I've got a 2005 WRX Wagon which I've maxed out on the 380 injectors at 279/301 with a standard TD04.

I'm going to fit a hybrid TD04 to increase the power higher in the revs and was going to fit 550's but have just seen Matty's got some 440 available and they are a lot cheaper than the 550's.

What do you think the 440's would get me too? I'd be happy with around 310/310 a long as the power pulled all the way to the red line.

I was going to ask Bob Rawle but don't want to both him..... yet

 

Thought the std injectors were 440's? Light blue end feeds?
I'm using hawk dark blues 565cc 88% duty cycle at 350hp

 

as above, should have plenty of headroom on the injectors. Check the pump isn't struggling.

how do you know the injectors are maxed anyway?

 

Thanks for the quick reply's guys.

The wagons have 380's its the saloons that have 440's.

Bob said they were maxed out, I have already uprated the fuel pump.

 

I have a set of std blob wrx blue 440's here (removed due to upgrading to 565's) you can have them for cheap if need be.
£20 plus postage. They are no use to me.

 

fair do's, didn't realise wagons were different.

second hand set of 440's will be cheap enough or fpr

 

as if by magic,,,, hahaha

 

I don't want the smelly little buggers!

 

Cheers boosted.

I'll double check with Bob and get back to you.

 

my 03 wagon made 320hp using a VF34 on the standard injectors, but they were maxed then.
Is your's the 2.5?

No mines the 2.0

Are you definitely on the original injectors?

 

this was about 6 or 7 years ago but yes definitely on the standards. I thought the wagon had the same injectors as the saloon!
I had a 3"miltek exhaust at the time and later upgraded the top mount and fitted 550pinks and got a bit more.

I've just sent an Email to Bob to check.

thanks again

 

personally if they're out of a standard blobeye wrx I would count on them being the same injector, called 380 or 440, I'm sure it's all about what different people rate them at if I'm not mistaken.
The 550 was always the next upgrade and if Bob say's they're maxed a wise man wouldn't second guess that

 

Just had a chat with Bob. Change of plan now, going for 550's

Thanks guys

 

Reef, and anyone interested, a crude flavor of what the injectors will give at different fuel pressures

440Injectors
320hp - 3bar Fuel pressure
346hp - 3.5bar Fuel presuure

550Injectors
400 - 3bar Fuel pressure
432 - 3.5bar Fuel presuure

 

Hi there

440cc injectors should be on wagon too,as we have too 440cc injectors as standard on our wagon,they should be blue(light blue) if you have them,then they're 440cc and with reflowing,you should have 740cc injectors which should be OK up to 500bhp easily,we are run them at 490bhp plus NOS@2.1 bar fuel pressure,with more fuel pressure I would say 520-550bhp is possible

550 are probably next step for every WRX owner when he wants more power

Hope this helps

Thanks,Jura

 

Thanks guys.

I don't know where I got the 380cc idea from but thanks for confirmation. I'll check under the bonnet today.

 

Ok, checked mine and they are light blue so must be 440's. I've not no idea where I got the 380 story from......

I think I'll bolt on a VF35 and see what Bob can get out of it

 

I've got a vf35 and a set of pinks for sale

 

Thanks Pete. I've just secured a VF34 (thanks Rich) but let me know how much you want for the 550's.

Dave

 

Interested to follow this as I have a hybridised TD04 waiting to go on my wagon, plus a decat up pipe, and some new coil packs that Martyn at Enginetuner recommended . Just looking for some pinks myself, if anyone has some

 

Hi there

I've got for sale reflowed 740cc injectors,which has been reflowed and decapped just recently,not sure if you are really need such big injectors

Hope this helps

Thanks,Jura

 

Great turbo ! should get enough out of a 34 with 440's tbh. On the basis that my flow matched 440's are c.320 (TD0516g)on Ph2 classic 440's. I imagine the newage 440's are better technology. Always cheapest to get a set of 440's and get them flow matched and modified to flow higher by Lateral than shell out for 550's

 

for my good set of pink 550's £120 plus some post

 

That's where I am at the moment. Do I bung the VF34 on and get it mapped and see what the drivability and power is like or do I hang on buy some 550's and an STI top mount and then get it mapped?

 

Depends on what the mapper charges for an upgrade tweak really. But yeah the TMIC and Injectors are going to make it easier to extract the 34 to a good figure

 

Cheers, that's the conclusion I'm coming too. Just need to get the cash together for the other parts.
