I haven't tried extending the 622 yet, but luckily my intakes are very good so I will only lap them :)
I had no idea this engine would take this many hours to complete... I'm used to working on 4-5cyl vw/audi engines, so when I started this I was planning to have the engine back in the car in a couple of weeks, yeah right :p

While I'm waiting for my new valve guides I drew a cylinder holder tool you can make if you have a 3D printer :)

Awesome project, any updates?

I'm looking into doing a similar ITB setup.

just a quick update, cylinders have been nikasil plated and bored/honed to my dimmensions by US chrome, cost $189 per cyl, and are on their way back to me :)
I will post pictures and do a dimmension check and RA measurement when I get them :)

Wow thats cheap what were they bored to we pay over 400 bucks here per cylinder there is only one place in the country that nikasils so we are stuffed.

Got my cylinders today :)
I was suprised that there where no documention that verify they are made to my spec.
Anyway i will measure them tomorrow including the surface roughness RA.
DC-30 camshafts are in the mail as well :)

I also got 1,5 spare 2.7 engine today, not sure what I'm gonna do with it, maybe i'll make a coffe table out of it...

Flat 6's make great tables. Keep up the good work.

Can I stack the cylinder to case gaskets?
My stock was 0.25mm, I see from my notes I had to remove 0.4mm from the heads, so I should have a 0.65mm gasket. Or can I use the 0.5mm gasket?

cams arrived today :

4 bearing cams in a 2.7?

So finally I got 5 of 6 cylinder base gaskets....
Installed on p/c to find out that stock rod pins are to long for JE pistons, argh

Cam timing, took some time and some tries ended up with
cyl1-2-3 3.89mm
cyl4-5-6 3.81mm that was as close to 3.8mm I could get on the DC-30 camshafts

The dial goes backwards from 0, so this is at 3.89mm

Made myself a camshaft tool
http://i380.photobucket.com/albums/o...ps08ec9fa3.jpg

So I bought the camshaft oil restrictors, and after reading much for/against I decided to drill it somewhere inbetween.
From left stock - drilled - restrictor

Then I looked into the camshaft housing, and dooh there is a much smaller hole than the stock 6mm, I'll measure it tomorrow, but anything bigger than that up to stock hole is meaningless then...

I drilled mine 3.5mm, but if that is bigger than what's in the camshaft housing than it's the same if it's 3.5 or 6mm...

u r correct on all that u say here...but... keep in mind the entire oil circuit when using the later "restricted/smaller hole" fitting has increased overall system oil pressure which is another gain from using the smaller hole fitting...the other gain - debated by many - when using the restricted/smaller hole fitting, less oil is on top of the motor = better oil scavenging by the oil pump as there is more oil down in the sump that can be scavenged & a bit less fluctuation in the qty of oil in the oil tank...
