Ready for a map what's next
Hi got a GB270 wagon Im in the middle of buying a few bits for the car so the mapper can Just do it all in one go I think these cars are 266bhp standard and I'm pretty sure it's standard anyway. I'm buying 3" pipe turbo all the way to the back. Already bought a 3" cobra back box and Kn panel filter. What else would anyone recommend I do to it? before it goes to the mappers cause I want it to be safe without missing something out and then it going bang ha thanks

Full service,fresh oil ect and make sure the mapper is a decent one.
You could fit or get the mapper to fit a 3 port bcs(if it doesn't already have one) for better boost control but its not a must.

Hi thanks for the help it got serviced about 1000 miles ago it had all the diff oils changed and plugs. I'm new to all this so bare with me haha what is a bcs?
Uprated fuel pump!!
Personally I wouldn't push it to much mate, Im guessing you have read the numerous threads on here regarding the 2.5 litre engine. I managed 380bhp/412lb ft on a standard STi 2.5 engine so i should be the last one telling you to be careful!!

Haha yeah these engines are a hit or miss arnt they? o well if she bangs she bangs it only nuts and bolts haha. How long did yours last?
Going for a map, then go all out!!!!
Heat blanketed TDO5
STI injectors
255l Walbro fuel pump
Silicone inlet hose
Do-Luck Panel filter
STI top mount intercooler & hoses
3 port boost controller
Low friction Millers Nanodrive engine and transmission oils
Decatted heat wrapped up-pipe
Heat wrap downpipe

This relatively cheap little lot will see you beat any production Subaru over 1/4 mile.
They say getting a WRX over an STI is the worst mistake, it isn't, getting a map after every mod is the worst mistake!

Exhaust, panel filter, fuel pump, and then remap.
Many opt for a Walbro 255 pump. I had an HRC 255 on my Impreza for the last nine months or so of ownership and it performed perfectly... and it was only £50!
As for mappers, personally I'd make the trip across to Scooby Clinic in Chesterfield and use Pat Herborn, but as Cilla used to say, the choice is yours!

Up to £2000 inc map as most of those parts can be found dirt cheap, but you will have a bloody fast Impreza.
+1 for using Pat Herborn too. The Clinic are **** hot these days.

Why is there so many colours of injectors to buy the higher the cc on the injector does that mean they are better I really I new to all this stuff ha sorry if my questions sound daft
Up-pipe and downpipe have a cat in if I remember!!
Another free mod if you got the tools to do it, is Port and polish your headers, makes a difference, usually make the turbo spool up 500rpm sooner.

Many people recommend them but I wouldn't go there personally. I have 2 cars that have been maintained by them and I found a few big issues shortly after I've bought them. I have phoned cams asking for some advice but guy was very unhelpful so I ended up in Scoobyclinic and I'm glad I did 

it's just a bit of a mooch for me to Scooby Clinic I'm in Manchester. And does anyone have an STI intercooler, fuel pump and bcs maybe some injectors too for sale????
From what I can gather, you're going for Stage 1 mods. For this, all you need is fuel pump, decat/sports cat, panel filter, and then remap. This should get you to circa 290 bhp.
You don't need a solenoid, bigger intercooler (and undertray), or bigger injectors unless you want to go for the next round of mods, eg. bigger turbo, which, depending on turbo choice, could take power up to 350ish. These additional parts (turbo, injectors, intercooler with undertray), if bought used, would probably cost you a further £600-ish.
If you want to do the latter, as Matt said, it's more cost-effective to purchase all the necessary parts first, get them fitted, and then get the car mapped, rather than do Stage 1 mods, get a remap, then do Stage 2 mods, then get another remap. Although saying that, you wouldn't save that much. Once you've had an initial map, any subsequent map tweaks should only cost about £100. Labour costs might be slightly lower, too, but personally I'd go for Stage 1, enjoy it, then after a year or so, once you've become accustomed to that power and are hungry for more, move on to Stage 2.

see I don't even know what exhaust system is on my does it have two Cats or what.
Best thing to do is speak with a reputable Subaru specialist, tell them what you want, ask them to quote you for the whole job, parts and labour, and then just get the car booked in. They will buy all the parts for you. Obviously arrange to have the car mapped as soon as you can afterwards, though. Some places, eg. Scoobyclinic, have a workshop, so can fit the parts, and then have their own in-house mapper, who will map the car straight afterwards. They'd have your car for the whole day, but that would be it, job done!
However, for Stage 2 mods, it would be far cheaper to source the parts (turbo, injectors, intercooler) yourself second-hand.

Ok cool thanks. What sort of turbo do I require and coloured injectors and so buddy? Is it bigger the cc's on it the better??
I thought you only wanted to go Stage 1 for now, lol?
If you do want turbo and injectors, that's a whole different debate. I'm not 100% sure for a GB270, but I reckon pink injectors (550cc) and a VF35 turbo would be a good call. Happy to be corrected, though. Used, you could get those for £100 and £350, respectively.
The higher the power you're going for, the bigger injectors are required.

I will do thanks for your help.
Ok so if I buy my straight through exhaust from the turbo to the back put an air filter in like a panel one and a fuel pump and I don't get it mapped straight away until I save up for Turbo, intercooler and injectors will it cause damage to my car?
It's got 2 cats afaik, downpipe and centre section. 2001-2005 seems to have the small cat in the up-pipe, does the Turbo 2000 have one? A performance up-pipe like the Harvey Smith trick up-pipe isn't essential though, it may improve spool by 200rpm and bhp up to 5bhp maybe. Every little helps though imo and mods do work better together.
One other thing to consider is if you use Ecutek mapping software other mappers will charge a bit more to perform a second map down the line if you fall out with the initial mapper, as it will be a full map rather than tweak.
I'm not sure how it works with secondary open source maps.
