4.5 litre JE 'Clubman' Engine

When replacing a fuel injection 3.5, 3.9, or 4.2 litre engine, JE strongly recommend
the use of our 4.5 litre version, this uses the original 94 mm bore (3.9 or 4.2) with a
specially made 80 mm crankshaft.
Including: block, crank, pistons, rods, camshaft and lifters, vernier/roller-chain cam
drive gears, all fully balanced, oilways in the block cleaned and improved, selected
rods, lightened, and race-standard prepared with JE 101 cam.
Ex-works:                                                                   £3,490.00 

 

Stroker kits for Rover V8

There are 5 kits of parts available to allow a customer to increase the capacity of his engine by increasing the stroke alone. In contrast to other kits on the market, our rods are lighter and less bulky at the big end, so the overall package is nearly 2 kg lighter and does not require any metal removal in the crank-case to fit the parts.

4.8 litre kits
A balanced set of crank, rods, and pistons, all balancing done in house.

Specially made connecting rod, unique to JE Engineering. It is significantly longer than the old standard 'classic' rod and therefore makes the piston shorter, reducing weight, while also reducing rod angularity as the crank rotates, reducing piston side loads, and making for a smoother running engine. The rods are forged from 4340 steel, stress relieved, shot peened, and crack tested.

The crank is tuftrided and polished, stroke is 86.3 mm.

Pistons for 94.0 mm bore are standard Land Rover high compression pistons, the largest grade are selected, to minimise clearances if the bore requires honing. Maximum allowed skirt clearance is 0.085 mm (3 to 3½ 'thou').

Valve cut-outs can be machined into the piston crown if anything other than the standard cam and valves are to be used. Standard bearings are included.

Swept volumes:
86.3 x 94.0 : 4,791 cc
86.3 x 94.51 : 4,843 cc

For later style, large main bearing blocks (4.0 & 4.6)      £2,750.00
For early style, small main bearing blocks (3.9 & 4.2)    £2,950.00

4.5 litre kit for early style, small main bearing blocks (3.9 & 4.2)

A balanced set of crank, rods, and pistons. The tuftrided and polished crankwith a stroke of 80.0 mm. The rods are the standard Land Rover type fully inspected and prepared. Pistons are modified standard Land Rover items, selected and prepared. Standard bearings included.

Swept volume : 80.0 x 94.0 : 4,441 cc                                 £1,750.00
