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?

      I need more than help to finish my R33

      Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.

      Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.
