I've got a Brand new not broken in S4/5 TII engine.
It's got S4 rotors so it's lower compression.

It's got everything else S5(Manifolds/Turbo).

My question is will my 550 injectors keep ups with my mods below? I just had them cleaned and flow tested too.

2 are a 5500 1350 series and the other 2 5500 1370 which flowed an estimated 1-2% more than the 1350's.

I have Racing beat Down pipe to Presilencer(no cat) then Cork sport 2.5 to 3 inch single exhaust.

I've ported the wastegate and have a Walbro ready for the car.

I'm going to use the stock TID until I can fab up one.

Do you think my 550's will hold up pretty well? Any idea of what boost I might see?

 

my car runs fine on stock injectors, just get a boost controler or something you can monitor your injectors.

 

Geeeeez. You've got two 460cc injectors in your car??? Your words above say so. What did you think the 1350 were/?????? Ain't 550's for sure.

 

ya dude, all the injectors should be the same. with stock intake and ported wastegate, you should be fine with stock injectors.

basically you have a stock motor with exhaust and ported wastegate. without turning the boost back up, you probably aren't seeing anywhere near the limit of the injectors.
