Has anyone had and problems with the main bearing in the TZ series. Just a question? I know in the 21VZ II the rear bearing can be susspect after a few litres after break in.

I'm running the first one here in WA and after 3 litres it hasn't shown any sign of any problem yet. I'll be sure to post if I experience any problems.

Whats the top end like with the TZ 3-port. A mate told me it lacks punch down the strait, but he is biased to Nova so

find your self a heat gun or a hair dryer and heat up the block to heat it up as much as possible.
I've used the wife's hair dryer for this in the past and if your not in a rush it works takes a few min to get it up to temp.
Had a buddy who couldn't wait the 3 - 5 min and used a small butane torch with a heat gun type attachment to heat up his block worked good but killed most of his butane charge, that and you have to be very careful with it, blasted thing gets friggin hot.

loosen up the glow plug and turn it over then slowly tighten it up.

Me personally I like the heat cycle method myself. IMO it seems to keep the pinch longer and produce more power.
but I haven't done any scientific comparison tests

The engine is absolutely screaming, but the speed is normal and nothing special. I guess i just fooled by my own ears

there are several variations but I do it this way.
heat up the block to at least 150 f
start engine in car and drive it to get the temps up to a min of 210. not driving it hard but going thru the full range for about 3 mins
stop the engine via the flywheel and make sure the piston is at the bottom of the stroke and let cool for 5 - 10 min.
ReHeat the block to 150 f and drive again for about 3 min going thru the full rpm range.
stop via flywheel let cool with pistom at bottom of stroke

I repeat this procedure for 3 full tanks (75cc) then I start to tune for power as normal. I've done this to 4 engines so far and not had a single problem yet. I have a picco .26 that's about to hit the 14 gallon mark that I used this method on and it still has pleanty of compresion left. I did 2 .12 and they both scream they both have just over 2 gallons on them and the fourth one is still in the process of breaking in

Zoom, I'm not talking about other engines here.

Anyway, along with the break in method, mark where your flywheel reaches TDC- it helps during the break in. My LHS should be getting them later on so my friend can get one in his NTC3 so we can run together.

Ran 12 tz for the first time this weekend.Was easy to tune and the performance was great.Good low to mid.Topend was super.
When the car would shift to second it was goodbye.All types of

My 6 OS TZ's arrived in just 4 days from Champ.... they are great...... bit expensive on the shipping and bank charges......but all fades away when u see the engines!!

why 6? well one for each team member of my team. We all got RRR's and K3's and Fantom.....yeah we all just got really involved in Racing !! and Imagine from Jets to Cars...... lol

All RRR's will have the OS TZ in it. Except for me It will be on my FWo5RR.

Just a quick qs. though How does the Skyline Pipe work on this. the fat outlaw......
and the normal OS pipes ?

or do i need to get a turbo pipe ?

Cheers

I don't have a TZ but Skyline pipe is the best I know for the FW05RR and I've tried many different pipes.
