The turbos i cant imagine being more than 100 for the both of them if you look hard enough, the piping will cost me close to nothing as I have a connection in the family who readily has them avaible and is superb at welding. The only things im questioning is the injectors and mass air i might want to go to 42, I will get a used set off the trader here. The most expensive part is the tune after everythign is done. I am almost positive I can put this together for under 700 dollars.
Your going to need atleast 42's, possibly higher depending on how much boost your going to run. Your also going to need a blow thru maf if your doing twins. Expect to spend atleast $200 for a decent set of injectors and a good $150+ for a blow thru maf sensor. Between those you've already reached half of your goal.
Any turbo's you get from a junk yard is going to be in questionable shape. Unless your buying them new or freshly rebuilt, you should expect to rebuild them. Complete rebuild kits are $70 a piece. You'll need to get the turbine shaft rebalanced also. You can get the professionally rebuilt for around $200 a piece. My turbo's were in great condition when I bought them so they did not need to be rebuilt. I did however spend $150-$200 a piece for them (which is cheap for the condition they are in).
Your going to need a bunch of misc. items that quickly add up. Oil feed lines, drain lines, drain flanges, dran fittings, feed fittings, silicone couplers, clamps,
02 sensor bungs, bov, wastegates, boost gage etc.
Good luck trying. I decided early on not to go to cheap on most of the items.
If you do, you'll end up replacing the cheap **** with things that are made to last...efectivly raising the cost of your builup in the long run.
