Misfire After Tune Rb20det R32 Pfc

[R31Nismoid]

For 215rwkw the 255lph walbro is sufficient.....

I mean if its standing up to 85psi base pressure and still flowing enough for it not lean out at 215rwkw that has to count for something!!!

How long will it last???? Thats another question

Well no - Walbro's are flaky under higher pressures. I've seen my own car with 240rwkw be perfectly fine with a walbro.

Up the boost to over 20psi and edge to 300rwkw and all of a sudden it gives out intermittently. Dropped a bosch in there, AFR's went into the 10s immediately.

Sign of something not upto the task. Basically it comes down to risk. Are you going to risk a motor for a $230 part? Come on, that is downright sillyness.

agree with ash

also note wallbro rated on 15.somethingv - it wont get 15v in your skyline

ie it will flow less

but as the others have said

its a risk and a decent risk, if the pump cant keep up

or struggles to flow enough - the engine will lean out (it wont stall) and probably go bang from excessive heat as its lean

Will u run your $100000 rb26, t51R, 1000cc blah blah with a 044 bosch???? I don't think so...

Even the 044 will run out of flow at some point but that does not means it is shit.

no... i'd run it with 4 bosch 044's.
