What is an ABF 16V?
Back in 1992 when the 8v GTI was released in Europe the 112BHP didn't cut it, so VW's engine division was asked to design a 16v motor for the Mk3. After rolling out an 'old' 16v based engine at 130-140 BHP they were asked politely to go away and come back with a better design, as the competition of the time were all up around 150+ BHP (Vauxhall Astra GTE 16v & Ford Escort RS2000)
After a further couple of years the ABF was born, but was producing nearly 170 BHP. This did not please VW as the VR6 was only kicking out 174 BHP, so the ABF was choked by the ECU to produce 150BHP, but maximize the torque. Also the tax brackets / insurance brackets in Europe / UK were working against a 170BHP 16v'er...so it went on sale in about 1995 with 150 BHP / 135 lb-ft.
Thinking about this story, it makes sense, as a simple re-chip yields 170BHP and 160+ lb-ft....so it seems that the ABF was always designed to produce 170 BHP anyway...hence the large gains.
This engine was always developed to be the basis of VW & SEATs rally cars of the era, so it was designed to be tuned to 280BHP.
What are the specs?
Displacement 1984cc
150 Hp at 6000 rpm
18mKg at 4800 rpm
Cam timing 1-39/40-1 for a valve lift of 1mm
What are the differences between the ABF head and KR/PL
serpentine belt accessories
digifant 3.0
Rods are 15mm longer(159 vs. 144), block is 16mm taller(236mm vs. 220).
Different cams
narrower intake ports on ABF/9A than KR/PL
better exhaust ports on ABF/9A than KR/PL
ABF uses 35 mm long valve guides, KR/PL uses 38 mm
ABF uses different inlet and exhaust valves (95,5 and 97,95 mm long) than KR/PL (95,5 and 98,2 mm long). I'm going to check what the difference is between the valves except for the different length on exhaust valves.
ABF uses VR6 valve spring retainers
Longer cambelt for the 16.5mm higher block.
ABF uses a welded tube exhaust manifold, KR/PL uses cast exhaust manifold
