I have a spare bottom end which im going to rebuild, it seems in good health, no damage to tops of pistons and i turned it over via a spanner on the bottom pulley, smooth but with abit of friction which im told is ok ! Im just looking into what it will cost to rebuild, has anybody done it recently, and is it worth having the tops of the pistons shaved to lower the compression, lighting and balacing it, has anyone got any advice please.

Id like to run around 200bhp

 

get the group buy on forged rods, then get some low comp pistons

 

zippyobrien Ive seen the group buy could be interested, what do low comp pistons go for these days ?

 

They aren't cheap - low compression pistons are available in forged only - and start at around £600.

They really aren't needed until past 250hp.

 

Cheers Rick Is it ok to get the top of the piston skimmed to lower the compression ?

 

ross racing pistons are good

 

Noisy Boy how much are they?

 

£600 ish.

You can skim - but it weakens the piston. You can keep the std compression for 250hp or so.

 

If thats the case then ill just get the pistons cleaned up, what else do i need to do to the bottom end ive been told new shells, im looking to refurbish all the components in the bottom end. Prices please if people know.

Cheers

 

new oil pump, with uprated flow if you can find one, but doubt you will, new sump whilst engine is out, there a cunt to fit in the car, new oil strainer pipe and all that gubbins

 

only thing about them ross racing piston you have to order them from U.S so you be waitng a few weeks for them unless someone stocks them but they are really good pistons

 

Cheers lads i have started to strip my spare bottom end, big thanks to redrsmk5 i have pics of me and martin taking the engine apart, will post in the restoration section soon.

I have a list of parts wanted including new sump and gasket and a new oil pump, shells, piston rings !!!!

If im going to build an engine then im only doing once !!!!!!
