EPnick22 Posted December 2, 2013 Share Posted December 2, 2013 As above, is it worth having the crank, pistons, rods, flywheel and clutch balanced? my mate reckons its worth being done but I dont know what to do, anyone? Quote Link to post Share on other sites
DevonGT Posted December 2, 2013 Share Posted December 2, 2013 On a forged engine definately. Quote Link to post Share on other sites
TurboTobz Posted December 2, 2013 Share Posted December 2, 2013 I'd say so! Quote Link to post Share on other sites
EPnick22 Posted December 3, 2013 Author Share Posted December 3, 2013 (edited) how much does it all cost? and what does it actually prevent ? say i didnt have it done? Edited December 3, 2013 by EPnick22 Quote Link to post Share on other sites
AdamB Posted December 3, 2013 Share Posted December 3, 2013 Depends where you take it to be done and how accurate you want it done/ their machine tolerancing. Its worth it for sure, even on a stock rebuild. It reduces the frictional losses in the engine gaining you a bit more power and a more stable engine. Think if the engine was out of balance by 2 grams say, how much extra the engine will have to work to overcome the friction in rotating the crank. Quote Link to post Share on other sites
morgey Posted December 3, 2013 Share Posted December 3, 2013 It reduces vibration meaning a smoother running engine, mainly done on high revving engines as he vibration increases as revs increase (generally)In some cases harmonic crank pulleys are put on to minimise the vibration.

Chief Quimby Posted December 3, 2013 Share Posted December 3, 2013 Toyota did a good job ind first place, on stock engine it is waste of money.Are you running much higher than stock RPM limit, it is a good ide. I am running 7400rpm on my 5E with alot of boost, havnt done anything. Quote Link to post Share on other sites
morgey Posted December 3, 2013 Share Posted December 3, 2013 I agree with above, Toyota did a good job stock. When looking into building a 4age for my car, I looked over several threads about people getting there bottom end balanced and people had been to engine builders and been told that they couldn't improve on it as it was already so good.

TurboTobz Posted December 3, 2013 Share Posted December 3, 2013 Also can stop un even wear, which could give premature engine failure. Quote Link to post Share on other sites
H_D Posted December 4, 2013 Share Posted December 4, 2013 IMO balancing is a must on any engine rebuild. Quote Link to post Share on other sites
Chief Quimby Posted December 4, 2013 Share Posted December 4, 2013 Why is it a must ? Quote Link to post Share on other sites
H_D Posted December 4, 2013 Share Posted December 4, 2013 (edited) Why is it a must ? If your going to fork out all that money to rebuild an engine why the hell would you not want to balance it...as previously mentioned it can cause uneven wear on bearings and could also damage your crank shaft as well as many other problems. Like they say do it cheap do it twice do it properly and all is nice. I had my engines built by future motorsports and they balance all engines that they build and balancing is included in the quoted price. some traders charge extra for balancing but IMO balancing should be included in any engine build Edited December 4, 2013 by H_D Quote Link to post Share on other sites
Chief Quimby Posted December 4, 2013 Share Posted December 4, 2013 (edited) Well, like i postet before, Toyota did a very good job in the first place , so dont se why i should try to do it better.We builded many high powered 4agte/5efte, we never spend Money on it, and never had any problems, not even on a 4agte with 2,8bar boost and 9400rpm.

daniel_g Posted December 4, 2013 Share Posted December 4, 2013 The way Quimby does engine builds lol, wanna pikey together an engine build for a few quid, assemble it dry, FT every bolt, throw the thrust washers away, take a file to the crank and hone it with wet & dry, then on ya go boyo But seriously Nick, its best to do it right for piece of mind if nothing else Quote Link to post Share on other sites

Toyota didn't come and balance your new internals…? It was balanced from factory what 16 -/+ years ago… and if your going forged it's definitely not balanced to your particular components… Edited December 4, 2013 by TurboTobz Quote Link to post Share on other sites

Me personally I dont cut corners and dont mind spending extra cash for extra piece of mind. Quote Link to post Share on other sites
AdamB Posted December 5, 2013 Share Posted December 5, 2013 know of any places to get it done? Are you willing to send the parts away? I don't know of anywhere around London but I know a couple of places in Oxfordshire that will do it. Quote Link to post Share on other sites

Chief Quimby Posted December 5, 2013 Share Posted December 5, 2013 (edited) Well, i am not running that high rpm, almost stock,, so dont se why there should be any problem, you know i dont run stock engineWe are a few, WHO run almost same setup, we havnt ballance them, and we havent had any problem. My old 5efte have done 85000km, and still run just fine. Think that most 5efte engines dont last that long, even if you ballance them.
