Revision as of 10:02, 21 February 2012

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.

Richard Swap

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