2002 rsx base with a k20z3 swap?

Post by Pospeshil »

I have a 02 Rsx base and got a hold of a 09 civic SI K20z3 motor built up... what ECU do I need to make it run?

this is what the K20z3 has done to it

Cams are kelford stage 1
pistons are Wiseco heat treaded
rods are stock and balanced
all new bearings
scunk2 s/s valves, buddyclub springs and retainers
Head is studded with APR bolts
3 angle valve job and more
520cc injector

It was set up with a ct supercharger with a ecu relash I have that ecu too but I don't think it will work in my 02 RSX right?

If using the 5 speed transmission then the stock (PND) ECU is fine, otherwise you will need a type S ECU.

I’ve got a base 2006 rsx, manual 5 speed. I just bought a civic SI k20z3 along with the 6 speed transmission. I plan on swapping both the engine and transmission, do I need to get a type S ECU also?

I was just about to eBay an 02-04 ECU for a base model, but decided to double check.

Sorry to revive an old thread but I think it makes sense to contain the discussion here rather than creating a new one. I’m assuming the answer is the same for all Base RSXs

I would recommend using the Type S ECU.

Another question then is should I get an 02-04 Type S ecu as well? Based on everything I’ve read I need to use the 02-04 ecu.

And Hondata will provide the harness I need right?

Yes it must be from an 02-04. When you purchase through one of our dealers you need to make sure you purchase for an 05-06 RSX.
