Alot depends on what your looking to do with your Baja there are so many combos thats its hard to just pick one and say its the best.Raw power,top speed the list is huge and getting bigger all the time.
Try looking at the Reed ported Engine from O'Neill brothers.
A Reed Engine is way better than most other tuned engines, unless you want to spend US$ 1000 on an Oddified Heli Tune.
Off course, if Money is No Object, then Oddified has a Heli Tune with NOS, making a documented 8.1HP with a 2.5HP NOS Nozzle. he also has a 5HP Nozzle for it... but price is most likely in the US$ 2000-3000 range.(he has offerred the Prototype for sale at reasonable bids, don't know if it has been sold yet)
Thanks for the info. I think 8hp may be a little extreme but would be fun to try to control. I just want something that will push the limits of the car. I hate it when the car can out perform the engine.
Alro do a 26cc engine which is giving out 5bhp so add a good pipe and filter and you got more! £330 not sure what that is in $ sorry guys but there is loads and loads of all round power and i belive he will tune it for what you want it for!! Hope this helps?
The CY engines are fine, i have 3 of them, NO problams. I certainly wouldn't be affaid of getting one. There is some on fleabay right now, starting bid $150 for a chromed out 27CY or a 29CY.
