Hi all 

sorry to jump in but just looking for feedback 

I have 26/30 with big cams and want to run a set of garret 25-550’s 

will the 3l have enough puff 

Street driven 32 

 

cheers

Hi there thanks for the above. 
what attracted me to the 550’s is the new technology but to be honest I wouldn’t have a clue possibly there’s better suited turbs  

dyno Will be hub type in NZ lol

my friend is running /5’s on a rb26 on pump gas making 430kw (hub dyno) - so with my situation 3l block and slightly bigger turbs on E85 we should be able to hit 500kw mark with out to much effort  

 I recon the correct comb is out there there’s no info around as everyone goes single 

So do you think I’ll need 30lb plus boost to hit target? is it possible to change rear housing. 
 

(ripper) yea bro I’m excited

I’m look to run a set of the new garret g25-550s on my rb26/30. Aiming for a vicious 30dett
Will have to find the cam card but from memory. the head has a set of kelford cams 10.8mm lift and 280 degree duration  

the block is forged and balanced 

engine is going into a street GTR

Yes I could go single but just want something different 

What you all think will the 3l have enough puff 

aiming for 700+
