Hi everyone, like the tittle said i have a turbo Honda Fit with stock block that i run at 6psi for about 2 years. I'm looking to change engine internals to run more boost and get more power but i don't really know what is the maximum boost i can get with this turbocharge. I don't want to change the turbo, i love the quick spool and i don't wan't to change the manifold so here is the listing of what i got :
- Garret AR48 Turbine
- Tial external wastgate 38mm
- Aluminum front mount intercooler with pipes
- Stainless up-pipe and down pipe 2 1/4in
- Sequentail blow off valve
- O2 Fix
- Cast iron exhaust manifold
- Greddy Emanage (Ultimate) With based
- RC 310cc injectors with clips
- DC Sport 2 1/4 Stainless Steel Cat-Back

And here is the listing of what i want to change:
-Injectors for 450cc minimum (RC probably)
-Wather-Meth injection
-Cp Piston 11.5:1 CR
-K1 Technologie Rods
-Custom CNC machined blockguard
-27x7x2.5 Fmic

Feel free to give your opinion about what i wanna do but the onlu question is how much boost this little turbo can push and handle.

Thanks

 

No point in changing internals. Maximum boost is 14psi, after that it's a hair dryer.

 

All right so i can run it at 12 psi without problem

 

YEs that will be fine just get a good tune.

 

All right thanks guys!
