Yep... back in the day H&S were the daddies in performance exhausts, and there were many other firms trying to match their products. I personally have had H&S decat and sportscat down pipes previously FWIW. I guess what I was trying to say was that some of the competitors have caught up and make equally good products now too...

My point in making more power with a sportscat rather than decat was a positive comment on how well a 200 cell cat can flow. AND... I have read on SN of some of the 100 cell cats that struggle with emissions at MOT time.

To the OP - get what you want to complete your system - be it all H&S or whatever. I was just offering an option.

Andy F is a Lord in Subaru tuning so we wouldn't want to disagree with him.

Another interesting point is that when my car was first built it ran 365/365 with the H&S decat d/p and 2 1/2 " system. An identical car (barring my flowed heads) with H&S full fat 3" decat ran 355/355.

Am I comparing apples and oranges ? No. Point being maybe a 2 1/2"
system isn't restrictive at this level of power (or some say into 400+).

Its all smiles ...

was changing my side lights today and had the air box out and noticed a tube on the bottom that was sealed, on scottish scoobies some one has a HKS intake funnel fitted to this tube on their STI what i want to know is can i open this tube up on my WRXS with no ill effects or would i need a remap? I would rather take a cold air feed from my lower grill than fit the funnel but i thought i would ask first

 

If you have a look on some off the us form thay have it done I have done it on my one with no map as yet seems to be ok you hear the wast gate more

 

The part I'm mostly getting at is That I was told the self same thing about the H&S 2.5" flowing better than the 3" counterpart due to the bends on the exhaust restricting flow.

Mine quite happily runs a 2.5 Inch system from H&S one of the very first ever made & has never been an issue with restriction's running the power level it does. Dyno'd at 420bhp/450 ft/lbs. the only time it will be getting changed to a 3" system is when the new engine goes in with it's rotated turbo setup

 

so what power are you going for with this new engine cant wate till i can aford to do my one wish i had your skill to do it my self

 

A few pics of my hatch

Prodrive GT2's

 

good choice of colour

 

GT2's are the best.. are you on 19"s?

 

Yeah they are 19"s

 

same as mine then





a set of 17" STi alloys will be going on in the next week.. after its been serviced next Saturday.

 

got my old 330s alloys gold for the winter

 

I just had the Subie a fresh service made and (unfortunately) the winter tyres installed. Ugly 17"

From these (18" 9" ET35)...


To these "studded" (17" 8" ET53)...


Looking forward to the Swedish winter ALOT now!

Also I had the intake silencer removed and a HKS panel filter installed. Makes the car goes swooosh and pyyysh when shifting gears No gain in HP though...

 

mine for winter

 

550-600bhp but realistically most likely with my turbo choice 650+ I keep changing the boundarys. I'm changing the valve train in the engine to open up the revs too which will help. 6500rpm is **** bring on 8500-9000rpm.

My advice to anyone doing a home build is measure everything twice and you wont go wrong & dont be ashamed to ask for advice.

 

Stu.... I like that rear spoiler mate. what make is it.

car looks wicked

 

Oh no, not again Rob, you know it didn't end well last time!

 

I need to step away from the laptop lol. I've other things to sort first haha

 

It's the Imex Design one...

 

when you removed the intake silencer and fitted the panel filter did you have to make any other mods to the airbox or was it a straight forward operation?

 

Straight forward, nothing else needed

 

Heres my STI. Its got a powerflow twin 4" exhaust burnt tip, HKS dump valve and team dynamic 18s. Many more plans to go!







Ill try and get more up to date pictures soon as this was when i got it a couple of months back

 

Nice ride Jack!

Also, I think you look just like a typical English dude

 

tracky bottoms & a hoodie?







btw.. does everyone have a mark on the metal in the engine bay where the bonnet comes down and rubs the paint away cus of the plastic trim fitted to the bonnet?

 

haha thats my brother but yer typical lol

cheers guys

 

Salsa - yep. I snipped it off a little so it's not doing it as much now.

 

I like revs, what valvetrain are you going for to get those revs, and will the breathing cope - head work, cams etc.??

Sounds like a billet garret 35 going on?
?

 

Supertech Inconnel valves, Open the throat up on the heads a touch. Supertech valve springs & retainers. Crower stage 3 280/280 cams were my initial heartset but after a chat with Andy f it may well be a change to cosworth 278/274 cams.

I was looking intially at the gt30 for day to day drivability but to be honest I want the biggest as I'll always have that doubt set (what would it have been like to get the 35) so the rcm Rotated gt35 will suffice. oh & a syvecs 6gp
Winter project as I don't wanna go mad all at once as I have other jobs to do on the car too

 

Hi guys just thought i would let my fellow hatch owners know that a uk company called Nitron Suspension now make a kit for our hatches! its the first kit they have made for subarus and will undoubtably be the dogs!!! they have a awesome track record with lots of top race cars running there kit etc anyway they used my hatch to develop the kit so i have the first set! yayy lol so if your after a decent set of suspension check them out!

Thought I would post a few updated pics of my hatch



Over the last couple of days I have fitted some wind deflectors and a clear fog light lense





Also yesterday had anti lift kit and fast road geometry set up done, car feels a lot better for it, more planted on the road if you not what I mean.

 

Whats the next plan, get rid of those horrendus 2 pot brakes, that are fitted as std, how Subaru get away with them on the WRX's i don't know.
