Danny-B- Posted January 6, 2008 Share Posted January 6, 2008 Should say something on the side of the crank case, but what car is it from ? etc etc more info would be good. Quote Link to comment Share on other sites More sharing options...

jammybiffa Posted January 8, 2008 Author Share Posted January 8, 2008 Thanks for your help Had a look on the crank case,can not see nothing unless its behind the engine mounts (bottom of crank case)will investigate. Its out of a hyper 7 Thanks james Quote Link to comment Share on other sites More sharing options...
martin Posted January 8, 2008 Share Posted January 8, 2008 I might be wrong but if my brain serves me right im sure the 4.1 has the same block as the 3.5 and i've seen it on the net saying although the block says 3.5 on the casing it is a 4.1, so obviously they have made the sleeve thinner for a bigger piston. As i said i might be wrong but im pretty certain im correct. marty Quote Link to comment Share on other sites More sharing options...

jammybiffa Posted January 20, 2008 Author Share Posted January 20, 2008 I just received a new 4.1 in exchange for a my broken Hot Bodies engine, and it has the same purple head as yours, If that helps. Thats the problem,i brought the car second hand & it was advertised as a nitrostar f3.5 engine. I have been on HPI website & it looks nothing like it but it looks the same as the f4.1 So until i work out which one it is i can't order the part i need Thanks for the reply tho Quote Link to comment Share on other sites More sharing options...
