car wont warm up and bump idle
 

i have a stock 86 rx7 and i have a problem when i start it up and warm it up for like 10-30 min driving around my area the temp needle stays at cold and barely moves up i seen alot of 7s out there and its always in the middle is it a over cooling issue?? or wat!!! also i want to buy a jdm t2 tranny but i was wondering will it still have the same shift pattern as a left hand drive car or what? thanks

Your S4 temp gauge normally runs at about 1/4.
S5's run at 1/2.

Shift pattern is the same whether RHD or LHD.
