robertspark Posted October 27, 2014 Share Posted October 27, 2014 I can't seem to copy and paste the link (iphone/mobile web page) but there is a v8 automatic conversion listed in the technical archive section and there is also google searching for something like defender v8 automatic conversion as it's a path well trodden Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted November 12, 2014 Share Posted November 12, 2014 If you ask "should I buy this" we would ask you to say what you are trying to achieve. I personally do not like the company "partsrange" (also known as RPI engineering) and would recommend Real Steel or V8Tuner.co.uk Quote Link to comment Share on other sites More sharing options...
Alex1933 Posted November 13, 2014 Author Share Posted November 13, 2014 Thank you !!! I want to increase the power of the engine and do not know how! Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 13, 2014 Share Posted November 13, 2014 Defender 3.5 V8 are de-tuned (for bad fuel / hard work) so there are simple things you can do: 1. The carbs may have restrictor plates in them, remove them. 2. Check the compression ratio (stamped on the engine block), if it is low compression (<9.35:1) that is a bad start. 3. Converting to fuel injection (Lucas 14CU / 14CUX from Range Rover or use Megasquirt) will gain some power & driveability without mechanical changes. Depending on prices in your country, it is easier to buy an engine from a Range Rover that has EFI, if it is bigger (3.9, 4.0, 4.2 or 4.6) that is a good gain as well. Buying "performance" parts for an old 3.5 is an expensive way to get more power. Quote Link to comment Share on other sites More sharing options...

Team Idris Posted November 14, 2014 Share Posted November 14, 2014 Maybe they are not restrictor plates? If they are star/spikey they are there to mix the air and fuel. Restrictor plates are a plate with a smaller hole fitted between carb and manifold casting. Quote Link to comment Share on other sites More sharing options...

robertspark Posted December 17, 2014 Share Posted December 17, 2014 I'm not sure about the restrictor plates. But the common thing to do was to change the camshaft I think for a 3.9L camshaft. The other thing to try to do is to change the exhaust system for something which is free flowing (removes one of the scilencer boxes), that will bring about small / modest gains. Changing the compression ratio will require new pistons + an engine rebuild In standard tune they are suppose to provide about 135 hp, at best I think the SD1 rover with a high compression 3.5L engine got about 190hp (but not on carbs), but it was also further up the rev range, which is not so beneficial for a landrover, given low speed torque is normally affected. The normal "cheap" thing to do these days is find a 3.9L engine and install that as they go for relatively little money in the UK now given the number of discovery's and range rovers that have been broken for spares. Then it's fitting a 4.6L that will bring the next most cost effective power gains up to about 240hp, after that it tends to be expensive for the rover v8, but with a greater torque improvement percentage. The main thing to start off with is to service the vehicle as it is and make sure that its in good condition with the carbs tuned and balanced, and the timing is correct, the timing chain is not worn, there is no missfiring or hydraulic lifter rattles / sticking, and it has new plugs, etc Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted December 18, 2014 Share Posted December 18, 2014 Restrictors are the 4-hole plates in the inlet manifold , shown in this thread here: http://www.stage1v8.org.uk/phpBB3/viewtopic.php?f=6&t=1499 Pull them out and ~45BHP more. I don't know what age your vehicle is, but after a certain date they stopped fitting them anyways. Quote Link to comment Share on other sites More sharing options...
Chicken Drumstick Posted December 18, 2014 Share Posted December 18, 2014 Factory 3.5's (Ninety/One Ten) use Strombergs not SU's. They are all low CR as far as I know, unless something was different for export markets. If you have a 3.5 on SU's, then it isn't factory stock in a 90.
