hay there people,

im trying to find out if i will hav trouble wiring up a rb25det using a r32 20det loom and ecu.i know about the side and top feeddz.

will i have to wire in a ballest resister???????

also do each injector hav positiv and negative pins on them or??? :laugh:

also how can i tell if my ecu is 20det or 25de.iv look at alot of dif ecu and the numbers on the front cover but im hereing alot of dif storys please help

As I mentioned previously, the rb20det silvertop loom will go straight onto a r32 rb25 head only. It will run a r33 head as well, but the injector plugs will need to be changed, and it will also have no VVT solenoid plug. Nor will a chipped rb20 ECU have the ability to run VCT.

So if your not going to run VCT, and your able to change the injector plugs then it should be fine.

You will not have to wire in any resistor, both are high imp injectors. Each injector will have a common 12+ wire on it which goes back to your IGN relay. The ECU then pulses ground signals to each injector in order to fire it.

Each injector on the negative side will have a different coloured wire indicating the cylinder number on the ECU pinout.

Just completed a 30det in my 32,used a rb20det loom and had no troubles,also using a mapped 20 ecu,nit sure if any of this helps,head was a r33 rb25de s1

im doing to transplants atmo.got 30e bloc with 25de vvt head.runing 32 loom and gen1 25de chiped ecu.what sort of injecters did u use.im thinking of using sr20det 1z

ok thanks is there a way to hard wire vvt to a 20det ecu?its geting dynod on friday and has piggy back in it(no afm)

also on my own project 30e 25vvt head,im runing gen1 25de ecu chiped for plus t and was told i kan hard wire vvt off the oxysensor if i put a 5volt relay or sumthing b4 it gets to ecu??????? chers guys

    • The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.
    • It's almost certainly the same as the one next to it.

    • South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
    • Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers
    • Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.
