I don't understand why someone would buy a B3 for $200, spend another $50 to $70 for a carb, spend another $20 for bearings (after the stock ones fail at 2 gallons) when you can buy a high quality race engine like a P-5X, P7-R, S-5, V-Spec or something like that for only $30 to $80 more.

Werks engines have an excellent rep for durability and the carb talk just isn't true. The 1st gen carb (first run of gold heads) were finicky but they are as good as any carb on the market now. The bearings? You must be thinking of OS V-specs.

the carbs on the b3's are not working right at the moment(have a friend that runs for them confirmed it). I have run RB S3's in the past and love them. RB's last a long time and once they break in (about 2 gallons) they will scream.

Thumbs up

The original Works engines had carb issues. The new ones seem to run very well. They are crazy fast.
I'm an RB guy. I can honestly tell you the S3 was not ment to run in the same league as the B3 from Works. Now you do a little modding and use the proper pipe and you you will be right there.
The RBs use Nova carbs and bearings. Nothing but the good stuff.

Sportworks motors ar just as good as any of these. I'll put them to the test with these motors any time. BTW - we do it every week.

JPX - 21 - is a P5 motor. It runs the same and has the same durability.

The S3 is smooth and will not get you in trouble on a small track. It is all about the pipe and header. Later you can cut it if you want more out of it.

The B3 is hotter with more bottom end punch. The new ones are very good.

I was very pleased with the b3 until it started the hot starting problem. It seemed to out pull everybody else on the front straight. what is causing it not wanting to start when it is warmed up? I am talking like 200 deg F. I have tried about everything. I use a novarossi plug cold. I tried the next step up plug, retuned the carb. resealed the engine even though the engine has orings through-out. I just gave up and decided to try the rb s3.

I say go with the RB. I just got one of these not long ago and it rips for teh money. Its not the fastest motor out there but its smooth and I think that counts more sometimes. Ive been running it with a JP3 pipe getting 8-9 minutes on a pretty large track (and a heavy trigger finger). All that said plus its an RB so you know it will last. :

The JPX-.21 is based on the Picco P7R-EVO2 engine. It is supposed to have a little more bottom end than a Nova P5 and a lot more top end. It is probably a steal at the $229 I see it advertised for. I believe you can also get the Picco P7R for that price at Nitrohouse.

I like the Novarossi 086 on the B3 engine. That engine needs the most help on top end which is what the 086 does. The 053 will smooth out the powerband a little which might be good on a slick track. I would expect the JP-2 to also be good but I have never tried it.
