Lude Generation

Hi guys im sure this has probably been covered before but does anyone know how difficult it is to swap out a h22a5 enginge for a h22a7 in a 5th gen.

P.s. I dont know if it makes any difference but I dont need to worry about the 4ws system as mine is a 2ws.

Any input greatly appreciated

Is putting the a7 engine in the 5th more straightforward than the 4th gen as my friend is also interested in doing this & he has a 4th. Sorry for so many questions lol

pretty easy buddy just a straight replacement really what ecu you intending on using?

Im not to sure on this yet I need to do some googling or ask the powers that be on here for some suggestions

it will run fine on the a5 ecu but wont get the best out of it until you either use an a7 or 8 ecu but might cause issues with the immobiliser

What would be the best ecu for mapping as I intend on doing a full exhaust system and intake?

wont need mapping with just an exhaust and intake.

if your going for a ported head and cams then ultimate would be a standalone ecu like an aem the problem with the 5g is that it is obd2 so doesnt like ecu tuning so an obd1 conversion harness and a p28 ecu with hondata is a great start

So there would be no benefit of getting a mappable ecu just for a 421 manifold decat exhaust and intake

not really buddy actually there would be a benefit but not enough to buy a standalone ecu unless your planning on going all out at some point

I have been thinking of an all out option but I dont think it would be suitable as a daily drive. Plus if im going all out I want forced induction which I will probably use a h5 engine for so its easier to replace if it goes wrong
