RB25DET Series 2 opinions / help / and some wanted

[OutToWinPAHC]

Traded my LS6 240sx for a ECR33 with a RB25DET series 2 (swapped from Series 1). The old owner swapped in the following R33 engine with spec sheets and receipts for work. I am new to RB and there are certain issues I am addressing, but I wanted to know your opinions on the best solution.

As received

-Cometic Metal Head Gasket
-Wiseco Pistons .20 over
-Eagle Rods
-Custom Turbo Manifold by Element Racing in Utah ( equal length runners)
-Garrett 60 Trim T3 .63 A/R Turbo
-SS Oil Lines
-V 33mm external WasteGate with screamer pipe
-ISIS Intake Manifold (freddy / Greddy type)
-DeatschWerks side feed 550cc injector
-1G DSM BOV (atmospherpic)
-Custom 2.5 inch Intercooler piping
-4" Intercooler Core
-1999 WRX MAF (on boost side after intercooler)
-Greddy Turbo Timer
-A'pexi Power FC with hand commander
-FC Datalogit tuning software

Issues were that the entire wiring harness was hacked up. Since he converted from series 1 to series 2 he located a harness, but items were missing and he ended up making one from about 3 and the work was bad. I sourced a good harness from Pride Performance and swapped it out half way. I also noticed spliced wires is the lower harness and removed the intake manifold to see what was doing and found a mess there too. I am going to rewire this, then perform a wire tuck (since I need to lengthen the TPS and TPSW for the aftermarket intake manifold).

Questions

In discovery I have notice the throttle body coolant hoses have been removed and capped off. I assume that these should be connected back together? This is what I did with the old LS motor of mine.

The oil filter housing has a massive heat-sink with coolant lines in and out. My guess is that this is to maintain similar operating temps between the both. Is there a way to remove this heat-sink? I rather not heat my oil after it's heated unless there is a T-Stat built into that.

Broken knock sensor ( no biggie )

No ECU o2 sensor... my guess is this was tuned set MAP closed loop WHICH I WILL NOT KEEP. I ordered the sensor, but due to not having a factor manifold, down-pipe, or turbo I have no idea where the ideal location is. I assume the down pipe within 10 inches from the turbo exit. Can someone tell me the distance from factor and maybe post a photo of the the factory o2 bung?

WRX Maf sensor make no sense at all. Since I am stand alone I will convert to Q45/Z32 and recirculate the BOV.

Intake manifold bolts seems a bit short, not much bit on the threads, is there a list of lengths that is ideal for a greddy / freddy intake?

The throttle cables have an offset pull with the intake manifold swap, is there something to fix this. I can see future issues in this area if not.

The I will download a similar open loop base-map and start fresh and retune after a Q45 Throttle body

Wanted

Looking for a very good Series 2 coil pack harness, a bad series 2 MAF (weird I just want it to make something), AC compressor with brackets and bolts, and thats it for now.

the throttle body line you can leave it or connect it back up to you. its lets the motor idle high when cold and then thermostat opens and lowers it. only there for cold starts.

the oil filter cooler assembly can be removed and replace with a stud from Rawbrokerage. just cap off the coolant

gonna probably have to make custom bracket for cable.


the bov is basically the same as stock except vacuum nipple in different spot

wrx maf is for blow through which rb's likes runs smoother cause it can tell what kind of air is entering though throttle body after being cooled and its closer then entering from turbo inlet. people do same thing with z32 maf they open it up seal it to run blowthrough setup but dont know how much psi it can handle

[OutToWinPAHC]

Yeah but I assume for flow the coolant lines are not supposed to be capped off. The lines should be connected back together right? I figured I would have to make my own throttle bracket. I have found photos of the o2 bungs location so I am good with this

More input?

[RRRRB]

i think i would have kept the 240

nah car is so clean
