My JDM Hawkeye STI

Well, Now I'm back to work and back off cloud 9 from picking the car up on Friday I thought it best to do abit of a thread to keep everything together and show any progress...

So here's my Decemeber 2005 JDM STI Twinscroll...It's had quite abit money thrown at it lately but the chaps business took a turn for the worst and he had to release some capital sharpish.... in comes me

So, This was the car on Friday when I arrived at the Subaru Specialist that RCM use when overbooked (hence RCM parts later mentioned)  


and then I lifted the bonnet...






Just kidding, that beauty belonged to this 900bhp beast!


Anyway, back to my car...
The spec is as follows
* Forged 2.0 block
* RCM LCM400 twinscroll turbo (also got the original in my garage)
* RCM Stainless-equal length manifolds
* RCM Uprated fuel pump... apparently the walbro ones are shite in comparison?
* RCM Decat
* 850cc Power Enterprise injectors
* Rota Alloys (fooking HUGE offset and stretched 225/40/18 tyres, clearly for aesthetics not practicality)
* Alcatek ECU with Anti-lag, Launch Control and 2 maps (Vpower/1.5bar and 95ron/1bar boost) mapped by Andrew Carr.




So a pretty good base car I think
Got home from the 300 trip, ears ringing from the exhaust and pockets alot lighter than 24 hours previously!!

Next morning I set about having my touch on it... first thing was to remove the soundsystem that had been put in using the highest grade wires I've ever seen... but then used shite amp/sub?!!

All the doors have Fusion speakers and tweeters in with crossovers, but I've just rewired them back into the OEM wiring...gone are those days... plus I can bearly hear with that 'exhaust' haha

After the above wiring nightmare, I set about installing my ATI/Defi hood and gauges. you'll notice these are completely unbranded, which I LOVE... I hate seeing gauges with multi colours, bollcoks signs all over, when I look at a gauge, that's all I want to say... markers and a needle - By chance I found these ones on Ebay years ago with my classic impreza, but they were nowhere to be seen this time round but after 3 hours (I kid you not) of trolling google/google images with god knows how many different words I eventually found them on a german website, no wonder they were good and accurate (mapped to 1.5bar)... german engineering     So I bought Oil Temp, Pressure and Boost (upto 3bar)


gave the car a clean, introduced my 9 year old to it...after calming down from a short show of 1.5bar in second gear with all four wheels struggling for traction on a private. perfectly safe road, he told me he can't wait to show his mates (yeah I'm THAT dad )
All I have to do now is hook up the oil gauges and i'm set.

one thing though, on these cold mornings, I have to give abit throttle on start up, not too much otherwise it splutters.... I have to let it idle for a minute before driving off or it coughs and splutters... after this said minute, everything is normal.... is this just because it's an aggressive map? or could it do with a tweek to its cold start? no smoke, pulls like a train!

I'll update this thread as and when there's changes

Lovely machine mate. I don't think the spluttering has anything to do with the map. My Hawkeye STI was running around 480bhp and it started first turn, every time without any erratic idling, spluttering even in sub-zero temps. I am sure one of the experts on here will be able to answer your question but have you checked the MAF as perhaps it just needs a good clean?

Personally I love the Rota Force alloys - but then I am biased as I had them on my own Hawkeye, although my stretch was only very slight - how wide are your rims? Mine were 9" with an ET35 offset

Very nice mate!!!

very nice car bud! your starting issue is probs because its maf less with running an alcatek ecu and would need alittle adjustment by your mapper

It's running mafless fella, if the engine is waem, even slightly it starts fine, it's only the first turn of the day  it seems, it was in a heated garage when I first seen it, engine completely stone cold and turned over straight away, battery is brand new, s'pose I should check sparks next... Of maybe 02sensor? Anybody ran a wide band in place of narrow?

That was my thought... Why is the map sensor not sorting it? 
There's been an air temp sensor installed on the IC...

Nice mate cant beat an early Xmas pressie

Lovely car fella,always fancied a white hawk would have to be the 2.0l though

I went to see a white UK sti and was ready to buy but then read about the engines being shite, which turned me to JDMs... I was going to import one but decided to go for this one

ive seen loads of alkatek simtek running mafless start funny my mates starts idles rough for about a min and then perfect make sure you dont put ya foot down when starting or before just let it start from the key because there is no maf you can flood them by pressing the accelerator

very nice mate ....

Very nice!

That looks really nice mate. The only other car I'd have from a red one is a white one

Very nice pal, can you stick a link up for the gauges you have?? I want similar, they look spot on.

Lovely that !! Mine runs ruff as fook till warm bobs looking at in January to sort it

thats a cool looking motor mate dont envy you when you,ve got to clean it altime

Is your ecu on the lastest software as you can have them updated now for approx £100, worth an ask.

John Shaky's car is awesome, really good build thread on it and going to be a time attack weapon.

Sure, They do 52mm (mine) and 60mm Think with the shite paypal conversion rate I got, I paid around £67 for all 3 and fittings delivered by DPD within 2 days....warning, they dont send you the rear bars to butt them up tight, thankfully my ATI/defi gauge pod was the exact diameter of the rear of gauges so I just push fitted them and they're tighter than a..... well.. really tight thing.

I'm 50/50 weather I should get Andy F down now or not, It wont start just off the key but if I give the throttle the TINIEST amount of push it fires up fine hmm... I want coilovers too....shop santa has a big sack!

Got a link to that thread? seeing the thing up close was truely awesome!!
The Alcatek ECU was only installed/mapped in June and the garage was the alcatek supplier (Christ Palmers auto services) so I guess it's got the best of everything...

COILOVERS.... MB Developments are selling some Tein super street coilovers on Ebay for £380 at the minute, without adjusters... reckong they're worth it?
I've been looking at BC coilovers - anyone got them? Scoobyworld can supply at OEM height/ready-gassed and with rear camber bolts for a fanny hair over £700.....

Matty is a nice bloke to deal with, very helpful and very reasonable. He breaks high end cars so is always getting new bits in so worth checking what he has in. I run BC coilovers, i quite like mine, they are mid range ones so are adjustable alleound, i run adjustable top mounts front and rear too.

Quite a few of the lads we race with dont like them/dont rate them and tend to use Bilstein, KW or EXE tc but its about the budget you have and what you expect them to do, i say for most purposes the BC's will see you right.

I had the BC BR series coilovers on my Hawkeye STI - bought from Scoobyworld with rear adjusters & ride height preset. Spot on with over 30 damper settings so the softest setting was close to OEM shocks.

These fecking wheels are catching if I sneeze too hard! 
Not to mention chewin the rear tyres 'sidewall'...
So I need coilovers for sure, but having just spunked out a lot of wedge for this, and christmas... I'd sooner spend £380 (adjuster spammers cheap?) + fitting, than £700+ plus fitting... If I wasn't going to need to replace them sharpish... I plan to win the lottery next week.

Fit them yourself to save you money bud, fairly simples to fit like if you have basic tool kit. Adjusting C spanners are cheap, some one on here may even have a set spare you can have to make do with,

I've got bcs on mine they are a good set up !! I had chew with rubbing but my car was dished too low... Get new wheels next week from Japan can't fooking wait

So many options, so little money haha 


JDM hawkeye sti 5 x 114 pcd yeah?

beautiful car you got there Aaron  
mines fitted with Bc Br with a 8.75 wide wheel with a 5 mm spacer, offset is 30  and i had to roll the arches but spot on now no rubbing at all,
