After all this we threw on the heads and started building up the motor.

Sadly we got stopped right here as the timing belt gear that goes on the crank was stuck on there and did not one to come off so working to get it off one of the teeth broke off. SO got to wait till tuesday till that comes in.

Not gonna take the chance with the oil pump with it possibly being a spun bearing in the old motor so got a new one of them. The water pump was fine so I am reusing it and only getting the one new timing guide thats the one that broke on the removal of it, as for every thing else it all spins free and good and the tensioner is nice and tight and strong.

i hate to be the barrer of bad news, but that is not an STi Block.... it is open deck and only has one PCV vent on the back of the bolck...

if this is a NA 2.5l Block you will have way high compression...

Oh I do know this is a open deck block but it as been fitted with the correct pistons for the job sitting at 8.5 compression. I was curious on when some one was going to notice that. So good eye on you. As for it being strong enough yes it is plenty strong and will be able to handle 400 no problem. As for the head work sorry did not think to take those pics and as you can see the heads got thrown on in no time.

Nope no lie all the internals are sti. which pretty much makes it a sti motor. Yes it is a open deck block instead of semi closed. From looking into it and talking to the guys that supplied the motor this motor will be able to with stand over 400hp. There is one small brace that seperates the semi closed from the open. The parts list above are the parts that are going to be the power plant. I will change the short block description now.

they bored it the 8 or so mm to accept oem 257 parts? something seems strange here. or they're saying its just as strong as sti oem shortblock by using aftermarket rods and pistons?

just trying to understand what was done.

I do not think you'd have a problem with 400bhp with either open/semi-closed/completely closed. I would just question the cost of disassemble, reassemble, machine work vs. buying a new factory oem sti s/b

Well this motor comes from Outfront Motorsports they are known on here by a few people for there closed deck block. LOL not my shoes. The block has sti pistons, sti rods and crank, then is all set in there with ACL bearings. The cost was well worth it being pretty much 100-200 to upgrade from my little dinky 2.0

just curious as to why you arent going to run forged pistons? the only thing more expensive than building an engine is building it twice...

seen them blow on stock tune & also stage 2 tunes
aggressive and conservative, and i won't name the tuners neither, but they're well known

best to just replace them and should not have to ever worry about it.

either hit or miss
there are some that are going for a while on the stockers while some have RIP, so you can go with them and maybe they'll be fine. Who knows
