I'm leaning toward the 5-port, though I don't like the silver head. If anyone wants to swap for a new blue 3-port head...

A 5 port should use more fuel. The big reason for choosing a 3 port vs a 5 is if your racing runs by roar rules, or if you ever plan on entering a roar race. 5 ports is not legal in roar racing.

Personally for 200 more, it should be on a COMPLETLY other level of performance, but from what i hear, it really isnt.

i run a ostz in our tracks. our tracks is a mid-sized track. one of the racers uses a rody x12 tuned by rody. not much difference in the straights

this engine is a screamer...

cool. Ive done alot of "pre shopping" trying to determine what my next car would be. Ive decided on a r40 w/ a 5 port tz, i heard the tracks im going do dont restrict ports. All i have to do is save up now but i cant wait

. I was going to buy the os exhuast, is there an exhaust that works better than this with this engine?

R40? Be sure that car is used alot in your track, so you can get alot of support on settings and tips. The R40 is known to be heavy so I dont know if youll see the true power of a 5 port TZ on it. I would probably recommend a Kyosho, wether its belt/shaft, since its one of the newest car on the market.

Jye, if you want the most power, torque and RPM's out of your 5 port TZ, go with the Yokomo Mielke pipe or any Top end Nova based pipe like the Mugen racing pipe... The OS pipe is ok just as is the Skyline pipe, but if you want most power out of that motor, strangely... I've found that the Mielke pipe is the magic pipe for that motor.... And I've tried 6 different pipe setups just to see... ie... Skyline, RD's, OFNA MEGA & the OS... The 2 pipes that made the most power for me were the Yokomo Mielke and the Mugen racing pipe... Running 30% nitro and OS P7 & P8 plugs... I'm running the same same P7 plug going on 3 weeks now and it still looks almost like brand new... I know that's off topic, but it just goes to show how well the motor holds it tune....

OS manifolds

The inline and non-inline manifolds are shown here, what's the difference between the two M1001 SC and M1001??

Great engine. My buddy broke his in yesterday before the races, so it had like 5 tanks through it, still quite rich, and was hanging with every engine on the track - this is without the ideal clutch setup also. I thinks me will get me one. Air density was 8600 ft, running 30% with both shims , and a os 7 plug, with temps just reaching 220. Can't wait to see what it'll do if we lean her out a couple turns!!!!!!! Always OS!!

I just ordered a 5-port TZ from rc-toro.com ($197.25 shipped) and I am excited to get it in the car.

I am not a big fan of the silver head, though. If anyone just bought the 3-port and would like to trade for the blue head, I'd trade them straight up. Just PM me...
