Hi guys new to this forum Iam over in Scotland... Being looking at buying a blaster engine from America can pick one up for around 300bucks which is around 210 pounds. What should I look out for when purchasing? Iam going to rebuild the whole engine change everything I can so that's not a problem is there any big look outs tho? Also would a 2000-1988 engine fit in the newer model blasters thanks!!
