Is it possible to fit a v9 nitrided crank into a phase 1.5 block? And is there any benefit in using this crank compared to the original v3 crank, if used in conjunction with wiseco pistons and eagle rods?

Yes it is possible, but the block would need machining to take the repositioned centre thrust bearing. The V9 on Sti crank has additional oilways for the main bearings which help if you plan to run at high load and high revs (ie on an engine running with 2bar boost say at 8000rpm)
I'm considering the same thing for a high reving engine...but there is no way I'd be using eagle rods...I'd prefer a set of standard ones over them personally
If you want the work doing speak to Lateral or Zen, both can arrange it for you

I don't personally think that Eagle rods are any better than the current stock Subaru rod. By that I mean in terms of material and design. There are better made rods out there, I have been deeply unimpressed by the Eagle rods that I have seen for various engines of Japanese origin.

So you just don't like the look of them then? It's not based on any technical evidence or known failures?
Not being funny mate its just that I have a set of these. They have done circa 30,000 miles at approx 360bhp and they have been fine. Just built a short motor for what's going to be a 450bhp+ car using these rods and I need to know that they are upto the job. If your statment is just by looks then I can live with that. Would be glad to hear any more technical stuff to support your theory.

Some phase 1.5 blocks are end thrust, so you may find it drops right in. I personally don't have a problem with eagle rods, I think the main problem with them is they are "too cheap" and perceived as low quality.

Here's a pic of one of my eagle rods that I am currently using in my rebuild (see my thread in projects section) . They, for want of a better word, **** all over OE rods. Draw you own conclusions. They also come with ARP rod bolts they may be cheap but you can tell by looking at them that they are a far, far better rod than the OE ones.

The last set of Eagles' I looked at were going into a Honda 2.2 Vtec, the little end bearings were all a different size, and the finish on them was shocking. Then I read an intersting article from an Australian magazine compairing the various yield strengths of stock and aftermarket rods...the Eagles failed before the stock rod! Unfortunately I've been unable to find this article again

Is it still snapping drive shafts at about 4000rpm ?

I've also just rebuild a engine using eagle rods and i cant see what your on about when it comes to the finishing as mine looks floorless all my gugin pins fitted perfectly and as for the strength i think thier not as strong but lighter it depend on how far they took them in the test i would of thought.
