This is what I did..

I did this other day,

I was doing some high RPM pulls (7K running 15PSI) tuning my Megasquirt II and pop,

I though it was a manifold gasket, till I pulled it apart, and saw the head gasket hanging out the side of the block..

I bet you said "DAMN!" or "BLAST!" when you discovered that little gem Nige!

I think the words were a little stronger than that :-)

I think I may have caused the issue,

I had also changed the spool time on my turbo (on this run) so it came on stronger at lower rpm ( the turbo has a 15psi actuator that I fitted a external spring, so it would open at lower psi, 7ish, but still hit 15psi at 5.5K and up, but this run, I released the spring tension so it hit 15psi at about 3.5k), any way it came on strong, second to third and pop..

live and learn, my first head gasket ever..

anyway when the weather clears up (I live in Tassie, and got no garage) I'll replace the head gasket. I need to find some more engines and build something up that will last a bit longer ( head work, arp bolts, etc, )

Hi,

Sunday was a semi nice day ( 8:00am to about 1:00pm), so I pulled the head off to have a look,

also this gave me the option to fit my EGT probe

Hi,

Got it all back together and it's running very nicely,

I'm still tunning, fuel and spark, had a little 'pinging' at high RPMs so I wound the spark back to about 18 degrees at 7K, 200kpa (15ish PSI).

the EGT is very nice, and super fast (expose tip),

what size intercooler piping did you use? very nice fit up behind the headlights!

It's 2 & 1/2 inch

I bought a Hilux on the weekend!

I only have this picture of it at the moment, it's my first 4x4 and I'm in love

It's an 08 turbo diesel with 24k on the clock, Moreton Island awaits...

The GF has been informed that she's now number three on my list of most loved,

1-Datsun

2-Hilux

3-GF

is that your gts-t too?

I drove the Ohio Tail of the Dragon tour with my club. 450 miles of tight, twisty roads, :laugh:

I cut the 5 floor replacement 18 GA steel pieces I need to fix the five rust holes in my floorboard. I may need one on the bottom back part of the driver's side frame rail though. Not sure how to weld something on the bottom with a MIG without getting burned. Might try fiberglassing that small 2X2 inch area to avoid that.

I finally tore the motor out of the 260Z so I could start tearing into it and get the engine bay cleaned up. Got a lot done and feeling better about the whole thing, thus far.

What specs are you building the motor to?

Yep, i'm about to put it on ebay for $6000 starting bid, I'm not allowed it as a company car so it has to go. I'll miss it when it's gone.

I've only ever properly gotten into it twice and both times ended up in a lot of smoke and drift through 2nd gear. They're very fun to drive but s#!t on petrol.
