Rb20 Ecu Into R33 Series 1.5. How Hard Is It?

[Daboss]

Hey forum just need to ask a few questions about the topic as I have searched but still just a little confused. Ok as the topic states I want to put a remapped rb20 ecu into my 95 r33. Cant afford a pfc so going the cheaper route. What I want to kno is that like the series 2 I do not see an igniter pack at the back of my engine just a plug( no black box ). Does this mean I will have to get an igniter pack in order for the rb20 ecu to b able to work with my car if so how to i integrate it into the system, also do I use the series 2 ecu diagram in order to see what needs rewiring? I also know that the rb20 ecu doesn't have vct control and I was looking on the hks site and saw two items, the rev ad and the rpm signal level converter, I wanted to know which of the two is suited to run the vct or if there is a cheaper alternative I can go with. Thanks for all the help.

the ecu will work, not mods required

series 1 R33 ecu's can be used on series 2 motors also.

hey from what i understand from your post you want to put an igniter on a series 2 engine? if so wont you have to change the coilpacks as well?

Thats what I am asking I don't know. It is not really a series 2 engine it's a 1.5 doesn't have the igniter pack, but has the two plugs on the tps with just one really connected. I don't want to put an igniter pack there just WANT to make sure what it is I have to do so when I get my list of parts and replace the ecu I don't hit a wall cus I left a part out. If its a straight swap I am all for it but if I have to make a few mods I just want to kno what they are, I already kno about the vct have that covered now its just if I wil have to make any more mods or is it just a straight swap.

do another search.

If you use the rb20 ecu you will have to add a external device to trigger the VCT. if you dont you will lose down low power.

Yea I Know. What I wanted to know was are there any other mods I will have to do or is it a straight swap? Will I have to rewire anything on the ecu or is it just a plug in and everything works except the VCT of course?

IIRC rb20 ecu is virtually straight plugin for rb25 minus vct.

To control vct, and old trick I know of is to use a modified shift light (usually works out cheaper) that triggers the vct solenoid instead of shift light, on most units it also means you can adjust when it kicks in.

i looked into 300zx ecu awhile ago as you just have to swap round think 20 or so wires and 300zx ecu runs vct so no stuffin round other than the wiring... i was ment to do this but well i have no idea why i havnt ahaha damn....

[Adriano]

Shouldn't need to worry about the ignition system, both have external igniters, ones at the back of the head, the other is in the coils. You can get a kit from jaycar to control the vct(you may need two of them, one to swith on, one to swith off) Im pretty sure you need to swap two injector wires, as they are wired in a different order. What remap are you going to run?

[Simon-S14]

just to clarify once again

you dont need to swap any wires or do any mods to anything EXCEPT have an external VCT controller (should you wish to run it.. i didnt) and the rb20 ecu will work once its mapped.

Ok good one other question if I was to go the z32 ecu route would a turbo or non-turbo ecu matter?

[Simon-S14]

no, since it gets remapped anyway, same with RB20 ecu, u can use a non turbo one.
