Finally got my car to throw a CEL today.

The cars a 98 dx hatch with obd1 b18b swap.
Car seemed to run fine when i first did the swap and now is acting up. If i drive the car in between 4 and 5k it will missfire like either spark or fuel is cutting out. The car wouldnt throw a cel at first so i replaced fuel filter, plugs, wires, cap and rotor to see if any of that fixed the problem. Then i retimed the car. Then thinking the fuel pressure was falling off at said rpm i ordered a new FPR and high flow rail. I havent gotten the fpr or rail in the mail yet. But today it threw a code 7 and 43 while i was driving to get smokes. Im just going to replace the tps but im going to buy a new TB at the same time. Im also going to replace the 02.

So now my question is what size TB would not be over kill for my b18b. I do plan to boost by the end of summer but am unsure of what size is ideal.
