Project 24

[murrayis]

Well the holidays are over and it's back to work tomorrow with this in mind I headed around the corner to my local autobarn and picked up a new ring compressor

All installed:

A few people have messaged me regarding the utilization of ca18 pistons and the deck height; well here it is and the deck wasn't adjusted

The dial guage says they sit about 1 thou proud of the deck surface.

Hope you guys like the updates!

Picture 3.

Is one of your pistons the wrong way around?

Just the valve relielfs look wrong opposite to each other.....left piston valve notches on the upper side in the pic come close to the edge compared to the bottom notches, piston on the right is the opposite orinatation.

If the top of the pic is the passager/hot side, id say the left piston needs to be spun 180 degrees.

Or am i just going blind in my old age?

I'll have to check it out they stated the writing is the ex side.

That is a good f**king spot, it is stuff like this that makes me so nervous about ever considering building my own engine, even if it does state the writing is on exhaust side, it is completely plausible that they stuffed it up.

[murrayis]

Hmm You may been correct! two of the pistons were ordered outside the set of 4 for obvious reasons a CA18 only has 4 in the set.

Very good Spot.

All I noticed on that pic was your big toe is heaps shorter than your second toe!

[murrayis]

Lol indeed

[murrayis]

All fixed

[GTScotT]

You didn't cut your toe did you? Was it back to front in the end?

[murrayis]

yep switched it around

[Manuel Kasko]

Interesting read

Keep up the updates and good spot as well lol

[murrayis]

Quick update.

Tomei head gasket arrived this week and today ive bolted down the head ans should have it all back together this week fingers crossed!

[murrayis]

Another quick update. All done except for my current project being the trigger setup.

Waiting on the trigger wheel to arrive from the UK.

Going away from the OEM CAS?

Wondering if going with a chopper wheel on the harmonic balancer would offer any advantages.

Give us a bit more info on this one.

[murrayis]

Well I don't have a CAS at the moment so this setup was cheaper than a new CAS.

Many systems use the trigger wheel on the Balancer so it must be a sound theory... I would hope

[Ben C34]

What ecu are you using? Must have missed it.

Running a crank trigger would mean you have to run batch fire as the engine wouldn't know what cylinder (out of 1 or 6 etc) is on it's firing stroke?

[murrayis]

Haltech.

36-1 on the crank and a trigger on the cam so it should know where everything is

[Ben C34]

Sounds like a plan!

[Ben C34]

I really should have looked at you pics with my eyes open!

Looks very nice,can't wait to see it go!

Not sure why I can't paste and quote on my laptop.

Below are some logs off my own car from before a crank trigger and after.

Nissan CAS.

Ross crank trigger.

Thank god there is a cover over the timing belt. It flops around like a pogo stick. Out of sight out of mind .
