Currently got a set of greys to go in my build, people are saying 83's are better and flow more bhp?

What's the crack? Sorry if this is a repost, i did try searching... only mention i found was the spray pattern.

What will work better in my build?

Fully balanced bottom end Std crank and rods ARP'd
Wiseco 91.5 pistons
wrc HG
Turbosystems ported head
Turbosystems profile cams
AS Inlet
tubular manifold
CR T38
Twin air injectors
Wasted Spark

 

Although the Siemens 83lb injectors are larger than you require, I would certainly use them over the 403's for your setup. If everything is working to its maximum potential you could make up to 440bhp on your setup, and that is beyond the realistic flow limit of 403's. Not to mention the spray pattern and atomisation is far superior on the Siemens injectors.

Of course you will require the car live mapping on the Siemens 83's as they are too large an injector to risk an off the shelf chip.

Hope that helps.

 

Thanks for the info there Karl, is it worth looking at 55lbs or are they not big enough?

 

Speak to your mapper.

Being monday tomorrow i will. Just thought i would ask others opinions.

The next question is, if the decision is made to use 83lbs who has some stock.

 

Your turbo can flow more air than greys can keep up with. To make the most out of your engine I'd personally go with 83's. Only people that can't map 83's would say go with the greys.
