Injector Q. Options

[BudmannG]

I am wanting to know what injectors came in the 2G turbo manuals. I was thinking they were the 510's, is this right. I also talked to someone that thought they were 450,s.
Could someone answer this for me?

As it stands right now I am running 450's in the 1G motor, which is stock. I am just curious to know if I am running the right injectors for this swap to a 2G. Thanks guys!

you pick injectors based on hp. there are numerous calculators available online, but I'd avoid going over an estimated 80% DC.

what hasn't been mentioned in this thread is a common tuning trick used in certain situations. depending on what tuning device you're using (SAFC, MAFT, hacked MAS vs. ITC, EMS) it may be wise to select larger injectors than you truly need or anticipate the need for in order to gain indirect control over timing.

however, if you're running 1000cc injectors on a 14b on pump gas you'll pretty much guarantee that in order to get the car even running in the realm of stoich, your timing curve will be far too aggressive. This is of course more true on a 1g than a 2g due to the more aggressive maps on the earlier generation.

But, using 650 or 720's on a 16G may be a wise decision if you've got good 93+ octane fuel and desire an aggressive tune.

On a full standalone, this point is effectively moot, as anything with incremental and separate timing control will allow far better control than the crude method described above.

Hope this helps.
