B18B1 psi to run with gt35
I have a stock internal B18B1 in a 94 civic Lx and I'm not sure what psi is "safe" to run with a vms gt35 (I know this is a big turbo for stock motor)
The car is street tuned on crome by me with a Aem wideband on 11 psi right now. I ran it for a while at 14 psi on some shitty base map with stock fuel pump which is why its blown up twice So what would be a good psi to run and make a bit over 300 whp. |

Why not just go with an equally cheap 50 trim?

Well I already have this turbo but I probably will downgrade in size if I don't build the engine soon

10-12psi should do it.

Re: B18B1 psi to run with gt35
You stated it is at 11psi now. 1 bar gets you double the power. A B18B, Figure in the losses. Shoot for 20 psi. 4x 750cc minimum injector size.
Look at injectors. You need a certain size injector to make a certain level of power. No fuel , no power. There are some members rides claiming they are making 'X' , look at turbo size 50mm, 60mm, then injectors 600-750-1000cc. Make an educated guess. All my projects did really well with about 1 bar of boost. I tune em up and they drive really nice. If I made more boost than 20 psi , it would not happen in the lower gears. Like the end of 3rd or 4th . A reasonable sized turbo will make more boost through 1st and 2nd. If you are doing your driving in the city that is something to be aware of. How much pedal will you need to get into boost? To get it to actuate the BOV? The big 'uns get kinda lazy. |
