you guys are thread-jacking. I thought i had looked at all kinds of info, im sorry you feel im attempting this ass-backwards, but hey we all start somewhere i guess. I thought i had a pretty concrete thing going here. i knew i needed the fuel/spark control. Oh well i guess, i will attempt and just try and ask questions when i get stuck i was looking for a cam setup as i type this. I will keep on searching. and start building soon.

Tony D - "But like all things, people using a stock bottom end tend to be trying to get a lot for nothing. And cheaping out tends to make things break. Usually (I'd almost say always) from detonation." I dont see how im being cheap, by using the bottom end....that makes no sense to me... Im only changing the head for better flow, and a turbo set up. letitsnow - wow. was the 280zx CR 7.4:1? Thats insane! So, With the P90 head, and a cosmetic head gasket, id be looking at that CR? So then cramming 20 pounds of boost would be needed...now to research a turbo...lol thanks for that info, i really had no idea the CR would drop that far.

emeraldlion - thanks buddy. that makes sense, i was just more concerned on reliability of internals really. Like i know a VG30DETT stock injectors cant take more than 17 reliable, and how the 2.2 Ecotec in SS Cobalts have forged internals stock and cant take more than 420 hp, and the wrist pins in VQ35DE's cant handle more than 450hp on daily consistence. Thats more or less what i was trying to get at. letitsnow - sorry i should have clarified that i would run the stock 280z pistons. At 7.9:1 compression, you NEED boost to keep the motor running more or less lol

Ok after months and months of research. and hunting for a Datsun. I have found one, and preparing for a simple yet effective build. What do you guys think of this? This is my motor stuff, i also will be doing fuel mods and all that fun stuff! L28 Block (280z) L28 Crank (280z) L28 Rods (280Z) L28 Pistons (280z) P90 Head (280zx) 2mm Head Gasket Full rebuild, bearings, gaskets, seals, and rings. stock compression on the 280z is 8.3:1, so with the thick (2mm) head gasket, Would it drop me to 8:1 CR? Can the stock 280Z rods handle 20 pounds? Thats my max, and i cant find where anything has stated the bottom end strength of the 280z.
