325i turbo

roughly speaking, how much should the timing be retarded on boost?

[dirtydog100]

what injectors do you recomend?

at least 440cc injectors.

It´s got nothing to do with boost but airflow , and since airflow is different between various turbos at the same boost it´s not possible to say.

oh right ok, where is the best place to find those injectors?can i get them from a different car?
only reason i asked about the timing is because a mate of mine reckons he can build me a chip that will retard the timing by say 6 degrees to allow for boost. bit crude i guess but would it work?

Get a piggyback to do it and you can have control over timing depending on boost.

EDIT.

42lb injectors can be had from V8 mustangs and other Fords.

42lbs/hr also lurk in rover 620 and 820 turbo's and MG ZT-T iirc ( mustang V8 )

chip to suit a turbo is possible but how do you propose getting the motronic to "see" the boost ? retarding timing beyond peak N/A torque will net you a result but this is a critical area and not one where £££ can be saved I'm afraid dude.

cool, thanks for your info there guys. im concentrating on my carb'd one for the time being but will be starting the turbo one in the following months. thanks alot
