Get compression and leak down test.
I have owned a 350z for the past five years so this was never talked about in our forum. I myself know how to do a compression test, but not a leak down. Would any local shop be able to do this, or would I have to find a Subaru dealer?Get compression and leak down test.
04-14 pistons are all cast hypereutectic.The 07+ pistons are cast, so no bueno.
Yes, but depending on the turbo (I'm not totally familiar with that one) you will still have some lag of a larger WHP turbo.^So this may be a really stupid question, but I'm ignorant enough about turbo motors to ask. Could I detune this setup to put down around 350 whp for piston conservation? For example it is tuned for 18psi, but could I set it up for say 16psi?
It depends on who tuned it. When Cobb tuned my STI Sport was 2-3 PSI less than Sport #.Also if it puts down 398 whp in sport sharp mode what does that mean for the lower modes? This is obviously a new concept for me.
You said he was selling it below blue book. I tried doing quick search of private party value of a 2010 STI and came up with around $26,000 for a car in excellent condition. I could only find the value of a hatch STI since KBB's website apparently lacks the competence to list the correct trims available for a particular year. I'm still not sure, since you haven't mentioned it, how much the car is actually selling for.Thank you and I agree with everything you said, but you are wrong on assuming a new one isn't that much more...try 20K more! I could literally blow this one up, buy a new engine, build it and still come out well under what it would cost to buy a new one. You guys have given me some great advise and info. I think I want to take my chances and probably detune it for around 330-350whp and call it good until/if I ever have the play money to throw some forged pistons in it. Every mod he has seems to be a well respected name brand part so with some luck I'll be safe.
In 2008-2010 STIs were only available in hatches.I could only find the value of a hatch STI since KBB's website apparently lacks the competence to list the correct trims available for a particular year.
Same turbo but built, about the same price: http://www.iwsti.com/forums/used-cars-sale/262631-2009-wrx-sti-wrb-built-motor-brand-new.html
08, built and makes 400/450, worth a look, about the same price: http://www.iwsti.com/forums/used-cars-sale/262885-450-hp-2008-graphite-gray-sti-sale.html
and another one i think is worth a look, also built, only at 305whp: http://www.iwsti.com/forums/used-cars-sale/261015-2008-dgm-sti-hatch-10k-miles-cobb-built-motor-lots-upgrades.html
I just think you should spend some more time researching, there are many good offers you're missing. And the fact that the car you're currently interested has an upgraded turbo and is on stock internals means that there is a probability that the engine won't be running for much longer.
