Manley "Graded" Pistons now available at EQ Tuning!
As some of you may know, Subaru blocks come from SOA with A and B grade cylinder bores which can be miss-matched in a single block. A and B refers to slight variations in cylinder bore size and Subaru uses A and B pistons accordingly. This variance in bore size posed a problem when installing new forged pistons without boring/honing the cylinders because most forged piston manufacturers only offer one 99.5mm size. For this reason, we have never offered a "drop-in" piston engine in the past.
Recently Manley came to the rescue by creating A and B graded pistons to match the two sizes that come from the factory. We have measured and clearanced out a few sets of these now and have found them to provide nice consistent piston-wall clearances. So with this new option, we will now be offering brand new built engines without boring/honing the cylinders.
This has two main benefits. First, since the cylinders do not need to be bored for an oversized piston, we will retain the full thickness of the factory cylinder liner. This means a stronger overall cylinder wall that is less likely to warp and go out of round when running high boost and power. Second, our prices for brand new built engines will drop significantly because we will be saving on the machine work. I will be putting together the final pricing for this new offering over the next couple days and will release it next week.
Finally I'd like to say that the quality of Manley pistons is really nice all around. They come with offset wrist pins to decrease piston slap, and all pistons come with coated side skirts. I'm very happy to have this option as I believe it will be really beneficial for a lot of folks.
Thanks

Glad you are supporting these pistons. I myself got bashed on for going with the drop in Route
New block with this setup is probably the most reliable route for a power platform setup
Good write up Ed

The point is that these pistons come in two variants (A and B) of the stock 99.5mm size to match the slight variance in the factory bores. So the block would not be running 100mm pistons but rather stock size pistons matched to the specific factory cylinder bore.
We will still be offering our standard rebuild services using 100mm pistons with boring/honing when starting with a used block.

I agree that starting with a new core and using these pistons is the most reliable route since you retain the full thickness of the cylinder liners. That being said, we don't just buy assembled stock shortblocks and pull out the pistons to replace with these. All of our brand new blocks start with new OEM case halves, new OEM crank, new rods (OEM or Manley), King bearings, and Manley or CP pistons. So all of our blocks are still fully bluprinted and stage 1+ blocks are still balanced as well.
Thanks

Here is all the updated pricing for our new built engines using the new Manley Graded Pistons!
Shortblock Builds:
EQ Stage 0 Built Shortblock :
This is our basic built shortblock all the same quality components as our stage 1 block. The only major difference here is that we don't do any balancing of the crank, rods, and pistons. This is a great engine for anything up to about 400whp and 7000RPM.
- Brand New OEM Case, Crank, Rods
- Manley Platinum Series Pistons, pins, and rings
- King XPG Series Bearings
- Complete Inspection and Cleaning of block, crank, and rods
- In-House Clearance, Blueprint, and Assemble to our strict specs and tolerances
Price: $3200 w/o core (All Brand New Components)
EQ Stage 1 Shortblock Build:
This is the same as our Stage 0 block with the addition of balancing the crank and rods. When a core is provided, we also resurface the block and line hone the main bearing housings to get bearing oil clearances back in spec.
- Brand New OEM Case, Crank, Rods (if no core is provided)
- Manley Platinum Series Pistons, pins, and rings
- King XPG Series Bearings
- Complete Inspection and Cleaning of block, crank, and rods
- Magnaflux Crank
- Balance and Polish crank, rods, and pistons
- CNC Bore and Hone (only with used core)
- Line Hone main bearing housings (only with used core)
- Resurface block surfaces (only with used core)
- In-House Clearance, Blueprint, and Assemble to our strict specs and tolerances
Price: $2900 with usable core (case, crank, and rods); $3400 w/o core (All Brand New Components)
EQ Stage 2 Shortblock Build:
This is our Stage 2 Block with upgraded Manley I-Beam "Turbo Tuff" Rods. We perform all the same balancing and blueprinting as on our Stage 1 block but with the addition of stronger Manley rods. This engine is good up to 500-600whp.
- Brand New OEM Case and Crank (if no core is provided)
- Manley I-Beam "Turbo Tuff" EJ257 Rods
- Manley Platinum Series Pistons, pins, and rings

- In-House Clearance, Blueprint, and Assemble to our strict specs and tolerances
Price: $3800 w/ core (good case and crank); $4000 w/o core (All brand new components)
** Sleeving and O-Ringing also available. Please call for pricing and options. **
