interesting, are the Porsche inectors a straight fit or did you need some fab work and are the high or low imp?
sorry for the highjack

They are low impedance and not a straight fit.
Although, it was very easy to modify them on lathe. Stock head, stock fuel rail and FRP. And they are grey

taken from another forum;

early bigport 4age's are 220cc @ 48psi (blue top), low ohm
later bigport 4age's are like 240cc @ 48psi (tan), low ohm
smallport 4age's are 250cc @ 48psi, high ohm
silvertop and blacktop use the same (side feed) are 270cc @ 48psi, high ohm
4agze is reddish and 365cc @ 48psi

The bigport injectors are bigger than I thought! :S

Bigger ?

High reving 1.6 engine like 4AGE should use way above 200cc.

Stock starlet gt/glanza (4efte) injectors are 295cc high imp. (Just for reference). No mods needed to fit.

The bleu injectors from your swiss MAF Hachi are 210cc low-imp injectors.
On the bleutop you also ave the grey like the one that patrik show us and it's are 182cc low-imp

On the redtop Map you can have pink one that are 200cc low-imp

On the redtop hi-comp (small port) it's are green and are 250cc hi-imp

Huh.. could be.
I allways found info of ~185cc so i concluded mine blue are that size.
Could be that they are bigger.

btw. what is default fuel pressure. around 2.7 bar, 36psi ?
