I could use some help from all of you Pro's out there. I am trying to find an engine for my buggie. But I don't race I just bash. I have chosen the following engines, so can you give me real world opinions. I want smmoth power, Reliability and easy to tune. I hope that is not asking for too much. When giving your opinions I also want to know that parts are readily available for the engine. I will be using a Jammin JP2 Pipe and the clutch that came with the kit.

1. RB concepts WS7 2
2. RB S7
3. Novarossi P5
4 Novarossi S421B
5. Collari LC21B7

Thank you to all in advance for your help.

I did searches on this site and foud a few answers. Can anyone give opinions?[]

Those are ALLL really good choices- take a stab at any of them.

What about the V-spec?

V-Specs OK- but nothing special. I'd stick to the Novarossi Based motors ie. Top 4 on your list.

Any opinions other then they are all good. How hard is it to get parts for these? I am hearing the easiest is RB.

I'm going with an RB WS7 II for my SP1; however if your willing to sacrifice some of the WS7 II's performance for a smoother running easier to tune engine the S7 II is a very good choice too.

What do I lose in performance? Can I beat my buddies Tmaxx with a OS.18tm?

I got WS7II and MAX M8. I think 421B more or less similar to MAX M8. My buddy runs V-Spec. V-spec linearly puts down power so for smooth driving. M8 gives fair deal at bottom end but becomes a screamer at top end upon a 100m straight for 3 sec orgasm. WS7II is a screamer all the way through.

ws72 and never want another engine again

How much of a difference is the S7 to the WS7 II?

take it from a ws7II owner buy a jp mod motor

Well I have a S7II on the way already so I will have to see. I don't race I bash. So I think I will be ok.

How about that Collari motor? How do they run?

what about the jp engines and maxpower
