Default JPX .28 vs Picco p3 .28T

I seems that both of these engines are made by picco and distrubuted by ofna. I am quite stumped on which one is a better choice, I will be basing my decision purely on performence. It says the picco p3 is a 9 port, it says that it is a 5+2, so that means it has 5 intake 2 bypass, and 2 exhaust right? Well I have also read that the JPX is a 5+2, but it also said it has 3 exhaust ports, and that is supposed to help with top end. Does that mean that the JPX is a 10 port design. If so it would be the obvious choice considering it is not much more expensive then the picco p3.



All comments are greatly appreciated,
thank you

go with the cheapest one you can find as I believe both are the same except for the head, but I could be mistaken, wait for Maximo to reply, he's pretty much the Picco expert around here!

I would like to know if these engines are different. I find it hard to believe that one distributer (OFNA) would sell the same engine just labeled differently.

they are basically the same.....the Jammin had has Minor tweeks to the Timing #'s over the last year or so......but for the most part these motor's are identical except color and head config.....another thing tho is the Jammin Does not come with a Pullstart Nor can you buy a Pullstart jammin...you must convert it.

the jammin is more a Truggy motor....the picco a MT motor.

Description: High performance .28 size racing engine for 1/8th buggies and truggies. Special attention paid to the details that are so important for off-road R/C racing. Such as durability, ease of tuning, and driveabilty. Tweaks to the materials, crank timing, and tolerances all played a part in getting the engine to the high performance edge that Jammin Jay requires. This engine delives excellent bottom end power with great top end run out. Iincludes Turbo Plug type heads. The .28 is all out big block performance but still very easy to drive and gets surprisingly good fuel mileage. Turbo Glow plug included. Made in Italy

+1 for integra. The jammin and the picco take the same piston sleeve and rod.

the JPX has less crank duration then the P3 28 FTT...they are identical in all other aspects...the JPX will make slightly less power, but get better run time and smoother power...

I have driven both engines.. i have to say the Picco P3 is way more motor.. thing is nutty on the bottom and i can get better milage out of it.. My truggy was pulling wheelies when you hammer the throttle hard going into a straight. The Jammin is a little smoother of power delivery on the bottom but then screams when you hit the high end of the RPM range but tends to be a bit harder on the fuel. But with the cost factor added in the Jammin would be of the better bet.

Well here is the real question... I've beel looking at the JPX for my Truggy should I go with the .21 or .28? The track I run at isn't real big and only has a small straight for full speed.
