Good idea, also test to see if all coils are firing.
-
Could the Coil on plug not be firing and causing unburnt fuel?
-
That injector angle looks fine. Is there flow data entered into the ECU? 350cc seems big, but not crazy over the top. I doubt that is the issue.
-
Flow tested injectors? Then setup per cylinder injection till it's perfect? I have full sequential injection and setup each injector based off flow data.
-
I don't know his english is pretty hit or miss.

Mine actually flowed the best at .500 lift. 235. Interesting that his flows higher as lift goes up.

Ken is a great guy. I am stoked for his project. Question Cylinders 3/4 also seems to have the same shape and size as other cylinders. Why? Answer: This is to make the exhaust flow velocity uniform in all cylinders. In addition, a new water jacket is installed between the EX3 / 4 ports, which tend to accumulate heat, to make the head temperature between cylinders uniform. This is done to ensure the consistent exhaust flow velocity in all cylinders. In addition, a new water jacket is installed between EX 3 and 4 ports, which tend to accumulate heat, to make the head temperature between cylinders steady.

The casting quality and the effort that went to this head is just amazing.

Unless Mikuni starts remaking them (they should), prices will continue to rise.

So cool -
Yeah I was told to stay away from the Hanshin coils. I have the hitachi. The audi coils get used a lot in the Z world. Nice looking as well. The hitachis are around 50$ here. So it's fairly hard to beat price wise.
-
I hope you find them.

In testing the R35 coil came in 2nd against the coils they tested. No clue on the P100-T. The r35 coils are 40-50 each new.
-
Any data to back that up? Interesting looking coil
-
According to Platinum Racing a few other companies that have test the coils, the head are actually identical. The only thing that Nissan changed was the spring and boot length. Pretty common in the car world.

Stainless steel vs plated steel vs aluminum rivnuts
DuffyMahoney replied to fusion's topic in Body Kits & Paint
I have used all, all have downfalls. Are flares forever? Stainless is very very strong, I would most likely use aluminum in that aspect. -
Does that fit a smaller wheel? Nicely done!

I think I have all my kinks worked out. Finally time to road tune. FullSizeRender.mov

Twin cam head for the L6 from Derek at Datsunworks

What pistons are you using? -
My 2nd set of vintage SK throttles are just about done. Only think left is to come up with a tps solution. They are a gift to my 3.1L engine builder Andrew.

I decided to put the wiring down below, closer to the header:)

Well the day has finally come to use a heat shield. This is the one that came with my vintage SK ITB setup. How it installs originally didn’t protect my wiring to the firewall enough. So I shifted it down 2” and then slotted it. I hate the look of sheilds, but it was time.
-
I figured out all my issues. My fancy no contact tps sensor has this goofy huge 0 volt rest area. I had it clocked, but from 0-75% throttle the tps didn’t change at all. Then 75%-100% throttle it would move. So it would bounce .00-.15 volts and the ecu thought that was like 0-10% throttle. So clocked it 90 degrees. Starts around 2volts and goes to 4.3 volts. It’s super happy. Somehow this took forever to figure out. FullSizeRender.mov

Darn!
