the buy stuff from abroad, get an engine builder to do the work route of modding a car is all well and good if you can do the majority of the work yourself. i.e removing the engine, stripping the engine, then bolting it all back up when the builds done but if you cant what do you end up with worst case scenario ?
so and so takes engine out, someone else builds it, someone else puts it back but the so and so that took it out has lost bolts, rounded heads off blah, blah, so the someone else that puts it back in doesn't worry about it, everything's ready to go and........................the car wont start and nothing that's being done to it is going to get it going.
who do you point the finger at then ?
the bloke who puts the engine back in will say he's only put the engine in, the engine builder will say I've only built the engine, the bloke that took the engine out will say i only took an engine out.
you've spent a load of money and the car doesn't work and you're fooked...where do you go then ?
to many cooks spoil the broth and all that
its all well and good buying loads of parts yourself but you could end up in the shit anyways.
people that cant, don't want to or don't know anyone that can do the work, would be best of with one company/person doing the f@cking lot and be done with it, if you have to buy parts through them so be it.
