Hi All,

Just got back from Well Lane rolling road on what must be the hottest day in Batley this year!!

In FEB this year I clocked 318 bhp and 290 lbsft torque on a 96 UK Turbo with:

Full 2.5" system with decat
Blitz cone
HKS EVC3 running 19psi
HKS FCD
HKS AFR
Lightened pulleys
Iridium plugs

AMBIENT TEMP WAS 7 DEGREES

Since then fitted HKS Manifold, stainless uppipe and uprated fuel pump. Upped boost to 21.5psi.

Today:

Ran 331 bhp
but only 275 lbsft (down in peak but overall smoother curve)

AMBIENT TEMP 18 DEGREES

So, looking at the graphs, it would seem that the headers (and other mods) have cost me torque and power in the midrange but have given more at the top end.

I had also done several full power runs prior to this figure to check fuelling at the top end, so things were mad hot. If conditions had been the same as in Feb (10 degress less at least) I would hope for another 5-10bhp maybe.

The car showed near perfect fuelling (optimax and NF) with no leaning out anywhere and the operator commended the car on it's smooth delivery and progressiveness.

I have standard TD05 Turbo
standard ECU and standard internals and injectors.

My PAW figure was 255bhp @6506rpm.

I was kind of a guinea pig for the headers, in that i wasn't sure what to expect. I'd heard this and that but nothing quantifiable.
IMHO it's a lot of money to spend and you probably lose as much as you gain overall, but if you want top end power, they've worked for me.

Saving up now for an FMIC

Cheers

Did you heatwrap the headers?

TopCat

to really get the best of your mods at this stage you do need to make adjustments to your advance. not an expert but have experiance from own UKMY97 car 347bhp temp (18degree temp) 310 lbs of torque, 1.3 bar. hks zorst, ss dp, aps fmic, aps induc, 480 injec, fuel pump, ported headers not HKS, oh and LINK with shed loads of advance.

A friend of mine runs big dirty hks turbo, hks induc, front mount, hks evc 1.3 bar (my98 uk) get around 335 bhp, 289 on the torque.
Again no adjustment to advance.

make sense

Hi,

Downpipe and uppipe wrapped, but not the headers - yet.

Top cat,

Reckon you are right actually, torque should be above 300 really.
Must get a Link or similar I would say.

Cheers

Try and pick up an RA ECU. I was running similar spec/power to you but had 349lb-ft torque. It will run more advance than a UK.

Maybe even a WRX one would be worth a try ??

Hey Rich.....I have an RA ECU for sale from next week....

Evildead

RA?

mutant_matt

Rich,

The RA ECU won't work with the UK car, the wiring looms are different.

I would say that you could do with a mappable ECU (Link/Gems/Motec) and possibly bordering on needing a bigger Turbo and injectors too.....

Matt

RICH WILD

Cheers guys,

It looks like a Link or similar is the way forward.

Steve McCulloch has been telling me this for ages. Are there any good mappers for the Link in the North of England?

I'd better get talking nice to the missus.

Cheers

Rich i was at well lane on sunday with the 22b which ive just put hks headers on (wrapped) ive also got a hybrid turbo larger injectors fuel pump front mount and i made 324bhp and 340lbs ft i am on a gems ecu which i must say is excellent try speaking to jase at scoobymania about the gems. On sunday the ambient temp was well into the 20's. Also they ended up running my car 12 times as it kept losing grip on the rollers so probably lost power due to heat soak?

RICH WILD

Hi,

I remember you from the first rolling Road day I went on about 18 months ago. You were in Banzai too weren't you when CraigH did his 3.7 to 60?

That's one hell of a torque figure 340 lbsft. Just shows what those extra 0.2litres does. I see you've done quite a bit since that last RR day. Think you only had exhaust and induction kit then.

I ran loads too yesterday as we were checking the fuelling first before thae power runs. Temp was about 18-20 degrees.

I'm fancying an ECU change so I'll ask aboutthe GEMS system, cheers.

When the manifold is wrapped, I was worried that it would get very wet in the rain and start to steam a lot, smell, rot etc.
How have you found it?

Cheers

Rich

Mellow,

What ECU are u going to use ( I guess you are selling the original ECU of your STi ) ..... ?????

An early UK ecu is interchangeable with similar year Jap ecu, as would later year ecu, again matching similar years.. I have tried both MY94 WRX, MY93 RA, and of course my own MY92 UK legacy turbo ecu.
The RA was definately the pick of the 3, for my car. The wrx ecu made it go slower and was very quickly removed and thrown in the corner!!. Both jap ecus had the speed limiter, and I just stuck with my original legacy ecu. When the UK ecu was fitted to the impreza, the CAT warning light came on, although the car drove fine otherwise.
I would have kept the RA ecu other than this, as It was from mates car that got wrote off, and was being sold on. At that time, I had only just got my car, and knew very little about them ( over 4 years ago ) and didnt want to take any risks, as spares were a lot harder to get hold off than they are now.

steve McCulloch

From experience of myself and others I think you'll find that the Link is one of the better ecu's - dont want to go into the Pro's and cons...

We can have a chat on 30th. As Mo says -you must go for a mappable ECU. Bobs the only one that I would trust with the car.. down in Swindon. People drive from Portugal to come and see him - need I say more...

Darren Copper - you appearing on the 30th? - then we could compare!

Which front mount - a HKS?

dc911

Hi Steve i am running the pace front mount and have seen good results. When mapping the car the most we saw on a decent run was 27 degrees after running at full boost.
Rich the headers are wrapped and we have had some good downpours i havent noticed them getting wet and havent seen any steam or smelling. I am very impressed with the gems ecu and steve who maps it for scoobymania has got to be one of if not the best around.

pace fmic+hks manifold - you have to move the rad somewhat to get it fitted apparantly.

steve McCulloch

Darren

What boost were you running - and water injection? - I think you already had that though? as I recall - circular tank in boot? or was that another 22B owner

dc911

Steve i did have water injection but for some reason it stopped working when we changed to the gems will have to get it sorted.
I am running 1.4 bar until 5800 rpm then down to 1.2 bar to about 6750 then down to 1.1 bar.
What boost are you running ?

steve McCulloch

I'm running very similar - peaks at about 1.4 bar, but only holds about 1.2 bar at higher revs. So sounds about right...

It holds higher boost in 5th than 4th - dont understand the technical reasons why

I'm just waiting for RWilds Engine to go bang!!

Going for the ignition advance with Optimax and booster...( aided with the WI) - my water injection is on the car but not currently working.. - a little more work required. But then this is what most people are doing - all about getting the map right - at least your peak torque will come in much sooner than mine, with a 2.2 litre engine - should be coming on near full boost at 3000 - mine is just about hitting 0.8 bar at 4000!

Then once its all sorted it'll be time to get another car.... thats the usual thing that I do - just a shame that its taken me soooo long to get the car modified - should have stuck with the Cossie - less hassle and much cheaper to get power our of.
