Winter is coming and I don't really plan to need my Polo that much Thus I'm thinking to invest some time in tinkering with it.
I will soon start a build thread for it, as I initially got it just for a backup car, but now I want to "play" with it . Before that thou, I wanted to ask some questions, about things that I'm not fully clear on
I do have some power issues with the car. The clutch cable and the clutch itself were garbage when I got the car, and I fixed them, but the shop didn't do a good job with the clutch cable and I'll need to replace it again - the clutch pedal is very heavy, noisy, sticks often and doesn't release smoothly. Still when I compare the car to my brother's Polo (same engine but AUA), there is very noticeable difference in how the car accelerates and how much easier and quicker it revs - it did also have clutch and cable changed at about the same time. It is good to mention that the AUA Polo hasn't seen proper maintenance in about 3-4 years, while in the past 2 years it was running with a faulty head - losing a lot of oil and coolant regularly. Still after a simple head gasket change, clutch and cable it runs times better than the AHW Polo that seemingly doesn't have anything wrong with it... Both Polos have their Cats removed, where for the AHW I have a whole new exhaust, except the manifold.
So, either way I do plan to service the engine of the AHW Polo. And I do have the bold idea of trying to do it myself, mostly as a challenge
What I want to do:
1. Service the head:
- new set of inlet and exhaust valves
- new valve seals
- polish on the head and the valve beds - outsource
- new gasket
- probably just cleaning the cylinders and changing the rings
3. Timing belt
- belt, pulleys, water pump, etc.
Most of the things above are fairly well documented, and I shouldn't find it very hard to do, but I do plan on upgrading the engine in the future at two-three stages, and wanted to know if I should plan ahead, if I'm opening the head
Stage 1 - GTI upgrade
I already have inlet and exhaust manifolds + throttle body from a GTI. I do plan of adding them after servicing the engine. And as far as I know I will need to remap the ECU for the new throttle body
Question 1: Should I even bother with trying to remap the ECU myself, when the change is only the throttle body. An ECU tool is fairly cheap and I think it should be a nice entry level job
At a later stage I might go for the supercharging fun, but wanted to ask about the engine mods that I see being done around it - fast road camshafts, decompression plates, bigger valves, etc.
Question 2: Should these things be done to the engine only when adding the supercharger, or they can be done earlier?
- are these the cams I should be looking for?
- can somebody quote me which bigger valves are being used in such a set up
- would a CLK W208 supercharger do the trick?
Question 3: If I decide not to go for airflow mods, should I just add better cam shafts to the GTI mod and call it a day? Do the new cam shaft (either from a 101hp 1.4 16v or a fast road one) require a remap?
Note: I was thinking about an engine swap, but I decided to play with this engine. I do have a bigger engine car and I am not really looking to make this Polo be something crazy.
I need to buy some big end cap bolts for 16V AFH.
Anyone know the size of them and tensile rating required?
