The SR20 can bolt-in to a Datsun 1200 without cutting the firewall, though it's easier with an original automatic-equpped car (which has a bigger central tunnel). The 1989 SR series is considered to be the replacement for the 1981 CA Engine based primarily on NVH improvements. It is heavier and bulkier than the CA series, but the SR20 puts out more HP than the CA18 or CA20 engines. In most Australia states, 2-liter is the largest normal engine swap into 1200, so the SR20 naturally aspirated is the ultimate capacity swap. In North America where there are no laws limiting capacity swaps, the KA24 is a more popular swap due to the larger CCs, higher horsepower and higher availability.

Overview
- SR18Di was made for a while (1990-1993), but has less HP than a GA16DE engine -- see GA Engine Swap
- SR18DE made 125HP, but is much heavier and bulkier than CA18DE 131 HP
- SR20Di only 122 HP (single-point Fuel Injection)
- SR20VE is the hot one, with NEO VVL variable camshaft timing and lift. Unfortunately it was only available in FWD vehicles.
- SR20VET has the most HP (280HP) and was available only in the X-trail

Vanette is similar to the FWD SRs in that the distributor is on the back on the cylinder head, and the Throttle Body is pointing back. Because the engine is mounted under the floor, there is no firewall to foul on.

Some guys at Ozdat swapped an SR20DE into a 1200, costs were $1400 for the engine swap part, $2000 total including the car.
