ok so i recently aquired a b16 hedad and supercharger setup... i have a B18C1 in my car right now. i pulled the head, put the b16 head on torqued head and cam caps down to spec, but when trying to rotate the assembly, i cant get the crank to turn a full rotation... its stoping about 15 degrees from being TDC.. is there anything im doing wrong? and anything in specific i need to know that deffers from a gsr-lsv-b20v setup? ive done all three of the previously mentioned but having issues now

thanks for the help HT

 

Sounds like the timing is off! The valves are probably hitting the pistons and stopping the crank.

 

ok i have the motor together, fixed the issue of rotation it started just fine... no leaks but a very rough idle, i understand it needs a tune, but im have park plug issues... the gap on my plug on cylinder 1 is getting pushed down (or up)/ the gap is getting pushed completely closed...WTF any ideas?

 

Make sure that plug has its crush washer. Also make sure that plug is the same size as all the others. You might want to have a look at the valve clearances to see if there's a bent valve crushing the plug.
