We are hoping to get some opinions on our engine build plan. We found out that our 2002 WRX donor with a "built" hybrid motor was really a stock EJ257 block with stock EJ205 heads. So, since we can't leave it with its current compression ratio, we are preparing to build the motor.

We are thinking 300-350hp with a rev limit of 8k.

Current idea:

EJ257 Block modifications:
JE FSR pistons for 2.0 heads
Manley/MPS +2mm H Beam Rods
75mm OEM Subaru Crankshaft (swap to WRX instead of STI)
King Main Bearing Set (#5 Thrust / 52mm Journals)
King Tri-Metal Performance Rod Bearing Set
ARP Subaru EJ Series DOHC Headstuds

EJ205 Head upgrades:
GSC P-D EJ257 Beehive Valve Springs w/ Titanium Retainer Valvetrain Kit (Use factory spring seats)
GSC P-D Subaru EJ Series EJ205/EJ207/EJ257 Chrome Polished Intake Valve - 36mm Head (STD) - SET 8
GSC P-D Subaru EJ series EJ205/EJ207/EJ257 Chrome Polished Exhaust Valve-32mm Head(STD) -SET 8
NOT machine to match combustion chamber diameter - leave as is (Nasioc has mixed opinions on this)

Other upgrades:
Killer B Motorsport Ultimate Oil Pickup
Killer B Motorsport Oil Baffle Windage Tray
STI oil pan
OEM oil pump
Upgrade from current modded light blue injectors to Injector Dynamics Fuel Injectors 1000cc
Partial TGV deletes
Cobb intake
Gates racing timing belt
Stock headers
STI catless up-pipe
Forge full recirc bpv
Grimmspeed ebcs
255lph fuel pump
FrozenBoost AWIC
Group N engine and transmission mounts
Turbo TBD


Outsource:
-Balance Rotating Assembly


What are everyone's thoughts on a build like this? We have been speaking with a couple of tuner shops. They would prefer that we switch to the EJ257 heads, but based on our budget and the cost of EJ257 heads, we are thinking we should stay with the 205 heads. With the parts listed above, we can afford to do this... it'll cost around $3k. We don't really want to spend much more of this.

Opinions-
Too much?
Not enough?
Destroked a good idea?
EJ205 heads okay?
Anything we are missing?
