My engine is in one piece again!! Trans is even bolted up. Here's a list of some of the specs:
Top to bottom.

Gutted 200sx intake- emissions removed, 60mm T/B
Ported lower intake.
Isky 280deg .485" cams. Morgan's (or knock-offs) cam gears set at 0* now
Ported 85e heads, SS valves JWT springs.
260cc injectors, 7300rpm rev limit. Stock NA tune at present.
10.8:1 BRC pistons. Lightened to 380g (they were 395 and could be lightened another 20g or so but I dont have an end mill) All balanced to within 1g by machinist. OEM rings.
Eagle rods 585g
Entire rotating assy balanced
Nissan OE graded bearings
87 turbo A/T oil pump. ported. Radiused corners of entire oiling system.
5qt gated oil pan and moded p/u

Hand-made, tig-welded equal-length, step-up headers. By Jeff at Teamthump $$$
Hybrid 71B/71C close-ratio transmission. 3.0, 1.8, 1.3, 1.0 .77
Thats about all I can think of at the moment. Now the pics:

Oh man, I like that motor, a LOT!!! I think you have built "the correct" motor for a hype 510.

UPDATE:
Well I got everything in, bolted up etc etc. I started it up and it runs great, maybe a little lean, but then the gas is a year old. It actually drove a few hundred feet from the shop to the parking lot. I have a few bugs to iron out but it should be completely road-worthy in a week or so. Pics and vids soon!

this is no small task when you consider all that has been changed:
injector style and wiring,
block/crank/rods
pistons made to my specs
hybrid trans, new driveshaft, mount and shifter type
belt drive V to ribbed
oil pan
I'm sure there's more too. At least its all coming together

Those are beautiful headers, but will you be able to remove the transmission without removing the headers?

Probably not. Fortunately the trans is working great. I have about 200 miles on it so far. Its running a bit lean still and I tried another MAF sensor but it didn't help. I'll check fuel pressure later this week as it is also running a different fuel press regulator than before as well.
