Hello, I have my evo 8 here and I’m looking to make around 400whp as reliability as possible. I have a list of things I think I need and I’m just looking for some input as to whether or not I need everything on the list or if I need more. For reference I’m currently sitting at 290whp with an evo X bov, 2.5in dp, hfc and catback, walbro 255, grimmspeed boost controller and lower ic pipe.
The list I’ve come up with is as follows:

FP Green (used rebuild) - $1,100
FMIC - $400
Upper ic piping - $280
3” downpipe - $130
3” turbo elbow - $100-150
O2 housing - $150-250
STM Evo 9 Turbo Install Kit - $450
SD intake + sensor kit - $470
Injectors 1000cc - $600
Fuel pump relay - $25
Competition Clutch Stage 2 - $650
Spark plugs NGK BPR8ES - $30

Hello, I Have my evo 8 here and I want to reliably make around 400whp. I’m currently sitting at 290whp with just a full exhaust and 2.5in dp, lower ic pipe, walbro 255, and grimmspeed boost controller. I’m thinking of going fp green but I also want to know what else I’m going to need to make this as reliable as possible but without paying a fortune. Any and all help is appreciated, thanks a lot. I have wheels coming in as well, 18x9.5+24 and I’m wondering what tire and tire size would be best to daily if anybody has any recommendations.
