So injectors are not recommended? I read before 300zx TT injectors are a good upgrade as well.

I think you need to perhaps read this thread again...and again like I said earlier.... The point is not being taken.
The facts.
370cc injectors are far too large for a 3.0L normally aspirated (N/A)
The reason we state adding more fuel is because w/ an AFC, you can take out fuel, thus adding timing indirectly ... But since the injectors are larger or the FP higher, you will not go lean when taking out the said fuel.
Our vote is for a AFPR, since it is cheaper and will accomplish the same task.

What's the deal with the modified SR20 units? I hadn't heard of this...
All the reasons in the world for an NA car to go AFPR instead of injectors.

Well I sent out my FPR to get converted. If all goes well ill contact him about us, so anyone can get one for $40 shipped OR IIRC $25 if you send the guy yours. The thing is he needs cores, and I sent him 5 SR ones, 2 of which should fit the VQ. I think im going to have both of them made in to adjustables. He sells them pretty quick too so we'll see.

What amount of additional pressure is everyone/anyone at? i saw .5bar but was wondering if theres anything else anyone is at

I always have.
A32 DE/33DEK 3.0L = 3.0 Bar, 3.5L = 3.5 Bar.
SR20DEN bumped the imortant threads a few months back... it shouldn't have to be done again...

I gave him stock FP's...
The other question has not been answered in full just yet. (i.e X FP gives Y timing advance, or X injector 335cc/370cc
gives Y timing advance)

are any of these what I'm looking for?

or is there a better brand?

Not many people have ran + PSI on an A33B that I know about.
There's not a known FP to 'shoot' for. It's all trial and error, try this try that, monitor it and see if the pump holds even @ high RPM.
There are a few DEK owners running a tad more but some tend to lose some pressure @ high RPM's...
If you( A33B person) can get some DEK or Z33 injectors for cheap on here or my350z.com... that could be an alternate route as well.

nmex, to use DE-K injectors wouldnt you have to modify the injector harness? if the problem is fuel pressure tapering at higher RPMs, would it be possible to install a second pump, inline as a booster? i know that would be a pain and probly pointless, but possible?

I don't know if this is what you're asking for, but back when I had a fuel injector test setup, I tested the stock VQ30DE injectors at over 160 psi with no problems. I forget what fuel pump I used to do that with. My stock fuel pump was good for only about 65 psi.
