Darton sleeved EJ257 block

I purchased this block 1/29/2009 from LIC Motorsports in Novato CA. They has it sleeved for their Time Attack car, but ended up with a sponsorship from Crawford, so they sold it.

It was sleeved by Race Engine Development in Oceanside CA. This is the shop that sleeves the engine for the GST L, and I believe it is the shop that Darton sends Subie blocks to in this part of the country.

It was then given to Rob's Auto Machine in Hayward CA. They build engines for GST as well. See a pattern? ;) Anyway, the block was cleaned up and bored to 100.01mm (ready for finish hone depending on pistons). This was the point where LIC changed plans, so no further work was done to the block.

After I brought it home it sat in the box until last spring when I started cleaning it, taking measurements, and chasing every thread on the block.

The marks on the case mating halves marks have been inspected by multiple shops and deemed insignificant. A very light filing was done just to be sure nothing was sticking up.

As mentioned above it needs a line hone. This is standard for a sleeved block. Just know that you CAN NOT just drop bearings in this block and go. One of the mains in particular is smaller than my EJ25 crank journal.
