I am redoing my 2.0l bottom end and would like to build a 2.2l stroker bottom. I have been talking with an engine builder, and he is leaning toward the Eagle kit, aiming at 10.9:1 compression. I was looking for more like 11.5:1. I want to run pump 93 octane without worrying about the motor detonating. Am I safe making 11.5:1 compression using that gas? Which bottom end is more reliable? Car will be a daily for a few months. Any help is greatly appreciated.

ALSO: top end is a b16 head with a port matched edlebrock victor x, port matched hy tech replica header, skunk2 cams ( i believe pro2's, but am not totally sure, bought this car built like this) original bottom end was tuned by jeff evans and made 12.5:1 comp and 241 whp. I'm trying to build a bullet proof bottom end and have it perform as it once did if not better.

 

11.5:1cr should be no problem on 93oct fuel.

as for the stroker kits you mention. the crower would have better overall qualitly/machining/fitment but will probably cost you more than the eagle. both will do the job well.

 

11.5:1 wont knock or throw a rod on 93 octane? Also, what makes you feel that the crower parts will have better quality and fitment? It is a more expensive kit, but thats not the issue with this build. I want this motor to be bullet proof. I just want to do this build once, and do it right, so thats why I ask so many questions.

 

(Speaking personally here, not as a Skunk2 rep)

I put an Eagle stroke kit in my turbo GSR and was very happy with it. I got the super lightened crank version. I was surprised when I went to balance the rotating assembly to find that it was only 4 grams off on one rod. It was very nearly perfectly balanced right out the box.

No first hand experience with Brian Crowers kit so I can't speak to that. Just thought I would share my Eagle experience.

 

92mm Crower stroker kit here, and couldn't be any happier. The fitment was perfect and the quality is far superior than the Eagle unit my friend used.

 

Oh...that is Crower NOT Brian Crower.

 

specs? dyno?

 

i would imagine they are both the same or at least use the same materials/machining....someone correct me if im wrong...

 

You are wrong my friend. My friend who is a reputable engine builder has found the Brian Crower cranks to sometimes be slightly off on the mains.

 

ok, it seems that the eagle would be the best. i just became aware that brian crower is seperate from crower. so the eagle kit in a b20z bottom end with a b16 head is supposed to make about 10.9:1 compression. Will this motor make good power and be safe/reliable on 93 octane pump gas?

 

oh yea. since a b16 comes with 10.4 compression from the factory.

i know thats not where you wanna end but it'll run fine with 10.9

 

it'll be fine...to run effectively nothing bigger than TypeR cams lol.

 

Just curious why not swich to H series instead of spending ton's on a stroker kit?

 

I have a eagle 95mm stroker kit on my car and i have no problems with it. I havent got it tuned yet so cant say much bout the performance just yet. But when it come to fitting i had no problems balance was right on... its a good kit

 

bought the car with a built b, rather than do a whole new swap i would like to build this bottom end.

 

H2B!! you already have half of the stuff you need to go H2b..

Just a suggestion. stock motor we put out 201 whp with a Ebay header and Crome tuned (stock longblock) and car ran 12.1 in the 1/4 Full interior Crx daily driven. H2b with Cable B16 trans.

 

In my personal opinion the Eagle cranks just look cheap to me. I havent held a lightweight version in my hands, but the normal stroker cranks just look like you are cutting corners to put a motor together.

 

How do they 'look cheap'?

Are there distinct metallurgic differences that you can see from simply a visual inspection? The counterweights aren't polished, but neither are Hondas. Both are forged units...

 

Like I stated in my previous post, its my personal opinion and thats all. I've seen an Eagle and the Probe/Scat crankshafts in person at the shop. Between the two cranks you could tell a difference in the craftsmanship. The casing of the Eagle just seemed a little less "thought out". I'm not saying the eagle unit isnt a good product, Im simply saying I would go with the Scat crank between the two options that were in front of me.

 

how long are the rods you 95mm guys are useing? has anyone used a scat crank? or one of the ericks racing cranks?
