2.2L Stroker Kit
If I were to purchase the eagle 94 mm crank. What else would I need? Would I need a specific length rod, or a certain bore piston? I mean obviously if Im gonna toss in a new crank I will buy rods and pistons. Just want to know if theres anything specific I need to get.
we are shooting for $3,200-$3,500
Here are a few specs
Crank
4340 Chro-Mo
Shot peened and Nitrited
Stress relieved and straightend
Fully Balanced
Knife Edged
30 pounds
Rods
Custom C-of-C Length
Rod ratio of 1.66 vs stock 1.70 vs 2.3L setup 1.50
capable of 1000whp
Shot Peened
Clipped and matched
Pistons
8.5 or 9.5 comp
9310 wrist pins
Custom Rings
85.5mm or 86mm bore
light weight
Special squish area
enlarged oiling
and a few other tricks that the world doesnt need to know about ;-0.
moosa any time ur ready ;-)

So a true 2.2 with a 94mm crank should rev higher right?
No one can truly assign such a figure, simply because no one knows where/when it will break, and no one is going to guarantee that it won't. Likewise, it's pointless to attempt to spin it that hard (9000+ rpm) anyway unless a very large turbo (e.g. 42R) is used and the torque curve warrants it.
The reasons why JUN, AMS, and now GSC have developed such kits is because the slightly shorter stroke and better rod/stroke ratio allow the engine to be a bit more mechanically efficient at high rpm, and relieve some of the mechanical stress associated with the very short (1.5) R/S ratio of the conventional 100mm crank kits.

Cosworth + Eric Hsu = Why buy anything else?
"What a waste of a perfectly good connecting rod. I had to cut it for the sake of quality control and research and development though. I’m sending it out to our lab to do a material compositional analysis, hardness profile, bulk hardness testing, and a microstructural analysis. I bet you don’t see Eagle or those other 15 brands of piece of $hit made in China rod manufacturers doing this. Or even any of the American made rods. This is one of the reasons why Cosworth parts are expensive. You can be damn sure you’ll be getting a good part that will not fail on you though. Don’t forget people - when it comes to cars, you pay for what you get (most of the time…)." - Eric Hsu's blog
He may talk alot of **** and big-game, but he can cause he backs it up. Look at his XS Skyline.

Quality is one of the most subjective terms in the industry...What is quality, truly?...To me, I consider a brand quality when I have consistent, track-proven results...My definition is also cumbersome...Some consider track results to be drag strips, I am not one of them...If you want to see some of the highest quality parts in the industry, look no further than the road course...The only way to test products built for limits are to take them there...Nothing will take a motor to its limits sooner than the road course...AMS, Buschur, SBR, and others have a good deal of knowledge in the industry, but are mix-matching parts that they have tried over the years (usually, a 2.3L 4g64 crank and rod/piston combo)...Cosworth, in this scenario, has been racing for much longer than any of these companies have existed and have much more testing equipment, employees, and general research and development to make a superior product...Those who consider Buschur and AMS to the same caliber haven't tested the extreme conditions that fine tuners like Cosworth, JUN, and Garage G-Force have...
Also, to explain what I am trying to say better try this scenario...I have witnessed statements on this board saying that JAM, a well-respected 4g63 player, makes a head that will outflow the Cosworth product...While this may be true, the heads designed for the JAM application may only be beneficial on a motor with a much larger turbo...Cosworth components are able to be used to see performance benefits for even the guy who wants to stick with a less-powerful setup (or even stock turbo)...While flow may be better with the head on a 37r setup, for example, the Cosworth will still see gains but with what they consider a fair safety margin...To some, rebuilding motors and replacing failed components isn't the issue (some would rather *****-out for power, to make posts to prove what these components are capable of doing)...That's cool, but what about the few of us who buy quality because we know we are getting better than OEM reliability...That is why there is a price difference, and it is well justified for the level of safety and state-of-mind that is included with expensive components.

thanks Greg...best guy i have ever dealt with...stands up to his word and serves like there is no tommorow...
The Jun kit is definitely not upto the job, the crank is good and the pistons are made by Cosworth, but the rods will break if run for extended periods in motors making above 600lbs/ft. Norris in the UK has broken a couple on the engine dyno.
He now uses Crower rods and JE pistons running at 740lbs/ft.
