Nice man! Just finished a 4th gen swap on my 165 also. Went pretty flawless too however I have an idle problem also. I setup an OBD2 Bluetooth on it and it's showing a fault in the IAC circuit. I can't seem to figure out what it is either. I cleaned it out and it still has issues. It will idle really high or really low and randomly it will work fine. How much boost are you getting out of the stock setup? I'm reading about 9psi however I heard the ECU cuts it if it doesn't get a signal from the trans being its an auto ECU.

Right on man, its always nice to hear of some more 165 love. Mine is doing the exact same wonky idle stuff. Low, high, normal, rough blah blah. Its getting annoying. Before installing my boost controller, I was seeing 8psi with the wastegate. I now run 14-16psi with an Apexi AVCR. Its a beast for sure now.

Hey man, by chance did you change out the timing belt when you did the swap? Kind of random but I found out mine stretched to hell after only 5k and I changed it out before my swap. I wonder if I put in a 2nd gen belt instead and maybe that's causing an idle issue.

No, I ended up using the belt it came with. I know PrimeMR2 sells a Gen4 timing belt. I just cross reference the part numbers they list on their site, and get it cheaper from somewhere else.

Update on this!! By any chance, did you go 5x114.3? I saw a car that looks like yours with Supra wheels online somewhere.

Hey what's up sir. Yeah, that's my car. I did go 5x114 lug pattern. The car has been off the road for a while so I can perform all the updates it needs to stay running lol.
Those are some rollers from my Mk3 Supra. I picked up some TE37's for the Alltrac, and I'll have them on soon.

I have not been very active on here with the updates, so I'll try to provide a little info. I took the car off the road to replace the shift cables, and install a ST205 transmission.. Next thing I know, I'm gutting the engine compartment, going E85 with an ECU master EMU, Wahlbro 450 pump, 3rd Gen exhaust manifold with a BB GT35... Those are just a few items...
- I pulled the engine and replaced the timing belt and tensioner. I wanted to clean everything up, so I pulled everything apart and had the intake, exhaust, and water pipes all ceramic coated.

I swapped to a 5x114 lug pattern using RAV4 front hubs and RX300 AWD rear hubs, using the Celica bearings. Then I installed ARP extended lugs. So now I have new wheel bearings in all 4 corners. This picture shows the Porsche Brembo calipers that I'm using with Subaru STI 326mm rotors. I purchased the kit on eBay from an ST185 owner.
I have it all bolted together now, so I'll provide more pictures later.

I will provide more pictures soon when I see the car again. The car is at a shop in Phoenix so they can fabricate the custom downpipe, exhaust, and wastegate routing. I'm also using a larger 12x24 alloy heat exchanger for my W2A intercooler, and running a Mishimoto Radiator from an ST185. The front of the car at the core support needs to be modified in order for it to fit the 165.

This is pretty much what the unfinished car looks like right now..

WOW!! Loving the progress. 4th gen set up looking good. You built the bottom end as well? Similar set up to what I want to do with one of my ST165s going Gen 4. Do you have the ET of the wheels once you do the 5x114.3 pattern? Still debating on going 5x114.3 in my cars. (Too many Alltracs
