I am puzzled by the reference to the "narrower V" . As far as I can see, this engine is a 90 degree V8, and thus perfectly standard in concept. The only narrower v V8 which I can think of was the one Jaguar tried out in the 1970s, being two-thirds of the 5343cc V12 and thus a 60 degree Vee. It proved to have terrible vibration periods and a very peculiar sound, and so was rejected and never put into production

Modified at RoverP5club dot org dot uk When I can get a few better pictures I'll send you some pics and details. I just hope the traditionalists don't issue a Fatwa :-) As I said the car will be totally standard outside and inside, it's more RestoMod than Hot Rod.

At the end of the day I bought a compact packaging kit anyway. It certainly wouldn't have fitted if the ancillaries were hanging out sideways any more than they currently do. There's certainly no option to add anything else without having to modify metalwork.

I have already said my piece!!!
If you feel you need to make comments about posts in this section please realise this section is for the guys who wish to modify their cars! you may not agree with the content of the posts! if you feel that way "DON'T READ THE POSTS" or make comments if not constructive or relevant to the post, as I have said this is their section!!!!
If you feel you have to make comments there are lots of sections you can make your points in apart from this one! some of the guys on here have a lot of talent and very good engineers so we need to respect that please!!
If there are posts that are intended to aggravate (in my or my fellow mods opinion) in "ANY section" of the forum it will be deleted and a warning given.

Thanks for that direct comment John. Individuals posting to the Modified section should feel free to post and converse about their cars without derision or sanctimonious moralising about the Rover heritage or how a repair/renovation should be carried out. Unfortunately much useful/technically interesting information is going by way of PM rather than being illustrated on the forum for all to see who have an interest in this section, due to the narrow mindedness of a few.

And so is way of the world and is accepted with people who modify their vehicles. It doesn't really need to be pointed out in this section. John has done the right thing to separate it out and lets hope its an end to it here.
All modifiers feel free to show yourselves!

cool sounding project, I too have undertaken similar modifications on my p5b. I.e ford 9inch with truetrac lsd mounted with a tri four bar set up, rack and pinion steering, new front suspension disks and coilovers all round...I havent quite got round to my engine swap yet, need to do some saving first. Good luck with your project, hopefully see it on the road soon...Gonna be a beast ! Hi, Have you any pictures of the rear set up (Four Bar) Cheers, Kev.

Pleased to see you posting to the modified section and to also see the progress to your car. The engineering and quality of work looks first class Bismire. Looking forward to see what happens next and to any mods you add to improve the chassis and suspension. PS. I believe we're done with negative comments in this section by aggrieved traditionalists as the moderators have clearly drawn a line. So hopefully now individuals doing a range of mods from very mild to the extreme, will feel comfortable enough to post their work and discuss it!

I am also modding my P5 but I am using a modified Ford 302 with a 4r70w auto tranny and 3.73 ford rear end building for nice long drives and great gas milage . I am about a month in my rebuild , just yanked out the old seized up straight 6 and tranny , but summer temps around here gets up to 106 degrees , so progress is slow . Test fitted the mockup engine and trans today ,seems to fit ok with simple engine mount brackets using 94 range rover engine mounts , as for the steering ,going from gearbox type to rack and pinion using a rack from a Bmw 3 series , had to change the oil pan and get one from a 86 mustang with the double sump so that the rack and pinion will fit higher up in the subframe .As for for the rear end ,thinking about using a ford ranger since its closer in length about 1 1/2 inches shorter and refit the spring mounting bracket . Need to change up the front end suspension any Ideas my fellow modders ? will post pics soon having fun in the USA

Welcome 3ne2nr, it sounds like you have an interesting project underway. I'm pleased that you've posted some details about your project here. Why not consider starting a fresh topic about your vehicle? This ensures Bismire's project P5C retains its integrity, making it easier to follow his progress. Ensure you post your topic in the ' Modified' section, as this will keep the traditionalists happy and your audience will be those other P5 enthusiasts who have an interest in modifications and innovative engineering from mild to wild. If you require some help to set up a topic, I'll be pleased to assist you. As an aside, engineering solutions for the steering such as fitting the BMW power rack is something that would interest me as the Factory PS is directionally vague at speed, although fine for parking and quietly tootling down country lanes/suburban streets.

