impreza number 3..........hawk sti
 
so im back in another impreza-couldnt keep away to be honest.

its a late 07 hawk sti

engine

forged 2.5 with a closed deck block built and mapped by scoobyclinic running 351bhp
mahle pistons
std rods with arp bolts
new crank
acl bearings
cosworth gaskets
heads fully rebuilt with upgraded valves/springs and retainers

cr turbos rebuilt and fettled with vf43 turbo
japspeed fmic
scoobyclinic induction kit
full set of silicone hoses
extreme lightweight flywheel
ap racing clutch
forge dump valve
denso 750cc injectors
3" de-cat downpipe
afterburner vortex backbox
hsd coilovers
perrin wing stiffies
defi gauges in dash pod
xxr 527 in a custom gunmetal paint

car has only covered 70k and is pretty much mint apart from a slight crease in the paint on rear bumber and a large stone chip on the front bumber.

future plans-

front and rear bumper respray along with spraying my fmic in silver

set of big brakes or refurb the brembos and a set of godspeed 2 piece discs

the hsd's are rusted solid so a set of bc's along with various bushes if needed and an anti-lift kit.

tyres all past their best so will order a set of vredestein ultrac sessanta from camskill as they are only £75 each at the minute.

would like a set of dtm mirrors but cant seem to find any

would also like to push more power but as its on std rods i guess im limited somewhat even though it has a closed deck block,perhaps 400bhp is
possible..........:wonder:

Nice car!

Sounds like it's be conservatively tuned from the spec. Having said that I've found that if I push too much boost at 3-3.5k rpm in 5th and 6th my hawk 2.5 shakes horrendously (torque groan) and the vf43 can easily spool that quick so if it's like mine it might be being held back on that account.

Otherwise from what I've read the general consensus seems to be 390hp on the vf43 and I was advised stock rods are good for 420hp in a forged 2.5.

Looks nice bud, glad to have you back in the saddle :thumb:

I would be checking the spec of that build though, I don’t think I’ve seen a closed deck conversion without uprated rods, not to mention paying for a new crank too :wonder:
I seem to recall one engine builder on here saying a rebuilt semi closed deck 2.5 should not be pushed above 380 but I’m unsure of standard rod limits.

Just to add, 350 bhp is a decent figure for a road car :thumb:

Spoke to kev at the clinic about The build and it is correct, the previous owner wasn't ever going to push to 400bhp so didn't want the expense of Uprated rods. Shame really but it is what it is

Thanks buddy, yeah it does spool quick. I don't get any shaking though

Well Iíve never heard of a 2.5 let go because of a rod so I would 100 % trust the build and mapping.
Maybe an sc38 turbo and map tweak closer to 400 is the way forward, would make great spool and torque, canít go wrong :luvlove:

Was thinking either that or an sc42

I would be inclined to stay within the build envelope with the best spooling turbo, aiming for 390-395 with an sc38 will make for a better car than turning down the wick on a sc42, as marginal as It may be I personally wouldnít introduce more lag needlessly.
Iíve been there and hated my car with lag.

On the other hand just leave it as it is, get it nice and warm and give it hell.... lol :lol1:

Yeah true, will be the last thing I do anyway as wanna spend money on other stuff for it. The engine has done 8k and was built last August so at least I know it will be reliable......(hopefully lol)

Merry Christmas would be so much more jolly by buying the side and rear lip extensions to compliment that nice lip at the front from ht autoís ;)

stonejedi 20 December 2017 03:10 PM

NICE!.SJ.

the shreksta 21 December 2017 10:06 AM

tyres arrived this morning.......0 messing around from camskill only ordered them 2 days ago. also spoke with simon @ chevron regarding my suspension and i think a visit is in order so he can see the car and talk through options.

:)

the shreksta 25 January 2018 06:45 PM

small update.....

front and rear bumpers resprayed along with my fmic sprayed in silver.

full set of godspeed g-hook discs along with new lines/fluid and performance friction pads all going to be fitted next week whilst the car is at chevron motorsport.

simon is removing my old hsd coilovers and replacing with his custom damper/spring combo along with anything else that would benefit the car.

also whilst its at chevron it will be having new tryes all round and a DAMD flat bottom steering wheel fitted............should be a totally different car when i get it back

next on the list is either a oil catch can or an air/oil seperator.

cheers

sivo 25 January 2018 08:23 PM

All sounds great :thumb:

Anymore info on Siís shock/spring combo ?

No not really, we only spoke briefly about it. I'm sure he said height adjustable dampers and custom springs. Will update on Saturday when I drop it off

the shreksta 11 February 2018 11:12 AM

Car back from chevron......me impressed
