Well guys, just arrived from the racetrack today with some bad news... My TZ conrod blew after 1 and a half gallons. I still don't know what is the cause of this, but it wasn't overheating. Im beginning to ponder on the break-in that I gave my engine or maybe some of the racing I did with a stripped 2nd gear. Anyways, I'll be getting a Murnan TZ now and I'll be changing conrods after break-in and after each gallon after that. Very sad to finally reach the A-main and not be able to finish it cuz a conrod blew something that was never expected. Funny thing is, I already had the spare conrod on my toolbox to change it after finishing the main.

that's sad to hear, my tz is about a gallon now and still runs like a champ, conrod still looks fine but i will definately replace it after my second gallon. hey, before you getting the murnan TZ, maybe you should wait as the new OSpower Factory TZ is coming soon , it's already avaliable in japan fo rabout 30000 yen or roughly $270. looks really nice in new black head, can wait to see how it run

Just ordered another TZ at rc-toro.com. Still haven't decided if ill send it to Murnan to get it modded. After revising my old engine, I'll be getting a new crankcase and building the engine again. I already had a piston/sleeve/conrod as spare parts so the engine should be almost brand new. Im still debating if I should get ceramic bearings for the new TZ and use the stock TZ's bearings on the used engine...

Has anyone tried aftermarket ceramic bearings? How much difference in performance does it make?

Hey Riketsu, sorry to hear that, but I normally during the beraking is where most conrod suffer some damage, specially in OS engines where they are too tight. BTW you can get the TZ locally at practically the same price.

I know... But since I needed some Mugen parts anyways. Decided to order it as a whole. I still don't know if I should install the old bearings, new OS Bearings or ceramic bearings in the engine I blew on sunday...

I just ordered a 12TZ from Japan, $166 S&H included.

I was also wondering if it would be wise to put ceramic bearings in. Not for the performance, but more for durability.

They are $75...that would raise the price of the engine 50%....

There's also a $30 ceramic set....wonder what that is...and why the price is so much lower.

WHAT!!! Whats the website to that? I was checking the bearings in bocabearings. The $30 ceramic set, to my understanding, is just ceramic balls with rubber seals. The $70+ sets are ceramic balls with better materials on the rings. I think I'll be getting the $73 set since it has metal shielded bearings which has less resistance than rubber sealed bearings.

I mailed Champ RC ([email protected] ) for a quote, and this was the answer:
OS 12TZ-3port Discount price 16200Yen
Item total 16200yen
Shipping 1800Yen
Paypal 1282yen
Grand total 19282yen
This translates to 135 euro's or US$166

This is the website....but that didn't help much....my Japanese sucks.. http://www.rc-champ.co.jp/

So, would you suggest to put a new conrod in and ceramic bearings, after break-in??

Great pics of the OSspeed 12tz engine. I was going to have my LHS order me another blue-head one but after viewing this version, I will wait until it is available in the states.
