Evening! Have been away from Impreza's for a little while but will be returning shortly so I'm starting to make plans. I'm having trouble finding places that selling upgrades such as full 3" exhausts, air filters etc. for the Hawkeye STi type-UK, can anyone post up a few websites so ican sort out what i need please?
I'm particularly after -
a full 3" exhaust (with sports cat)
panel filter
fuel pump (walbro 255l, should be just the same pump as you'd fit in a modified classic right?)
plugs (pfr7b's? same crack as above?)
and numerous suspension upgrades (coilovers, whiteline arb's etc)

I know powerstation do most if not all the above, but I hardly recall finding any other sites that list parts for the Hawkeye

thanks

Ab

 

Hi mate, There are a few places that do the upgrades, i did up until december work for Graham Goode Racing in Leicester, They do a 370bhp conversion which consists of a 3 inch or might be 3.5 inch system with sports car or de-cat downpipe, K&N cone filter with GGR trumpet, uprated syntec fuel pump and also the ecutek remap which will give you around 370 bhp. Or if youve got deep pockets they do a 500bhp conversion. They also stock Tein coilovers and lowering springs, whiteline parts and various other suspension components. AP Racing big brake conversions 330mm and 362mm with 4 or 6 pot calipers. They can also get all the japanese sti parts imported, uprated engine components pistons, rods, cranks. They stock tons of stuff, look it up Graham Goode Racing - Home of Performance Specialism or call Glenn 0116 2835662

 

Plugs will be ILFR7H. Mine were from Contact Us but I think most tuners can now get hold of them.
Panel filter - K&N, Green, JP etc can be found at any tuners.
Fuel pump, again any tuner.
3" sports cat systems try Milltek or H & S but check that they true 3" systems and not ones that reduce down.
Revolution AKA Jetex are meant to be developing a sports cat to fit around the 6 speed gearbox, but I couldn't wait so have gone for a decat.
PowerStation
Stainless steel exhausts manifolds and headers from Hayward and Scott

A remap is a must, especially if you end up with a decat to stop leaning out and overboosting.

thanks lads, good stuff.

Butty, no need for a fuel pressure reg. if going for around 375bhp at most would you say? please say no as it was a right t-wat fitting those to my 2 previous classics a few years ago (i like to get among it and fit a few things myself, makes me feel better! lol)

 

I'm running low 90% injector duty at the moment on std fuel pressure & injectors - producing approx 350 hp and 380 lbft (delta dash figures).

Any slight variations in your final choice may well tip the balance and put some strain on the fuelling system.
I'd set a budget, chose some items and then ask the wisdom of your chosen mapper as to whether its the correct mix.

I wouldn't have your heart set on that 370 hp figure as I can't see where it comes from with the GG package. A new turbo wouldd definately get you into that territory, but would also need fuelling sorted out.
GG don't appear to be increasing the fuel pressure though.

Also spotted this on the website:
"Remap to prevent the Check Engine Lamp coming on because Catalytic converter is removed (no performance improvement) £295.00" - wonder if that's a hot seller?

Abby you cant go wrong with powerstation Im down there in a couple of weeks for a service so if you want anything brought back up let me know and I will fetch it round it will save you the p+p

 

cheers Gus, top stuff, I'll look into things

 

To max out the std components you will either need to upgrade the injectors or add a FPR to increase pressure to give it more fueling.

I was running 102% IDC on mine before the new injectors went in running in the region of 360-370

it really depends on where you ultimately want to go power wise though.

ScoobyMania Online Shop will sort you out with most bits you need.

All newage exhausts will fit if you get a complete system as only the centre section and downpipe are different on the hawkeye.
