Is there a big difference between Vitos 240 kit or just getting an LA Sleeve and a wieseco 240 piston. I know Vitos comes with some porting and head work, but besides that would I really notice a difference.
Putting a bb sleeve in a stock jug is no good IMO.The vitos bb kit has a 12 port design which stock cylinders do not.If you are looking to spend less and save a few have your stock cylinder ported and if money is available get a 3mm stroker crank.Just remember a ported stock cylinder will outperform a unported bb cylinder any day.
