So i've got a question about injecotors.

I went a bit furhter with my engine mods. Last time it did 80hp and 110nm.
Now swapped the 1.1 block for a 1.2 and done some more work to the head and fitted a thinner headgasket.

I read somewhere that the stock spi injector can only take about 80 hp.
And because my fuel pump also died i thought about doing it good this time.
So a 3 bar fuel pump, adjustable regulator.

Do you know if i can keep the stock injector or know of any upgrade?

Sounds about right with the 80hp. Just replacing it might be tricky, there is very few that fit plug and play I think (I once studied it in the turbo context). So upping the pressure is a solution, but (a) you have to check how much pressure the injector can take, (b) your ECU maps will get screwed up.

Edit: I'd look into what novitec mounted into the no 2nd injector turbo setup for SPI. Ask Mike of CCH

Thanks woj. already thought of upping the pressure.

I've hearde of a astra injector

I did find one thing.

Mangeti marelli made 3 types of spi injcetors.

Orange/yellow for 0.8 to 1.4cc
Green for 1.4 to 1.9cc
Black above 2liter

So now i have to find a 1.5 spi or bigger

I know the tipo / tempra 1.6 were Bosch spi would they fit the Webber throttle body?

I fitted a Astra 1.6 Spi injector , but it overfueled massively , and killed the hg

there is more out there ill look in to my list i had made , and ill post it up as i had CC size and every ting next to them

I wouldn't mind knowing this as well, been interested for a while at a bigger injector
