scottybo Posted February 13, 2014 Author Share Posted February 13, 2014 Vag 'agu' engine pistons are 81mm bore compared to the zetecs ( i think) 80.6mm. They can also be had for around 60 quid for a set of 4. Used of course. Link to comment Share on other sites More sharing options...
Stu Posted February 13, 2014 Share Posted February 13, 2014 The silver-top small end is 13/16th of an inch, or 20.63mm. The Vauxhall pistons are 21mm, which allows for a slight reaming and then interference fit. I don't know any of the VAG piston geometries. You're looking for a piston around 80.7 - 81.5mm diamter, 21mm pin, ~30mm compression height. I think some of the early Renault Clio Williams 16v/Williams may be somewhere close, too.

scottybo Posted February 13, 2014 Author Share Posted February 13, 2014 vag pistons are 81mm bore, with a 20mm pin, so no good? Link to comment Share on other sites More sharing options...
PeeWee Posted February 13, 2014 Share Posted February 13, 2014 I know nothing about engines but would suggest: 1: Make an honest shopping list of how much this will cost before buying any more random items2: Weigh up make a list of time, disappointment, headache, effort and heartache3: Drive then price up cheap impreza's, enjoy the fun and decide if you might get more pleasure from that4: Remember how long the Escort/Fiesta shell your going to ram this engine into will actually last now?5: have a wank to release frustration then start from 1: again to see if your answers vary.

Craig855S Posted February 13, 2014 Share Posted February 13, 2014 Im gonna echothe sentiments of others when I say you can get much more grin factor from a car that you buy that had a decent engine from the getgo, plenty of fast cars can be bought for pittence these days (Im a volvo man myself so if i wanted cheap speed id get a T5 tomorrow, as it is I have a NA petrol volvo with 170BHP) Link to comment Share on other sites More sharing options...
bongo Posted February 13, 2014 Share Posted February 13, 2014 my opinion..... anyone can buy a turbo car and drive it.... but to me there's something about having something thats not normal, ie a car with a turbo engine that it didn't come with,and having something thats unique.

Is sticking a nippy engine in an old Fiesta or Escort unique these days? I'd say a 20-25 year old mint OE car was more unusual than a bodged go faster one.

scottybo Posted February 14, 2014 Author Share Posted February 14, 2014 always with the word bodged! just because its been changed doesnt mean its been bodged lol Link to comment Share on other sites More sharing options...
Craig855S Posted February 14, 2014 Share Posted February 14, 2014 Anything that was built on a shoestring is bodged. So unless you're going to do it to a standard an OE engine would be built then that's that, decomp plates and whatnot are bodges Link to comment Share on other sites More sharing options...

Dubs Posted February 15, 2014 Share Posted February 15, 2014 don't see the point in poncing about turboing a zetec if you're only after 180 bhp tbh. much easier and cheaper to fit a cvh turbo lump instead. Link to comment Share on other sites More sharing options...
SLEEMAN Posted February 15, 2014 Share Posted February 15, 2014 for a turbo manifold why not focus rs turbo look here http://www.ebay.co.uk/itm/Ford-Focus-Rs-Mk...=item25897a6903 that's pretty cheap! that would be a start just like Stu'd original gti turbo! and you have to remember you got to run it on super unleaded when its done! no cheapo 95 rubbish also just look around for people selling turbo converted engines so you don't have to do all the hard work! I know that maybe risky depending on who built it but still maybe cheaper and easier to get it going Link to comment Share on other sites More sharing options...
