Hi,
long time ago since my last post.
I get the clutch issue fixed but did not found a solution for the strange power behaviour. I change the support point for the clutch cable and use an original self adjusting VW clutch cable, which works until now. But in summarize the sinter metall clutch makes the car worse and not better. With the clutch it was not longer good to use as daily driver and than also one or two glow plugs stoped working, so the car starts very very bad. With all the issues (power behavior, clutch, start issue), there was a point in Oktober last year, where i not like the car very much, bough a very cheap 1992 BMW 525 TDS as new daily driver and parked the car in my garage (unregistered).
Before that i have build a better intercoller pipe setup:
Before i take the number plates off a make a last quick drive through my favorite roads and have to commit, that even with that problems that little car droves just fine (the strange power behavior only occurs during 1/4 mile runs, not during normal quick driving) and has had enough power to make me smile.
Since oktober the car has sitting in my garage and i did not know what to do with it, i though i will sell it, not sell it, sell it, not seel it (i think most of you will know these situations). And than short before christmas i build a performance pump for a VW caddy mk2 with the lasted eddition of the aaz engine (with electronical advange timing) and start to realy miss my golf.
The caddy get the perfromance camshaft here from the board, the stock lift plate (3,05 mm) and an Ø11mm plunger. The guy also add an HKS EVC4 boost controller, and swapp the gearbox to an long geared 02A with a Ø228er cluth (the stock cluth was hopeless) and a lighweight flywheel.
The pump is absolute at the optimum point from the lift plate - plunger setup and i also think that that electronical controlled pump timing could be an improvement against the hydraulic timing control.
But back to my golf, after starting to think again about the golf i decided to get a new head done, because the other one still has that crack from porting. I will also swap the turbo again, the Switzer S2B will go in my E28 and the golf will get the S2A again, which was installed during that 190 hp dyno run. But i will swap that turbine housing to a bigger twincroll one with T3 flange instead T25 flange and i will keep the QSV, so i hope to get very quick response from the S2A combined with the ability of high bost levels with relative small backpressure.
The new head is allready ready cleaned, flattended, ported and poilsh. Still to do is, to pull the old head, get the valves out and to regrind the valve seats of the new head in accordance to the old valves in regard of the needed gap between the valve head and the piston.
Here is new head during the disassemble:
and this is how it looks now:
