Oakmaster Posted May 11, 2010 Share Posted May 11, 2010 I wonder if you might be able to help me. With an engine number query? While filling in the insurance forms for a recently acquired Landrover I had to state the engine number, The number stamped on the block is 28G00271A compression ration is 8.13 : 1 This doesn't seem to fit into any of the series of numbers available on the commonly featured websites? Anybody know where it came from? The engine was transplanted into a 1989 Landrover 110 pick-up, 3 owners back and was thought to have come from a Ranger Rover Many thanks Quote Link to comment Share on other sites More sharing options...
western Posted May 11, 2010 Share Posted May 11, 2010 Can't find a 28G V8, but have found a 28D00001 Carb non-detoxed V8 8.13:1 CR with manual gearbox fitted to RR 1986 to 1991 model year vehicles. Discovery 1 had a Carb V8 8.13:1CR but with a 27G prefix. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 11, 2010 Share Posted May 11, 2010 Have a look on the cylinder head casting dates, this should give you a way to narrow it down a bit Quote Link to comment Share on other sites More sharing options...

My transplanted V8 90 Land Rover came with a letter from Land Rover Traceability department confirming it's original manufacture date.

It has always been rumoured, but never actually confirmed with documentary evidence, that the 28G engines were the last to be supplied to the MOD in the 3.5L capacity. These were in late model 127 ambulances. Quote Link to comment Share on other sites More sharing options...

I wonder what they did to reduce the power? (and how do I reverse it?) Quote Link to comment Share on other sites More sharing options...
Aragorn Posted May 13, 2010 Share Posted May 13, 2010 Probably restrictors in the inlet manifold, and quite possibly an unlumpy cam and low compression ratio. If its done any sort of mileage the cams probably due replacement anyway, so you can chuck a decent 3.9 efi cam in there, and ditching the carbs for EFI should see the rest of the power return Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted May 13, 2010 Share Posted May 13, 2010 Poss a 8.13 : 1 Compression ratio, is the ratio not stamped next to engine number at the joint pf the head to the block ? 8.13 used to allow poor fuel to be used, compression is in the pistons, so often not costs effecient to sort Nige Quote Link to comment Share on other sites More sharing options...
Oakmaster Posted May 13, 2010 Author Share Posted May 13, 2010 I can confirm it is a 8.13 : 1 Compression ratio, maybe thats it? did they still use restrictors by then? My stage one V8 109 had them (but not for long!) Quote Link to comment Share on other sites More sharing options...
Aragorn Posted May 13, 2010 Share Posted May 13, 2010 My old disco had a 27G carb engine, and it had restrictors fitted. Quote Link to comment Share on other sites More sharing options...
