you hope its done properlyall why I suggested just buying an IAG short block - this is all done properly . . . but i'll be the first person to admit that buying isn't the same as the building experience . . . but perhaps building doesn't count unless you do the machining yourself . . . the point of that comment is to say evaluate and and understand what your limitations are and make a wise choice for yourself.
So, the OEM Subaru short block from IAG is approx. $400 more than directly from subaru. With the cost of machining would it be more worth while to purchase the IAG OEM Block?
Does IAG do any machining to these OEM blocks? I don't see anything eludes to that on their website.
It refers to the cylinder size so you can correctly clearance the PTW.I pulled the trigger yesterday a bough a used short block with one head still attached. The seller said that the engine was from a WRX but the case halves are labeled AA and AB. So, does that mean that is was from an STI and not a WRX? The seller only bought it for the RH head.
Check to make sure the spring clip is out, or make sure you're tapping on the correct part. If both of those check out, maybe tap a little harder, but they should just start sliding out without having to get creative.If it won't come out, do I get a bigger hammer?
Correct. I was aware of the what the letters meant. For some reason I was under the impression that the WRX case halves used different lettering. It is a single AVCS engine. Could that be what makes it a WRX engine and not a STI engine?It refers to the cylinder size so you can correctly clearance the PTW.
