head work..

  1. #1
    im in the group buy for the newman cams!

    im building a head up 1st then building a bottom end...as i dont wanna take apart my current engine....so i bought my mates old 106 gti engine that bent some valves!

    what should i do with the whole lot???

    porting polishing and skimming head is the obvious...but what else would i wanna do, to see bigger power gains, once cams and and all are in?

    should i go for bigger valves? etc

    *ps im not mechanically minded lol...so help me out here*

    I wouldn't touch the bottom end for now. There's no real point with the PH3 cams. You can change to forged pistons to up the compression ratio a tad, but it's not a lot of bang for your buck. Sticking in tune with the head... If you decide to run iTBs, then the headwork will reap you the rewards.

    So in a nutshell: Stick a big valve head on with PH3 cams. Get the inlet changed to iTBs - DTH ones such as KMS are popular. Get a good ECU, loom, new injectors, some sensors, and get everything put together and mapped. Sounds so simple eh?

    Well i would still stick some forgies in there while the engine is apart seems pointless taking it apart again

    was thinking that too!!

    so run it by me...bigger valves, skimmed, ported, polished, p+p throttle body for now, ph3s and my existing raceland filter, s'sprint 4 branch, custom centre sect and scorp b'box.

    i been told mine is chipped at min, but not 100%, though a guy i kno who remaps cars for a living, said he would take my ecu and check the mapping on it. but if it is chipped or if it isnt, and needs remapped, what sorta power gains etc am i gonna get?
