Mk1 white vts turbo .... 260bhp - 250 ft lbs

[gti180craig]

Yea I've noticed on these engines it's impossible to not have the downpipe near the alternator fantastic results though mate bet it feels like a different car

[robster247]

I have wrapped the downpipe and I'm going to make a cover of some description. Map needs a slight tweak at top end but he said it will be good for now

Next step is a set of 630cc injectors and go back to reach my goal off 300bhp .

Not bad for a diy build ...

Strange the duty is so high..

djx11b ran 491cc at 270bhp on a GT2554R
saxodaffy ran 398cc at 321bhp on a GT2871RS

Then theres the Lithuanian Saxo running 550bhp using 550cc injectors

As mentioned on facebook get some gold heat tape and wrap the wiring and alternator oh and a turbo blanket for temps!

That's what I'm using in mine , the Chinese shit ones though, probably a factor in it somewhere, will be going with the proper siemens 630cc injectors as they are only £200 which is cheap compared to the iwp069 poco ones

depends on the fuel pressure too.

Running 4 bar fp, I think you can go to 5 bar with these . But I'd rather do the job right and get the bigger injectors.

Plus after a long drive if I switch the car off then get back in it and try to start it , it goes on 3 cylinders for a while, so one of them is slightly buggered . Always comes back on but that's beside the point

Great results. I am aiming for the same power, I'd be more than happy with that.

djx11b ran a 4 bar FPR
saxodaffy ran a standard VTS FPR with uprated fuel pump
Lithuanian uses an adjustable FPR

e8_pqck ran 318bhp in an ax using 630 Siemens and 3 bar fpr



I think the issue you have is that they are Chinese injectors...


EDIT - I'm also still waiting for these videos and a new engine pic wouldn't go amiss (just don't upload to photobucket)

[welshpug]

please don't, its obvious they aren't great!

GTR injectors might be good for you, lots about as they get binned after about 600 bhp.

[robster247]

I will be throwing the injectors in the bin as one of them decides not to work when I switch it off and back on .

May get the go pro out this week and see what the quality is like .

Talk to me about the injectors from a gtr, are they a direct fit in the standard inlet ?

[blackie_2k5]

what injectors are you running? 440s should be plenty for the power you want at 4 bar?
