Hi guys I'm after some advice for what turbo to get in the future for my sr20 Its kinda stock Apexi power fc 555 injectors z32 maf Fmic uprated fuel pump R8 coils A Walton manifold coming probably bottom mount with external wastegate (because I can) No vvti kinda aiming for around 340 to 380 bhp But also to future proof it if I wanted more. First thought was Gt2871r Then I saw the gtx2867r Then I saw the g25-550 I dont know enough to make a decision I no without the vvti I dont want lots for lag. Any help would be great thanks
Hi Chris, am in the same boat as you so would be interested to know too. I ended up buying this book but am only half way through, there is a good chapter on matching a turbo for your engine: Turbo: Real World High-Performance Turbocharger Systems (Performance How-To S-A Design): Amazon.co.uk: Jay K. Miller: 9781932494297: Books when I get to the end I will let you know! When you say 'no vvti' you mean you did the VTC delete?
for lets say 365 you want the Gt2871r I am also in the same boat as you and if you want fast response you want the Gt2871r, read things that it can handle around 400 but then you would need a pretty ideal setup etc. It isn't really future proof regarding 450hp isn't going to happen but 350 is more then enough in an s13/s14
