right, ive got circa £600 to spend on mods.

i am new to the newage imprezas so need some help if you dont mind..

i have a cat back exhaust (ninja 2) and a induction kit but looking to buy a standard airbox with a panel filter.

so i would like the following;

decat downpipe
front splitter
any other engine mods to get as much power as possible.

i cant seem to find the downpipe i need as i have no idea what size i need to fit the rest of my system!
what splitter is best, i like the sti one on this page..

I have the HT autos splitter myself.Im very happy,BUT,for a little extra,JM carbon have got a carbon splitter on offer at the moment,it looks awesome!!!
For me anyway,it may be time for a change

a little more? is almost double in price for their carbon one Having said that I might get one as I cracked my ht autos one

rich09

I was going to get the carbon one but I thought coming up to winter is a bad idea..
Is the japspeed decat downpipe any good?? 3" with a 2.5" connect? Will this fit my existing system?
Thanks

Yeah,fair enough,but its free you know if you put it on your credit card

rich09

right, ive bought the ht autos splitter and a japspeed decat.

what else do i need to get my 330+ bhp??
can i just get a remap or do i need a new ecu? (dont know what a ecutek is)

so i will have
full decat
induction kit

Your ECU is mappable like via EcuTek or Open Source(contact here Duncan@Race Dynamix,Neil@Slowboy Racing,Graham@Engine Mapper,Rich@FB Tuning).Open Source remap is cheaper and give you same results for less cash like Ecutek.

For 330bhp+ you don't need induction kit,just fit uprated panel filter like K&N,Green Cotton etc,3-port boost solenoid,Walbro 255lph(HRC are great and cheaper than Walbro).

induction kit was already on there. i thought they had 3 port BS as standard??

this what i need?

Not sure about the 3-port boost solenoid,i know some Impreza have some no.

Now about the Induction kit,on your with no power mods i would suggest re-fit OEM airbox with good panel filter.

I have a standard airbox setup and panel filter all you need £40 posted

rich09

i will be putting the oem box back in but i need to source one.

are the fuel pumps hard to fit??

Wmscooby

As above with the airbox

rich09

sorry, missed that. what filter has it got?

will i need to get it mapped to notice any gains with the newly acquired mods??

Wmscooby

It's in the loft over my garage so will check in the morning whatever it is its like new!

rich09

thanks

I would fit everything before day of remap(3 port boost solenoid i would leave on mapper,he will fit),because you must run off the boost to remap,due decatted exhaust can cause overboosting(boost spike).

Which induction kit you have fitted?


Jura

Will do

Just on this whole point of remapping. Is it really necessary to fit a sports cat downpipe and decat centre pipe, in order to get circa 300 bhp from my bog standard 2005 STI.

Its got a Prodrive back box, so if I just get a panel filter, will this be enough for a remap to around 300 bhp? Cheers.

rich09

what happens if i fit the decat to it before mapping it? why would it be worse as i have a cat back already..

thanks

Absolutely, catted dpipe is very restrictive, so get the sports one, plus the other bits u will see minimum 320-330.

It has a brand new blueprint filter so basically standard matey

£40 posted for the lot full set up let me know

Mark

rich09

why is a standard airbox set up better than a induction kit?

are fuel pumps hard to fit?
