[MAD R33]

Hi guys

i just put a Neo in My R33 GTST S1

my mate think the r33 S1 ecu will not work

need info on how to wire R34 coilpacks to R33 S1 loom

and looking for anyone on what i should do or look out for

and what ways should i go with loom and ecu

i got told you can bolt all r33 stuff to the Neo motor and use r33 loom

any info will be good thanks

Get a series 2 loom

Dude do yourself a favor and buy a R34 RB25det neo ECU+loom.

Why root around buying series 1 and 2 RB25det parts for your NEO engine? Neo loom and ecu is a direct plug and play with minor modification.

its a direct plug and play into the engine yes but not the car, you would have to wire the neo loom to the car, not difficult if you know what your doing.

but you have a point.. it will give a better result. you can then use the nistune on the 34 ecu also

R34 loom as to be wired in to your dash loom

so many people have done NEO swaps and still use there own Loom

I reckon would be easier just mod your current loom to fit.

Thank you that what im trying to tell my mate...

[MAD R33]

need more info guys...will R33 S1 power NEO motor ? and will RB20 nisstune power a NEO ? and putting in R34 loom and ECU in R33 S1 gtst what will be need to be done to make all of it work ? need as much info guys plz thanks

[Simon-S14]

S1 loom uses a separate ignitor this wont work with the neo coils and you wont be able to fit s1 coilpacks in there. So the EASIEST way to make it all work would be to run a Series 2 RB25 loom, it will plug into your 33 no worries, gets rid of the ignitor and then you can run neo coil packs. The RB20 ecu will run it no worries.

Adapting the neo loom and running the neo ecu with a nistune would give a better overall result but at the expense of more work since theres a fair bit of rewiring to make the neo loom fit your r33.

if i was to go R34 loom and ecu

can i still use the R33

power steering pump

R33 air con

R33 ABS pump ?

[Simon-S14]

yes you can still use all those things HOWEVER making the abs work will be very time consuming.

just get a s2 R33 loom

i have the s2 coilpack plug to go to the ecu loom so cant i use the r33 s1 loom and wire that s2 plug on there ?

[MAD R33]

have a R33 s2 coilpack plug. can this be wired to work on the r33 S1 loom

lol

do whatever man. im done giving advice on this topic

[Dylank]

Hey mate how did you go with the swap and what route did you take with the loom/ecu

[GTSBoy]

He was last active nearly 10 years ago. Thread necro no likely worky worky.

The best advice is clear out all the old crap, use an aftermarket ECU, build a complete new loom from scratch.

The next best advice is use an R34 engine loom & ECU, adapt it where necessary to mate to the R33 body loom. Then at least you have a Nistunable ECU.

The worst idea is to keep any of the R33 stuff.
