Twin s366's injectors?
 

SBE LQ4
Twin S366
Custom cam .600+ lift
Microsquirt3
110 race fuel
MagnaFuel 4303 -10an feed
Truck manifold and rails

Siemens deka 80's going to be enough?

Just go with the Bosch 210s and be done

210's for race fuel haha He's gonna need a new block and heads to handle all the injector.

Depends how much boost/power you aim to make.

They could very easily be enough, or not a fucking chance lol

Can't use the 210s on the Micro.

Looking to make 800-900 RWHP on 20-25#'s

Magnafuel 4303 and 80's should get you there on race fuel. They are rated 845cc at 43.5PSI but if you need more then raise your base pressure, I normally start at 58PSI where they are flowing closer to 1000cc.

You should be fine at that sort of level. You probably wouldnt get much more from them though.

What would be the next step up that would work with MS3? I have to buy them anyway and wouldn't it make sense to go as large as I can get away with with room to grow?

You can get high impedance injectors up to around 2000cc. Larger injectors can get more tricky if the ecu you are using cannot do full sequential...so no idea whether you are doing that or not.

But you can get all number of sizes from 800cc right up to 2000c, just whatever you want really.
Some are pricier than others though, but it is worth getting good injectors. They're kind of important to your engine, but also factor in some can be fussy on fuel type so ensure whatever you buy is compatible with the fuel you are using..

Most appreciated Stevie. I'm new to all the FI and EFI crap, so tough to get up to speed while not shooting myself in the foot. All on a budget too.

Any preferences that you know will work, let me know. You and this board have been very helpful.

Really best to call an injector sales place local to you and discuss.

Personally I'd prefer ASNU for bigger stuff, but some like ID, FIC, etc etc

I have a very similar combo , forged 370 and twin s366's
i use twin xspower 44mm gates
as for injectors I went with fic 127lb/hr
I'm running 93/ water meth
my fuel system consists of a stock 3/8 feed and 340lph in tank pump
a secondary 6an feed with a 380lph inline pump, both y together and enter each rail at the back of the intake, front rails are connected by my boost referenced regulator , and return back too the tank.

I plan on twin precision 40 gates and a 60 bov. Should be enough to control boost, yes?

Do you run a truck intake? What engine management? What power your making? Any links to your build? Very interested.
Thanks

I have been considering these injectors. Are these a modified unit? I am very particular about idle quality and driveability as I tune a lot of vehicles on the side. I am also running a forged 5.3 so injector pulsewidth will be lower. When you get near min pulsewidth the fuel delivered per shot has a higher variance (higher standard deviation) and this results in erratic and unrepeatable behavior. This goes back to the infamous "dynamically matched" injectors fro ID. It really does make a difference if you care as much as I do about this part of the tune.

How have these injectors worked out for you? Which engine management system do you have and was the injector data acceptable as a drop in set of parameters or did they need adjustment? Thanks for your feedback.

Another quick question. Twin 38mm, 40mm, or 44mm waste gates to control boost? Looking at:
Tial
TurboSmart
Precision
JGS

I've Precision 46's, fine after 3 years.

Will 2 38's be enough gate for s366's on a 6.0?

turbosmart has surpassed tial in my opinion.

Depends how well it's plumbed and how low you want boost to go.
