i have a 95 wrx import, it's blown at the mo but when it's fixed it'll have:

sti block
turbo back straight through zorst
green filter

if i buy an Apexi boost controler and up the boost to 1.1 bar will i kill my engine???

 

bttt

 

i would presume if you monitor the fuelling and afr it would be fine.
Are you going to uprate the fuel pump (possibly the fuel pressure regulator)?
Worth checking www.enduringsolutions.com for their chip as it changes the boost pressure to 1.1bar.

 

will prob go for a 225 fuel pump but no idea on a regulator

 

fuel pump will be a good addition anyway especially if you come to add further mods at a later point.

Can only compare with my previous UK97 which happily ran 1.1 boost with a TD05 for a year or so. Later added a FPR along with an Apexi ecu mapped by Andy F and raised the boost again to 1.4. No issues running like this for two years and I know the car is still running strong.

Had knocklink and Llambdalink to monitor things
