Because if I run an RB25DE ECU, I need to rip apart the dash and swap ALL the wiring over don't I? which will be a kent of a job to do! :D

I'd rather get the loom adapted to the SII RB25DE and leave the R32 RB20DE ECU in.

You will not need to modify the wiring for the dash only the engine loom. I have prepared plug'n'play looms for a number of members of this forum and the most popular is dropping an RB25DET into an R32. I remove unnecessary wiring from the R33 loom and integrate specific wiring from the R32 (eg climate control inlet water temp and fuel pump resistor - not applicable in a non-turbo R32) and more importantly the loom plugs which connect to the R32 body wiring (eg 8pin plug near power steering reservoir and 3 plugs near ECU).

The R33 RB25 has a common power feed to the O2 heater, boost solenoid and VCT. I separate the O2 heater power feed and connect it to the dedicated feed from the R32 loom and then supply separate power for the boost solenoid and VCT by connecting to one of the main loom power feeds.

Hope this helps.

Cheers

I did this conversion to a cefiro as couple of years ago.

it is worth while.

my r32 rb25de stock with 21/4 " exhaust made 115 rwkw this made the car very nice to drive .

my previous rb20 de in a skyline made 86rwkw for a comparison. so basically it makes the same power a a stock boost rb20det. we didn't develop the car any further but i feel there was another 10 to 15 rwkw in there with some tuning extractors and cam upgrade. motor dropped in fine no issues stock manual gear box was fine as well.

cheers

    • Read the ECU for fault codes or have someone else do it. A faulty coolant temperature sender is usually listed in ECUs. If the sensor itself is not busted it can also be a bad ground connection. Or in a really unlucky case, damaged wiring.
    • Can't be a Futjitsubo as those are made with a flex piece and Reimax is smaller in pipe diameter. If anything it is closest to a Mines pipe, but evidently it is not an actual Mines pipe.   Classic word humor
    • Alright I will try to not forget.   As GTSboy replied to you already, problem is mainly the mismatch between the actual exhaust part and the denomination in the papers. That basically just looks like tampering to a cop, if they were to check your car and notice. If it had been done right they would have clarified it to be a custom pipe and just given it a certain part number that you have to engrave or weld onto the pipe. I will definitely inquire on what to do. Changing the pipe wouldn't be my favorite solution as it costs a bunch of money and the cat was fitted with the front pipe and exhaust under the car, and if the front pipe flange does not sit in the OEM location the cat will need to be refit for any other pipe to work. It also usually doesn't need a brand name or something like that, but more something like a part number. Usually for exhaust parts, on silencers and cat units specifically, there is a badge that reads the certificate number that belongs to these exhaust parts under EU regulation. You get these numbers after you put a part or group of parts through the tedious testing according to EU vehicle legislation and they pass. You can find these "part numbers" on various parts throughout a EU vehicle. On windows, headlights, engine parts, seat belts and so on. All these parts have gone through standardized testing and acquired a so called ECE or EG Certificate that makes them legal to use by themselves in all countries that adhere to these standards. You can also not alter these parts in any way, if you do they become illegal. An example for stampings on an exterior lighting part, the people who need to know can find the documentation for this unit in a database. I do not know what all the standards and so on mean.
    • If that was the case I suppose you could call it "Mein's" brand....  ... I'll see myself out... 馃槄
