pistons???? also, think about using a 234/204 block, they are made of a little bit stronger material,, if i do a big build, i prefer to pull Ng900 NA motors, and re-use there block. they are super cheap, and gennerelly in nicer shape

For better oiling, see "yellowjet's" viggen build thread. They used a b204 timing cover and oil pump, TIG'd on an extra boss for the p/s pump bracket

If you decide for a top mount... Hy35 is probly the biggest you can fit without modifying the hood

so updated the list after speaking with JZW yesterday. and sorry mikeD pistons were just forgot on the list. i'll be going with coated bearings per john's advice, as well as the uprated race valve spring's to rev out a bit more. as for turbo i think finally set on the Hx35 as the best streetable option. with the 12cm housing. i really want the reindeer manifold. any ideas on a source? vigge? or should i just have something custom fabbed? soon as the block's together i'll post some pics and can start discussing thing's more for fuel ect...

Why would you O-ring a multilayer headgasket? That's not recommended. That's really only something you do to old style headgaskets made before a Multi-layer design was available. I'm with Viggi in the logic of the headgasket is the "Fuse" for the engine. If the fuse doesn't Blow when you have a severe cylinder pressure spike because of improper tuning, leading to a Severe Knock event, Equals Mechanical damage, Bent rods, Broke pistons, Broken crank etc. Trust me, You really want the headgasket to blow first, in the event of a tuning fail. Or else it's time to buy a New motor and you start all over again. = to much $$$ instead of Fun. If you need an East coast custom saab head builder, Full out machineist, PM me I'll throw his number to you. Also you should replace the balance shaft bearings while you're there as well.

A3 angle valve job changes the face of the contacting surface from around 30 something degrees to 40 something degrees. Depends on the stones you're using to grind with. The problem with changing the valve angles leads to a Thinner valve margin. The valve margin is the Perimeter of the valve that gets Thinner & weaker, More prone to burn. I just Grind the stock valves into the head, Deeper untill I have as close to a Perfectly matted surfaces Valve to seat as i can get with almost no pressure loss. This recesses the valves a little deeper into the head but causes such a Tight seal that the engine becomes more efficient than the "Other guys who sub there work can get"
I do my own tricks after the machineist is done to make my stuff as best as I can possibly make it. It shows in basic measurements like engine vacuum, & why tuners want to know why my engines make -30 inches of vacuum vs. everybody else's fluttery -18 to-20 inches. I am a hardware guy- I leave the software tuning up to the tuners. With proper Hardware assembly & Professional tuning, You will have monumental results.

thanks guy's for the thoughts. my engine machinist was the suggestion to o-ringing. also discussed it with JZW. this still may or may not happen when they start the machining next week. as for 3angle also a suggestion from machinist. they build many high hp race motors and the cost was very little when quoted into the rest of the work. maybe some other's will throw some comment's and suggestions on these two things. As far as tuning i've really been discussing the motor build with john, i've called numerous time's to discuss my concern's or ask questions on what the best,strongest route and also what really need's done for my HP goals. since he will be the software/tuning for it all to make my Goals.
Thanks alot
Don.
