Question 2004 engine questions

Ok, I have a 2004 WRX with the 6 in the 6 spot of the VIN.

it is completely stock.

I am looking to replace the engine as it may cost just as much to replace it as to fix the head gaskets (does that sound right?) the mechanic said about 2K for a head gasket job, but that was off the top of his head and not an actual estimate.

I looked on Google for the compatibility of engines and such but no luck.

Can any of you tell me what will work in my car. I am not a speed freak but if an STI will work please list those as well.

thanks

Any WRX or STi shortblock will work, however you need 02-05 wrx heads.

I don't know that I would replace a motor rather than do head gaskets though. You never know what you're going to get...

I'm thinking long blocks only. I agree it's a crap shoot on the swap, but what about the cost/benefit versus the head gasket repair. My engine had 95K and I just had the timing belt kit done along with the plugs and fluids (trans too).

First how many miles are on the car? I'm guessing around 120k if you have a bad head gasket with over heating probs. If your going to be pulling the engine and u have no technical ability to do most the work yourself. The cheapest route is going to be for you to get the head gaskets done. The best route is to get the engine re worked if your not looking at big numbers. Hybrids engine are expensive to do. Trust me I'm in the process. And 2500 doesn't go far. Pistons, Rods, decent 2.5 bottom end and some engine work and your still not done. Gotta get head work done valve job. And look at your car being done for 6months plus.

I'm not following you.

My car has 95K on it, I had the timing belt kit done early. The car was driving fine for 16 miles then i slowed to make a turn and I started to accelerate and bunch of white smoke was coming out of the car. It was not getting hotter and it was running smooth (not chugging or hesitating).

I called my mechanic the one who did the timing belt and he said it may be the head gasket but he need to look at it, I had it towed to him.

So my question is which engines can I put in my car, or will it be more cost effective to replace the engine. I will not be doing any of the work myself.

I have found several places online that sell engines for reasonable just not sure how much the swap would cost.

I think you need to thoroughly diagnose the problem before you purchase another engine

If it started acting up 16 miles after you had work done...I'd find a new shop.

But just fix the issues, don't replace the motor. If you're going to do a long block, you need to do 02-05wrx unless you want to do a wiring and ecu swap as well, in which case, just buy an STi.
