Need assistance: What it takes to get 200hp on a stock D16Z6
Motor is a stock d16z6 in eg civic
Turbo is Garrett 18g
Right now the turbosmart IWG is set to 10psi which I think is too much for my stock motor. I'm going to order a new spring for it but I don't know what rate to order it at.
So how do I estimate how much HP the turbo will produce per psi

the previous owner was making 330hp at 20psi So I should be able to lower it to 200hp

It's only temporary until I build up my extra block. Im learning how to tune with this so I want to run conservative while doing so

has worked well for me, it cant be exact but its still helpful

I wouldn't bother than. The 18G is TERRIBLE trying to run out of its efficiency range under 10-18psi which is well within it. If you were doing 300-350whp, that's a different story. Otherwise, for 200whp, you're even fine with a SAAB /Volvo turbocharger or something in the 24lbs/min range. Although for a D-series engine, for 200whp, I wouldn't bother turbocharging at all until having some internals installed. That's better left for a B-series swap or something.
It's not the PSI that matters whether or not it will blow an engine but how it's tuned and the internals of the engine itself. You can't make a turbosmart go down past it's spring rate of 10psi, and the standard GReddy internal gate is a 8PSI rod actuator. you can't go below that either.
Stop thinking of PSI. That thinking never works.

turbosmart makes a 4 lb and 7 lb spring. I want to learn to tune with a turbo so I thought lowering the psi would make it safer for the block. It's not really about making power at this point so much as learning to tune with boost and power later with a built block

Listen, you can pop a motor at 2psi with a 15G. As I stated, PSI DOES NOT MATTER AT THIS POINT YET.

difference of .84 in compression noticeable?
I have a Z6 block w/y8 head right not at approx. 9.45:1 CR. I'm looking at doing a Vitara build with custom rods that would put me at about 8.61:1 CR
Is going .84 lower even going to be noticeable?

Re: difference of .84 in compression noticeable?
If you're going to spend the money on custom rods, why not use better pistons and get the CR you want? You're already spending a lot of money rebuilding it, what's another $1-200 on the correct set of forged pistons?

If you know of a forged combo for round that price let me know.

gotta pay to play...I wouldn't bother with vitaras, not gonna be very much fun to drive off boost with that CR especially on a D series.
Then again I wouldn't bother with a D series anyway. The thing with dseries is they are alright when using a stock block build IMO. once you start getting into building the block with forged internals the price between just going to B-series is negligible and well worth it at that point.

I can get to 8.81:1 taking the middle out of a y8 gasket or 9.09:1 with a single layer Cometic gasket
is gaining .49 in compression really worth $90?
