M30 Turbo engine build

[danielse38sled]

When i went to ireland to visit andrew when he used to work there. I seem to remember he told me they have a supplier in Europe that gets them their piston slugs, cam blanks and rockers. I have their HD rockers and 284 cam in my current m30 its a beast.

Got to see a video of that running!

They were inferior due to possible casting differences. The porosity of the alloy was such that they actually collapsed in an extreme testing environment.

I wonder who cast them for Ireland. I highly doubt they have a foundry in house.

I have had the reinforced IE rockers in my higher horsepower M30 turbo car for a while now. I haven't had a single issue with them.

Ok, so don't think I'm being critical here please. But I suppose I am......
I brought a set of those for my build and had another shop who built my head do some testing on them to compare to factory originals.
They were inferior due to possible casting differences. The porosity of the alloy was such that they actually collapsed in an extreme testing environment. (I believe they induced engine breaking at a high speed from low revs.)
So I sent them back and had factory rockers installed.
I am building a 600hp engine so, don't want to risk anything.
Love your build.

This is so badass. You are a great person to have in our community Otis :up:

This is so awesome. Can't wait to see what it makes. You're giving me some good ideas for when I build my b35 soon. Might even switch to a b34 block. Keep up the good work sir.

M30 motivation, the head work looks brilliant. I'm itching to drop my head off to my machinist & get it looking the goods.

This is just giving me dirty ideas for the spare m30b35 coming out of my car, turbo m30 into the GF car hmmmmm

Haven't had any problems with the current set up at 7200rpm. Installed new springs, lets see what happens.

I cant wait to see this thing in your car. It will be bad ass for sure.

Yes! Yes! Yes!

Question. Why no rocker locks? Makes head assembly so much easier and looks better too. Plus I've heard at high rpm the rockers can shift with the springs.
