don't forget with those new pistons going in, its best to not do drop in pistons...hope that the walls are scarred up too (most likely not).

I would go ahead and do a build on the shortblock while its out and needs to be torn down and checked out. It would be a shame to drop in pistons, install the motor and have a bearing that got scarred under impact of the accident or the valve and then have to do it all over again...I would buy some used sti heads for $600 and build those as well as the block...then slap in a nice complete longblock when everything is "done right" but then again my mentallity is "do it once, do it right".

the block year doesn't matter, it will fit.

a good port job on wrx heads get maxed at about 270-275 intake on my bench...sti heads demolish them once ported and deshrouded

 

I wouldn't buy it for $500 until I saw the piston tops.

You could be looking at:

$500 block
$400 new pistons
$xxx re-hone + piston swap work

In which case you'd be better off buying something else.

 

you forgot about bearings too...but then you look at the cost of having a fresh, stronger block with better bearings for less than the cost of an oem sti shortblock, it isn't a bad investment at all...I would personally save up a bit more and do rods as well...Labor is the expensive part if you decide you want to go back into the block.

 

ya but if there is nothing wrong with the piston tops then i have a sti block for 500 and later on i can put new pistons and junk in it have a brand new one so im gonna go ahead and get it thatns for all the advice ppl

 

I say go for it...if the pistons appear find, the rest of the shortblock should be too.

 

i got the block in great shape a couple of questions were can i get the head gasket and studs for the wrx head im putting on it for a decent price and do i need to get a sti ecu

 

you can get gaskets at jscspeed i believe.... oh and try vividracing....

you do not need a sti ecu! just get a tune from jeff...

 

I've got a set of brand new OEM STi gaskets for cheap that I got with my complete gasket set. I don't need them as I'm on some big bore cometics. For the head studs I would go ahead and pick up ARP studs while you are at it as they are minimally more than OEM cost.

 

do i just buy wrx head gaskets cause vivid has some nice ones and what thickness will be better

 

buy an sti gasket...the wrx gaskets bore is too small

what CR do you want to have in the end? you will be sitting 9.0-9.1:1 with and STi shortblock and wrx head
