We started to strip out the initial 505 for the V8 this week. We made plenty of mistakes from the initial and now are proceeding into a decent attempt at a well balanced 505 with big grunt. Initially we moved the early Rover V8 back 300mm into the 505 but there were two big issues with that after we thought we had it looking good. My car is right hand drive and the v8's starter motor became perfectly situated 30mm into the power steering valve on the rack. ( Curses) The second issue is I managed to grab a fantastic example of an 85 505 GTi 2.2 auto which needs some minor dents fixed and a perfect interior and no sunroof. Rare over here. The car is one from a long standing client, recently retired to a unit so the poor old 505 got tha' boot. I drove it for a few days and she is in superb nick. So much so I thought about a tidy up recon job with a turbo 2.2 auto, combination. But I think with a little rethinking on engine position and using the very late 1997 Rover 4.6 Thor engine, which is shorter to the older units by a good 200mm, we can make a 505 with the same handling we know and expect from the 505.

Bean! How will you get the balance right? Mid mounted 5.7 Hemi??????? Now, let me see????????????????

I've been having to take a big rest this week and been mulling over a few things. The red 505 is a real nice starter and really should just get a strong 2.2 turbo with auto, but that won't give me big punch from low down. I have a hot 2.7 oddfire in the top storage with the late Volvo cross ram inlets. That with a turbo and manual, might come close but, when you look how small and neat and light the 4.6 is, not to mention how dead cool it looks, the other choices seem sort of inadequate. I want to keep balance and auto but also want off idle punch with an auto. It seems in my mind the best of both worlds without all the abs and traction control stuff.



See how compact this is!

Well the build is progressing, here are some images of the biggest problem. Steering clearance to the engine and starter.

We have worked out that the engine will go back into the car 100mm more than the Peugeot unit and then I'll make up a starter assembly to fit onto the left side of the block. That doesn't seem to have been done before so it looks like I'll use a Denso hi power Chev starter with a 9 teeth pinion and make a mounting block to fit the engine

Oh so close to moving on with the build. This clearance issue is proving difficult.

Once we decided to admit it is best to push the engine back 100mm and rework the firewall, the starter was still in the way but we found that fitting a left hand starter like a Chev, under the block, will just fit. I think the Denso unit which does not run a snout for the pinion will almost fit in behind the bell housing without having to cut for clearance.

Next week will bring new ideas.
