i think the stock Engine wich is black 1 21 engine you should change it becouse it is not really good engine and you will face problems so i suggeist that you change your Engine to Force 32 Ofna Very Happy and your car will fly Very Happy

Steve

stop right there let me tell you what to do
we already upgraded one of these before and was really incredible
1-first replace the engine with force 32 like electric said or O.S.30VG
2-replace the exhaust with JP-3 or 4
3-replace the flywheel , clutch(aluminum is the best ), clutch bell i suggest go for 18 or 19T
4-GRP offroad tires
5-proline high downforce wing

i will prefer that you use FM transmitter cz the car will be really fast and you dont want the transmission to be cut then you may loose your car

believe me you wont regret it but if you are low on budget just replace the engine with force 32 Wink

actually i dont know how much it cost but i can assure u the price is very reasonable call bu ali and ask him about the price and im sure he will give you very good price for the engine because he is the authorized dealer for force engines and ofna here in bahrain
but let me tell you force engine is not designed for buggies its designed for monster trucks like savage ,titan...etc so when you want to install it bu ali will have to make new holes in the crankcase cz the original holes distance is not for inferno engine mounts

i still prefer you install the O.S 30VG but the only problem that you will need a pump starter cz its racing engine and its not equipped with pull start like the normal engines but the force is equipped with the pull start

if your thinking about changing the engine consider changing the exhaust to and clutch bell they wont cost you alot comparing to the power you will get

give him a call when you can 39200216

Are you sure it is good to put an force 32 OFNA witch is maybe too powerfull on this car ? Should i put a 21 Turbo Nova?

Because by putting an 32cc i think i will have to change the servo ( acceleration ,brake and steering small boxes) otherwise the will problems in turning etc... Should i put Futaba servo ( box )? Is it expensive ?

Thank you by letting me know the prices and what parts should i put ( engine, servo... )

energy your car is light wight so the 21 turbo is better for your car because the .32 engine have a big amount of tourq and you dont need the tourq you need the RPM but if you are driving almost weekly and in the summer dont buy the turbo engines because they have alot of heat in them the force will be better for the summer driving

for the things you will have to change for the Force .32

1-engine mount ( if your car dont have one)
2-clutch shoes (aluminum is the best)
3-clutch bell 19T or 20T (this is the ratio) for higher speed
4-exhaust header with the pipe JP-3



for any turbo engine .21 or more (racing engines )

1-engine mount
2-clutch shoes
3-flywheel
4-clutch bell 19T or 20T
5-exhaust pipe and header JP-3 (is the best for buggies )
6- you will need a jump starter or starter box because all racing engines dont work with pull starter



about the servos you dont need new servos for new engine and new battery box these are optional if you want a better handling performance you have to install them

the price i cant tell you because i dont know all the prices


this is comparison between GRP .21 turbo engine and force .32 normal engine

GRP
Type:Off-Road Buggy
Displacement:.21 cu. in
Bore:16.27mm
Stroke:16.79mm
Engine (Only) Weight:355g
RPM Range:43,000rpm
Fuel:Nitromethane
Cylinder Type:ABC
# of Ports:5

Force
Displacement: .32 cu in (5.2cc)
Exhaust: Rear
Bore: 19.5mm
Stroke: 17.5mm
Liner:ABC Number of Ports: 6
Crankshaft: 14.0mm SG (pilot) shaft
Piston: Fully CNC-machined aluminum alloy
Connecting Rod: 7075 aluminum double bushing Claimed
Output: 3+ @ 33,000RPM Max RPM: 36,000

so now you can choose what you want to install

i think with your original engine you can go 60 to 70 KPH
with the force 32 between 75 to 80 KPH this is the maximum you can get from a nitro buggy because the buggies are designed to be used offroads when you are driving offroad you dont need the speed all you need is the tourq and the acceleration


about your brothers car im sure that it is less than 90KPH but it will go more with new engine and some new ratio setup because its and onroad car and its 2 speed !! it is designed for the speed

i hope this is answers your question
