Post subject:  Building a motor
Hi

Been reading vizard book so I can learn stuff

When deciding to build a motor how do you work out what
you need

do you go well I want 75hp so lets find the parts from that?

or do you go I want a RE13 cam and go from there?


sorry for stupid question

If it were me I'd work out what I have to spend and build it according to maximum reliability and quality of parts and workmanship for the money, as opposed to building by horsepower.

I'd rather have an engine with a little less power if it's more likely to run trouble free for longer.

Work out what you want from an engine. Then research what will give you that for the highest relaibilty/cheapest cost.

And dont forget a gearbox to up the cost. That opens up another can of worms for options and possible issues.

So itd help if you told us what you wanted.

How much of the build are you prepared to do yourself? Do you already have a motor and box or do you still have to purchase one and that is part of the $3k?

Surely budget has some influence on it? If you had no budget then you'd have an injected turbo 1.4 litre 6 speed A series engine! :D

I have (or will when it arrives) a 1275
just need a box I have a spare remote and my car takes rod
and I don’t want to use my current rod change box as its really dodge

I am prepared to do as much work as I am capable of doing

I have 3 grand for the parts and box

I will need reliabilty as well

Decide on what you want to spend and work from that. I am currently building 2 1100 engines for customers, a 1275 race motor and a 950 morris minor engine, they range in cost from around $2000 to $8000 just in parts alone! An example for cost purposes would be one of the 1100's I am currently building. I have purchased so far:

Modified "race" head, big valves, new springs etc
New 45 DCOE Weber & inlet manifold
Lightened steel flywheel & backplate
"Race" clutch plate & diaphram
"Race" wide lobe camshaft
High comp pistons
Roller Rockers
Vernier timing gear kit
S/C 4 snc gear set
S/H Mini K gearbox

All this has cost me just under $6000 and I am yet to pay for any engine bearings & gaskets, all the gearbox bearings, Balancing & machine work, extractors & exhaust and then the added cost of my labour.

You wont need to purchase some of the extravagent items for a road car but be prepared to spend at least $3000 just in parts to build a quick motor.
Cheers
David.

oh well there goes that idea of having a mean street mini

I will have to save a bit more and maybe than go all out
It might be best saving the extra amount than having to
re do it when you get more money

We dont mean to crush your dreams, but its just what things cost.
Is the 1275 engine you got complete? Or is it missing things like carbs, the dizzy, the coil, flywheel etc?

While you there, do you have disc brakes and all the bits and bobs that they entail?

Post subject: 
nah I should have understand more

I think so but I am going to put my 1.5inch carby on it
and transfer my external stuff on my current engine to the new one

disc brakes ...um ..well ...you ..see

I am working on that :lol: might take a bit longer

I am open to advice and ideas as such

Have you thought about a rover front cut?
If you could get a carb 1275 halfcut youd be well on the way. You could sell off the bits you dont need, and you also get a gearbox and the driveshafts and disc brakes at the same time.
