Looking to move to TD05 on the above. Will STi 565 injectors be enough (with fuel pump, reg etc)? I presume these should be a straight swap with no mods necessary?

LoFi

 

I was quite on the same way : VF34, Walbro fuel pump, STI 505cc injectors.

Though the ECUTEK vendor don't remap MY01 with STI injectors...

Be carefull...

I think you must keep the stock rings (gaskets ?)
(Read this on Nasioc...)

 

Well, I know RB5Scott got 380 odd bhp on two different rollers using STi7 injectors with a TD05 (Garrett wheeled hybrid). After changing his headers, and remapping by Pat, he may well have been making over 400, but melted a piston before he could prove it. Based on that, I'd say they're OK unless you're after really silly power.

 

Ive been told to keep with my stock injectors and use a bigger turbo and to keep it like that as the ecu tek aint good enough to map new injectors ( or go motec) or it will become less driveable ie lumpy - this is buy the guy who mapped my my02 (powerstation- can not knock his work so far, the car is far smoother than it was standard)

but then I got told by TSL it would be fine so Im not sure who to belive

I was going to ask the question when I had the money

I will quote myself from another forum :

The first thing to be sure : are the MY01 injectors 380cc or 440 ?
It seems there's a debat on this topic.

I can quote a dozen a ECUTEK remap in the U.S. with stage 2.5 (including VF turbo, Fuel Pump and bigger injectors)

 

???

The car could run absolutely wonderfull even with 740 cc injectors after remapping with EcuTek tools!

Mark.

 

WRX_Rich : Which mapper are you talking about ?

Perhaps, it's the same one for me ?

P.E. ?

 

it was powerstation... so if the ecu tek is so good why do all the big power guys move to motec, gems etc

as stated before I can't belive how my wrx drives after he mapped it's so smooth and bags of power - I ve heard that some people say after a ecu tek it became lumpy, but this is the opposite with mine, so I do trust what he says

 

Well, now I'm less sure

Bob Rawle has recommended 550 injectors along with either TD05 or VF23 for the sort of power I'm looking for, which is very modest. I am sure Pat had told me that the ECU is quite capable of adapting to larger injectors on its own and I've also read that after an injector change the fuel consumption goes up for a bit and then settles down, with no remapping. So god knows.

I was looking at getting the injectors from the US as they seem quite cheap. Anyone know if there are likely to be any differences?

I suggest you read this http://forums.nasioc.com/forums/showthread.php?s=&threadid=478921

then get your dremel out.

Tweaking the stocker is a cheap (good) way to add more fuel, but without a good maper (who agrees to map non-stock injectors)behind the laptop, it's useless !

Though spending $400 for brand new STI 505cc, is useless too !

A good friend of mine was running with stock fuel pump, stock fuel rail, stock FPR and a big Apexi 20g and he got 335ch on the rollers :-) with Apex'i AVC-R and S-AFC !

That was b4 fitting a full decat 3" titanium HKS...
So it's not impossible, but what about reliability ?

Quote directly from Ecutek Website :

http://www.ecutek.com/tuning/injectors/

So what size for MY01 : 380 or 440 ?

I would like to have a real answer directly from the people involved...

Oh god Pavlo thats not my cup of tea at all. I don't even know where the injectors are let alone have the want to fiddle about with them

Will the Sti pink injectors do me 565cc from the US or should I wait around and and pick some up from the UK. Any confirmation as to whether a remap just to run the uprated injectors, fuel pump and regulator is required?

LoFi

 

I made a topic on Ecutek Forum, where gurus will certainly give us the answers :

Hope this help.

 

I had a reply from Stephen Done himself :

I hope it's that !

I'm still waiting PE answer to my email !

 

Of course you can remap for new injectors with EcuTek tools! While the newer software makes it seem easier on the face of it, it is likely whatever model year will require considerable tweaking as spray patterns seem to change too.....and it's not linear (especially if changing fuel pressure or regulator at same time), so global map changes don't cut it.

