i bought a bugeye wagon wrx few months back and am looking at starting a few mods what power should i expect from the following. (feel free to help suggest etc as im not mod minded lol)

1,walbro fuel pump
2,wr sport back box already on car
3,de cat center section
4,2nd cat replacement de cat section
5,de cat down pipe
6,de cat turbo up pipe
7,in wing air intake
8,japspeed fmic
9,re map time

and would i only have to change the de cat down pipe for the standard cat pipe for mot or would i have to re map again? any help would be appreciated thanx

 

Hi matey from this parts fitted you will see around 270-280BHP,and if you want MOT friendly downpipe,i will recommend Sport cat(cost around 160-200£ from Cobra Exhaust).At your current stage FMIC is useless(FMIC is recommended if you are going up to 400BHP),i will recommend change WRX TMIC to STi 7/8 TMIC.
Or just wait until you are source VF35,TD05-16G and STi pink injectors and with this setup you will see around 330-340BHP.
Cost of remap is 300-350£ for open source remap and 500-650£ for EcuTek.
And for remap,i will recommend contact here Neil@Slowboy Racing,Rich@FB Tuning(fiestaboy),Duncan@RaceDynamix and JGM

 

I wouldn't bother with the front mount yet. Standard WRX intercooler is good for 320 to 330 bhp. Similarly with the air intake. Decent panel filter in the standard airbox is fine.
Your suggested mods should see 260 to 280 bhp.
Have you already upgraded brakes and suspension?
