Default difference between 3 and 5 port engines?

Hey, Im looking at getting an Associated TC3 kit and i was looking at engines. i was just wondering what would be the best engin and what is the difference between a 3-port and a 5-port? also is the TC3 a good choice.

P.S. I also have an Associated RC10GT that needs a new engine...what would be a good one for that?

3 ports are race legal an 5 ports aren't (there are exceptions). in theory 5 ports should be faster but since they aren't made for competition and for that reason not tuned to the max, the difference is hardly noticable.

im looking at the O.S. .12 TZ (P)-T 5-Port Turbo...It says its race legal?

but if 5 port isnt race legal there is that same engine in a 3-port.

When it comes to on-road racing budgets are usually the factor deciding what engine you buy. IF there is an exception to that it is the OS TZ engine. You get an engine that is definitely faster than what you pay for. What the other guy said is correct. If you race using roar rules, you need to get the 3-port engine. Have fun!!!

Except outlaw class...which usually NOT a typical RACE class unless you are running 235mm chassis or use the LOLA type over 200mm chassis, if there is that class, you can use 5 port engines.

Overall, get the 3 ports for the NTC3....12 OS TZ is a good choice.

You got to run fast and you got to run hard if you want to be ahead of the pack during competitive on road racing. A good mill is just as important to have as a well tuned you car. A NEW O.S .12TZ 5 PORT turbo engine. If you want power at the trigger, the TZ 5 port may have exactly what you need.

ok...ill look into both then...also is the TC3 the bst out there (in your opinions) that is shaft and not belt...does the TC3 have a closed gear box, cause i drive mostly on the street and there are some little rocks and stuff.

NTC3 is the best choice for bashing but definately not the best choice for racing. It will do OK on the shorter tracks but will get BELTED by the belt drives on longer tracks. If your serious about racing, MTX-4, V one RRR, or Serpent 710 !

p.s. OS 12TZ 3 port is great engine for the money. It doesn't give much away to the top end italian engines! It has a nice powerband and is one of the most torquey .12's money can buy! Rebuilding is also easy on the wallet!

I'd suggest the Kyosho FW05RR or FW05R even for bashing. Its very strong and handles great with out-of-box setup. I could say its as strong as a Mugen MTX-3. A NTC3 I would rank it on the bottom of the list when it comes to toughness.

toughest shaft-powered, has to be the FW-05RR. toughest belt-powered, has to be MTX-3 or maybe MTX-4 too.
