Hey all,

So my brother and I are about to embark on the engine re-assembly of our resto project. Here's what we're starting with. Basically it's the 1.7 from our '72 but we've got new 1.8 pistons and cylinders and all new wear items, seals, bearings. A new for us (used) crank (polished) and we had a valve job done.

We also rebuilt the Weber 34 ICTs the car came with.

Hey, so did you need to mod the case to take the 1.8 Pistons and cylinders?

Are they a slip in fit?

Please don't start putting things together just because they fit. If you are trying to adapt a 1.7 or 1.8 motor with larger P/C's, make sure everything will work together.

AND get Jakes video....

yep, the case needs no changes to fit 1.8 cyls... though I don't think you get anything from them... the 1.8 had less HP than the 1.7...


1.7 heads DO need to be opened up to put the 1.8 cylinders in though...

Thanks guys. Indeed we have the minifridge with beer. We did have the heads worked to accept the bigger pistons. Since the cylinders just bolt on to the block there is no need to do any crankcase work. We were under the impression the 1.8 made less hp because it was a version made to meet emissions standards. And, well, a bunch of that stuff was "weight reductioned" out. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

We were also told the 1.8 heads have the largest valves, and it would be a benefit to use those (but we ran out of money and time). Is this true? It seems odd that the 1.8 would have larger valves than the 2.0.

No, 1.8L heads have 41x34mm valves as the 914 2.0L heads have 42x36mm stock.

Hopefully you are replacing the cam with something better than the stock pos and new lifters to match the cam. (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif)

Yikes, It's a lot of work to have to redo. Do it right the first time and do it once. If you need something soon, find a runner in the area and put it in for a while, then take your time on the rebuild.

Careful, the stock cam is designed for the fuel injection system period. To take advantage of the carburators, you should get a cam designed to maximize their potential.

Good luck with the build and keep us updated with news and photos.
