hi all, been here for awhile. but finally started posting and trying to be active on the boards. hopefully i will have my 05 apex silver evo XIII soon enough. i'm curious i want to add a intake, exhaust, bov. out of those three what are the best aftermarket parts to get with the most significant gains?

 

i wouldn't get a bov, just crush the stock one and you can hold any amount of boost you want, within reason. exhausts are just piping, but from what i've seen buschur is decent. intakes, i dunno, but aem intakes are always reliable.

 

I agree with the poster above, there is no need for a BOV, unless you like the sound. Exhaust in my opinion are pretty much just piping and I think a lot of units for sale are over priced. You can pick up a ebay 3 inch turboback exhaust for $300.00 or less and make the same power as the more expensive ones (but make sure it is a true three inch exhaust). Although I do believe there are some really nice exhaust units like Buschur which I believe is worth the cost.

But as far as which bolt on adds the most power, it is kind of hard to say, but I would say the Turboback Exhaust, but the most important is the tune.

 

turbo back and cams.

 

A drop in filter and a turboback exhaust. Don't even think about replacing your BOV yet.

 

Forge DV FTW

 

3 inch turbo back exhaust, buschur cone filter, evo 9 bov, and a tune.

 

youll also want a fuel pump and to search

 

42r,ported head,and strocker....some basic mods

 

yeah throw those in and call it a day

 

I've seen significant gains from a TBE, intake, and cams. Increased throttle response from an O2 housing and UPIC. I've also added an ignition amp (Sun Auto), which also "seems" to aid in throttle repsonse--no measurable gains.

 

MBC and flash
