D17 build
Hey guys new here, I've read a lot of stuff online about this and searched but didn't find the answers I needed. So I have an 03 dx. Currently has xenon body kit, aem cold air dc header and vibrant axle back.. No real upgrades. I want to build the engine for boost but had some questions. Would upgrading the rods, rings Pistons, bearings head gasket and studs be good enough to boost? Or do I have to do valve springs cam and everything else? I'm gettin an eBay kit and the turbo rebuilt. Also to replace the rods and Pistons can I simply remove the head and oil pan and unscrew them through the oil pan and pull them through the block? I'm also upgrading the intake manifold and injectors and going to run the k pro engine management setup. Also do I have to get the head resurfaced? And can I just get the stock spec of Pistons or do I need to get low compression? Thanks a lot in advance!

Re: D17 build
You don't need to upgrade the cam, but if you decide to go high boost, you won't be able to utilize the turbo's full potential. However, you'd need a d17a2 head swap. I don't believe there are any cams for the -a1.
Upgrade your fuel pump. You didn't mention that anywhere. You may want to do a return style fuel system conversion
You could remove the pistons that way
Compression on the D17A1 is 9.5:1. You should be good. If you wanna run more boost safely, I'd drop to 9:1 or 8.8:1.
Really, you should be asking yourself what your overall end goal is. Do you want to run high boost or do you want something like an 8psi DD? A high boost build and a low boost build are going to be very different. Realistically, with a good tune you can run 5-8psi on a stock engine and upgraded injectors. If you beef up the internals, though, it'll play nicer. There are far too many variables involved to be able to answer "if I do x, will that be fine for boost?"

These are the rod/Pistons I'm planning on getting, http://realstreetperformance.com/Wis...75mm-8-81.html
would any of the specs change or no? Such as bearing size, piston size so on?

"I want to safely push as much boost as possible without blowing the engine on nothing but the upgrades I mentioned"... Doesn't work that way don't be cheap.
What about a new trans? All that boost...
Intercooler? quite common with turbos
Are you going to get a turbo manifold?
Drivetrain?
Wideband 02 sensor
MAP sensor
How about brakes?
Sounds like you haven't done much if any research and want to spend barebones and what was the phrase? "Push as much boost as possible"
Yeah ok
