Hey guys. I am looking to upgrade my stock Intercooler and Fuel Injectors and wanted some input.


My current Mods:
Injen Intake w/UICP
Tomei Titanium Turbo Back w/ Test Pipe
Grimmspeed MBC
Wideband Air/Fuel
Tuned at 22psi (road)


I am looking to get the ETS 4" intercooler and FIC 775cc injectors so I can increase boost a little more. I understand I have to have a re-tune afterwards but was wondering if I increase boost, do I have to replace/upgrade the stock bov. I heard they can hold about 25psi.


The car has never been on a dyno but anyone out there with similar mods know what #s I should/could expect once the new FMIC/Fuel Injectors are put in maybe at about 23-25psi?


Any input is greatly appreciated.


Thanks.

 

No need for injectors on stock turbo unless you want to run E85. If you're running out of fuel, check the fuel pump relay, and/or replace the pump with an ASNU 330 pump. 3.5" intercooler is plenty big for up to ~800whp, no need for a 4".


Ditch the MBC, and use an EBCS. The X has really good boost control strategies, no reason not to use them. Stock BOV is fine for the stock turbo.

 

Ok sounds good. Thanks for the input.

 

My 08 made 340/345 @ 25psi with basically the same mods. Only other mods I have are a buschur intake and fuel pump. I don't see an IC being beneficial unless you're planning on going past 25-27psi and want to run ethanol. In which case go with FIC 1100s and a 3.5" core.
