hi everybody im new to the lancer evo community 2 months ago i bought a evo with a chassis of evo 4 (CN9A) but the body kit is of evo 6 i like the car its powerfull and very clean.
I would like some help with the engine i would like to tune it a little bit so i can reach at least 350hp the turbo of this car its a TD05HR 16G 10.5 and it has a greddy emanage blue ecy

question
1.the engine is stock if i raise the boost to 2bar will it be ok?
2.if i put HKS cams on the engine 280s i guess will i need anything else or its ok to use them on stock engine also will i feel the difference?
3.i found a 18G wheel for my turbo will it be more powerfull if i install or just the same

thanks in advance this forum rocks

and if you can what tuning mods can i do externaly to get more power?
