S13Gene

Anyone know were i can buy these? cant seem to find a solid lead on them.

Alright, you have any idea what pin it is on the ecu? Should be battery voltage correct?

Chassis: USDM 1998 240sx (kouki) Engine set: ER34 Rb25det (Neo) Mods: Cometic headgasket, Arp headstuds, Isis Intake manifold (r33 IACV not wired in) Aftermarket no name fuel rail, Aeromotive 13109 FPR, FMIC, Q45 Throttlebody Pros: Starts with Brake kleen/ether, will idle, run an boost 12psi with no problems after started. Things ive checked, CAS, injector and pulse also drivers (on ecu "battery voltage), Have Spark on all 6, fuel pressue (43 an holds ign on), Compression, IGN signal +, Timing Plugs an gap.. Problem Dont matter if it is hot or cold i have to spray it with ether to get it to start. Unplugging the TPS or MAF does not help, this problem appear to happen after going to the Aeromotive FPR as with the stock rail i modified to work it started every time. im using topfeed injectors double 11mm for upper an oem neo lowers oring on brand new r33 cushions (sidefeed) found 3 of the cushion to o ring leaking (spray with brake kleen an need a misfire) thats not the reason it no starts though.

Well i got the fuel system installed an now have no start unless i use starting fluid, Fuel pump, CAS, injectors, an Fuel pressure are all correct. i have even checked voltage at the injector drivers, and coilpack drivers on the ecu.

No results found for 'r34 with r33 iacv'. even tried using the it differently.

So i need some help getting a S1 Iacv wired up on the neo, through some research i found that the brown plug is what i need to wire in to have a decent idle after accel, right now im heel toeing to keep her alive. Anyone have an insight?

I actually got it fixed last night, Now i just need to wire in the neo to s1 iacv, an set the q45 tps.

Well i diag it yesterday, For sure have leaking injector cushions/insultors were the injectors sit in the intake manifold (freddy) cant find any information on what size cushion i need for the stock topfeed injectors on the Neo engine.

Hello All, Im looking for OEM part number for the Rb25det neo topfeed injector cushions! Also has anyone ever had problems with a Freddy manifold leaking inbetween cylinder 2-3?? im pretty sure its just the cushions of a RB with sidefeed but just curious if its a problem..

Finally got to do some work on the Neo today. pic is attached,

Hey Im Gene currently have a S14 kouki Rb25det Neo swapped with some mods which is under going some work at this moment. I sold the car 2 years ago it was wrecked an swapped over from a zenki (black s14 in attachments) to a kouki which the owner didnt complete everything an sold it back to me knowing how nice the car was before an knowing i will create another monster..... Real LMGTS 18x8.5, Now has ISIS FFIM, q45 TB, full suspenion soon to have bigger turbo, injectors, AEM standalone, and a cage. i will get some up to date pictures this weekend of the kouki. Im from the Gulf Coast Region southern United States, Florida to be exact. Glad to see a US part in this forums.

Problem solved..

Alright update on whats going on. 3.33v TPS closed adjusted it as much as possibe and could only sqeeze out 2.567v made it better but still not right.... Im going to replace the TPS saturday, When thing I cant find is what the bottom 3 strands of wires are used for ? is that for the a/t control module?

Alright guys i have a USDM s14 with a RB25det Neo, FMIC, walbro fuel pump, Wiring spec Harness Drives idles etc .. Anyways I used Consult 2 to read codes out of the OBD1 port and some of the codes i knew i would have IE Boost sensor, ABS, TCS but its throwing a TPS code also which it has thrown 2 times. I have 6 wires coming off my TPS so im assumming that it is a Auto Engine? It is also throwing a TAC module. Idle is 1300 when warm just found that out last night via Consult 2 cold is 1700 when using Consult i can manuely turn on the ACC and drops to 750ish and holds. So to get the Point is the TAC needed? and is it throwing TPS code cause only the top half of the TPS is plugged in?

Alright so I ended up just tracing what wire i could back to the ECU, Found that one Connector is for Consult, and one is FPCM buy the ECU, still unsure about the one in the engine bay though i have a feeling its hicas stuff.
