  • 8v head build up

    Sorting out all my gear for my build up. I have a Autotech 270 cam and a mk3 2l head and I'm looking at the following parts from autotech.

    Adjustable All-Alloy Timing Gear
    L/W INTERMEDIATE SHAFT PULLEY
    SPORTTUNED VALVE SPRING SET, 8V
    SPORTTUNED Titanium RETAINER SET, 8V

    the head has a few bent valves so i need to pick up some locally. Plan to get the head ported and polished etc. also but that kinda goes with out saying

    So basically this a good build up? I have a powerchip digi2 chip on the way at the moment as well as a k&n pod setup on the car already, i'm confident it will make some pretty good power. Is this a good setup anything ive missed? besides the supercharger kit that will be coming in the future.

    Is it a full 2 litre motor you are fitting?

    I had an 2E bottom end with an 1800 head when I was in the UK and that rev'd well without a lightweight pulley on the intermediate shaft. Cam gear is a defo though.

    I don't know that you could rev it hard enough to need titanium parts in the head.

    Mine ran to about 6800 with a longer cam than you are running.

    As an 1800 with the same head it pulled 7700 with oversize valves and std retainers.

        Not heard that before. What are you using for an inlet manifold?

            If I were you, I'll go for a 2.0L block and do up the 1.8 head. Since you already bought all the parts, ignore what I said

              i'm not up for doing an engine change atm don't have the facilities for starters, this should satisfy my power needs for a while yet.

                I have always read that the Mk3 8v heads have a worse flow then a Mk2 GTI head. I am currently building a 2L (AGG) block for my GTI and I plan on using the std EV head as a base for modification.

                I got rid of the AGG head after reading (on clubgti and vwvortex) that it flows worse then the Mk2 GTI heads.

                I am currently running the autotech 270deg cam in my car. It is a very subtle difference, but still noticable.

                What size valves are you going for?

                  OK never heard that, I think it depends on what mk2 head also, as i think the rv heads had smaller valves then the euro gti heads.

                  a little help on this would be nice, dont want to waste my money
