Hey guys, I need some advise about my set-up. Its a d16z6 with vitara 75.5 custom legth I-beam rods, the block have been milled 0.020 under. The head is just rebuild with top line valves, zex springs and a two angle grind. Now how will this spool with a to4e 60a/r 63a/r turbo along with a cast manifold with centered wastegate port. Heres some pictures



pretty shitty pictures. Mybad

I havent started it yet. u think its gonna spool the 63a/r turbine to full boost? Should I be looking for something smaller ? Like 57trims?

If you have milled the block 0.020" your pistons will stick out of the bore 0.018". If you have a 0.030" headgasket you have 0.012" piston to head clearance. The motor will not last long.

I would like to see a PTH clearance of 0.040 at least. You can either run a thick headgasket and kill your compression or get the pistons machined

Heres what i had to do on my y8 with 0.010" milled off the block. I took 0.020" off the pistons and run a 0.030" headgasket.

Umm. The piston were still in the bore itself, not sticking out by any means. But why atleast 0.040 pth clearance? Can u explane please. I thought milling would higher compression? And plus I had too, the surface of the bores were uneven where the bores meet.

light year= how far light travels in a vacuum in one year
Bingo! Thus being a measure of distance.

I would assume so you don't have any valve interference issues. And milling the Piston will lower the compression ratio but it will lower it less than running a super thick HG.

Someone correct me if I'm wrong.

Yeah, so 15 light years = (distance light travels in a year) x 15 years.
So you travel 15 light years in 15 years.
Correct. Hence why when refering to other planitery bodies people say it's X light years away.

If you feel like traveling 299,792,458 meters per second, yes. :bigok:

(thats 671 million mph btw)

Sorry Sweed, but you're wrong on this one. LY is a rate. Distance x Time.

OP-Just clay the motor so you know you don't have clearance issues.

Ok noob question here, what do you mean clay the motor? Never heard of that

Edit: OP, on the pic of the bottom end with the oil pan off and whatnot, is there a oil pan gasket stuck to the block or is that paint? If its paint be sure to scrape it all off reall well, otherwise theres a pretty good chance itl leak

You use strips of clay on top of the piston where it would most likely hit. Then you put the head on (high cam if vtec) and rotate the engine so the valves open and close as normal. It pushes the clay down then you take it apart to measure how much room you got.
