2000 impreza turbo tuning
 

I have just bought my first impreza it's a 2000 impreza turbo (2000) I love the car but just wish it had a bit more power.I was wondering if it was possible to get it to 350hp.Engine has been forged and it has a blitz nur spec exhaust front to back and decat.Next step was walbro 255 fuel pump,pink sti injectors and td05h turbo then a remap would this see me close to my goal.Also it has a bigger top mount intercooler from a later model sti.

pink STI injectors are for newage cars mr they won't fit your engine I believe its the yellow ones you want. You'll also be on the lookout for a larger intercooler, fuel pressure regulator and some grade 7 plugs.

If your serious about your goals then consider replacing the ECU with something that can run MAFless - I'm not sure if the ECUtek remap for classics can support that but I know you can do it with simtek/ESL/apexi alternatives.

Check out the andy forrest site for a guide to what mods will make what power:

Thanks for the reply I have just had a look through the site you recommended it's a great reference of how to go about achieving my goal

The MY00 car will come with yellow 440's as standard. Not sure they will go as far as 350bhp. You can get 500+ side feeds but they are a bit harder to source. Or do a top feed conversion and use the STI pinks or other after market top feeds.

You can only run mafless with a different ECU.

Turbo, injectors, pump and fpr will see you to 350 with a remap but your gearbox will be the next thing to need attention.

With regards to intercooler you can fit bigger top mount or a fmic and induction (but not great for MAF's). However I am fairly sure the standard top mount will make 350 but will clearly be better with a bigger cooler.
