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.

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.

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?

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?

      Cleaning my wheels 😍

      By PranK · Posted

      A little follow up here on the ceramic coating.  We've had storms galore here and I've done a few ks, enough to gross them up  Consensus is that they didn't get as dirty as usual, the coating definitely repelled a little of the dirt and I think they kinda snowball. They get a little dirty and then they get dirty faster which makes sense. Cleaning them regularly would allow them to protect better.  Cleaning was a breeze. I tried first to just hose them off which, unsurprisingly, did nothing. But, making the wheels wet and then just wiping them over with a used but clean microfibre cloth was all that was required. I didn't need any cleaner at all, just water and a cloth. The wheels look amazing again.

      Gave her a nice wash today and took extra time to clean off the tree sap and tar and crap. We have a usable garage now so she'll stay cleaner longer. Took a few snaps in some nice light afterwards.

      OK, solid mount Z1 diff brace is in, pretty straightforward, it picks up 3 diff hat bolts and ties them to 2 support bolts on the subframe. Pretty sure someone else on here said they had reduced axle tramp with this but mine was already pretty good for smooth wheelspin, and still is....will see you this goes over time and whether I end up with a broken rear diff hat

      Mistakes were made, my R34 Story

      Ah yes, but the part in my hand was actually painted and fitted by me! I knew any front lip was likely to be sacrificial but I've had to fix it twice already... by the time I buy a fibreglass fixing kit, sort out sandpaper blocks, buy some fibreglass filler, body bog, spend the time and effort for a 'Greg' result... a new one being $290 seems like it's the better way to go and spray that with bedliner/raptor coat and we're all pretty again.. Would have preferred it last more than a month though. Them's the breaks I suppose.

      I find it funny that the USA is finding out all this really really weird stuff, and people from the USA are coming here treating it like gospel, yet, all the info on solving those issues is here on these forums for the last 15 odd years... Also, I know how much heat it takes to ignite the hood lining of an R33 skyline. I worked it out myself... It also took a LOT of time, and heat for it to do it... Big single, and I needed to drive the car, so retarded the timing off to "protect it". Yeah, that was a bad move for cruising on a freeway with only 15 degrees of timing on it. That was a lesson I learned around 2009. So that's over 15 odd years ago. Aligning water and oil, that's identical for any turbo engine, it's not Japanese specific. If a shop doesn't know how to make sure the core is rotated the right way, then they shouldn't be touching any turbo engine. That's not a matter of "We haven't had Skylines for that long here"...
