Default EZ30R-T Buildup..

Since I am rebuilding my H6, I thought I would post up some pictures of the build as it is progressing.

For the curious, here is the parts list:

New EZ30R case and crank.
Custom Pauter Rods (5.180 long, with smaller H6 small end)
Supertec Forged 8:1 CR H6 Pistons
Supertec High Rate Valve Springs and Retainers
Supertec Exhaust Valves
Stock EZ30R Heads with variable valve timing and lift


Case halves and crank and rods all together.


I actually got permission to do this in the dining room.


The crank (stock), with the Pauter rods attached.


I torqued them to 50 lb-ft to start with… then measured the stretch.


Case half ready to drop the crank in.


Drop the crank in.


Put the top half on and seal it up.


Cut the rings.


The pistons with rings, ready to install.

Is there any reason why you're not using Total Seal gapless rings?

Any pics of how to get wrist pins 3&4 into the block? I never realized they'd used the same method to put them in as the H4's...

Good question. If you do the center pistons first, you can just reach down from one of the side pistons to slide the wrist pin in. Since the block case itself is pretty short, it is easy to manipulate the rod to get it in the right place.

Getting the wrist pin clip on is another story. A very long thin pair of plyers is needed, and patiences and steady hands.

All in all not that much harder if you have a few critical tools, but a bit more time consuming.

I used the Royal Purple Assembly Lube... That oil was just sitting there for some of the bolts. The assembly lube is nice and thick, and I used a lot of it. The motor had a nice smooth feel turning over once assembled.

Hydra EMS, same as I has before. (Remember this is the same setup as before, just a new motor with forged rods and new valvespring componets).

That is just the normal 'wrinkle' VHT paint, which works well on surfaces that are not perfectly smooth.

These are the stock rings, which so far have worked very very well. Jeff Perrin's H6 is running strong at 600whp on pump fuel with the same pistons and rings.

I am running a GT30R .82 for the break in, then a GT35R for the Subiefest 2 Time attack, then I will fab up the GT4094 twin scroll.

Thanks!

I fired it up today for the first time. I'll post a link to a vid in a bit. What a sweet sound it makes! It is always nice to have it fire right up after all the work getting it together. Now I just need to get some miles on it and get it on the dyno before the Subiefest 2.

Cheers!

Did supertech change their piston pin clips? Those look like stock ones. I compared, and found the stock around 5 thou smaller diameter wire than supertech. They could jump out, and cause a LOT of damage if not correct.

Those are stock ones. I worked them just a bit to make them push a bit harder. They were very close to the supertec ones, and my first failure was related to the wrist pin coming loose.

Awesome Jeff! Glad to see someone is making progress with the H6.

Better get that Snap-On wrench back otherwise Dustin will be pissed.

Now I can watch this and possibly get some excitement back for my own project....

Ahhh, makes complete sense. I guess if you had a pair of right angle pliers, it'd make life a little easier with getting that clip in too, eh? I can't imagine trying to clip it from another cylinder width away.

That's what I thought. The supertech clips are a lot harder to r&r as they have no tang at all. The wire size is slightly larger than the stock ones, and would be less likely to pop out on their own. I had to make a tool to install the center ones. BTW, outback motorsports in southern ca. is closing the deck on this motor.
