There will soon be an LSX kit released for the NC. In preparation for this project I have purchased a 2008 PRHT.

One unknown is regarding fuel delivery, and what changes will be needed with the NC fuel system to deliver the needed volume of fuel for the LSX motors (FYI they run at 58 psi).

Does anybody know the pressure and flow ratings of the stock pump?

Do you turbo/guys have to upgrade the OEM fuel pump? If so, what is the route taken (larger in tank primary, addition of secondary in-line, etc.)?

Anybody know if the stock pumps are the same for all 2006-2010 cars?

Does Mazda share this pump assembly between any different models (like the RX-8)?

Thanks,
Justin Wade

 

Bump. Looking for NC guys that may have updated the fuel pump.

Thanks,

Most modern fuel injection systems are 100ish psi. Our stock pumps (NA and NB) are fine up to that. They do fail, usually with age, and walbros cost roughly the same as stock.

Your problem is I can't name one person on this board with an NC.

 

That would be a difficulty if nobody on here has an NC. Unfortunately none of the NC guys running supercharger kits need more fuel volume than the stock NC pump can deliver so none of them knows. I was hoping there were a couple of homebrewed NC turbos out there.

Oh well, thanks,
Justin

 

Almost a year late, but we'll have a 265LPH drop-in fitment pump for the NC Miata fuel pump assembly.

 

^good to know. Just what I need.

Thanks,
Justin
