The 7 port turbo's put out more bottom than people think, we ran them in truggy for some time, i have a vid of the prototype OCM truggy running one of my 7 ports and it looks great, we ran JP3's and 053's in truggy, and 2 1.1 and 1 1.0 for clutch, and it will flat out move, i assume they are even better in todays truggy, and very nice topend revout

Grab the 5 and don't look back, you will be very happy with that set up, you said you have a Kyosho, it will toss that thing around all day.

not that the 5 has to much bottom, but to see if the combination of the mod work, combined with the top end of the 7 port, how it would fair in truggy. I think it worked out pretty well

In my opinion, a 5 port turbo is the way to go for truggy. It has wicked bottom end torque which is really beneficial if you run on smaller technical tracks with short run-ups. You can tame down the torque of the 5 port by adjusting your clutch set-up and running a 6.5 to 6mm venturi carb restrictor.

The 7 ports has good torque and the power is more linear. If you are running on large, wide open tracks then this engine may be a good choice.

If you are having trouble deciding, you can always buy both the 5 port and 7 port 21

I have a question for you guys. I have an old novarossi plus 21-5 that had a rear bearing let go on me awhile back. Lets just say the piston and head button don't look new anymore lol. However the crankshaft, crank case, and carb are all fine still. I have been thinking about buying a go tech 5 port piston, sleeve, rod, and head button for it, as well as a set of tko ceramic bearings. My question is would the go tech stuff slide right into the nova case and crank? I checked the bore and stroke and it is the same with the go and the nova. I can get all of the parts for around $150( alot cheaper than the nova parts) so i think it is worth it. My thought is that with the go p/s/r and the nice nova 21-5 crank the motor should produce a nice smooth, powerful powerband. I am just wondering if all the parts would lign up? I believe I heard somewhere that the go was actually modeled off of the nova, atleast the P/S/R was. Brian do you have any idea as to wether it would work? I just thought it would be a fun thing to try with a motor that would have been a paperweight. Thanks for any help.

PM 22racer. He has successfully used Go Tech parts in Novarossi engines. I'm sure he can answer any of your questions.

086 pipe is better suited for the 5 port especially if you are on a budget. The OS 2060 and Go Tech 0801 are good also but the 0801 is thinned walled and dents easily.
