Hi all
Im restoring a US 1976 2.0 with a 1973 2.0 engine (not sure how that happened but hey). Im in the UK and these are as rare as hens teeth. Ive decided to retrofit a standard FI system (currently gathering the relevant bits). My engine builder has suggested a Web cam - WEB #73 262/262 duration 0.426 lift which I believe is correct. Any ideas on what pistons I should use? The 73 engine has bus pistons which are in good shape but if Im going to the expense of rebuilding then I feel I should put something better back in. Im not looking to build a hot rod just a nice reliable fun motor. My engine chap is suggesting Keith and Black pistons (96mm). Would that work or are there better options? thanks Andrew |

While the nice folks at Web Cam mean well, they've been saying for decades that this cam works with D-jet, and it does, if you don't mind low vacuum and poor performance (including idle) under about 2000 RPM. I suggest you look elsewhere for your camshaft. The stock grind is best for the money, and it is said that Jake Raby has a camshaft that works well. Remember to buy lifters from the same source as you buy your camshaft. If I were you, I would purchase a set of factory pistons and cylinders. They're readily available, and the quality is high, unlike most of the less expensive aftermarket brands (which are made in China).

The engine chap was keen to change the cam to make an improvement from stock. Dont ask me what it was meant to do (Im not an engine guy as you can probably tell) something about making it breathe better. Do I need to go to Porsche for the piston kits? thanks Andrew |
