Default buying a new short block(what to get?)

im going to buy a new short block from the dealer. I have a 98rs that went kaboom. I have 98 heads. now what shortie to get. The goal is long term reliability. being able to use my 98 dohc heads, and being able to use the computer/harness in my 98 impreza. any thoughts
thanks,
Jason
BTW anyone work at a dealer that knows the going rates for new short blocks?
How about these new 2.5 sti blocks, is that much better than getting just any old phase 1 or 2 block? Also has anyone done an ej22t or g with 2.5dohc heads on the 98 ecu? with and without a turbo?
thanks again.

I totally agree. If you were already turbo'd in the first place it's a different story. Go with a swap, it's cheaper in the longrun. TRUST ME!

Running any turbo block without a turbo is going to be less powerfull than the stock block.

I just picked my car up today! 2000 RS, w/ sti short block. I had a bad rod bearing, just out of warranty. I paid $1750 for the block (kinda high, but I hear demand is driving them up). I was quoted $1,760 for the stock block, so I figured what the hey. I couldn't afford the wrx swap, so I'll be taking the round about way. From my understanding, my SOHC should work just fine for now, you may not be as lucky with your 98 heads. I'm in Cali, and my Sube's my only car/daily driver, so I didn't want to mess with jdm, but that's an option too. Good luck!

Get a phase II EJ251 (NA) shortblock. Unless you are going to boost your car pretty quickly, you won't really enjoy driving it with the low CR the EJ257 STi block will provide. With your DOHC heads and a phase II block, you CR will be 11.4:1 with stock head gaskets. It will be a free power bump, but will also require premium gas to not detonate...

Can anyone else verify that? Using the pistons in the phase 2 is ok with dohc heads? Has anyone done it? And if so with what results?
