Ok so i have a 1994 del sol s model with an ls motor swap. now my ls is getting tired and its time to swap it out and i'd like to go with a jdm b20b motor, how hard would the change over be and what would need to be done besides just pulling my motor and swapping the tranny to the b20?

 

?

 

It will b the exact same thing, there is no differance in the B18B and B20 except the bore of the cylinders.

 

Not hard at all. its a b series. same hook ups

 

The B20 isn't that much bigger and won't make much more power. Either turbo, or get a bigger, like 2.2L+ engine.

 

direct swap but you may have to reuse your ls intake manifold

 

alright thanx but someone mentioned something about the distributor because they said the b20 is an obd2 motor? is that tur because my ls is obd1

 

good luck with the swap!

 

So u just use the dizzy off ur B18 engine on the B20

 

And like someone else said, you gotta use the LS intake manifold

I'm doing same swap from b18 to b20 but in an ek

 

yup, because the B20B intake manifold is to long, sits up to high.

 

ok sounds good thanks my motor is getting tired and i can get a b20 cheap so when income tax comes in imma get it

 

so the b20 being obd2 will it work with my existing wiring harness?

 

Like stated above, interchange the parts from the ls to the b20 block.

The car will definitely pull compared to the ls. 2.0 liters is a big difference in torque wise. Besides the b20 torque curve is pretty flat so its good for daily driving. If you get the 99-00 model jdm b20b, the the horsepower is more than the ls. 146hp.. and more torque

 

Curious does it need to be timed or mapped or anything I swapped my b18 to a b20 and had the same problem w the hood but now the cars been bugging out and turning off assuming the air fuel isn't right
