How much for a 1.5 conversion??

[Richg40]

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?

[dub-disaster]

Between £1k-1.5k maybe that's just my geustimate though!!

[Richg40]

For just the bottom end? Seems a bit much?

[Henry]

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.

[dub-disaster]

Yea think henrys estimate mite be a bit more accurate than mine !!

[Richg40]

£750 about reasonable then I guess.

[hayesey]

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

[Yoof]

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

[PeteG40]

depends on whether cranks been balanced too - and if relief work/boring been done and by who

[Richg40]

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.

[hayesey]

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

[Richg40]

Nah man don't know any Gregg.

[hayesey]

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

[Richg40]

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