With this I was able to design an adaptor plate and engine mounts which were laser cut and welded together. Sadly I seem to have lost the photographs of everything being digitised. I also took measurements from an MG front plate for the engine mounts. The plan was to design a simple kit that would use the original gearbox, clutch and engine mounts so no modifications would be required on the car at all.Ī bare CG block was bought on eBay and digitised on a CMM along with the bell housing of a spare Midget gearbox.

The conversion has been popular for ages with Minis but I could find no evidence of a rear wheel drive install so set to work. As an added bonus even the capacity is a-series (9). nevskills532 and I spent a large amount of time getting the head flat again on a sheet of glass and repaired the radiator but my dad was never that confident with the car again.Īfter considering rebuilding the engine a plan was hatched to retrofit an a-series derived Nissan CG engine which would offer reliability (yes, an a-series can be very reliable), increased performance and a bonus reduction in weight all in the same package space.

The front suspension was also given a refresh at a 'specialist' garage who blew the head gasket, warped the head by 10 thou' and cracked the radiator after leaving it running with low coolant for some time. The distributor had to have a repair where the die casting had collapsed allowing it to move in the clamp. The engine was very tired indeed so was treated to a standard unleaded A+ head after a compression test gave low readings which were unaffected by oil in the bores(thank you Metro!). Out for a winter blast over Ashdown Forest It and has lost the original steering wheel and mirrors but has clearly been looked after. At some point the car has been repainted and restored to a fairly decent standard. It's an early 948cc GAN/1 car with almost all of the original features intact including the original engine and 'smooth case' gearbox.

N = 2.10 + (0.52 – 0.30) = 2.22 mm, so we need a valve lifter with code TS222.Several years ago my dad bought this rather nice MG Midget. Standard type: NGK BKR5E-11 Hot type: NGK BKR4E-11 Cold type: NGK BKR6E-11Ĭalculate the thickness of new adjusting valve lifter so valve clearance comes within specified values.

lbĬompression differential limit between cylinders.

Head tightening procedure and torque specs: The CG13DE engine does not have hydraulic lifters, so special valve lifters are used to adjust the valve clearance. The CG13DE has the same valves as the CG10DE engine, but other camshafts. The exhaust valve diameter is 22.5 mm (0.88 in), the duration is 22°. The intake valve diameter is 27.5 mm (1.08 in), the duration is 222°. The camshafts are driven by two-timing chains. The Nissan CG13DE engine has a dual overhead camshaft with four valves per cylinder. The cylinder head is made of strong, light aluminum alloy which gives it good cooling efficiency. Number of piston rings (compression / oil): The crankshaft main journal diameter is 44.97 mm (1.77 in) and crankpin diameter is 39.97 mm (1.53 in), center distance is 42.0 mm (1.65 mm). The connecting rod center distance is 120.7 mm (4.75 in). The CG13DE motor has two compression and single oil control rings. The cylinder bore is 71.0 mm (2.79 in), piston stroke is 80.5 mm (3.17 in) and compression ratio rating is 9.5:1. The Nissan CG13DE has an aluminum block with a five-bearings crankshaft supported system. General information Engine Specificationsġ04 N⋅m (10.6 kg The breakdown of the engine code is as follows: The engine has on 9 mm shorter connecting rods than CG10DE.

Cylinder bore and piston stroke is 71.0 mm (2.79 in) and 80.5 mm (3.17 in), respectively.
