Honestly, just learn it like anything else. Understand the basic components of an internal combustion engine (block, crankshaft, rods, pistons, camshafts, cylinder heads, valves, intake and exhaust manifolds), the 4 cycles the engine goes through (intake, compression, power, and exhaust), how fuel delivery and ignition systems work. And then there are tons of resources on tuning and you can get the software for a laptop.

Then there is the building of the engine and understanding clearances for specific applications and RPM's, value train harmonics when thing start getting to crazy high revs like 9500.

Still very learnable but outside the scope of standard engine rebuilt stuff.

It isn't that simple. I've been learning to work on my own car over the last few years. I'm not even doing anything crazy just fixing up an older vehicle and modernising some parts of it (mainly interior).

I had to fix the wiper system. The wiper system you would think it wouldn't matter much whether the parts are aftermarket or not. I was very wrong, parts that even look almost identical may not work properly, due to differences in tolerances.

There is also different revisions of particular parts and it will become obsolete. You can lose an afternoon on the internet just doing that.

Then there is the tools. I've spent about a small fortune on tools. I have 3 torque wrenches, 3 sets of sockets, 3 sets of spanners and loads of weird specialist tools like special pliers. There are many jobs I can't do myself because they needs specialist knowledge to do properly e.g. gearboxes.

You have to be prepared to spend potentially years on it and huge amount of money, even on relatively simple projects.

There is a reason that a lot of guys get into old 4x4 pickups and do those up, because they are a known quantity and parts are readily available.

As someone building a particularly stupid car in a genre almost but not entirely unlike the OP (a turbo LS1-swapped Rover P5), I am not totally making stuff up when I say that this:

> You have to be prepared to spend potentially years on it and huge amount of money, even on relatively simple projects.

is not at all mutually exclusive to this:

> Honestly, just learn it like anything else.

I didn't really know what I was doing when I started my project. I had an idea and the desire to make it happen. I barely knew how to use a MIG to do the fab work, so I got good (enough) at it. I knew nothing about LS engines, so I learned enough about them at each point I needed to know something about them. I only have a vague idea of how I'm going to do the next phase of it; I know that I can figure it out with enough thinking and by making all the mistakes I need to make. I don't know how to TIG, and it'll be really useful if I do, so I am learning how to TIG.

Start somewhere, and the more you do, the more you can do.

I have no idea why people do this stuff to a nice car like a Rover P5. It isn't my car though.

> Start somewhere, and the more you do, the more you can do.

Obviously. But I had to do a lot of stuff that I wasn't prepared to do far quicker because the previous person who doing this took short cuts. I almost had the dash catch fire because someone did a bodge job on electricals instead of paying £15 for the correct part (a plastic plug).

The point I was making is that you are making it sound far simpler than it actually is. There been a good few weekends that have been sunny and I have honestly felt like I was wasting my time and couldn't face working on it.

I had to fit a new turbo and it took me about 3-4 weeks. Not because it was difficult (actually it one of the easier and nicer jobs IMO), it was sourcing parts around the turbo such as gaskets, copper washer kits and other dumb stuff like that.

There was constant trips to tool shops because I was always missing like a tool, trying to find a fitting/gromit in Halfords (they never have it) or a parts supplier 40 miles away in the sticks. It all adds up in both time and cost.

Now I know roughly who the order from, what I should order from etc. But that is going to be different for almost different manufacturer and worse if the stuff is more niche/custom.

The amount of the projects that get given up, suggest it not that easy.

(I don't know why your comment got flagged. I vouched for it; whatever we might argue about here, I don't think you're out of line in any way.)

I actually feel everything you have said apart from this P5 being "nice" (it was fucked). Like turbo delays - I had that on my other project, and going from "I need a new turbo" to "I have a new turbo and things adjacent to the turbo" took damn near a year by itself. I know how this goes!

So I hope I did not appear to say that it's EASY. I've put in enough hours to know that it's not, and if it was everyone would be doing it anyway. It does in fact take a lot of time, and willingness to learn, and plain old determination, and money. I will say it's something that IS possible, and that I still agree with this:

> Honestly, just learn it like anything else.

But...I suppose we'll know that for sure once I have an actual working car, right? :)

>Honestly, just learn it like anything else.

If you're starting from 0 that's probably a decade long commitment before you're able to start to execute a project like this. There's a youtube series 'project binky' where a pair of professional car tuners rebuild a mini cooper and stuff a Celica engine in it. They already have all the skills, own a shop and all the tools and it still took them years.

[spike021]

similarly, there's a youtube channel called Mighty Car Mods that does builds also and even the ones they "rush" can take months and thousands of work hours from people from multiple disciplines (body repair, paint, electrical work, tuning, etc.). Not cheap at all.

A decade would be very quick. The amount of specialist knowledge that went into every part of this project is crazy.. After a decade's worth of projects I doubt I'd be confident to tackle the steering and suspension design on something like this, let alone all the aero.

I've been working on cars for 20yr, I weld, I have done CAD/CAM/CAE stuff, rebuilt and modified engines, done custom suspension work... there are so many aspects of a project like this that are just completely unknown to me, like I wouldn't even know where to start. Many aspects of this build are not things you can really learn or research on your own.
