What size injectors do i need for a 20g turbo with external wastegate dump???

[98gsxawd]

I just got a 20g turbo with an external hks wastegate dump that was customized by turbonetics for me. I have 2 different size injectors will the evo 560cc or some denso 850cc work?? I have the 560cc installed right now so if those work ill just leave them on. I already have all the other supporting mods like safc,fmic,hard pipes, hks bov,injen intake, straight pipe exhauststronger internals from topline, eprom ecu...ect... So will the 560cc or the 850cc work or what size should i get... im a little new to this tuning but im getting there

Im looking to make 350 hp. So also what psi should i be setting it at to make 350hp??

regardless of your mods do you have a way to tune it, logger, ecmlink, 20g on 850s but do have a wideband no sense in all that if you blow your engine up. Get a wideband and some way to tune it.

Your gonna need to use those 850's and the SAFC will not compensate for them so you will need Ecmlink to compensate for them.

I am actually taking it to a shop here in San Diego called Reese tuning. They have a DSM link so im not worried about that just wanted to know what injectors would work better. What do u mean by wideband?? The air to fuel ratio??

 

[96WhiteTSi]

Yes the air to fuel ratio.. also known as a WBO2 or WIDE BAND O2...

Also.. the shop that has DSM LINK... cant just throw it in your car and tune it and take it back out.. its a "chip" so you would have to buy it from them or provide your own chip(dsmlink) and then yes they can tune it via their computer....

 

[92AWDHX40]

with link go as big as you want it will control them what are your long term goals? Wideband measures air fuel ratio. Get that next.

Thats not the gauge one huh...

will this one work?? INNOVATE 3796 LC-1 Wideband with DB Red Gauge - wbo2. I saw it on ebay for like 210 bucks..

... What do u mean by wideband?? The air to fuel ratio??

Wideband o2 logs Air to Fuel ratios. It is a sensor that you install in your exhaust stream that runs up to a gauge and gives you ACCURATE Air to Fuel ratios.

I know what you are saying but the OP may think an A/F gauge would suffice.
WIDEBAND O2... NOT TO BE CONFUSED WITH AN AIR/FUEL RATIO GAUGE ALSO KNOWN AS NARROWBAND WHICH LITERALLY DOES NOTHING.

YES, I LOVE my Innovate LC-1 Wideband. There is a vendor on ebay selling the kit for around $170 so I would jump on that deal. It is a steal considering I bought mine used for $150.

Ok so if i get that innovate LC-1 Wideband i can just install it and have the shop basically mess with it right?? Also is there anything else i will need to make the 20g work??
i have the hks bov, safc, fmic, hardpipes, exhaust, intake, eprom ecu, 255 walbro, tomei afpr, turbo timer, megan downpipe, 850cc injectors also some 950s now...will the 950cc be too much??

I have a 7 bolt... so im just trying to make 350 awhp so isnt 1200cc too much??? My 950cc wont work for 350??

850s should be fine no you need some way to tune your car logger or dsmlink. you cant just throw stuff on your car and expect to have it run the way you want. Get a tuning device.
