Default Piston/Conrod/Liner for Novarossi N21BF

Hi
Please can anybody advise on the best Piston/Conrod/Liner for Novarossi N21BF. If so please give details including part numbers etc. The engine is installed in a Kyosho 1/8 mp7.5 buggy, More power would be nice without losing out to much on run times. A friend just brought this vehicle and has been had over as the engine has poor compression. If an upgrade is possible please give details.

Thanks guys

Default Here you go...

Here is the whole set. It's the con rod installed in the piston, and the sleeve.

It makes life so much easier to buy it like this, however, if you need help puting it together or want the engine checked over, you may need a new front bearing for example, you might want to contact Monty at Houston's engine Service. He is a real nice guy who specializes in Novarossi engines.

part# 08536 would be the 5 port upgrade , around 150$ and i believe the part# for the 3 port is 08590? around 110$ or a whole new n21r limited for 135$ plus shipping

I would put an Alpha F850 p/s/r in it for $76.00. It should have more power and great quality.

Not uninteresting - is the F850 a copy of the N21? Same bore, stroke, rod dimensions, timing and all???

Thanks,
Paul
