914World.com _ 914World Garage _ 1.7 too a 2.0 F.I. budget build up. what to swap ?

Posted by: insipidCarrot May 8 2005, 08:35 PM

I am looking to build up my 1.7 on a budget, mainly I want to punch it out to 2.0 with a higher compression and possibly a cam. What do I have too swap from the the 75 2.0 to the 1.7 ? Any suggestions for a set of pistons, stock bore or close with a higher compression and what about a cam that will work with the F.I. for the street. I am assuming the 2.0 head will have to be used and obviously the jugs, but are there any other pieces I am forgeting ?

Just, rebuild the 2.0, it will cost you more to turn the 1.7 into a 2.0, first off, you'd have to have the 1.7 (90mm barrels) case opened up for the 2.0 barrels (94mm), you'll save that money, using the 2.0 case. The 2.0 may or may not have a windage tray, but it will have the shelf to install a windage tray, where the 1.7 does not.

Just a couple of things to think about.

Nah, the 1.7 and 2.0 cases are the same and you don't have to open up the case cylinder bores.

...and pistons, and you should use the 2.0 heads too...

just rebuild the 2.0... change the rings and cam(if you are going with carbs, or just want a hotter cam)... or you can put in 96mm pistons and have an instant 2056... the 96mm pistons are a better value than euro-spec flat top 94mm pistons...

but for a budget build, just change the rings in the 2.0, and have the heads freshened...

where did everyone get that you have to cut a 1.7 case? you have to open 1.7 heads for bigger pistons, but you don't have to cut any TIV cases until you try and run ~103mm pistons... the cases were ALL the same...
