Fastboy67 Posted March 17, 2015 Share Posted March 17, 2015 Hi looks a great forum with lots of helpful advice from you guys. Finally got the car I wanted after years of yearning for one and the other half hating them not that I worry what she thinks of my now pride and joy. :D Any way to the crux of the matter, it seams I have a troublesome sensor either at the front of the exhaust or near it can't remember what the garage said now. The engine light came on but with no loss of power that I was expecting (ie get you home mode) Turns out to be the lambda sensor I think its call as the previous owner had the same fault show up on a diagnostic test. The garage said it need more time to investigate it but it could be the said lambda sensor of faulty cat. It got me thinking is it worth having a de-cat pipe? I was toying with the idea of taking the car to scooby clinc for the work and having a front mount intercooler added at the same time. Seams they have a good reputation. Any suggestions and advice is greatly appreciated. Quote Link to comment Share on other sites More sharing options...
stants Posted March 17, 2015 Share Posted March 17, 2015 Hi welcome, feel free to get stuck in and get some pics up [emoji16] Lambda sensors are a weak point, if your handy with spanner it can be changed in 10mins. If you buy a cheap odb2 scanner and an app for your phone you should be able to determine if it's the front or the rear, As for decatting you'll need a remap as it will bring the management light on permanently, also could cause over boost issues. How much of an increase in horsepower are you after ? As a front mount isn't really necessary on new age cars unless you want to go above 350bhp This will also require mapping in, if you were to go down the remap route you'd need to budget for an uprated fuel pump to avoid running lean under increased boost. 1 Quote Link to comment Share on other sites More sharing options...
Fastboy67 Posted March 17, 2015 Author Share Posted March 17, 2015 Thanks for the advice on the lambda I might have a go my self then sounds easy enough. I probably should of mentioned when I bought the car it came with it already remapped to a supposed 355 on the print out which was done over 18 months ago I think. So not really expecting it to be still that high but somewhere near would be nice. It had again according to the paperwork that came with the car that the fuel pump is uprated and it got a 3 port valve read up on them and still not sure what it does but it works. So yes looking at the front intercoolers as the figures should be up around there and I'm aiming for around 400 eventually money being available. Are they easy enough to install and would that need the map doing as well? So the de-cat will need the map sorting and I take it I'll have to fit it back on for MOT's.

Jay762 Posted March 17, 2015 Share Posted March 17, 2015 Wotcha and welcome - great looking motor with some nice mods. I would get the map checked if you run the decat pipe, given it has already had one it would be better to get the parameters checked. FMIC would be a complimentary addition if it has had those mods done - not sure about the fitting - attaching it wont be an issue but I dont know if there are any bodywork mods needed. Mot - depends on your tester, might get away with out changing it Quote Link to comment Share on other sites More sharing options...
stants Posted March 17, 2015 Share Posted March 17, 2015 I'm guessing at least one of the cats will have been removed already or a sports cat is in place as you'd struggle to get those figures with both cats in place, Possibility of why it's throwing an eml code too. 3 port solinoid controls boost better than a 2port one. So mappers usually install them when going for loads more than stock boost. Front mounts usually require some cutting of the inner wing and maybe the front beam. And you'd need to have the map tweaked as the volume of air and distance it needs to travel is going to upset the running of the car. Any idea what turbo is on there, you may need to go bigger to hit 400. It wouldn't be a surprise if the cat is still putting out the dyno figures quoted as mine's nearly 20 and makes over 200bhp 1 Quote Link to comment Share on other sites More sharing options...
tom_gr7 Posted March 17, 2015 Share Posted March 17, 2015 Hi welcome to the forum, I cant offer any advice about the sensor. But i'd suggest going to Sheffield Subaru Service for any mechanical work that is required. I've heard that Scoobyclinic is a tad expensive and apparently you have to sign a disclosure that states any jobs they find on your car (whilst they have it) they will fix them and charge you for them. Also, we've got a small meet on Saturday in the N/E that you are welcome to come to. :) - http://uk.subaruownersclub.com/forums/topic/12370-the-first-ne-regional-meet/ Quote Link to comment Share on other sites More sharing options...
Fastboy67 Posted March 18, 2015 Author Share Posted March 18, 2015 Thanks lads great info there for me to digest. Think the car is still running an original turbo as I haven't found a receipt for one in the literature that it came with. I plan to have the so called minor jobs done first before looking at a change of turbo Having everything in place ready to go for the 400 mark. So its minor mods for the engine to prep it, possible suspension was thinking tein coilovers but having found an earlier post not so sure now. And more importantly better brakes to stop it. The meet sounds great unfortunately I work away hence the silly post times lol, and wont make this one but do you organise them on a regular basis ie once a month or is it just as and when ? I'll keep a look out on here for other meets I don't mind a bit of travelling. Thanks Quote Link to comment Share on other sites More sharing options...
Dino Posted March 18, 2015 Share Posted March 18, 2015 Recall I posted something about Lambda sensors here a while back. ... have a search and see what's here. If it is the Lambda then it will run ok but use more fuel. It's more likely to be the front one. Quote Link to comment Share on other sites More sharing options...
Ash007ks Posted March 19, 2015 Share Posted March 19, 2015 if you need a Lamba sensor i have a nearly new upgraded one for sale :) Quote Link to comment Share on other sites More sharing options...
