I picked up a 2.5 today for a price I could not pass up. My question is do the harmonic balencers interchange from the 2.3 to the 2.5? Other than the obvious pulley/drive.

The 2.3 doesn't have a harmonic balancer. -
Yes, I think the Front PULLEY will work.Comment

Sorry to dredge this up.
Mike, I thought that the late 2.3's in the rangers were the same as the 2.5's, but the 2.5 had more stroke? But compared to the 80's 2.3T, it has smaller mains/seals. Forgive me if I am incorrect.
I ask, as i have a few of the 'newer' 2.3's and i was to understand that their mains were 'thinner' than my 2.3t longblock, and the 2.3t in the svo. This also falls under the fact i was planning a 2.5 build up at one time, so i am a bit interested in the finer details of differences.Comment

Yeah, I have never heard about them being 'weak', and not able to safely go over 6800. Thanks for the info. I was sure the newer 2.3's had the smaller mains(like the ranger block i had mentioned), and just needed the different crank. I have also seen the bearing spacers from racer walsh, and a few other places. I am curious who RE is thou. And just curious but how does that work? You buy a crank from them, then mail in your core for a refund, or is there a two week turn around?Comment

Balance has more to do with the rpm range a engine/crank can endure. At least that has been the law on my old FE's. Couple grams here(pistons) and there(rods) make big weights at 7k RPM.Collecting SVO's is an addiction cured by povertyComment

The 2.5 crank weights about 5 1/2 lbs more than the 2.3. It has some hefty counter weights on it. It is know to flex more also. If you are going to rev it, like Mike, balancing is very important. A popular mod is to remove 5 lbs from the crank. Revs quicker then

Are these Cranks you speak of the "Forged Ones". I had a crank Made to fit the big SVO Journal. Forged and truly knife edged, it was "is" beautiful. A Work of Art.Originally posted by MikeFleming"Specializing in Brut Force and Ignorance."Comment

No Harmonic Balancer?
Maybe dumb question, but in the quest to reduce vibration, is there any harmonic balancer that could be added to the front of the crankshaft (IE fit and be usefull to dampen vibration) for these engines? I realize it would add a little rotating mass, but since the motor dampners are no longer available...Comment

The only "balanced" engines are V8 and V12. Everything else you have to power through the natural frequencies. Even V8s have one just <500rpm. Drive a 500KR you'll know what I mean!
Drop a Wankel in it for no NF!
In my experience bolt that thing down solid and have you passenger pay you for the vibrating experience!Last edited by Henson; 11-10-2009, 10:28 AM."Specializing in Brut Force and Ignorance."Comment

Is anyone out there using a damper on the stock v belt setup? I just built a very expensive 2.3 SVO motor from my 86 SVO and am planning to run 550-600HP out of it. I had it built with an ATI super damper and when I was placing my water pump pulleys on it, they interfere with the superdamper by about 1/8-1/16". The ATI is 7" diameter. I was referred to ROMACUSA.com and sent them a message about the size of their setup. I also considered having an aluminum water pump pulley made 3/4" smallefr in diameter, but it would spin quicker and spin the a/c compressor quicker. Anyone out there using a damper and what brand and how????? Any comments welcome. I hate to use the Esslinger pulley with no torsional vibratin dampening at all with this must HP. Thanks a million for any comments or suggestions. MichaelComment
