stants Posted December 18, 2014 Share Posted December 18, 2014 What kind of bhp figures are you look for ? Quote Link to comment Share on other sites More sharing options...
aucky Posted December 18, 2014 Author Share Posted December 18, 2014 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 Posted December 18, 2014 Share Posted December 18, 2014 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 ? Quote Link to comment Share on other sites More sharing options...
quit Posted December 18, 2014 Share Posted December 18, 2014 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 Quote Link to comment Share on other sites More sharing options...

quit Posted December 18, 2014 Share Posted December 18, 2014 Get exhaust first then turbo and remap mate otherwise you will need to map again ideally Quote Link to comment Share on other sites More sharing options...
aucky Posted December 18, 2014 Author Share Posted December 18, 2014 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 Quote Link to comment Share on other sites More sharing options...

quit Posted December 18, 2014 Share Posted December 18, 2014 bigger the turbo the bigger exchaust you need 2.5" is good enough for about 350 bhp 1 Quote Link to comment Share on other sites More sharing options...

Mystery_Machine Posted December 23, 2014 Share Posted December 23, 2014 Would you not require larger injectors aswell? Quote Link to comment Share on other sites More sharing options...
craigie460 Posted December 28, 2014 Share Posted December 28, 2014 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? Quote Link to comment Share on other sites More sharing options...
Steveuk260.Esq Posted December 29, 2014 Share Posted December 29, 2014 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.http://www.andyforrestperformance.co.uk/58932.html Hope this helps.

craigie460 Posted December 29, 2014 Share Posted December 29, 2014 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?

kevf78 Posted February 28, 2015 Share Posted February 28, 2015 @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] Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
stants Posted February 28, 2015 Share Posted February 28, 2015 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 Quote Link to comment Share on other sites More sharing options...
Dino Posted February 28, 2015 Share Posted February 28, 2015 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. :) Quote Link to comment Share on other sites More sharing options...
