Right I have I 2005 blob sti running about 450bhp
It's the uk spec so looking at doing twinscroll conversion
Looking for a 500-550bhp turbo as going to do forged engine at some point aswell
So anyone know what best turbo is to get for that and about how much all the kit will cost and what it will cost me
Thanks Ryan

 

First thing id check is how much its going to add to your insurance, they really dont like young drivers and mods you know and as you were complaining about paying 2.5k for a 3k vectra estate (im 44 and one of the compare companies wanted 46k to insure me on a citroen c3 HDI ) it could be expensive.
Twin scroll wise, plenty of decent turbos out there, all new by the way so you wont be getting any deals on them, they range from about 14-1600 quid mostly, then with the engine rebuild (that wont be cheap either, a 2.1 is the way forward here but that will bend you over and shaft you with your insurance co), then you need the sump, dip stick holder and stick, new manifold so its not looking cheap for you....

Some users with twinscroll convert their jdm to singlescroll and they never will back to twinscroll-linear power delivery vs kick- some use md321v or gt30-35 turbo with standard sti engine. You could do rebuild after engine gone.
dont see reason in Your point to go for jdm(or twinscroll conversion) maybe spec c as its lighter a little

 

mate was going to do it to my bugeye i would not bother to much money + time involed just getting a billet turbo

 

Yeah might just go for gt30 or 35 not sure.... Decisions on what to do

 

Go for them and make sure you got deep pockets for supporting mods....

 

Yehh saving over next 12months so it's done properly
