Thanks for all the comments! The sandwich plate is working fine, haven't had any leaks or anything and the turbo is getting plenty of oil.
As far as cost, I've got alot of extra stuff so my total is inflated, but I don't think it would be unfeasible to do it for <$3k, especially if your 7M is already modded as most parts will transfer over. I also got about $2k for all of my stock 7M stuff (2 motors worth).
Basic swap w/some maintenance items would be:
Motor $200-$700 (paid $150 for mine after selling extra stuff)
jza70 bellhousing $300
1jz flywheel $130 (what I paid for mine), lightweight ~$350
BIC motor mounts $175
1jz PS Hose $65
1j ARP fw bolts $32
ARZ oil drain fitting, tap, line/fittings $70
DM FPD delete line $60
7M Plug Wires (1 set I had fit, new ones from DM were too short for the 2j) $60
Plugs $10
Fluids (coolant, syn trans/diff, oil etc.) $80
Serp Belt $15
TT headgasket, valve gaskets etc. $150
Timing belt $25
Thermostat $10
FMIC Kit $300 (mine is a modded Godspeed 7M kit)
Type-S BOV $35
935 DIY Exhaust w/cat, flex pipe etc $350
Downpipe parts $150
MP T70 $550
T4 Manifold $120
50mm Wastegate $80
Authentic HKS WG spring $50 (the 11psi spring in my knockoff WG was holding about 4psi :biglaugh
4AN oil feed line $55
All that comes out to <$3k assuming you already have a 7M ECU and harness, clutch etc. assuming I didn't miss anything. You can also pick up the
XSPower 2j turbo kit for $1650 instead of piecing everything together
Any fuel mods like Lex/550s and SAFC or MAFT can transfer over. Can also use a 7M exhaust modded to fit the DP and IC kit if you use the stock IM on the 2j, just have to cut the 3000 pipe portion a little.
