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
- SR16VE is a hot one (NEO VVL), but small displacement means it is better for parts to make a hot SR20
- 16VE N1 Autech was 200 HP stock with with 8600 RPM redline
- SR18Di was made for a while (1990-1993), but has less HP than the lighter 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 aka TBI)
- SR20De is low emissions version
- SR20DE from 140 to 169 HP
- SR20VE has 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 GT
- SR20DET from 205 to 250 HP
Swap Overview
This is one way to swap an SR20DE into a 1200 -- and is easier than most ways.
- Stock SR20DE from Silvia S13 (RWD), get complete with wiring and 5-speed
- Find the 5 wires needed to run the engine and connect them to the 1200 wiring system
- Stumpy 5-speed, swap front case with SR 5-speed front case
- Stock 1200 auto driveshaft (unmodified)
- Create Gearbox Mount suitable for Stumpy
- Cut the stock 1200 crossmember uprights, weld flat plates at an engle to it. Drill a hole for the Silvia engine mounts
- Fit a large B310 radiator or other similar shaped radiator
- Modify/find radiator hoses and water outlet to suit
- Fit exhaust (welding, tube bending, etc)
- Fit 5/16" medium pressure EFI fuel hoses and EFI fuel pump
- No need for tank baffling or swirl pot (surge tank) -- if you keep the tank above 1/4 filled
- Use skinny tires with stock 1200 diff, or fit a 1200 Ute diff (H165) for more spirited driving. Swap in an H190 rear axle assembly for hard driving.
If your government requires it, check with an Engineer before starting this project. Local regulations may require other changes to the engine as well as to the chassis.
RWD vs. FWD block
RWD SRs:
- Japan market Nissan Silvia S13, S14, S15 1990-2002
- Japan market Nissan 180SX (RS13 [S13 fastback])
- Europe market Nissan S14 (SR20DET only)
- Japan market C23/C24 Vanette - has engine configuration more like a FWD version
- Europe market Serena C23M
Crossmember
SR can use the same mounts as L-series or Z-series or KA-series. So treat the crossmember like any L-series swap.
See main article: L/Z/KA/SR Crossmember
Transmissions
SR20/SR20DET gearboxes * 5-speed FS5W71C * 6-speed FS6R92A * Automatic RE4R01A
Japan Market S15 came with 5-speed FS5W71C. Optional was 6-speed FS6R92A or Automatic.
Japan Market S13 with SR20 came with FS5W71C.
Japan Market S14 SR gearbox came with FS5W71C.
71C transmissions don't have a removable bellhousing. Instead its integral with the Front Case. 71C gearbox for other engines (e.g. KA24, CA18, VG30) can be used: by partially disassembling the gearbox and swapping the front half of the case it can be used on the other engine.
See Stumpy for a bolt-in version that fits the Datsun 1200

Japan Market RWD
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.

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.
