demuire Posted June 2, 2005 Report Share Posted June 2, 2005 I don't even know what a "3rd stage head" or a "2nd stage engine" is. Everytime I think of the word stage I think of like somewhere people perform or make a fool of themselves, and rocket boosters falling off space ships...

Redwarf Posted June 2, 2005 Report Share Posted June 2, 2005 Okay. As the owner of probably the grunty-est 3K in here, let me advise you of a few things. 1: 3K's will rev, but not as high as you want it to and still be reliable. Not without an AMAZING amount of money being thrown at it. 2: Just because it will rev, doesn't mean it will drift. You need torque. Google it if you have to. 3K= limited torque. 3: Engine RPM is limited by a lot of things. Just because it will get there doesn't mean its doing anything. Research is everything. P.S: This board has a very low tolerance for drifting, unless you're very good at it. Link to comment Share on other sites More sharing options...
20V_KE35 Posted June 2, 2005 Author Report Share Posted June 2, 2005 thank mate for ur answer....but my question are:- 1. what the rev limt after tuning to 2nd stage and third stage???? 2. Can the 3rd stage head tuning be mount with 2nd stage engine tuning? (ok i notice than this forum not in attention on drifting...but the engine functional still are my best concern here) that become just this forum have info on 3k and the most important of all it ALIVE!!! :dance: Link to comment Share on other sites More sharing options...
Redwarf Posted June 2, 2005 Report Share Posted June 2, 2005 Well, we don't build engines to "stages" here. The rev limit depends on what cam you have, what valve springs are in it... etc. It's pointless having an engine with peak power at 5k rpm and reving it to 8k, when changing gears is a far better option. Unless you give us engine specs, can't really tell you anything. R Link to comment Share on other sites More sharing options...
20V_KE35 Posted June 2, 2005 Author Report Share Posted June 2, 2005 yes i understand what ur saying.....but i need it cause while drifting (beginner) usually used 2nd gear and rev it high...so i got want ending up blowing my engine...(It a long way home). talking about spring....it say used dual spring...what is the cheapest (part from junk yard) will fit this??and don't forget the rockers seleeves too? sob Link to comment Share on other sites More sharing options...
Redwarf Posted June 2, 2005 Report Share Posted June 2, 2005 Your valve springs should be matched to your camshaft. In theory they only need changing if you have more than .400" lift at the spring. I'll say again, unless you give us a good idea of the engine specs, we can't tell you a suggested redline. Link to comment Share on other sites More sharing options...
20V_KE35 Posted June 2, 2005 Author Report Share Posted June 2, 2005 ooo...ooo....something ring my bell...had anyone (u guys) try accordingly to the tosco manual...or u guy just self tuner??? Link to comment Share on other sites More sharing options...
Redwarf Posted June 2, 2005 Report Share Posted June 2, 2005 Apart from the TRD boys, I don't think anyone in here has ever seen a Tosco tuning manual. We all self tune to the specs of the engine. Link to comment Share on other sites More sharing options...
blown 5k Posted June 2, 2005 Report Share Posted June 2, 2005 I`ve pretty much got all the tosco/trd manuals a good guide but thats about all as the parts are no longer made. Link to comment Share on other sites More sharing options...

Super Jamie Posted June 4, 2005 Report Share Posted June 4, 2005 the tosco manual has been out for many many years, these days we know how to build BETTER, more reliable and torquey motors than the tosco 3k, and for less money you can certainly follow the tosco manual if you like, but you're best to look around at all the available tuning options and take ideas from everywhere to make something to suit your requirements. for example, the head porting in the tosco manual is excellent, and twin sidedrafts are how you make max power with carbs, but the tosco cams are pretty crap if you can get a 4k engine, start with this, the increased stroke gives the motor the ability to make quite alot more power. if you want to stick with the 3k, use a 20-60 cam with anything over 0.400" lift, this is about as powerful as you can make a 3k without sacrificing torque, and having to strengthen internal components ($$$) or rebuild your engine alot because if breaks ($$$) if you use a 4k, i'd suggest a 25-65 cam but there are other grinds people are using as well Link to comment Share on other sites More sharing options...
