need some help here i have an ofna ultra gtp that came with a .26 engine,after many runs, the engine is tired. i bought an offna picco .27 for it,but now im finding out thats a buggy engine. ofna said no problem,it will work fine. but the exhaust silicone gasket that came with it is too small of the stock pipe that was with the .26,and the gasket that came off the tired .26 is too big to fit on the port of the new engine any help please?

i would go with a nice .21 race engine, they make tons of power and will rev a lot higher than a .27 will

Not to make an arrgument but I heard that the new Ofna .28 pro will rev at bout 37,000 RPM's.

ya and a good .21 race engine will more then 40,000rpms and of the race .21 can make 3hp.. if you don't have the money for a good race .21 that picco will do fine and your car should be quick

Just remember to gear the car up and or invest in a two speed. Onroads are different that offroads and due to the difference in wheel sizes you'd have to gear accordingly. Purchase a new gasket and you should be good

BTw a good race .21 onroad will cost you $380-$400 bucks...so don't bother.

ohh sorry i never read that right, so your saying you exhaust won't fit right. can you take a pic of the problem, you might need a new manfold but i am not sure what going on. Big block engines should have the same size exhaust port. soory i read that wrong[:@] from what i have heard some force engines use a different exhaust size so you probaly going to need gasket

thanks alot for the info,yes,the picco .27 has 3.1 hp,revs at 34,000. ill go to lhs today and get the right gasket and or header pipe.i think it will go good. thanks for all the help.
