrictor pills,i have a 1.2mm one so what I did as a test was a tip from a mig welder just to see what would happen and well,the car picked up better it was an instant result but its no good because it shouldn't be there.Subarus wasn't sold with mig tips as you no lol.So the other thing I did was research Forester bov valves from lots of reading and asking it turns out the Forester bov has two vac ports for the bov for a big reason.The reason is because the Forester has such a small turbo being the TF035,if boost wasn't controlled properly the little turbo would blow the engine to pieces so what Subaru did in a round about way is put two ports on the bov so when the boost comes on aggressive the second port closest to the intercooler opens up and some how controls the boost so its delivered smoothly so you don't get the Mach 2 effect lol.What happens over time is the bottom half of the bov blocks up and then some how leaks over time so your wont be making factory boost which is goverened also by the 1.2mm pill.I bypassed this to find the fault and now its a different car altogether lol but bear in mind I have the TD04 and not a TF035.So to sort future problems ive gone for the impreza bov valve which the import people already have like Stants for example.Im gonna change my pill to 1mm as well so this will give me roughly a bar of boost.Tonight on the way home though down the motorway I had to drive off boost because there is so much there now the Fu*kin clutch slips so ive got to drive like a pensioner lol.So gonna get a new clutch and get it rolling road to check everything is bob on then get my map after christmas
