620's or 534's..injector opions please

[Royalty]

I have local guy selling some denso injectors.

He has some 620's and 534's. I dont have an SAFC , yet, but that wont stop me form buying them and just holding on to them.

My goal for my baby on the big 16G is a nice 12 at full weight, and possibly strip her down and shoot for an 11.

You can see my vechile specs in my profile, so my question is this which injector set should i get?

I know with the bigger injectors you get into the idiling problems and then an AFPR is required and i really dont want to get into all that.

i'd go with the 620cc since u have a built engine, your gonna need them with full boost on that big16g especially if u want to possibly run 11s, dont let your injectors be the only thing holding u back from going faster. i have 650s without afpr, with the maf translator, u could go that route, or safc , chip for the injectors if the ecu u have is an eprom ecu.

if the 620's are dark blue, they would actually be 660's. depending on what fuel pressure you run them at. sard, and i think greddy marketed those. i have them. as far as idle, the dead time on them is the same as the stock 450's, so they idle like stock. i would get those, then send them out and get them cleaned and flowed. www.cruzinperformance.com is a very good place, and very reasonable.

Whatever these "620's" are, those are the ones I suggest.

i didnt think about the maf-t.. how well would that work with my stock 1g bov?

i use the stock 1g bov vented to the atmosphere with my maf-t (blow thru setup) no problems, u can run it normally (draw-thru) put the gm maf in the stock maf location just keep your bov dump tube attached to recirculate the air. the base setting knob on the maft is for different injector setups it (affects the entire operating range and is generally used to match the translator and MAF to the new injector size.)-ramchargers maft
