Rb30de Help

[N0Vus]

Ok, to start I have tried to search for answers

So ive picked up a RB25DE R32 engine with loom and ecu and all i want it for is head loom and ecu.

Now I plan on mating it to a rb30 bottom end.

My question is has anyone run this set up on the 25de ecu with the correct sized injectors to suit the extra half a litre?

Is it safe enough to drive? Not worried about top end, as long as itll be safe for daily driving.

What are the afrs like?

Id plan on chucking in a wide band sensor to keep and eye on anything.

My reason for this is my 20e auto cefiro is shitting itself, my 180sx isnt done yet, with out that being done I cant do my 2j conversion, so 30de is done from what I have and will in long run be put into my other car once 2jz swap begins

Cheers in advance for any help or insight

I would think you need a Nistune to make it work.

Its always best to run an aftermarket ecu with this sort of build because you have a larger field to tune, although it shouldnt be needed
