Im planing on running a turbo kit (still deciding which one) how much psi can this stock engine hold with premium 91 (I’ll upgrade the injectors of course). I dont daily drive the car but I do drive it a lot on the weekend.  |
dude .. you can run 26 psi and rape these engines all day... lol
(I had a friend tell me that, couldn't believe he wanted me to take that seriously.. 10 psi on petrol is about the sweet spot but that is going to fluctuate slightly with tune and kit. max 350-360 fly hp)
As someone that's had this debate you are probably debating whether you need the beefier turbo. If so, well. Need 400 or more hp with E85? got ways to manage heat? Is primarily track or at all? Daily drivability an issue? Personally without beefing up the block going anywhere over 360 and near 400 .. total crap shoot how long the rods and head gasket will take it.
