Welcome to the forum guys.
Wow, that an interesting engine Serge. Unfortunately we didnt get the GK engine in the UK version of the Mk 2 GT (coupe S).
Did they orginaly have mechanical tappet heads, or hydraulic ?
Some interesting polo's there.

they've mechanical heads original ,but the hydraulic heads are comparing with the fluid canals like teh mechanical ,even so on the 1.4 and 1.6 engines

the gt was only in the uk sold with an hydraulic head mh 55 hp engine .
ther is an option to het more umph out of that engine .if you flatten the topsite from the body engine for about 2mm ,evenso get 2 mm from the top from the pistons ,deepen the valve seats in the piston for 1 mm.
flatten the head for 0,3 mm .take a 3f camshaft .tahke a pierburg2e3 carb from a golf mk2 1.8(straight swap).the intake and cylinderhead ports should be grinded .let it run on the original ignition with fuel ron 98.should give around a 80 horsies with standard stuff .imagine with a faster cam what it can do

Well I can´t stay behind:
Basic AAV engine with golf 1,8l throttlebody (motorcode RP) and intake from a GK coded polo engine, grinded for better flow. and the allready mentioned induction kit.
Exhaust is a homemade midpipe and only a Remus backbox
Still to come 3f camshaft and G40 outlet manifold and a G40 downpipe with empty cat. After all mod´s are done it´s time to modify the ECU for the last bit of extra power.

yes that's for the next year.
the trottle boddy's are from a motorcycle suzuki gsx-r.
we combinated with a home made intake,272 or 280 camshaft.
the first thing that we modifited, are de brakes.
the front system will be upgraded to G40 brakes.
