Well I kind of got into this by accident, sitting in an MOT waiting area browsing the magazines and an advert caught my eye for kit car parts, not that this a usual area of interest for me so cant really say why, but I did some googling and one thing led to another and the next thing I know is I’ve got all excited about building a kit car.

Now it’s not really a kit car in the sense of buying all the bits and bolting them together but more of a case of literally building as much as possible myself from raw materials and utilising parts from other cars. I’ve bought both MIG and TIG welders second hand with a combined cost of £800 + about £200 on consumables, ironically for around that money I could have bought a fully welded chassis complete but that’s not the point, a large part of the drive for me is to learn the skills and fabricate and finish as many parts as I can myself, an undertaking which I am not taking lightly.

Over the past 12 – 18 months I’ve been gathering tools and a few bits and pieces, creating a decent man cave to work in and although its not big enough to do the chassis in it’s a nice enough area to work on all the small parts.

Apart from all the usual spanners, screwdrivers and socket sets etc etc that are obviously going to be needed I either already had or collected quite a few bits, some of the main ones are:

• Compressor
• Murex 245A Mig Welder
• PortaMig 220A Tig Welder
• Angle grinder (could do with 2 or 3 to save switching discs)
• Sand Blast Cabinet
• Pillar Drill
• Battery Drill x 2
• 110v Mains Drill
• Various Air Tools
• Metal Chop Saw
• Old Cooker

Lots of confusion to start with in terms of choice of running gear, in the end it was decided by opportunity, a set of Granada Scorpio Cosworth running gear including front uprights, rear hubs, disc brakes all round, koala diff and driveshaft’s came up on ebay and I bagged the lot for £100 so that decided that. The guy also had the wheels off the car with legal tyres which I also had for an extra £50. I also kept the BMW diff, shafts and prop as an option.


Choice of engine, this got me for a while but I finally chose the BMW 3.0 V8, Why? Cos it’s a V8 :) and it looks good. Simples!

I chose to buy a complete car even though I only wanted the engine, this was so I could drive it round a bit, make sure everything was ok and be 100% sure I wasn’t missing any bits. Also this way I could sell all the other bits to recoup some money, in the end the car including transport and other fees owed me about £850 and I managed to get about £2000 back over 6 months of breaking it and still have the engine as well. The extra money was used to pay for the extra tools and stuff above.

As I knew the engine was going to be a tight fit I made up a wooden frame to the same dimensions as the book chassis, the first trial fit proved that the odd shaped sump would definitely be in the way, as would the alternator. Unfortunately the sump also contains the oil pump which is chain driven below the crankshaft so modifying the sump is not going to be an option so the plan is to go with a dry sump system, this will mean another expensive outlay but at least I can put it off till much later in the build. Also the alternator is going to be in the way so will have find an alternative arrangement for that as well.

Hi bruce

Good to meet you the other day,had a few thoughts about your build so posting here ,instead of making the chassis and trying to get the v8 to fit what about making the build table with a hole in it ( I can flip that sheet re etch lines and cut out hole) mount the engine and gearbox to the table and build the chassis around it you could set a jig for the front wish bone brackets so they are in the same place,the rest can then adjusted to suit up till the rear section that will be standard book.

Anybody think this is a good idear :?: or am I talking sh**e

That is the way I would do it but you have to be careful that you can still get the engine out again after you've made the chassis. I've also suggested ways on how to make fitting standard size body parts work with the size of the engine as well.

Forgot about my own build thread, should really try and add something to it! Oops

Rich, is this your polite way of saying that I'm such a short arse I need a complete custom chassis making just so I can reach the pedals :lol: :lol: :lol: For everyone else's amusement I sat in rich's car and my feet must have been at least 3" to 4" away from the pedals :oops:

Seriously though Rich that does sound like a bloody good idea, I've got 12No 2.4m lengths of old racking bars that I was going to use to build a support frame out of for the table so they will definitely come in useful and that can also go on to the next builder :D :D


Phil, my head's going round in circles at the minute, which bodywork post do you mean?

If your 3-4" from the pedals and there is no seat it means you have room for the seat to adjusted, you run in to problems when your back is against the steel work and can still reach the pedals.
The body work post I'm talking about is the one where I told you to lift the top chassis rail,raise the seat base, push the bulk head back and run the steering shaft over the top. This means you would not have to chop the sump and could still use standard nose,bonnet and scuttle with out having to custom make every thing.

Phil, I might have mislead you a bit, Rich did have a seat in, but he also had some adjustment available for it to go forwards, he's a little taller than me :lol:

I do recall that bodywork post :D As much as I'd like to be wrong the original oil pump sticks down a good 5" below the lower block line and while I agree I could raise the sides to accommodate it leaving only custom sides to be made I think overall it would be a better solution to go dry sump enabling the lump to sit lower down and traditional chassis dimensions kept.

Another aspect of this is that a certain supplier is touting opinions regarding possible all in one bodywork solutions on another well known forum :lol: I'm a fair while from needing bodywork but in truth I am hoping that by the time I get to that stage there may be more options available than there are now, so anything I can do to keep the external chassis dimensions to book spec may be more important later than they are now :?

I think your going the right way with this Bruce. Dry sump and dump the weight as low as possible. I think you can stretch a roadster but you cant thicken it. As soon as that extra bit goes on the height it sort of goes out of proportion. If need be a bump in the bonnet is better than spoilng the lines. This is of course all in my humble worthless opinion :lol:
