Twin Cam rebuild costs
Posted: Thu Jun 18, 2020 3:35 pm
I'm looking at the possibility of rebuilding a TC which has been standing for a long time. So FYI I did a couple of spreadsheets for prices. I was quite surprised that a minimal rebuild, replacing only necessary things like main bearing and con rod bolts, head bolts, all shell bearings and the rings, gaskets, thrust washers, oil pump, water pump, cam chain and so on, but without new pistons, cam sprockets or valve seats came to around £1400 including VAT. And thats using standard parts not exotic racing kit!
Having new pistons, jackshaft bearings, cam sprockets, con rods etc added another £1200.
Then there's quite a bit for outsourced machining, like rebores, block and head facing, crack testing crank, crank grinding, pressure testing head etc, etc!
Not cheap these engines, but I suspect much the same cost for any other four cylinder unit.
