How much for a 1.5 conversion??
« on: August 09, 2010, 09:47:49 pm »
Lets say you knew someone selling a 1.5 bottom end, G40 block, brand new 1W crank, brand new custom accralite pisons with new main and big end bearings.....

how much would be reasonable to pay?

For just the bottom end? Seems a bit much?

I was under the impression that brand new cranks are £250-300, pistons are £500-550 brand new, g40 block is worth something like £50 and however much the bearings are worth minus a percentage for second hand value and that gives you a rough price.

£750 would be a bloody bargain, don't forget at least £100 block machining, £100 set of bearings...

Also depends which block has been used, and who's done the work.

It's a G40 block, built by a BMW senior tech and the boring was done by the machine shop they use to a very high standard.

offer £750 and see what happens.  Is it a guy called Gregg who is selling it?

oh OK.  It's just I know of a lad who used to be into g40s who (I think) is a senior bmw tech, just wondered if it was the same guy.  No idea if he ever built a 1.5 bottom end though.

new oil pump with it as that'd be another 100plus for that. it would cost you over a grand to do

No oil pump, but it shouldn't be a problem to get one at trade genuine i guess.
