Subaru Stars ej22t rods cast or forged

alright...here comes a topic that ive heard from aallllll sorts of people. But I never seem to get definite yes or a definite no. Are these forged or cast? I'm considering just going with eagle rods but I was also thinking that if these can hold up to 400 whp i'll keep them. what are eagle rods rated up to?

All the subaru rods are forged, the eagle rods are stronger and would certainly last longer under harsher conditions. According to Eagle's website they claim 900 HP

All subaru EJ crankshafts are forged
All subaru EJ rods are forged
The pistons are either cast or hyperuretic.

I went with the eagle rods. They can be had for 315 shipped at some places.

I think it's funny that for sooooo long on this board even the gurus were saying the EJ rods were cast besides the ej22t's. kinda interesting. oh and i know about our cranks and pistons thanks, I'm not new to these engines lol

If I'm looking to make 350whp with a ej22t stroked to 3.5, is it worth buying pauter rods or are phase 1, 2.5 rods strong enough? This is the first time I've heard that all rods are forged. Is that true even on NA motors?

3.5L?!!!!! You mean 2.35L? You have a massive sleeve setup?! Yes all EJ rods are forged due to the slightly increased stress of horizontal piston design. It really depends on what kind of setup your trying to do to if you need rods. If you intend to push the redline way up then almost certainly you need the rods + balanced crank.

I am personally in the process of a 2.35L EJ22t shortblock build up. I am not intending on using aftermarket rods. Although I don't intend to rev past 6.5-7k, and my CR should be around 8.4:1. I think with this kinda setup I can get to 300 whp (which was my original goal). To go another 50whp. I bet a similar setup could take it so long as the tune + supporting mods are all there.

That is what I was thinking. An extra 780 for pauter rods seems like over kill for my goals but you hate to have to build it twice. If anyone hase some phase 1 2.5 rods they want to part with PM me.

Seems there's a couple of different power levels being considered in this thread. I would say that for the 300-350whp guys the stock Ej22T rods would be fine (assuming a proper tune). For the 400whp guys, you might want to spend the money on aftermarket rods. I imagine that it's been done on stock rods,but it really probably is the outer limit on them. Just because they are forged doesn't make them SUPER strong. There's definitely better and stronger rods out there. If you search around a bit there's a couple of threads with graphic failures on Ej22T bottom ends, and it's generally been the rods that let go.

need2boost,
You are wrong. Even lowly Ej18 rods are forged...

Read my comments above. I will repeat, just because they are forged doesn't make them unbreakable. The design of the rods comes into it as well. The stock rods are a standard duty forged item that holds up well with with doubling of power levels, but not so much with tripling of power levels...

do you happen to know the grade of metal used in each of the rods?

Sorry,
I don't know the answer to that. That would be the kind of question to run by Quirt Crawford, Jeremy@ Cobb, or someone like Sponaugle...

I've run more than all of the above mentioned limits on bone stock ej22t shortblocks. That's stock everything with high mileage, not even rebuilt. With proper tuning I don't see any numbers being thrown out that warrant upgrading the internals. If you're doing a lot of high rpm (over 7500 rpm) or high sustained EGT use (road racing or rally) then I'd consider it.

All Subaru rods are forged not just Ej22t, the major difference between the Turbo block is it's a closed deck and has a stronger piston which is not forged but Hypereutectic cast. What I am getting at is why not look into a good forged piston? Which all to commonly seems to be the real weak link in build-ups.
