hello have a 04sti guna get full 3" turbo bk exauhgts walbro fuel pump and alreadi got k&n filter and wanting to know before i go for a remap what opyion will be better. headers and up pipe or turbo and intercoller i am looking for around 360 bhp and simuliar torque. i use my car as a fast road car n posibly a track day once every blue moon. whats your recomendations?

 

you'll get 350hp ish with all those (headers etc) - if your wanting more than that then maybe a 2.5ltr bottom end and FMIC is the way to go.

A new induction looks and sounds good but its possibly to get upto 400hp with the standard airbox.

All these factors depend on what its running now, is it standard sti....265psi???

For 350 id say

Headers
full 3" de-cat
fuel pump
re-map


ps; don't forget the suspension mods if using for trackdays, can be more important than outright power on a track etc

 

As above, but definitely a Whiteline rear arb and drop-links, power is nothing without control...

As someone said !

thanks for the advice yes i am going to get either tein super street or kw varety 2 coilovers and basically all the whiteline cataloge lol.

 

Sounds just the ticket mate, a modded scoob is a match for anything, you only have to look at the spec c's to see what a proper modded Subaru is capable of, the spec c is definetely a good template to work towards IMO.

 

what would you say is better as a track car a standard spec c or a sti wid remap exaust induction n fuel pump plus coilovers and whitleline gear?

 

Spec C is an excellent out of the box track car, lighter, more uprated goodies and a great platform to make into an awesome beast.

But it comes at a price, it will be more expensive than an sti of course, but its the best, or one of the best scoobs you can buy IMO.

An Evo is really a better track orientated car than the scoob, but the spec c will outdo most of them, ask ScoobyTyson on here, he has one thats been tastfully modded with the right stuff for sprinting and trackday.

 

Most of the pros seem to go for a new turbo before new headers, e.g.:

Heasers and up-pipe will give you faster spool-up, but little or no extra power. You start with the turbo and intercooler. Actually, for 360 you could stay with the i/c you have (I know one person with 390bhp on an standard 04 top-mount) except it may be a problem on the track days.
