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

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

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

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.

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 ?

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.

    • Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys
    • Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels
    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.            
    • Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
