¯\_(ツ)_/¯

If you have read my build thread, I have two turbos to make the big power. That said the Gt3076 I run could for sure make 400whp. I ran it to 30 PSI before with just that turbo, and it would spin street tires on dry concrete to 90mph. But I didn't make 500whp with just that turbo.

Got my pistons :)

The engine will be ready soon, time to order more parts...

83.5mm
8.5:1

Head got surfaced and a rebuild, block machined to 83.5mm and surfaced, all engine parts got acid cleaned.
The crank is one mil smaller then spec - a decision will be made on sunday and the assembly.

Got the oil cooler adapter, oil pressure sensor and all the rest.

What ring gap should I go for ? it is a street car.
The rings manual says 0.050" I saw people go 0.043"... - aiming at 20-25psi of boost.
At what gap do they come from the manufacture ?

Weisco XX rings? Follow the instructions. I know 100% that .0050 is wrong. It's a multiplication factor of the bore size.
I highly recommend having te machine shop gap the rings.

I was wrong with the numbers, the factor is 0.0050" the bore is 83.5mm=3.287" so my ring gap should be 0.0050"*3.287"=0.0164" right ?

Thanks

Getting somewhere

Im surprised you bought your pistons after having the block bored. What is your piston to wall gap?

your pistons are in backwards.

Nope.

No they arent lol

The picture is from the back

It was an engine builder joke. first thing I tell everyone who just finished a build.

I actually did install 2 pistons backwards....:facepalm:

No they aren't.

Yes they are.

I like turtles

Dropped my heart there with the backward joke...

I'll clean the head as much as I can and I'll shorten the oil filer threads there.

Next thing is getting the ARP2000 replacement for the con rod bolt that I broke with a bad torque wrench.

A double torque routine for head studs is a must ?

Thanks

Nice progress.

I use triple routine: 20, 40, 55-60 (depending on whether you're using lube or not)

I mean do the 25-45-65 twice... tight loose and tight again...
