Bosch green top injectors

[dich]

I bought a kkk k27 turbo for my s2 3b.Now I search for the appropitate injectors.My decisson are the bosch green top injectors or so called Ford green injectors 440 ccm.The question is whete to buy them from.I found some at good price http://rs-power-shop.com/product_inf...370a4af86260b1 . After that i found them at even better price http://www.aliexpress.com/product-gs...olesalers.html .Are all injectors chinese ones? Are there any originals?Do the chinese ones work well.I will be glad to hear you suggestions.

i would avoid any chinese replica parts - have heard lots of bad stories about poor performance from such injectors. AFAIK they are NLA from Bosch, but you will find some reputable injector specialists in US and UK selling refurbished originals.

The other questionable activity is loading up all the torque from a K26/27 into a 3B and hoping/praying that spark hop inside the distributor does not destroy your engine.... A little extra money for coil packs, ECU and some wiring tweaks gets you away from that situation.

Second link is 100% chinese, they don't work, car won't even idle, never mind driving.
First link don't know, might be genuine, might be not.

Best to buy Volvo injectors, 0280155968, they are also 440cc (but different latency), need different mapping.

So I am a little confused.Where I should buy them from?Is this good

Yea, five-o is good.
You still will need someone to map your car for the injectors though.

And if your turbo is a full K27, not K26/K27, then those injectors will be too small.

This is the turbo http://cgi.ebay.de/kkk-turbolader-K2...item27bc2d7649. I think it's k27/27.And 440 cc injectors on 3 bar will be enough for 400 crank horse power.Am I right?

[prj]

At 3 bar? No way.
At 4 bar they will be enough for 400-430 hp.

But to get that amount of power out of it you need it properly mapped.
Considering your last post here:

I don't see that happening

The problem with the mapping was solved.The fuel pump was not working corretly and fuel pressure was dropping.At the moment the car is boostign normally with wastegate spring set to stock.Is this good for 3 bar fuel pressure http://rs-power-shop.com/product_inf...370a4af86260b1 .

[prj]

Fuel pump was not working correctly and pressure was dropping, yet you had 10.5 AFR?
Right

About those injectors - no idea, never used them.
If they are not chinese replicas, they will probably work.

Right

Yes there is no logic for rich mixture in high revs and dropping fuel pressure.They also told me that there was a difference between the map and the new 250 kpa map sensor.After that the car was running normally.

[prj]

You should listen less to what people tell you, when you can see it defies logic.

Fit a FPR from 7A engine and use 440cc Volvo's.

Thanks for the advices.I will get the volvo injectors.

Agreed, stay away from Chinese stuff

Find some used ones on ebay and then get them professionally cleaned/serviced

USRT sell the genuine article Bosch 440cc injectors, $300 a set and I can't remember what that was shipped. I think it worked out about £220 when i almost bought a set, assuming you don't get hit for import duty.
