b18a/b
i've got a 93 teg with a b18a (obd1), i just blew my engine and have found some good deals on newer b18b's, also meaning it would have lower miles, if i swap my b18a for a b, do i have to change my ecu and harness also, or is it a direct replacement?

Re:b18a/b
if you get a 94/95 b18b, you should be able to just use ur stock harness/ecu and not change anything - at most, you will have to switch intake manifolds or lengthen a couple of wires (I think a couple of sensors are in different places). If you get 96+ , you will have to change the Distributor and Injectors to OBD 1 equipment cus the plugs will not fit the obd 1 harness. You will (99% sure) be able to use ur stock ecu/harness on both though.

hey projekteg, if I were u, I would try to tear down and rebuild the motor. for the price you would spend buying new motor, you would be able to get some nice internals and crank up the boost/nos/whatever u use... I've seen it done on hydrolocked engines before even if u just tear down and rebuild stock...
