1990 SW20 Turbo Parts for Restoration

Hi guys,
 
I'm doing a partial restore on a 1990 JDM Turbo and I'm looking for a few stock parts that people doing upgrades would probably be throwing out.
 
I need:

• a support bracket for the cast aluminium air tube that connects the turbo to the intercooler
• a VTV valve (the one sits in the bracket under the stock BOV)
• a set of standard springs (to replace current lowered springs that are too harsh for my liking)

Any help would be appreciated.
 

Thanks,
I do still need them.
