What EJ20? SOHC? DOHC? Be specific with these sorts of questions

If it's SOHC, pretty damn easy, but you may need to swap the 2.2's intake manifold to it, that will eliminate any strange little differences. Don't forget some EJ20 SOHC's are MAP sensor driven, not AFM driven, so there's a lot of variation.

If it's DOHC, you'll need to transfer the SOHC engine loom to the DOHC manifold, and extend any wires that dont reach right. Any 20D will have red injectors, so you're all sorted for that. Hopefully the TPS will be the same generation, otherwise you'll be doing some custom work for that.


As for the ECU side of things, that will be fine, it should self learn any minute differences in air flow to fuel required. Getting a new o2 sensor will ensure it runs good.

<Shale>: Blighter doesn't really have an accelerator pedal, it's more just a loudness pedal. You can change volume, but you won't go any faster.

<Reuben>: I feel like when you stomp the throttle in Blighter, it's like you've startled an old man!

Only when increasing displacement by more 25% though... otherwise they're the same series engine...

I believe it says a change of displacement does not say up or down

Meh, looks the same to me................... TBH youe average wof guy probably wont be able to tell whether its a 20/22/25. So long as the bay still looks fairly standard you should be sweet. My Nissan Safari passed a warrant at VTNZ with an uncertified turbo conversion, never even questioned it. But at the end of the day it is up to you how you go about it.

Oh yeah, Blighter technically needs a cert for the rear disk conversion, manual conversion, and 2L conversion, heck, maybe even the SPFI-MPFI conversion, but he gets through wofs fine, it's all factory BC parts, installed like factory, the wof guys know, but realise it's all good. Half of Queenstown's fleet of 250T's are running on DOHC and SOHC 2l's and 2.2's, and i can never think of any time that's ever been a problem. Only times VTNZ pick problems are when the're performance parts, we had them fail shale for a brembo conversion... only cause they stick out like a sore thumb!
