I have never rebuilt my engine, so I don't know about the necessary parts.

But I would like to ask a favour. Can you list the price of the parts as well? That way someone will know the average price of the rebuild.

You need some rods and pistons, I also will be on a low budget build to safely run about 12-15 psi
This is a low budget build hence no pistons or rods. If I had the money id get an 07 crank with forged rods and pistons. I might just get the oem rods short peened if possible.

ABSOLUTELY!!! This build thread will be completely documented from cost to build. ;)

Boost isn't very reliable with the oem rods so..

I am with teeke. You can't really call this a 'reliable' build if you're not going to reinforce the parts that take the most strain.

It will end up being a simple budget boost rebuild.

Basically it is lol...... with a few upgraded points that are weaker on the qr... If I had the money id deff do some different rods and pistons but im broke and on a budget....

The question of reliability is how much boost, which turbo and tune.
All very good questions.

im looking for a quick spool up and as much psi needed for safe, reliable, 300whp-350whp anything more is a plus...
the turbo ill be using is the same 1 a turbonetics t3/t4 dual BB turbo.
It will be tuned on uprev via a reflash tune from Joe At 2J-Racing. Its what im already tuned on.

If you're gonna use stock rods and want over 300whp..good luck to you, you will need it :lol:

But seriously probably 12psi will get you within that bracket on that turbo so I would suggest get atleast rods and use stock pistons I guess.

300whp has been done on stock rods... and has lasted... the weakest point on the qr other then the rods are the poor piston rings/lands, the pistons themselves, bearings and rod bolts..... I plan on upgrading everything besides the pistons and rods because my budget wont allow... Which really sucks... If things change id deff upgrade the rods/pistons.

This is not a journal bearing turbo, its a dual ball bearing turbo.... So I should reach 300whp by 8-9psi.....

Ball bearing or journal will make the same power as long as the compressor and turbine wheels are the same. Most spec v's run such low boost levels that the difference in spool up between a journal and a ball bearing turbo is insignificant.

Take ur time and upgrade to forged pistons and rods , u will thank urself for doing this . Let's say u crack a ringland on a stock piston like myself and many others have and then that piece will damage ur valves , and will tear ur turbo to shit . spend the extra $900 that's critical for a boosted application , otherwise I assure u that u will rebuild that engine very soon

If your budget doesn't allow it now, then save up a little longer and do it right the FIRST time.

You mention that over 300 hp or more than 12psi have been accomplished before. Great. But what about those that have failed?
Don't be one of those that failed just because you rushed your rebuild and took corners.

Think about it this way. Most of the people who pieced their turbo kit together to 'save money' will most likely tell people to just save up and get the kit.
Why? Because it will end up costing you more in the long run.

This is the truth, we are victims of the turbo kits lol