Bob Rawle had absolutely no problems EcuTeK mapping my MY02 bugeye with TD05, sti Injectors, Uprated pump and regulator etc..... I went for safety and future possible mods with choosing bigger injectors rather than maxing out the originals.

Midlife.....

 

Midlife - so you went for the Sti 500cc top feed injectors? Or did you add more room for further mods and go for 640s? Sounds like you've been down the TD05 FE route? Wouldn't mind some pointers on suppliers/fitters if you have time, by email if you like.

I've got to use my car every day come rain / shine / snow. It also goes to ASDA with the kids in the back at times so needs to be reliable. I went the Bigger TMIC, Bigger injector, fuel pump, reg , TDo5 and "Guru Bob" TeK 3 route to give me safety and a bit of leeway if I wanted to add a few more bits. I tended to stay with people I had heard of to supply bits.......

TD05 front entry from Andy Forrest

Sti Injectors (505cc I think) and fuel pump etc from Mark Aigin at Lateral Performance

Sti Top mount from my very friendly scooby dealer Stan Palmer

Various bits (Samco hoses etc) from Jamie Whitworth at JW racing

Not the cheapest way of doing it by a long way I guess but everything arrived on time

Midlife.....

 

i just got 326 bhp @ g force with sti 7 injectors fitted

 

I have my old set of sti7 injectors for sale! They were only in the car for 6months and barely covered 3000miles!

They will make 400bhp easily on a fuel pressure regulator!

Lofi

I have to agree that I have been told that the STi7 pink injectors are good for at least 350 BHP with supporting mods.

I got mine brand spanking new in the plastic wrappers the next day delivery at £517......not cheap

Midlife.....

 

Scott - very interested in the injectors, how much do you want for them, email me

Midlife, sounds like you have gone exactly the route I have mapped out for my car. Getting the larger top mount is proving the most difficult at the moment. How much was the new one you picked up? Did you also have the 3-port boost solenoid fitted that Bob recommends? Thanks for the info

LoFi

 

Hi Lofi,

Can't get your e-mail address! I want £350 for them. like Midlife i paid well over £500 for them.

Scott

 

LoFi,

STI 565 Injectors available from Extreme PSI in the US (www.extremepsi.com)
Price is 390 dollar + 30 dollars delivery which works out at 300quid with all the taxes and vat paid.
Mine arrived a couple of weeks ago
Hope this helps
Martin

 

The pink STI injectors are 500cc

 

Lofi

Deep breath....the cost of a new Sti 7 top mount was about £500 ish Plus VAT including the metal Y piece to convert the WRX to the Sti. I couldn't get one from Grade A, Scoobynet or e-bay at the time. I did go for the 3 port solenoid.

Midlife.....

PS I think my pink injectors are 505cc

 

Scott, sounds good email me further details, age, use etc to :

pierslofi@dsl.pipex.com

Midlife - yeah I'm on the hunt on ebay but I'll try grade A as well, not in a real hurry although would like it sort for my run to Le Mans in June. Where did you have it all fitted?

LoFi

 

I've just pick my 4 STI505cc from a mate who ordered them by mistake.
Got them for 350€ circa £241
Also got the walbro 255lph fuel pump for 108€ / £75 & the VF34 for 845€ / £582
Got all from Gruppe-S
For a better TMIC, I wouldn't buy a STI ! I'd rather go for the Hyperflow : $800 + shipping / taxes

Anyone knows if Power Engineering are on holidays ?
I still don't know if they will remap my car ...

 

Sounds like you've picked up a load of great bargains there.

Why not an STi IC? I only want to go for top mount and I won't buy a new one. Now I've seen the Hypreflow site and their top mount, I'm starting to drule

LoFi

 

The STI TMIC brand new is quoted $625 + Y piping $150 = $775

For $25 more, the Hyperflow if bigger, better and has more efficency, due to his less pressure drop.
Stock intercoolers are known to have up to 3psi pressure drop and aftermarket (Hyperflow, APS, MRT, etc) only 1psi !

DROOOOOOOOOOOOOOOLLLLLLLLLLLLLLLLL ! ! ! :-)
