Thinking of buying an 03 STi UK with low mileage and a few mods done like an exedy clutch, rebuilt VF35, RCM filter, de-cat exhaust, 255 fuel pump.

It hasnt been mapped as the mods have only been on a couple of months and its barely done any miles so if I do buy it and were to book it in for a map what should I consider doing to it beforehand?

Engine/brakes/suspension are all fine so I can concentrate on performance enhancing parts but dont have the ££ to go for an MD321T. I will have to stick with the VF35 or similar and an open source map. I will have funds available for mods, just not a chunk of cash in 1 lump so have to take my time. The car can sit in the garage til its ready

Question is, whats needed to see 400bhp? I know the VF35 will get close to 360 in some cases but is an MD321t the only option past this point?

Advice is appreciated.

you'll probably need injectors

I'm running sc42 on mine and its making 424bhp. U will need 740cc injectors and maybe a fmic. Headers and up-pipe and at least an ecutek map. I use Jgm for my mapping
