Big turbo/fueling/mapping?
« on: 11 January 2013, 20:13 »
Ive got a Agu and im getting it sorted to run a big turbo, at the mo ive got the standard injectors on along with the standard sized diameter maf housing.

My question, can I put on the bigger injectors as long as I scale up the maf diameter as well? can the ecu take that into account and run ok? or should I wait until the tuners fit them?

Ideally id like to fit them both now but dont want to do damage and get bore wash or anything like that as the engine has now only done about 100 miles since rebuild and slowly breaking it in to get mapped.

I read somewhere that if you kept the proportions right with MAF housing and injectors, it was relatively safe to do, however going from 2.5 ID to 2.75 ID (vr6 housing) doesn't give you much scope for larger injectors anyway, until it's mapped of course.

I read that some where as well which is why I'm asking, ive got a 3.25 intake and either 440 bosch and adjustable fpr or siemens 630, to get the max out of the setup

But as dave said if you keep in the scale between them both is it ok?

I believe it is as they correct themselves out, aslong as you could get them pretty damn close, I think you'll be OK.
