M3 Fuel Injectors.

[catalyst.]

compatible with my 325i m50b25?

flow is 24# per hour if im not mistaken. ive heard this is a decent upgrade over the stock ones? any truth to this?

also.. m52 intake manifold would this be a decent upgrade over the m50? ive heard its compatable. any significant performance increasE?

gawd so many mods so little time...and money

I'm pretty sure it wouldnt be that great up an upgrade... your still going to be pumping the same amount of fuel... and your still going to have the same fuel pressure regulator which will only allow as much as the drop in pressure of your intake manifold.

Not to mention your fuel map will not change within your ECU.

If you want to get the best out of larger injectors.... you must either upgrade your intake manifold with new software included which will change your fuel mapping.... (Jim Conforti makes a good one)

In a perfect world you could run a independent fuel system... with a larger output pump... larger injectors... and a better manifold thus giving you a lot better power curves and more power.

Good Luck,

Les

Yup. To benefit from more fuel, you would have to have more air as well. A big ole' CAI, MAF, and intake would take advantage of 24#s/hr from the ///M injectors.

no, m50 manifold is better than m52. the older obd-i manifold (m50) is less restrictive. many obd-ii m3 peeps toss their m52 manifold for the m50. this is best coupled with intake & 3.5" MAF.

air to fuel ratio..... just injectors would be a waste...
