Hello Oppo, it’s been a while since my last post but I haven’t been the most inspired lately. I’ve been wanting a little more kick from my daily driver but I have no space to work on my car and despite the fact that I’ve done clutch and transmission swaps on FWD and RWD vehicles my mechanical skills and knowledge are at a dubious shadetree level or less.
As some of you may or may not know I drive a 1995 Polo Fox, 6N1 , absolute base model aside from the 1.3 in it. SOHC, Bosch monomotronic FI (single point.) How hard is a cam swap in an SOHC engine, will a standard mechanic be able to re-time the engine for me after said swap? Are there any possible fueling problems that might arise from this or supporting mods that would be needed?
!!! UNKNOWN CONTENT TYPE !!!
This is the part I’d be swapping in, a cam from an older Polo GT, apparently it’s a direct swap and the cam in my engine (ADX) is the most mild cam fitted into this generation/design of VW 1.3.
I’ve tried searching forums for more info, but there’s really not that much. I’m just looking for a bit more responsiveness and happiness to rev out of my current engine, upgrading to a different car isn’t really in the cards for another couple of years.
Any help, advice or shitposts are welcome.

Well here’s the timing stuff, seems dead simple to me.
Translation:
Cyl. 1 in TDC/compression top. loosen belt tensioner and remove belt, don’t spin camshaft with engine at TDC, valve/piston contact. Tensioner turns untill aligns with mark on rear plate(small drawing), tighten tensioner. Spin engine 2 times in it’s rotation and control the timing marks. Push the timing belt withy our hand, and make sure the tensioner returns to mark when you stop pushing.
As for the swapping part, it’s normally pretty simple, the bearing caps list as 6nm+90 degree tightening.

I’ve never messed with timing, pretty sure it’s not an interference engine but it still worries me. That helps though, thank you. Is this something that could just be done with a jack/jackstands and only a single (dutch) parking space worth of space to work in? It seems like it would be.
I’m safe without a timing light? Or is that something I’ll likely need to invest in as well.
Do apologize for the flood of questions. Definitely giving me more confidence though.

No idea about timing light, aren’t those for rotor-based ignitions? Even then, should only be needed IF you need to take of/remove those parts. I have not looked or messed with the polo’s sadly.
Just jackstands sounds doable, but you’ll be down in the dirt i’d guess for some parts of it.

Oh and best advice, hook up with a friend who’ve done stuff like it/that specific before.

Honestly, that’s how I’ve learned everything I know about wrenching. That and making mistakes. My car still uses a distributor, but I don’t think I’d have to touch that. Thanks again!

Any time you mess with engine internals you want it at top dead center (can’t think of an exception). There are usually clearly labeled markings.
May look into a new cam for my old truck this summer.

Your engine design is basically hopeless without the port fuel injection system and ECU tuning to take advantage of the higher flowing cam
