hi newbie here just wondering if anyone knew him and the spec on this engine as would like to build one of these engine with a little help from the person in general also any full on pics thanks all
As that spec but with uprated valve springs ti caps and single piece stainless valves. And the throttle bodies are 52mm now. Pics Uprated valves are a must Edited by: Mad 20v
thank you all for replying and thank you mad20v for building a great car sick of turbo this and turbo nothing like a n/a engine kicking ass mad20v any chance of the contact details of the guy who built the engine for ya was really thinking if this doesn't go to plan a fully worked 2ltr 16v on throttle bodies
oh yes.. Thats why I made it my mission to find something better. Seems pointless building a top spec motor only to retain the weak std valves in it. One piece Forged stainless valves EV80, black nitrided with optional inconel exhaust valves (for turbo 20VT)
Dont say anything, im waiting for it to blow apart Wish i knew that before one snaped. Edited by: Mad 20v
pure filth ! graham was how i found this site too the 2 piece standard valves are a bit of a bugbear. vauxhall twincam engines are the same. in our case the head and stem are 2 different types of metal. this is purely because theres not 1 single type of stainless steel that is both durable for valve stem work and to widthstand the hammering and extreme heat and cold in the combustion chamber. one piece valves tend to err on the steel most suitable for the combustion chamber duties, and you have to accept that the stem will wear quicker than in a road engine.
lol, yeah I've heard alot of people say that after theirs has gone bang too. As for John Reed racing. I've heard he can charge 6k just for labour on some of his engines! Though his work is fully warranted to back. But at the same time he can get 199.5bhp out of a 1.4 16v corsa engine revving to 9k +
remembering manufacturers are building to a price not neccessarily a spec which can cope with more power or revs
He built a 2L vauxhall not so long ago for a m8 that races rally X put out 298bhp on the test bed and reved to 10500rpm Edited by: Mad 20v
heard good things about him, but you pay for the quality JE built 240bhp xe in rob halls mini has been going strong for years and that gets some stick
mad 20v engine spec does anyone have the spec available of graham vanstone's mk1 20v NA engine? been trying to find out a bit of info for someone but can't find it. i know he sold it onto someone else on here but can't remember who. ta much!
the blue one? seen here with a few problems ouch the geezer that now owns the blue frequents the forum now and again.
Missed your PM pol - I'm sure Graham will put up some of the spec. A full race motor by all accounts.
