^^ are you kidding me??

Daily driving is under 6k rpms..

2.3L is the way to go !

Half throttle is more then enough in any situation..
which sounds better for daily driving guys??
instant throttle response or next to none..

 

2.3L is not the way to go with those kind of revs in mind, esp with a 4G64 crank!

I would not even touch a 4G64 crank again.

This bottom end had 30K on it before the crank failed and this was only 350awhp/ 350awtq.

As far as 2.3L go, only buy one if you intend to use a Eagle 100mm crank.

 

those are nice pics... but multiple major companies use the stock cranks with balancing and knife edging as an added plus because they can handle that amount.

I only suggested the 2.1 and 37r because that setup will dominate the 2.3 on the drag strip.

There are pro's and con's to either setup on the street but only one of them will be the victor on the track.

2.1 & 37r FTW.

 

i agree 100% on this one! get a stroker that uses a decent crank. thats what the UK guys are doing and they are reving to 8.5K all day on road courses over here.

i think the 2.3 is the best option. will make the car more driveable and less like a manic reving honda (nothing against them but i dont like "oh 6K now i have power").

2.1's or fully built 2.0s are good for drag racing but you dont want to be reving to 10K all the time in a DD. that kind of abuse will shorten the life of an engine considerably.

just my thoughts.

I'm usiing the AMS 2.3L with a 100mm Eagle crank. BUT is it really the crank that takes the most stress in a stroker motor??? or is it the rods or pistons???

 

i guess i should have read the whole thread.. doh

 

Version,

Are you talking about the 2.0 (63) crank or the 2.4 (64) crank?

Cause the 4g64 crank just can't handle the high revs for the long haul.
AMS doesn't even use the 64 cranks anymore. They use Eagle.

For street driving, I'll take a 2.3 over a 2.1 anyday of the week. There actually is some truth to "there is no replacement for displacement".

 

there is replacement for displacement=> efficiency.
Im all for the 2.1. As a daily? It will definately last longer in the long run. Why?
Rod angularity. You rev that 2.3 to 8500 rpm, at that rpm there is alot of stress on your con rod and crank bearings. Plus you need to run way less aggressive ign timing due to shorter dwell time @ TDC. The 2.3 is a good street motor b/c of the added torque, but come on; these arent hondas we're talking about. If I were building a road race motor, it would be the 2.3.

 

im with you on that. 2.3 or even 2.4 all the way!

i was told recently that a shop over here has been running their own 2.4 (using a custom 102mm crank) to over 9500rpm! infact they reved it to 9700 at one event. and these guys aren't just any old setup that have no idea.

also Moses Evo on here is looking to build a monster 2.4/4 with a 4G64 block that will be reving well past 10K!

updates?

 

for road racing a 2.3 for anything else a 2.1

 

That crank looks like it was a reman and undercut.
A good standard crank should not have had any problems.

Also, From the Pics I have seen, AMS (the real one in chicago) does not use EAGLE. They use K1

 

Aren't Eagle cranks made in China? I never heard of K1 cranks, DTM. Do they make high quality engine bits?

 

You will slowly see that everything people HAVE been buying this whole time have been made over "there".
Doesn't mean all the quality is bad. Just have to know what you are buying and from what foundry.
But yes all Eagle products are made in China.

 

never heard of k1 either.
i'm going for a 4g64/ evo head 2.3.
don't need the high revs, mainly concerned with streetablityand low end torque.
