BUMPING this thread:

I'm planning on a 4JG2T conversion to my 1989 110 V8 CSW.

The 4JG2T weighs 350kgs compared to the 175kgs-odd of Rover V8.

I also have a 2-inch lift with coil springs of unknown origin (could be Britpart, could be OME, I have no idea).

The 300TDi weighs around 205kgs.

So do I use D90 HD rear springs, or fork out for something like the OEM heavy duty 2-inch lift springs?

Are you sure about the weight of the 4JG2? The 4BD1T is 350kg and the 4J engines are a lot more compact.

No, I'm NOT sure.

That's an estimate. Should I revise it down to the 250kg area?

I can't find any Google reference to the weight.

Non-turbo version, but some info here that has it at 244kg.

Thanks Steve! A turbo will add another 10kgs-odd, so 255 kgs will be in the ball park.

Will 180 lb/inch springs still do the job, do you reckon, or should I go for 200lb/inch?

Spring rates depend on the weight being carried. I'm holding up ~1150kg per axle with 180lb/in springs and I'm very happy with the ride.

Ride height is another concern.
