Hi guys am running gt2871r on 8L 1.8t quattro block is uprated but using stock small port head!
Av got a large port head am going to uprate but not sure of my options and benefits!
I have been having a little discussion on another thread but moved it to here!
At the moment I have:
Supertech tripple groove Nitrated intake valves
Manganeise bronze guides
I know I need:
Supertech triple groove inconnel exhaust valves
And want to discuss:1. Av got manganeis bronze guides, wanted to know if anyone have used them?
2. When do I need new lifters
3. When Donizetti need new cams?
4.when do I need new vvt?
5. Do I need new colets?
6. Whats the gain on fast road cams and what's the reliability issues?
7. Is it worth porting or polishing a large port head?
Heres some pics of my head:
