Ok, im starting my project and im not sure which 13b i should go with. I know i want a 13b 4 port. either one of the old ones that come stock with 4 ports, or s5 n/a 13b with turbo housings. Im going to be going carbed as i just dont have the funds to go with a FI turbo setup. Maybe in the future i will, but for now i want a carbed setup for easy and cost. Anyway, what year 13b is the best? i want to make 200hp off a 13b with a large streetport, performance carb and a free flowing exhaust. is that possible?
thanks for any help guys.

 

it's my understanding that DFI and carb costs the same if ur starting from the ground and building up.

 

if 200 HP is your goal, then it matters very little which engine you start with. a well-tuned streetport 13B of any vintage will make 200 pretty easily (with a carbie).

however, the later, lighter, higher compression motors ('86-'88 and '89-'92) will obviously be a more desirable choice since it'll be easier to attain your goal, slightly more responsive and arguably more efficient.

 

if all you want is 200 hp, i'd go with an 89-91 non-turbo engine. they have the highest compression and should yield the best throttle response and torque for that goal.

here's a very general rule that shouldn't be followed:
(listen to what i said--then try to figure out what i meant :p)
n/a motors: the higher the compression the better.
turbo motors; the lower the better
