Thinking about fitting 555 injectors but do i have, my ecu remapped and will these work without blowing standard tubs and inner's of my engine!!!

You'll need a chip to stop over fuelling.

If remapped with chip would this bring any more Bhp? Or is it worth forgetting?

With a remap, injectors and air filter you will get a decent gain but I'm sure someone will be along soon to confirm

running 555's will able you to run the oem turbos to full boost but old turbos and engine + high boost = bang ;)

I'll forget that then! Thanks for info!!!

Is it not safe with a small boost increase then rather than a full on increase?

What make injectors do you have matey?

 

Al.

you will need a remap but will gain some decent power and internals and tubs will be fine as long as they are in good working order with no problems.

what i mean is with oem injectors you will run say 14 or 15 psi and the bottom end seems to handle that ok for a good while but you stick 555's in and you are going to want to run even higher boost so all its going to do is put even more strain on an already ageing bottom end ;) i just cant see the point of going to all that trouble for 2 or 3 extra psi :)

Thanks for clearing that up, I've read about so many people running 555's on standard engines with no problems got confused as to why it could be a problem. Glad I have a fresh rebuild then with 740's !!
