Question about turbos

[aucky]

Hi guys.If I was to fit a bigger turbo to my wrx, say a sti turbo, would anything else need changing apart from havin a remap.N will I get more bhp after a remap then with my wrx turbo.[emoji12]

What kind of bhp figures are you look for ?

[aucky]

I'd be happy with about 300bhp for now when I got my car it was boosting at 20psi becouse of a bust hose, now I have fix that it boost at 10 psi and just feels a little flat, it don't have any kick anymore, couple of people who have nosey ed at my car have said , not bad but it's only got a baby turbo on you need to stick a bigger 1 on like a sti, so it got me wondering if it would be a straight swap or would I need to fit a sti exhaust or wrx, would my induction pipe need changing, stuff like that, would the extra bhp I got be worth the extra cost?

[stants]

Maybe uppipe cos yours should have a pre cat in it but I'm sure new age owners will be along in a bit to confirm. Have you already got an aftermarket exhaust ?

You will get more power just need to swap it over and map

But extra supporting mods will make the best out of it tho

[aucky]

No stants not go exhast yet, it's just got a back box on was on car when I got it so don't no what make it is, been looking at the afterburner rapter from scoobyworld.

Get exhaust first then turbo and remap mate otherwise you will need to map again ideally

yeah matt its my top priority after the xmas hols, this may be a daft question but I guess a 3inch pipe is better then the 2.5inch pipe, and they both will fit my current and new turbo

Depends how much power you want

lots, more the better , can never have 2 much power

bigger the turbo the bigger exchaust you need

2.5" is good enough for about 350 bhp

thats good enough for me for now

Would you not require larger injectors aswell?

kinda hijacking the question but seeing as it is about turbos.... what sort of bhp can I safely achieve on my 2003 Blob stis standard turbo?

I personally would aim for 300 bhp as a good reliable mark.

Hope this helps.

Cheers Steveuk260. I'm running the PPP pack on my car too so I think its sitting at 305bhp. was hoping for some tasteful safe mods to take it to 330-350bhp. That might need a change of turbo then?

@craigie460 should be fairly safe to invest in walbro uprated fuel pump and a good remap should see results similar to mine and take it to around 330bhp if that helps [emoji2]

I'd look at other pumps than the walbro's they seem to be getting a bit of bad feed black recently due to workmanship & construction going downhill

I tightened up all the air hoses and put a fuel clip on the looser small hose connection after the MAF. When there's no air leaks, the power and response is really improved. :)
