Title: smaller diameter bushings in VW rods... Post by: Tom G. on December 15, 2007, 10:11:24 am Hi,
this is a very special question about fitting some pistons of a foreign vehicle...in a VW engine...I want to build a screamer engine, small displacement, with high rpms and i have to, such Johannes P. said,build the engine width as short as possible... So i want to use pistons with a lower compration high..I have found some pistons from VW,opel vauxhall or BMW wich have 85,5mm-87mm but with KH of about 26-29mm...there are really nice...BUT they have all 20-21mm piston bolts...So with which material is a bushing made....And could it fitt and fuctioned with smaller bolt instead of 22mm for such high HP/L? That is only all for high rpm and low rotated masses.. ;D ;D here are some photos of my TBs(45mm Diamter,50mm intake)..i will use one Tbs per site, kadron manifolds....Megasquirt Injection...

are made from. AMPCO 45™ is'nt cheap I can tell ya >:( Cheaper and less hard bronze alloys should work too, get the hardest alloy you cn get and go for it ;D /Rolf,DK Title: Re: smaller diameter bushings in VW rods...

He bushes them from 24mm to 22mm so that you can fit typ 1 pistons(the 'B' 94 mm are lighter) to them. You can ask the if they do it for typ 1 rods. See picture |
