If you possess a Rover P5B V8 product like me, you possibly enjoy the motor vehicle but could do with a lot more power. The authentic engine in the P5B is of the 3500cc wide variety. The good thing when it was initial launched was it experienced a increased compression ratio than some of the later on engines, but mainly because the heads experienced lesser inlet and outlet valves it still limited the power some what. The other disadvantage was the dilemma of leaded gas not currently being out there so you have to hold including guide additives to the gas which quite a few a P5 owner appreciates is a little bit of a soreness as you are constantly down the gas station with these types of a major motor.
My 1st trick was to switch the heads with heads from the Rover SD1 which with the larger valves and unleaded valve stems saved me the task of placing in the fuel additive just about every time but I didn’t truly detect substantially extra ability. The Rover P5B is a incredibly major auto anyway and I suppose your not intended to travel it speedy but I was hoping for a small improve in efficiency. I then additional a Weber Carburetter and altered the ignition to a Lumenition digital ignition technique to get rid of the old details process. This designed a bit of a variation but the overall performance was not what I would get in touch with startling.
Then I made a decision to dig deep into my pockets, rob the piggy financial institution and opt for fitting the 4.6 ltr engine from the later Variety rovers. Now this motor is definitely the same unique block as the 3.5 ltr from the Rover P5, so truly it is just about a straight swap. If you are maintaining the primary distributor from the P5 then you have to maintain the very same entrance include from the engine mainly because the oil pump teeth are distinct for every model. Aside from that every little thing goes in nicely. The motor mounts line up and all the exhaust manifolds go back again jointly just as the outdated one particular. If you hoping to retain your Rover hunting primary, you can even use the authentic rocker addresses so even the coverage gentleman could not inform the distinction. Until eventually he drove it of class.
How does it generate? Very well, amongst the two engines is like among day and night. You will be grinning from ear to ear for days afterwards. So if you have a couple spare bob and need to have your Rover P5 to choose up its heels and go. Your only solution has to be the 4.6Ltr V8.
