bigger injectors
Hi I recently got myself a Subaru Impreza turbo 2000 It has a standard engine currently running at 220bhp I want to improve the speed starting with small bits thinking of putting bigger injectors in. What's the best solution would I need to remap etc.

What year is it? Best thing to do is brakes first, possibly some of the handling components and then start on the engine. If yours is anything like mine was, the brakes are shyte. Get some 4 pots on the front at the very least.
To do it properly you'd need remapped. That alone will help. Then there's de-cat up and downpipes, exhaust systems, larger injectors, better turbo, the list goes on. All of which will need the map modified for.
I'm currently in a 97 Turbo 2000 with a few upgrades and over the winter I'll be fitting a TD05 turbo with 440cc injectors. It's currently about 280bhp at best. You also have to remember that the standard engine internals and gearbox won't take much more than this power for too long if you are hard on them.

If you aren't wanting to spend loads then I'd just leave it as is, fix your clutch and make sure the brakes are ok. These are renowned for seized calipers. You can then save up for a few parts and a remap in the future.

Ah, I thought you meant you had bought a Turbo 2000 which is actually the model of the car as mine is a MY1997 Turbo 2000 AWD.

If you have small hands and the right tools they are ok to change. I managed it just fine. Make sure the plugs have been gapped properly, 0.7mm I believe. Have you got the correct plugs? PFR6B for a standard car should be right.
The model is Turbo 2000 but the year could be different. What's the start of the reg number?

bigger injectors wont make the car faster, they will simply provide the ability to supply more fuel. if your turbo is standard it is unlikely to really trouble the std. injectors too much anyway. that money could likely be better spend on other mods before injectors became a limiting factor.

I will bare all this info in mind. Gonna start with up\down pipes etc. Then go from there. Just wanna do minor tweaks. But do I need to get it remapped everytime I add something onto her? Xx

Maybe not all the time but the best advice I could give is do everything at once. You'll find with de-cat pipes that the turbo will spool faster than the map can react to it and therefore would need the map adjusted. I had that problem.

as piehole says, gather the cash , buy the bits, then fit and map in one go to see the best and safest difference.
realistically the car more than likely wont show any negative signs from the small changes you are considering , but there also wont be any massive gains as the ECU will simply adapt its control to maintain the parameters its programmed to achieve.
What you wanna do is basically
allow it breathe more freely, so get air in , and away from the car more efficiently
so quality panel filter and full decat the exhaust.
then provide it with the fuel it needs, so ensure the fuel pump is up to the job and consider a walbro or the likes if not.
Then reconfigure the ECU to take these changes into account and possibly increase the boost a little also - a remap.
this should see you at the late 200's early 300's
then you can consider looking at a bigger turbo , which will require yet more fuel (bigger injectors) and more cold air (look at intercooler options) , and then of course you will be getting into the sort of power range where you will start breaking other stuff like clutches and gearboxes

If you are considering a decat then please take into account emissions test come MOT time. It will likley fail. There are ways around this, one is to keep the original exhaust and swap them around at MOT.

My mates looking at car next week. Just wanted to know if I could put the td05 turbo on, as I'm not exactly sure what my current turbo is. A mate said its a standard one but that doesn't really help lol,. You've been a great help today, thanks again, xx

theres different vesions of a td05, some will fit, some wont. its also not as simple as just strapping a bigger turbo to it and off you go, a good tuner is well worth the cost for your pride and joy
