Tehnation's Ballin on a budget rebuild!


Recommended Posts

I made a post hopefully someone is making something that big.

 

On another note I contacted JCSpods, and the reason they don't make it anymore is because they use a factory pillar in the process and subaru no longer makes them. So I'm gonna see if they will make one if I send them one.

 

Now I gotta find a used one for if they say yes.

He said 125 shipped, but I gotta send the pillar, they modify it so its permanent.

 

Dirt doesn't matter, they put a mold over it I think so it's mainly just the clips and mounting that's important. My pillar is in bad shape from my dashboard fiasco....

 

Got a $$ on the driver side pillar?

Oh shit, just realized I have a pillar pod sitting in storage from my parts car.

 

R u selling? How many pods?

 

My pillar is dirty as hell, I just took it out.... might be usable, but with the extra weight, might be loose.

hmm.... captain hindsight ... I gotta file my new piston rings, I don't think that should throw off balance much. Either way its too late now.

 

I'm trying to figure out which gap I should use. I'm thinking .006 medium boost.

Anyone know how much boost a billet 20g can put out, I plan to upgrade to a ATP Gen2 GTX3576R after I get the car up and running and dynoed on the 20g to see where I am at and what I need to break 400awp.

Hmm I gotta do this again! Just ordered a 3-4" micrometer to get more accurate readings. And the piston to wall clearance is the total of both sides.

 

 

So I will set my ring gaps according to the chart using the medium boost recommendations, which is bore x .006".

Found the pod, it's a 2-slot, womp womp

 

I ordered the one I found on ebay. Going to send it to that JCSpods custom order.

 

so 50 for the pillar, 125 for the work, and whatever the cost to ship the pillar to them. So roughly 190 bucks. Not bad.

I'm having a hard time getting this stretch gauge on the bolt when the rod is attached to the crank. It would probably be a lot easier if the rod was actually in the block, and it can hang down using gravity. hmmm.....

So got my results with some better tools. 3.914" for my pistons @ .850" from bottom off piston oil ring and 3.917" for my bores, giving a .003" piston to wall clearance.

 

Going to file my ring gaps to .024". 3.917" X .006" = 0.023502".

So I went through 2 rod stretch gauges already, finally decided to spend the extra 100 bucks and get the arp rod bolt stretch gauge, arrives tomorrow.

 

The spring just didn't provide enough tension/force to measure the stretch while the rods were attached to the crank, otherwise they work fine, but with gravity and not being able to position the rod completely vertical while keeping the contact points consistent proved to be impossible.

 

Hopefully the ARP gauge works better with the ARP bolts. Most people I see have the ARP gauge, so lets hope it works the best. Otherwise I will have to actually drop the rods/crank in the block to let them hang then try to measure.

 

What I've tried so far:

3rd times a charm?? What I hope will remedy the situation:

To file piston rings you need a ring filer and something to deburr the edges, I am using a 400/1000 grit whetstone. You file inwards! I matched my new rings by weight compared to the old rings. Old ring gaps were too big, probably due to the new hone or previous builder error.

 

Bought this ring filer and whetstone:

And we have a WINNER!! The arp gauge is just superior, the spring is very hefty and can clamp itself onto any bolt upside down side ways or whatever you need. So for anyone about to do this , don't waste your time with any other gauge other than the ARP!

Always wondered why everyone recommended that one, thanks for sharing. Good info.

 

The difference is night and day. If I hold the tip of the gauge, the part that moves, in my fingers, it will move or compress the spring all the way from the weight of the entire gauge alone. If I hold the ARP tip, it doesn't go anywhere or the spring doesn't compress at all.

So with the new ARP gauge I got everything torqued between 55-60 ftlbs with a stretch of .006 on every bolt.

Started filing my piston rings. I file inwards with top side of ring up, and also make sure to only file one side of the ring, its counterproductive to file both sides, keep one fresh and perfectly finished and only trim from one end.

 

Make sure to do it slowly, you can take off material but you can never add, one extra rotation is all you need to over shoot your goal! Get accustomed to how much you take off with the amount of rotations. Make sure you try to apply consistent pressure to keep your rotations more uniform. File, measure, file, measure, file, measure, file, measure, file, measure, file, measure, file, measure...... its that precise!

After I finish filing the top and 2nd rings to .024" ring gap it will be time to assemble the shortblock!
