I have jst read that you can put the top of a KR 1.8 16v onto a Audi 80 2.016v block which would then give around 190bhp. jst wondering if its true?
-
yes you can ditch your old 1.8 bottom end and replace it with blocks such as the audi 80 9A. However it will not give you 190bhp. Other mods are needed to achive this power. i.e gas flowed head, cams etc.
-
what power we looking at with jst the bottom end? 150? but with more torque i presume!
-
Maybe 160 with LOADS more torque. Its a very worthwhile mod!

cheers m8y think i've jst gave myself a nice propject :wink:

did u mean 6a block or 9a?
-
Im not sure what your asking mate. I did say 9A in my post which is what i have on my KR engine. A 6A block may also do the trick but im not sure. The 6A might be for the 8v? Im sure somebody will clarify this.
-
6a would be fine.
My 9a/KR got 175bhp/150lbs with just head work.
-
So to clarify... You can also use a 6A block on a valver?
-
The 6A engine can be found in the Audi 80 2.0 16v's of the early to mid '90s. This engine is basically the
same as the 9A except for the fact that it is fitted longitudinally in the Audi (as opposed to the transverse fitment favoured by VW and Seat), meaning that a few more parts need to be swapped over onto the 6A in order to get it to fit into a VW than would be the case with a 9A. This fact makes the fitment of a 6A slightly more complicated than the 9A or mk3 ABF, but has also meant than many more of these engines have survived in scrap yards and have not been snapped up for conversions by other people. There are plenty
of these engines available in normal (i.e. non-specialist) scrappies and you should be able to pick one up for under £200. A further benefit of these engines is that the cars they were originally fitted to were not out and out sports cars and have consiquently not suffered from years of thrash. All good news.

Here's a snippet from the info I have on Audi 6a lumps, you'll like the bit I've highlited in red :smug:
F it t i n g K R c a m s a n d c h o o s i n g a n i n l e t m a n i f o l d .
One thing that makes the whole job worthwhile is to put the cams from a KR into the 6A. Those fitted to the 6A only allow it to produce 136bhp (which is less than the KRÂ’s 139bhp) although the torque is much better. Fitting the cams from a KR to the 6A can see the engine get 170bhp with upwards of 150ft/lb torque if properly set up. These are a straight swap, but remember that the cam bearing caps are matched to the head and not to the cams. The cams wonÂ’t turn if you get this wrong!
