    blown wrx motor help

    I have a 2004 wrx that just took a dump on me. Going to take out the motor here real soon as soon as the snow melts. Looking around and seeing what years engine (2004-2006?) can just drop right in. Not looking for STI swap or anything fancy like that but just straight direct drop in. Found a 2006 wrx with low miles and was wondering if that would be fine? thanks for the help!

    If you want direct drop in you're gonna need an '02-'05 motor.

    thinking of doing a hybrid build. Going to use the stock heads, but heard of a lot of problems. first i need to find an STI block, but not sure what i need to complete this:

    -Sti head gaskets bcs compresion ratio will change
    -tunning? (what type should i get) if needed
    -looking for a stock sti block, nothing fancy, no forged internals


    any suggestions from others who have done this before, thanks!

    ARP Headstuds, larger injectors (if you're still using stock), various gaskets, and tuning. You will likely want an oil pump too due to debris in the oil. And based on mileage a new timing belt and water pump.

    i just did a rebuild on my 05- 99K miles.

    Before you make a decision be sure to pull the heads and confirm they are not cracked. Mine had cracks radiating from the spark plug tips to the valves.

    Mine was already built when we found this out and I had to get new heads too..

    I ended up using the same block and replacing everything else and did a 2.2 stroker, ARP Head studs, new oil pump, gaskets ... All that good stuff.

    The one thing we didn't do was change the injectors (oversight) and with the initial tune the results we not favorable. We are tuning tomorrow with Pinks and we will see.


    Good Luck
