hi i have a impreza bugeye non turbo and want to get more out off it i no alot of you will say no point and to buy a turbo but sadly thats not an option for me (wish i could lol). iam not after top speed just bit better throttle response and just to pull a little better through the gears. i have allready removed both airboxes and fitted induction kit and fitted a ninja cat back exhaust but not 100% wat i can do next apart from lower it.

hope some can help

 

i think your pretty stuffed mate, theres not a lot you can do powerwise to a n/a impreza.

 

It depends that are you after bolt on mods or are you willing to spend lots of pounds on it and take the engine apart?

 

there must be somthing that can be done to get better throttle response tho. i have fort about going down the remapping route as been told by a mate that will help get better throttle response but dunno how true this s

 

I have tuned some n/a Alfa's in the past and custom made exhaust headers and decat gave better throttle response and relatively pretty good hp gains nut they were 3,2 lumps.

Could swapping an svx engine be an option for you?

 

Pretty sure Scoobyclinic do N/A remaps, but you won't get a great deal out of it, perhaps more throttle response. Only one way to find out really!

 

nitrous

 

In my expieriences remap on n/a car is a waste of money unless you have done cylindrer head tuning, better cams and headers with full decatted exhaust before.

Is it possible to bolt JDM STI's avcs heads to n/a impreza? Maybe some one with more experience could tell? Have you consulted any professionals yet?

 

only looking for better throttle response not really bothered about top end performance. think ill have a ring about tomorrow and see what some tunning companys suggest about remapping.. cheers guys

 

I have this feeling that nitrous without forged internals can not be any good

 

Cheers mate, these things allways start with those words and end up in having a performance monster

 

hahahaha if only :-)

 

one word, superchip...............i think demon tweeks do this as i had a n/a bug before i had my bug turbo, which there was a chip in it, it did it good

 

Take off the inlet manifold and fit a pair of carbs on a custom inlet manifold for either side of the engine.
A Subaru engine on carbs would be awesome to see and hear.!
