I need to decide on which one i want to go with for my 02 wagon. I just found out that i'm getting ready to throw a rod in my motor and i'm having a tough time figuring out what i want to do. SUGGESTIONS PLEASE!:D

go with the 2.5, theres a long list of benefits and if your pulling the motor to fix something might as well, and for the difference in price for the blocks its really a no brainer. PM me if you need a price on a block.

Easy
2.5 no brainer

2.5L you will love the extra TQ low down..... but if not, buy my ready built up 2L and set yourself apart from the crowd.

catch it before it blows and buy a 2.5L STI new shortblock..... best $1800 you can spend at this point....

I just picked up this short block for $600 shipped, it has 1200 miles on it. I personally am going to go with SOHC rs heads so it made more sense to me to buy a block, rebuild it my self, and use the money saved towards a set of tech works forged pistons made specifically for the SOHC application.

I had the same question about two months ago. My motor was fine.. I was sitting at 300awhp and wanted A LOT more... so... either have to build the 205 or swap up. I choose to build the 205. Mainly because there aren't too many truely badarse 2.0 in Subbies. 2.5 hybrid swaps have been done to DEATH and it gets old (personally) seeing the same thing over and over again. On top of that... a strong 205 can still make some serious power.

Can hate too much on the 2.5 tho... it is done a lot because it works well.

get the 3 liter ;)

thanks a bunch guys. i really had no idea what to do on that decision. besides the extra torque down low, what else can i benifit from?

I've seen some graphs of built EJ20's and EJ25's running GT30R's. I was surprised how they differed. At least visually. Before like 3500 - 4k there is definitely some differences. Big ones in some cases. But after 4k they were both well on their way to 350-400+awhp. People are doing 11's on the EJ25 and on the EJ20. A useable 8k rev limit in some cases with the EJ20. The EJ25 has more go pre 4k thats for sure. But I don't drive there unless I'm going to the store. I dunno. I'm sure there tons of evidence contrary to my opinion, but if you're looking at 350-400awhp, hmmm, I think a built EJ20 can serve you quite well. YMMV.

cheers
