The R35 injectors are 550-570cc, more then enough for my car. It's cheaper and plugs right in supposedly.
Yeah, they will do a break in on the engine dyno and the majority of the tuning/tweaking on there as well. Then the engine will go back inside of the car and get dynoed/tuned on Zcar's Dynojet. No more guessing what drivetrain loss is on my car anymore!
BTW, anybody knows what that red paste is on top of the valves?

That's one of the things I had read, plus just talking with some customers who have started playing around with the cars in depth
The finer the spray pattern, the better the overall atomization (more fuel molecules that can combust with air molecules). There are alot of things involved though - different injectors are designed with different fuel pumps in mind (different base pressures and volumes), so spray pattens can vary when one cars injector are used on a different car.
How critical it all gets in a relatively moderate compression NA setup I can't answer...at a certain point you can drive yourself nuts micromanaging this sort of thing.

Yeah, those inj are more than enough and still give you plenty to improve on motor-wise. For that paste, is it where the valve seats? (kinda hard to see the pic onmy phone) if yes, I think the red paste is like a way of checking the seal surface of the valves to the seats, Its just a way to make sure that they are seating correctly, my best guess. I'm no engine builder, but I have seen it before

Other then more frustration, nothing else is new.
The hold up is not related to my car at all. There is an engine on the dyno that they have been working on to resolve some issues and it's taking a lot longer then expected. So more waiting for me and the new ETA is now ........ mid Jan because of the delays and holidays.

I think I know what 1 of your new secret item is... New headers!!! Saw your post in the Stillen Headers thread. Are they long tube or similar design to the Tomeis just bigger diameters?
You don't think that your Tomei headers would be suffice enough?

Thanks Charles. Always good doing business with you.
I'll have a comp most likely of the Tomei with my new ones. We'll see which one will do better and yes the new ones are completely different from the Tomeis.
Most likely will sell them including the cams, if you are interested in the two let me know. I'll probably have them posted after the holidays. No pics of the new ones yet.

Unfortunately, no great updates on the car's engine as of the past four weeks. At least it finally made it to the bench dyno ... finally!!! Once you think it is getting close, more things come up to delay things even further and further. However, in the meantime I did purchase a few extra items for the car.
-Z1auto solid engine mount
-Z1auto urethane transmission mount
-Whiteline front urethane bushings all around
-Whiteline rear urethane bushings all around
-Whiteline rear subframe urethane bushings
-SPL front and rear camber kit
-SPL front and rear endlinks
-Greddy Infotouch Oil Pressure and Temperature adapter
-Greddy Oil Catch Can
-Project Kics R40 lugs
-50mm extended wheel studs
-10/15mm wheel spacers
Still need to pull the trigger on this, but most likely will
-Dual PLX wideband sensor
-PLX Kiwi Wifi
-iPod Touch 3rd Gen with Rev (to communicate with the Kiwi)
-PAC AAI-NIS2 adapter with iPod cable

Awesome stuff, in for results, mine is nearing completion as well.
I definitely understand when you say once it gets close, more things come up too haha. They just keep coming and coming .
