I've a Sierra dohc converted to 16v using Scorpio head and also turbed it. Injectors are side feed and is not easy to find good options as with top feed ones. I've tried injectors from skyline (around 370-390cc) but they are not big enough for my boost. Now I'm using injectors from 2.9 24v Bob (removing caps they convert to more than 500cc), but again not enough flow.

I want to convert it to top feed injectors. As now there are new Bosch options not very expensive. I can buy new 1000cc ones for not a lot of money, making me capable of more boost and e85.

Anybody now if there are any engine fuel rail than can fit mine? Rs2000 Scorpio have the same head but again side feed injectors.
