  1. It depends what are your goals with engine and of cause budget. Standard pistons are weak, those can take around 220hp with good knocking control. Standard turbo is max 220hp, peak could be bit more but starts too much heat. Standard head is not first limiting thing, but there is custom head and cams available. But there is long storys here in forums about these things. Just ask and lets see if can help.

  2. As I sayed needed to slow a bit things, but things started to hit me. And it did get even worse (some might think this negative way) :D I went crazy and bought this from

    Japan last summer. maserati 3200gt. Will continue with 505 next summer but I need to reduce my 505 parts storage with strong hand ?

    But its very good at you decide to keep this up and running. I was allready worried a bit when I did not find site. We are not many in globally having this 505 hobby.

  3. hitting heavily due personal reasons.

    So, I'll sell a parts of rare old and new stock items for 505 (specially for turbo). danielson heads, gasgets etc... Listing is hard currently, but ask and I'll look.

    1.st add. Also new original front shock internals and a lot of other parts. Ask and I'll have a look.

  4. About n9t (9n2 and other same family) head problem. N.A heads suffered same issue but on n9t it has more heat load on exhaust side. And due N.A design there is narrow edges on exhaust valve seat and water hole, other problem is casting material (aluminum) and air bubbles and residues. This info is coming from welder who has welded over 10000 alu heads for repair. But once its repaired properly it will hold (seen only one n9t head with crack on welded one). Sodium valve was not solving problem thats why it was stop used in n9te (86 ->) models and it was costly valve.

    I must bit disagree about parts availability, depends how to look it. Surely parts not found every corner shop and there is rare parts. But so far there is no part which can not be found for engine or car. It could take time and effort but usually these are not daily drives any more, I have seen many younger cars having way worse parts problem even cars made after 2000.   

  5. In case some one needs special over size bearings I have some sets of 0,1 0,2 0,5 0,75 and 1mm. remeber at if there is one badly worn bearing you dont need to grind all bearings on same over size. Just a possibility to save some engines cause of rarity.

    Some conrod bearing sets also 0,75 and 1,0mm

  6. Here is picture of repaired head /welded and surface straightened.  plug holes and combustion areas not grind in correct shape yet. But this is sample how it should be fixed to last. Problem is is on those 2 and 3 exhaust ring cracking towards water side, its very narrow place and heat difference is high. Welder said at there is bubbles  and residues from casting and its not so good and constant aluminum mold which can be seen when welding head.
