that engine blows ballz no kidding better off with a lrp or picco or surefire or something else

 

[609savage]

is the surefire rr a better deal..I'm looking for atleast a .28 or bigger...

the only problem with LRP is apparently its getting really hard to get parts for if you want the exact duplicate pretty much go with the xtm 457 pro truck engine it has the same specs as the lrp and looks the same and goes for around $160.00!! and still can get parts everywere for it.. i have one and man all i can say is its a power house of a engine!! it has a claimed hp of 3.8 which is insane!! wheelies on demand all day long lol or i've heard the surefire 32 is a awsome engine as well!!

 

[BIGDAN89]

isnt a lrp a 8 port and the xtm a 6 port

The LRP Z.28 spec3 may be hard to get parts for but I love the power and will just run it till she won't go no more!
