abzsti Posted October 28, 2014 Share Posted October 28, 2014 Picked up my 1997 impreza sti last Friday Had a couple of things on it that hopefully some of you can shed some light on First of all the engine seems solid but overall the car looks like it has had many eBay parts fitted to it It has print outs for 331bhp, problem being I don't really know exactly what's been done to it I bought it really as I seen it as a wee project :) It has a baileys dump valve which is attached to the front mount IC piping. I have driven the car everyday since Friday, today I went to put fuel in it and I heard the DV sound. Thing went off for about 3 gear changes and now doesn't go off again. Is the DV just cheap rubbish or could there be a leak or something? It has an anti lag switch, when you switch it on it makes the exhaust sound like its just taken steriods. Backfires etc. Would any of you even use this or is it another crap mod? Has a launch control switch too, any tips on using this? Has a switch to change the car from low boost to high. I have switched it on to low for daily driving Any help would be great :) Quote Link to comment Share on other sites More sharing options...
abzsti Posted October 28, 2014 Author Share Posted October 28, 2014 Also it has a Alcatek ECU, any good? Ity has a TD05 turbo also so the last owner has just told me Quote Link to comment Share on other sites More sharing options...
Gambit Posted October 28, 2014 Share Posted October 28, 2014 To be fair sounds like you have bought yourself an amazing car :) All great mods Antilag just keeps the turbo spooled and does make it fire and pop rally cars use it but will shorten the life of the turbo. DV might have just got stuck or not had enough pressure to make it go off but I guess you was underload when it stopped so would take a look might have a leak some where. But would run bad if it did. I've never had launch control but would like it :D Quote Link to comment Share on other sites More sharing options...
Adam Posted October 28, 2014 Share Posted October 28, 2014 Personally I don't like dump valves but if you must have one then I guess Baileys is the one to go for. Someone has clearly spent a lot of money on the ECU and getting it mapped if it has working anti-lag and launch control, so you're lucky to have that. This is not something you can pik up at Halfords, it needs a specilist to set up and map and would have cost whoever fitted it over £1,000 Modern turbos can handle anti-lag as long as you don't go mad with it. Your pocket may not though... it works by adjusting the timing so it sparks while the exhaust valve is still open, thus sending the shock wave to the turbo which keeps it spinning at tickover and low revs. Great for hardcore acceleration, not so great for fuel consumption!

abzsti Posted October 29, 2014 Author Share Posted October 29, 2014 Gambit it is a fair machine, as I said in my welcome post it just needs the body work cleaned up and the interior sorted. Looking to have the car around 350bhp so 20ish to go Adam the car came with the dump valve. Just doesn't seem to be working properly Good news that the ecu is a decent one. Least I don't have to do anything with that :) Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted October 29, 2014 Share Posted October 29, 2014 Sounds like it's had a fair bit spent on it and with fmic ,tdo5 and yellow injectors it would probably see fairly close to 350hp but has probably been held back due to the anti lag and launch control putting extra strain on the transmission . of course you do know that this thread is missing one vital thing ... some pics :-) Quote Link to comment Share on other sites More sharing options...