Read more: roverp5.proboards.com/thread/9150/p5c?page=2#ixzz3id0YaOsNChanging caster angles will help sort this straight line stability problem out. I can start a new thread on how to do this mod if anyone is interested but you can only manage around 3 degrease depending on the front wheel backspace and diameter. Three degrees is enough to keep the car going in a straight line at speed. Changing the engine for a larger v8 will probably make the steer box intrusive and a rack will help with more space for manifolds Well worth doing if you intend keeping the original steering box and front suspension. Please post up on how to change to a BMW rack.

Hi Enigmas, sorry for the confusion. Just to be clear my SILVER BIRCH ROVER P5B has nothing to do with P5C's project.

Hi All, So, it's been a while but progress has been made. I now have a 4 link rear end with Watts linkage to locate a custom made Ford 9" axle with LSD and disc brakes with Trigger Wheels for Traction/Launch control. Now it's all coming out again to allow clean up and paint to the underside of the rear before permanent fitting in location. Cheers, SF

In addition I have a complete IFS using unequal length wishbones and coil-overs. The hubs also have the front end Trigger Wheels to complete the 4 wheel speed sensing system. This is going to be mounted on a custom made (much stronger) subframe. Steering is a rebuilt Cortina quick rack which will be assisted using Electric Power Assisted Steering. Cheers, SF

And in case you forgot why I need that front and rear set up its because I got a bit carried away with the engine ...... LS derived LQ4 with all steel long stroke bottom end (6600cc), Fuel Injection, Distributorless Ignition, ported / polished LS heads ..... Heavily uprated TH400 with Gear Vendors overdrive working on 2nd and 3rd giving what amounts to a 5sp transmission. Cheers, SF

Wow! This really has turned into a big dollar build. The quality of the components and the fabrication work is second to none. Looking forward to seeing the car in its final and completed state.

Hi, It will be hard to tell just by looking at it as apart from a non standard colour (still silver over blue, just a different silver and blue) it will look completely standard outside and inside, the wider Minilites instead of Rostyles and slightly lower stance will be an indicator, but apart from that I just want to look like a nicely restored P5 Coupe. That said I'm tempted to modify the OEM wheels to a larger width rim (as in another post), an excellent idea I must say which will also retain a more standard look :-) Cheers, SF

HI, Good to see your project is coming along nicely. I have a Wisbech front end with Cortina steering rack on my car, which to be honest is a pain in the arse (i'm talking about the steering rack here) its 4 turns lock to lock and far to heavy to turn in town...if you are going for the electric assist i would be tempted to try a rack with 2.8 / 3 turns lock to lock.
just a thought as i will be changing my rack as soon as.

Sorry, i didnt see you had a quick rack on your Cortina rack...whats the ratio or turns on that one ? thanks.
Also on the rear of your car, it looks like you have mounted your shocks to the chassis rail? which is what i did...I'm running 11” open dampers which is 8” closed, metal to metal (total stroke 3”) which is nowhere near enough. I was originally running the ProTech shocks with a spring rate of 350 which kept bottoming out. I then went to 450, 550, 625, then 750 which is where the shocks no longer bottomed out. as you can imagine the ride was harsh. I then bought a set of TraxSpax double adjustable shocks, which have been correctly valved for the weight of the car, see if i could extract a little more from my rear set up...Nope, well a bit but nowhere near enough. I would say 5" total stroke is minimum on the rear of the Rover.
I will be changing the rear setup of my car...Again ;[
I hope this helps,
Jamie

Jamie (Bismire) I'd understand if you were doing some of the work yourself(?), but funding all the seemingly endless changes to spring rates, shockers, rear end layouts, various steering racks, etc, etc, and finding issues/problems to solutions, has got to be either horrendously expensive or you've either second mortgaged the house, won a lottery or inherited a huge sum from a generous benefactor.
I get modified cars when built to a plan either long or short term and I can see a lot of quality in the work carried out, but marrying components no matter how nicely made that don't or won't work in unison is a road to an expensive disaster.
As an aside, If you're still running the Rover front suspension, how did you correct the steering for the rack and pinion system you mentioned to provide correct ackermann?
