Tuning bigger injector for spi

[qowaz]

hi,-

before posting my question, i'd like to introduce myself. my name is vasco, i'm 30 years old, passioned cento-freak and from germany. i visit this real good and impressive forum since a few months and found it while i was searching more technical iput about my engine. and i really have to say that the input i found here is hughe!! compared to the german fiat scene the uk one is really crazy!!! especially the turboconversions you make are great & often far beyond everything you can find here!! respect!!
now my question: i finally got all the parts i want to get out a little more power of my 1.1spi as there are: punto75 cam, a 36mm throttle body, chip from sjk germany and an open air filter set. all i miss for getting a nice finished and well running engine is a bigger injector for my magneti marelli spi. is nybody here beeing able to help me? where can i get one? are there other, bigger fiat spi engines wherefrom i could take one? hope to get answer soon!

thx a lot for spending your time,
greetz

You do not need a bigger injector with the modifications you have the std SPI is good for 80ish BHP

I would suggest you change the fuel filter and then maybe up the fuel pressure a little on the std regulator to accomadate the bigger TB
