I hate to keep saying this... but unless you've seen the new OS-TZ .12 3P run, you really can't pass judgement... When the NS3 came out a couple of years ago... That was the best motor bone stock out the box your money could buy... The new LL ns3 is a nice motor and I won't say it's not... but the TZ 12 is not a poor Man's Nova... It's a true MONSTER on the track.. Maybe it's just mine and the pipe I'm using, but My TZ-.12 3P has no problem what so ever with running against Collari's, EVO II & III's and current Nova based motors on large size tracks... That being REV and Crystal park out here in SoCal... It's funning when peeps ask me if I'm running the TZ-18 and I tell them it's the .12-3 port bone stock with no mods... I'll say this though, I've seen 2 TZ 5 ports that weren't as fast as my 3 port... Could have been there break in was not done correctly or the tune pipe they're using... Just today, one guy had the 5 port with the most current Skyline pipe and his still could'nt touch mine... Hey, if you got alittle extra money to spend and you like Nova based motors... Get it... But if you want something different that can not just keep up but spank the competition... You can't go wrong with the New TZ-12 3P... I've had the NS3, TSR3 & the RB V12... Each one costing over $250.00... And let's not add the cost of replacing the piston and sleeves...
I just picked up and extra piston/sleeve and crank for my TZ-12 3P all for less then $75.00 to mod and put away when my current pieces wash out... Oh, and you get a 2 year warrenty on the stock parts too... Ok... but you all can see where I'm going with this... You can't loose with the TZ-12 3P both in cost and performance... Oh, if anyone is thinking about getting the TZ-12 3P, use either the Yokomo Mielke pipe, the Mugen racing pipe or any top end Nova based pipe to get the extra RPM's out of the motor... The TZ-12 3P is an RPM motor and make most of it's torque and power past 30,000 RPM's unlike the prior TR line that was mostly torque and so so on the power... I guess you all can see I'm happy with TZ-12...
