Not sure on piston weights actually, didn't compare standard to the 2 MTC ones but there's a good amount of extra material on them.
Head gasket should be here by the end of the month. Ordered from Performance Unlimited, Cometic make them to order and ship them out every fortnight. Could have possibly got it quicker but I've used these before and don't mind waiting.
Once the engine is back together I'll finish the headers off. Looking at getting a Tial Wastegate as well, pricey but I can spec a 12psi spring and not have any worries with boost controllers.

Well Monday was build day but it didn't start until mid afternoon!
Got the head on and then spent forever dialing the cams in. The spacer under the barrels threw things out a bit and it took a bit of working out to get the cam sprockets right so the adjustment range worked ok.
Got the exhaust cam at 110.5 degrees which is spot on but the intake cam keeps falling 1-2 degrees out either way.
Left it for the night to re-check the degree wheel and exhaust cam in the morning then have another go at the intake cam.
Cams dialed in finally, the degree wheel had moved a touch so reset it and double checked it all once I'd finished.
Intake lobe centre is 108.25
Exhaust lobe centre is 110.5
Got a few other bits bolted on but hit a problem with the plenum, the o-ring seals are made of cord and have shrunk slightly so there's now a gap. Measured up and ordered some new ones, hopefully they'll fit.
Can get the headers back on though and finish them off.

Finished welding the v-band clamp, thats the exhaust pretty much done. Need to decide on a wastegate, think I'll go for the v-band Tial as its only a few quid extra than the flanged Tial.
Plenum and turbo are fitted along with most of the wiring. Can't fit the rad yet as the headers will have to come off for welding the wastegate flange on.
Can sort out the breathers and look at making a catch can until the wastegate arrives.

Should be for the price....
Finished welding so its all ready for the final bolt up.
Picked up some mineral oil today but can't find the oil filter I bought, if I actually bought one, so I'll pick one up during the week along with some antifreeze too.
Then its only a bit of spannering away from the go button again.

Thanks, hopefully I've found all the issues but I've still got some ecu settings to double check.
Headers and wastegate are bolted up, had new filter, fresh oil and I've spun it over to get some oil in the galleries and cooler.
Got to go back to work now so rad etc tomorrow

Its alive!!!
Primed the fuel lines and it started 2nd push of the button, idled nicely with a steady .85 lambda, revs cleanly and coolant temps peaked at 70c after ~5mins.
Started straight away from hot too which is nice.
Few bits to tidy up then its dyno day.
