lq4 swap questions

2006 LQ4.
I have no clue what direction I will fully go, but looking to do 11.50s or faster.

All what sensors to keep
Whats the cheapest accessories drive to get (no ac)
Can I use a corvette oil pan (umi k member)
I hear about the flexplate uses a spacer can I just use any ls flywheel.
Will the stock starter work with the t56.
Will it be cheaper to buy a P&P aftermarket harness and self tuning pcm (I have no cheap source)

Can a turbo from a 96 3500 6.4l diesel work or too small.

Front O2s, TPS (in the throttle body), MAP, crank & cam, CTS, MAF (some tune that out of the system), IAT.

Used.

Maybe, but I've never heard of it being done. I would think the wings would interfere with the f-body A-arms, but I don't know that for a fact.

Only need a spacer if running a 4L80E or a pre-LS transmission.

Stock LS1 starter with a LS T56 flywheel. LQ4 starter won't work.

Cheapest will always be a factory harness you modify yourself.

No clue. You'll have to inquire of the PA crowd.
