Congrats on home ownership!

Shops are awesome!

Do some more testing to insure the oil isn't getting past the seal.  Go back over the tune again with tony.  Then probably not much.


GF and I are about to be home owners so I have a shop to start putting together soon.

I wanted to run Desert Meihan at the end of the year but that has a small chance of happening.   Probably will just be a weekend show warrior for a little while before I dump serious money on drifting again.

That's awesome.
Now what's the plan?

Installed a shaft seal between the inner and outer distributor adapters shaft bearings.   Tried to get the timing puck cracked open and failed.   Drained maybe a little over a teaspoon worth of engine oil out through the harness hole.   

Since I disassembled the adapter at work, either I was correct in assembling it, or 180 degrees out.   Set timing based on several pictures in my phone.   Fired up and ran great.   So I'm somewhere + or - a few degrees of ideal. 

I noticed before screwing with timing that my car doesn't backfire on decel anymore.   Im assuming it's because the injectors are clean and firing on average 11% better.    Also fuel pressure is about 3-4lbs higher than it was tuned on.

Gonna have to do more testing to be sure, but I drove it for 15 minutes yesterday and it was back at full power and never missed once!

Rock Auto sells a GTS tank made by Spectre.  It's $130 shipped.  I did a review video on my you tube channel.  Overall quality is good and drops right in.   Then you could go GTS fuel pump bracket and any in-tank pump you'd like. (SR5 is mechanical fuel pump, so either way you have to adapt to a electric pump whether in-tank or in-line.)

As far as the throttle cable, I'm not 100% sure.  I'll text dan and ask him.   I'm thinking a GTS non cruise cable, which is longer, will work.  These can be bought brand new from Battle Garage-RS.

*Edit*.  Confirmed with Haymaker/Dan, OEM GTS cable works!

Technical / Sr20det swap question.

Hey guys, I just got my Sr wiring completed now I have some small stuff to figure out. In my research a while back, I remember coming across reading about using a throttle cable off of an older 240z. Any of you guys know which?

Also, I swapped the Sr into a SR5, did anyone here do the same? and did you use an electronic fuel pump?

I can adjust dwell.   

The AEM timing puck is two optical sensors on a wheel.  It has 23 small windows, and the 24th is longer so that both sensors read.    Essentially it's 24 Cam counts and 1 crank count per rotation.


Misfire showes up after about 2 minutes of driving, and gets progressively worse.   Usually it shows up as soon as I hit above 3,000.   Then it gets to the point it'll only idle.   The longer the engine is off, the better the misfire gets temporarily.

Well, it sounds like your fuel system has been completely gone thru, and with good compression numbers, that kinda only leaves spark issues causing the misfire.

Are the coilpacks still heating up?

Oil in the puck could definitely cause problems.

Is the puck just a single sensor?  on a cam?  no crank sensor?

Can you adjust dwell angle?

When does the misfire occur?

I have a scope...

I'm not 100% sure I found my issue, but I certainly found something not good.   My timing puck has been taking in oil!!

My theory:  oil pressure rises, pushing oil through the shaft bearings of the timing puck.   As oil saturates the internal timing wheels, it begins to start missing counts.   The higher the revs, the further oil is tracked up the timing wheels, resulting in more and more missed counts.   Of course in the AEM software it doesn't seem to indicate any timing errors, but that is likely because it's still reading the crank count inside the puck and attempting to correct itself
