Default Forged internals or Crawford S2 block?

Whats up everyone. Just needed some opinions on whether or not to get a crawford S2 block or should i put in forged pistons and rods in my stock STI block. My STI right now makes 400whp with a ultimate racing stage 3 turbo kit, I have all the supporting mods, I run a utec tuned by MSPT. The reason I am asking is because I want to get into the 500 whp range and I know the internals are a must. Thanks everyone for your help. Greg

Thanks guys for your help. Time to get the S2 block I guess I know what my winter project will be. I never pulled a subaru engine before but ive done it on mustangs and my fathers race cars. Is this going to be a nightmare or should I pay somebody to do it. Thanks Greg

Swapping a short block is a little more involved than pulling an engine. Pulling the engine is just step one.

I am just curious as to why you think Internal engine upgrades for 500whp are a must?

If there is a good engine shop around your area I would save your money pull the engine & have them put in forged pistons & rods.

The crank is fine for that sort of power so I was told.

Get pauter rods from Crawford & his CP pistons & rings and have a shop do it that knws what they are doing.

I have a shop around my home that I trust even with Boxer engines and that is my plan down the road. Then send your heads out somewhere & do what needs to be done whether you want stock cams & AVC or after market cams & none.

I mean an S2 is a stock block with CP forged pistons stock STi rods & crank no more no less. Ok except it is a brand new block you have to buy.

I would say it is because the stock pistons are junk & most people can't tune or setup their car up correctly & things happen. Especially when people don't always take car of their cars.

Also when doing a high HP car do it right no shortcuts especially tuning...but I would feel safer either way with at least forged pistons & rings...That is the "achilles heel" of the STi.

No race motor lasts that long.

The reason why i want to put in forged rods and pistons, or crawford block is because its an added precaution. My car is proffesionally tuned and always taken care of

Buy a AAA membership and make your 500hp. When and if anything breaks call the number on the back of the AAA card, get a tow, and proceed with your S2 install.
